Challenges Facing Negotiators At the Davos forum of January 2014, a group of 14 countries pledged to launch negotiations on liberalizing trade in ‘green goods’. This move has been welcomed both as a sign that the WTO is still alive, and that a group of countries may, after all, take measures to reduce barriers to trade in Environmental Goods (EGs) and in Environmental Services (ESs) as they had been mandated at the launch of the Doha Round in 2001.1 At this stage, the commitment is only to a reduction in tariffs on EGs. Negotiations on ESs are off the agenda as they are still pending the outcome of the Trade in Services Agreement (TiSA) negotiations. Although the immediate objective is to reach a Plurilateral Agreement (PA), which requires consensus by WTO members and hence a ‘critical mass’ of participants, any agreed reductions by the group of countries will be extended to other members. In 12 years, negotiations among WTO members on the reductions of barriers to trade in EGs and ESs have lost momentum. The PA route --which has already delivered progress on Government Procurement and on Information Technology products-- could well become an alternative route to the multilateral and regional approaches to reach a negotiated agreement that would slash trade barriers in green goods. The Davos announcement is intended to extend the reach of the tariff reductions to a larger group of countries than if these negotiations had taken place in the APEC regional setting. The countries have also agreed to start negotiations from an existing list of 54 goods drawn by APEC members in 2012, a progress over the previous multilateral negotiations where countries failed to agree on the approach. However, will the list be extended to more goods and to non-tariff barriers (NTBs)? And how significant are these negotiations likely to be since ESs may not be included? Aside from China’s participation and the possibility that reluctant WTO members like Brazil, India and South Africa might join in, is this initiative largely symbolic? In short, what is the significance of this initiative (henceforth the Davos negotiations)? Despite the WTO’s recent failure to deliver negotiated agreements, its other functions (monitoring government decision-making, resolving disputes) remain. Yet, it is still the case that, for many, the ultimate purpose of the WTO is to deliver negotiated deals that reduce discrimination. Knowing what is at stake as negotiations start is useful to better apprehend what can be achieved when negotiations first take place among a smaller group of countries. With a world moving towards variable geometry, an issue specific PA can offer advantages 1 The Round has been dubbed the Round for the “Developing Countries and for the protection of the environment”. The Doha ministerial decision of November 2001, paragraph 31(iii) stated that “…With a view to enhancing the mutual supportiveness of trade and the environment, we agree to negotiations, without prejudging their outcome, on: (…) (iii) the reduction or, as appropriate, elimination of tariff barriers to environmental goods and services”. Negotiations take place in the Special Session of the Committee on Trade and the Environment (CTE in Special Session or CTESS). The other two mandates under paragraph 31 are on coordination and dispute settlement and on information exchange with Multilateral Environmental Agreements (MEAs). 3 over a Preferential Trade Agreement (PTA) as it avoids the linkage issue and is open to newcomers wishing to join the negotiations. A PA should hence be able to sustain greater multilateral trade cooperation (Hoekman, 2013). By documenting what is now on the table and the successes and shortcomings of the twelve years of the Doha negotiations (see Melo and Vijil, 2014), this paper informs on what might be hoped-for from issue-specific negotiations among a smaller group of countries compared with a counterfactual PTA situation. The case of green goods examined here could also serve as a benchmark for other areas where dialogue, learning and negotiations could take place among a subset of WTO members, such as in the case of investment and competition policies. The more immediate objective of the paper is to inform about the likely gains of the agreed upon Davos agenda which only includes tariffs (and perhaps NTBs) on EGs and to identify which complementary steps should be undertaken to reach the ultimate objective of global free trade in green goods and services. This appears a timely contribution to negotiations, as suggested by the comprehensive public consultation launched in June by the European Commission which aims to collect the views of the business community and the general public on barriers to trade in environmental goods and services 2. As emphasized in work by the OECD and others, trade in EGs often embodies ESs with strong complementarities between the two, especially for developing countries that carry out environmental projects that embody EGs and ESs. This implies that reductions in policy-imposed barriers to trade in ESs should also be pursued. As discussed here, these restrictions are difficult to assess, but qualitative indexes comparing commitments to market access and national treatment for ESs with those for other services give an idea of the extent of restrictions and of differences across countries. Section 2 reviews the first challenge facing negotiators: the ‘technical’ difficulties encountered in identifying EGs and ESs in previous negotiations that will extend to the current negotiations. Section 3 documents the tariff structure for two lists of EGs for the Davos group members. These are then compared to those for a larger group of 120 countries to point out that the Davos group members have only small leeway to reduce protection. Estimates of import response to a 50% and total reduction in tariffs are also provided. As an indication of the gains that might result from a reduction in barriers to trade in services, section 4 then reviews what has been achieved in terms of commitments to market access and national treatment. Section 5 concludes. 2. Obstacles in Classifying EGs and ESs Since all human activities have an impact on the environment (we are in the ‘anthropocene’), it is very difficult to measure progress (or lack thereof) relative to other activities that have a lesser impact on the environment. For EGs, once defined, a reduction or elimination of tariffs and non-tariff barriers should help diffuse products and technologies 2 http://trade.ec.europa.eu/consultations/index.cfm?consul_id=180 4 necessary to reduce environmental damage (e.g. pollution at source or at end-of-pipe). But very often these products and technologies are part of environmental projects that include ESs (e.g. wastewater management services, water collection and purification, recycling). Thus, environmental projects have a great degree of ‘jointness’ or complementarity between the services provided by EGs and those provided by ESs. Moreover, as summarized in several case studies, ESs included in environmental projects include an increasingly large array of services that extend beyond those that are classified as ESs (e.g. business and engineering services, telecommunications) in the UN Central Product Classification (CPC). 3 Complementarities are particularly strong in developing countries where trade in environmental goods and trade in environmental services often involve the sale of entire plants. Hence a reduction of barriers to trade in EGs unaccompanied by a reduction in barriers to complementary ESs may have little effect. These are the difficulties facing the negotiators of the countries who pledged to launch negotiations in the WTO on ‘green goods’. 2.1 How extensive is the classification of environmental goods? Even though the negotiators have now agreed on a list of 54 goods as a starting point, they “…are committed to exploring a broad range of additional products”. Divergences in perceptions about what is an EG and the inadequacy of the Harmonized System (HS) remain obstacles for any envisaged extension to that list. One solution is to use “ex” headings for identification at the national line level, the implication then being that within an HS-6 level line, reductions may only cover a subset of products. For instance, on average, the 14 Davos members have 118 national tariff lines at the HS-6 level (see annex). Extending, say, the HS system to distinguish energy-efficient refrigerators from others still does not solve the problem of multiple end-use, which besets many Goods for Environmental Management (GEM). 4 An alternative would be to use the project or define-by-doing approach which did not get support during the Doha negotiations. The drawback is that it is temporary and up for capture by interest groups. Next, negotiators have been bogged down by the treatment of Environmentally Preferable Products (EPPs) and ‘like products’ at the WTO. For some, an agreement on EGs should take into account how environmentally friendly a product is in its production, consumption or disposal. This calls for a life cycle analysis which might entail distinguishing goods by their Processes of Production Methods (PPMs). While differentiation for statistical purposes should be possible, this would run into an interpretation of ‘like products’ since WTO 3 See e.g. Kennett and Steenblik (2005), Steenblik and Geloso Grosso (2011) and section 2.2.. 4 Differentiation according to end-use is a possibility. It was applied to a list of products in the 1973 Agreement on Civil Aircraft where only articles with a civil aircraft manufacturer could qualify. Artificial distinguishing features were also applied to control trade in pharmaceuticals in the Doha Declaration on TRIPS suggesting that a label “environmental” or “non-environmental” could be used on a product (Steenblik, 2005b.; p.79). 5 agreements require that imported products receive no less favorable treatment than ‘like products’ of national origin, such as an energy-efficient washing machine or the use of low- emission technology in aluminum production. 5 Along the same vein, criteria are lacking to judge what is “environmentally friendly”. Apart from the divergence in preferences (conceptions of the “environment”), this is also due to the hurdles facing the completion of a life-cycle assessment as a same good may be used and disposed of in different ways. Again, using “ex” headings for identification at the 8-digit or 10-digit level would be part of the solution. Among the 411 products on a WTO combined list, more than two-thirds only appeared on one submission list, an indication that the perception of EGs differs widely across countries (Balineau and Melo, 2011). As examples, Steenblik (2007) and Hufbauer et al. (2009), stress that the use of bio-fuels to save on energy and reduce CO2 emissions is, at best, doubtful, not to mention that today’s cleanest available technology will change as technological progress occurs, calling for regular updates of the list of goods that would benefit from tariff exemptions. Moreover, the identification of EPPs requires an efficient disclosure mechanism, which can be very costly when attributes are not observable in the final product (e.g. efficient third-party certification for “credence goods”, calling for an international standard and certification process). 6 Several lists of EGs have been drawn. After many rounds of submissions, in 2010, 13 developed countries proposed lists resulting in a combined list (the ‘WTO list’ of 411 products that included many of the products in the earlier OECD and APEC lists). Another negotiated list is the “Friends of the Environment List” of 154 products. Then in 2011, Australia; Colombia; Hong Kong SAR, China; Norway; and Singapore agreed on a supposedly non-controversial ‘core list’ of 26 products. An examination of the products on these lists showed that countries mostly submitted goods in which they had a revealed comparative advantage, which is commendable on efficiency grounds. But submitters also systematically excluded from their submission lists goods with tariff peaks, confirming mercantilistic behavior (see Balineau and Melo, 2013; and table 1). It is quite likely that this behavior will prevail when it comes to adding any further goods to the APEC starting list of 54 goods. Indeed, the APEC list of 54 products is the outcome of trimming from an original list of some 200 odd products. Melo and Vijil (2014) reported estimates with both the ‘core list’ of 26 products proposed by a group of countries in 2011 and the ‘WTO list‘ of 411 products drawn by adding all the lists, obtaining similar results with both lists. Since agreement on an extended list may be difficult to reach, we concentrate here on the APEC list of 54 products, 5 The jurisprudence at the GATT/WTO on PPMs is still in flux. Moreover, several members, including developing countries, are against designating PPM-based EGs. Developing countries actually fear that this would open the door to discrimination against their products based on other than environmental concerns (“social concerns” for example, based on the absence of legislation on domestic workers’ rights). 6 Goods whose attributes cannot be observed before their purchase (“search goods”, e.g. the price of tuna) or their consumption (“experience goods”, e.g. the taste of tuna). For example, consumers cannot know if tuna have been fished in dolphin-safe conditions before, during, or even after consumption. Disclosure of credence characteristics requires other mechanisms than repeated purchases and reputation. 6 but also report some estimates with the most comprehensive WTO list, as an estimate of what might be at stake, should countries agree on an all-encompassing list of EGs. 2.2 Classifying environmental services 7 The difficulties facing the TiSA negotiations are an order of magnitude greater than those facing negotiations on EGs. It is therefore likely that any negotiations will take place around the WTO Services Sectoral Classification (W/120) list, though the inadequacies of that list will present a major hurdle in reaching agreement, even for OECD countries. Production is increasingly taking the form of trade in tasks (i.e. services) as opposed to trade in products. Services play an input function through space (transport, telecommunications) and time (financial services) as well as direct inputs into economic activity as they generate knowledge and human capital. Recent developments in the study of global value chains show that services may account for more than 50% of exports when measured in value added (OECD, 2014). The linkage between intermediate services, regulation, and policies is still largely unexplored, if only because of the lack of data both on services and regulations (services do not meet customs for registration, and regulations are, at best, imperfectly captured). Unlike goods trade flows for which data exist because they are taxed, services-- except for labor and FDI flows-- are not directly observed crossing borders. Furthermore, since disembodied trade is becoming more important as the burden of proximity has loosened, the tracking of flows is poor and, at best, spotty. These characteristics make it difficult to draw an informative list of ESs. Negotiators would like to have indicators of trade restrictiveness measures for services. Building indicators implies taking into account two characteristics of services: (i) the proximity burden and, (ii) the “margin sector”. A proximity burden is imposed on certain forms of services because, unlike goods, they cannot be stored. Even though technological change has led to the geographical splintering of the production chain for both tangible inputs and for services, trade in services may require a heavier dose of local presence of suppliers in the mix of cross-border and locally-produced services than in the case of goods. In addition, services provision will often have “jointness in production” as complementary inputs—including other services—are needed to allow effective exchange (trade) to occur. The proximity burden is handled in the GATS four-way classification of services: • Mode 1: No movement of either supplier or buyer (direct cross-border trade); • Mode 2: Customer moves to the country of the provider (tourism); • Mode 3: Commercial presence through sales of an affiliate (multinational enterprise/legal person); • Mode 4: Temporary movement of natural persons to provide services. For modes 2 and 4, indicators of reducing restrictions on the movement of natural persons and providing market access on non-discriminatory terms (and guarantees for repatriation of 7 This discussion draws on Geloso Grosso (2005), Kirkpatrick (2006) and Francois and Hoekman (2010). 7 funds as provided for in the large number of Bilateral Investment Treaties) for foreign firms can provide a rough approximation of trade liberalization. For modes 1 and 3, much like the choice between vertical and horizontal FDI, the mix of trade and coordination costs (inclusive of policy-imposed trade barriers) will determine firms’ choices. Changes in trade policies that affect the balance of these costs (e.g. contract costs vs. management costs) will then determine the choice of mode, if choice there is, since modes of supply may be complements or substitutes. If the unconstrained mode is the most efficient mode, and modes are substitutes, changes in constrained modes will have no effect while if modes are complements, a liberal policy in one mode would have no effect on the provision of the service. In addition, as pointed out by Francois and Hoekman (2010), barriers to entry (policy and natural), network externalities (telecommunications, finance), heavy regulation (communications, finance, professional services) all conjure to giving these services sectors market power especially since they are “margin sectors”, i.e. they facilitate transactions between agents. Indicators of policy stance for ESs would then need to capture not only regulation and competition for its own sector but also for downstream and upstream “margin sectors”, while recognizing that not all policies affecting foreign services transactions are discriminatory. Capturing these characteristics in indicators of restrictiveness will be difficult. Up until now, measures of restrictiveness are still drawn from the W/120 list, which is largely based on the Provisional United Nations Central Product Classification (Provisional CPC). The complete list of service sectors negotiated at the GATS during the Uruguay Round has 155 sub-sectors among which four sub-sectors are categorized as environmental services. These are: (a) sewage services (CPC Prov. 9401); (b) refuse disposal services (CPC Prov. 9402); (c) sanitation and similar sectors; and (d) other services (CPC Prov. 9404; CPC Prov. 9405; CPC Prov. 9406; CPC Prov. 9409). These include cleaning services for exhaust gases, noise abatement services, nature and landscape protection services, and other environmental services not elsewhere classified. The sub-sectors in this list are exclusive so a service sub-sector such as engineering services cannot appear twice as an environmental service sector and as a ‘standard’ service sector. Since there are complementarities in the provision of services across sub-sectors, any measure of barriers to trade in services based on the CPC classification is an inadequate approximation of the state of restrictions in the ES sector. Dating from the GATS commitments negotiated during the Uruguay Round nearly 20 years old, this classification is outdated. This narrow GATS classification defines ESs as end-of-pipe 8 public infrastructure services, largely focused on waste management and pollution control. It fails also to reflect the current market and policy characteristics of the ES sector as the proximity burden has fallen, opening the road to linkages across modes and across services sub-sectors. Neither does it take account of the growing public sensitivity towards the environment which would call for more services sectors being classified as ESs, as well as the shift from pollution control towards pollution prevention through the adoption of cleaner technologies for production and products (OECD, 2003). Furthermore, as sectors in the CPC classification system are mutually exclusive, the CPC classification cannot take into account environmental services that fall within the scope of other sectors, such as business, construction and engineering, and education and tourism. Finally, as illustrated in case studies (e.g. Steenblik and Geloso Grosso, 2011), this classification fails to take into account that many operators, especially in developing countries, integrate the supply of ES with imports of EGs. As noted by Kirpatrick (2006), the liberalization of the ES is negotiated under the GATS while liberalization of goods is negotiated under NAMA (Non-Agricultural Market Access). 3. Barriers to Trade in EGs: Trends and Expected Effects from the Davos Initiative 3.1. Trends in tariffs and non-tariff barriers by income group We start with a comparison of patterns of protection for EGs and non-EGs for all countries, as a hope of the Davos communiqué is that participation will be enlarged, a requisite for reaching a plurilateral agreement at the WTO. The bottom of table 1 reports current (averages over 2010 and 2011) applied MFN tariffs for EGs (APEC list of 54 products) vs. all other (non-EGs) products for 120 countries at the HS-6 level (corresponding estimates for the ‘core’ list of 26 products are reported in Melo and Vijil (2014, table 1)). The data show several patterns. First, for all income groups, EGs are less protected on average than other goods, with average tariffs for EGs for each income group about half that for non-EGs. This regularity could reflect a combination of two patterns. Insofar as EGs are mostly intermediate-goods producing sectors, they meet the opposition to protection by downstream sectors, a pattern observed world-wide of intermediate-goods-producing sectors from final goods users (WTO, 2011 figure D-2; and Cadot et al., 2003). But it could also be that countries would only put on their lists products with relatively low tariffs. Balineau and Melo (2013, table 2) show that submitters of EG lists had a very low percentage of products with tariff peaks, an indication of mercantilistic behavior. 8 Second, protection of EGs remains highest in the low-income country (LIC) group with average tariffs of 5.2% at the end of period (see table 1, col. 1). This level is barely high 8 The difference between the TRI and average tariff levels are much greater for non-EGs than EGs, which partly reflects that products with tariff peaks are generally absent from the EGs lists (the TRI is also influenced by the variance of tariffs which automatically increases with the number of products considered). 9 enough for a bilateral barter among developing countries by a request-and-offer approach to be rewarding as it had been in the early days of the GATT. Thus, it is no surprise that this approach was discarded by negotiators. As to high income countries (HIC), average tariffs were 2.2 %, so their expected gains from participation in the negotiations would be from reduction in tariffs by developing countries (which explains why developing countries were generally opposed to a list approach, which would have resulted in larger tariff reductions for them under a proportional reduction formula). Taking into account that many countries are members of Preferential Trade Agreements (PTAs) that are mostly Free Trade Areas, actual applied tariffs are even lower than the MFN-based estimates reported here. 10 Table 1: Overall protection by Davos country and income group Tariffs only (applied MFN) Overall protection (Tariffs+AVEs of NTBs)) EGs Other goods EGs Other goods APEC list WTO list APEC list APEC list WTO list APEC list (1) (2) (3) (4) (5) (6) (7) (8) (9) (10) (11) (12) Tariff + Tariff + Tariff + Tariff Tariff Tariff NTBs NTBs NTBs (import TRI (import TRI (import TRI TRI TRI TRI (import (import (import weighted) weighted) weighted) weighted) weighted) weighted) Australia 1.6 2.8 3.5 4.2 2.8 3.9 Australia 8.5 27.7 12.6 55.5 9.9 43.8 Canada 0.6 1.5 2.8 3.9 2.4 4.8 Canada n.a. n.a. 12.2 68.4 5.8 40.3 China 4.8 6.2 7.8 11.5 4.8 9.0 China 1.6 5.3 15.0 47.4 9.9 35.2 Costa Rica 0.0 0.2 2.5 5.2 4.4 8.4 Costa Rica n.a. n.a. n.a. n.a. 0.4 5.6 European Union 0.8 1.3 2.5 4.5 2.8 5.0 European Union n.a. n.a. 0.0 1.1 7.0 24.1 Hong Kong SAR, China 0.0 0.0 0.0 0.0 0.0 0.0 Hong Kong SAR, China 0.0 0.0 0.2 4.6 2.0 19.4 Japan 0.0 0.1 0.1 0.6 1.7 4.5 Japan 0.1 0.9 4.2 18.1 8.2 35.3 Korea, Rep, 6.1 6.7 4.7 5.8 8.3 41.0 Korea, Rep, n.a. n.a. n.a. n.a. 0.1 1.6 New Zealand 2.7 3.6 3.3 4.4 2.4 3.8 New Zealand 15.5 34.0 12.7 31.7 16.1 56.5 Norway 0.0 0.0 0.0 0.0 1.0 10.6 Norway n.a. n.a. 0.0 0.1 3.6 23.0 Singapore 0.0 0.0 0.0 0.0 0.0 0.0 Singapore 12.9 25.2 34.9 91.7 19.8 65.2 Switzerland 0.0 0.2 0.0 0.2 0.1 0.9 Switzerland 1.8 9.2 3.2 18.6 2.4 12.1 United States 0.6 1.3 1.7 3.2 2.7 8.0 United States 1.6 15.8 7.8 55.4 10.3 40.4 Average Davos country 1.3 1.8 2.2 3.4 2.6 7.7 Average Davos country 5.2 14.8 9.3 35.7 7.3 31.0 Income group (number Income group (number of countries) of countries) HIC (18) 2.2 3.1 2.9 3.8 3.7 15.8 HIC (14) 5.8 16.1 6.9 29.1 7.0 30.4 UMIC (29) 4.5 6.2 8.9 12.5 8.0 12.9 UMIC (23) 13.8 25.2 18.6 41.9 17.0 42.7 LMIC (27) 3.7 4.9 7.5 10.3 7.8 14.6 LMIC (23) 30.2 52.2 23.9 40.7 19.6 44.8 LIC (21) 5.2 6.6 12.8 15.4 13.4 19.2 LIC (10) 40.5 70.2 16.7 33.1 10.7 25.6 11 Source: Authors’ calculations from TRAINS (2013), BACI (2013), Kee et al. (2008, 2009) and WDI (2013) data. APEC list has 54 products and WTO list has 411 products. Income groups are simple average values. Applied MFN tariffs and imports are mean values for 2010-11. Estimates for “other goods” using the WTO list are not reported as they follow a similar pattern than with the APEC list of 54 products. Trade data is missing for Chinese Taipei in the BACI database hence the Davos group list is reduced to 13 countries. Furthermore, as data on NTBs are scarce for many countries, individual Davos countries figures displayed in columns 7 to 10 must be considered with extreme caution as the lines with missing NTB estimates are eliminated from the estimates in col. 9. For example, China only has NTB data for 5 products on the APEC list so the average estimate in column is over 5 products, which explains why that total protection estimate in column 7 is lower than the tariff estimate in column 1. Notes: The groups are (abbreviation and 2011 GNI per capita, yp, cut-offs in $ in parenthesis): high-income (HIC, yp>12,476$), upper-middle Income (UMIC yp>4,036$ and <12,475$), lower-middle income (LMIC, yp>1,026$ and <4,035$,) and low-income countries (LIC, yp<1,025$). To reduce the weight of extreme elasticity estimates, for each income group estimates outside the 1st and 9th deciles were fixed at the respective decile cut- offs. The TRI is the uniform tariff that, if applied to imports instead of the current structure of protection, would leave welfare at its current level. Melo and Vijil (2014) also report estimates of the uniform tariff (the OTRI) that, if applied on home imports instead of the current structure of protection, would leave aggregate imports at their current level. The formula captures the fact that the welfare costs of tariffs rises more than proportionately with the tariff and that it is positively related to the variance in tariffs. The formula for the TRI for country c is: 1  ∑ n mn ,cε n ,cTn2,c  2 TRI c =  =  ; Tn ,c (mfnn ,c ; mfnn ,c + ntbn ,c ) ;  ∑ mn ,cε n ,c   n  mfnn ,c = applied MFN tariffs and ntbn ,c = ad-valorem equivalent of NTBs from Kee et al. (2009), for product n at the HS 6-digit level in country c; mn ,c = import value (thousand US$) and ε n ,c = price import demand elasticities for product n in country c taken from Kee et al. (2008). 12 Third, Melo and Vijil (2014) report the difference between consolidated tariffs and applied MFN tariffs or “binding overhang”, a margin of flexibility (“policy space”) for governments. This flexibility is greatest for middle income countries, and practically non-existent for HICs. So if there were a standstill compromise, whereby tariffs would be bound at applied rather than bound rates, the UMIC and LMIC groups would lose the most leeway as the current gap of 16 and 14 percentage points would have to be closed (using the WTO list). For the LIC group, the gap is 3 percentage points, so average applied tariffs would have to be reduced from their current level of 15% to 12% (HIC would only have to reduce their average tariffs by 2 percentage points to 2%). Fourth, an examination of the profile of tariffs for EGs vs. non-EGs over the Doha negotiation period (Melo and Vijil, 2014; figure 1) shows no acceleration in the reduction of tariffs on EGs (or on non-EGs) and the trends were almost the same for EGs and for other products suggesting no evidence that the environment was taken on board at the country-level during the negotiations. 9 Finally, the right-hand side of table 1 gives average estimates of overall ‘protection’ taking into account non-tariff barriers. These are, at best, indicative. First, unlike tariffs, not all NTBs are welfare-reducing as some are correcting for market failures. Second, estimates are for a smaller group of 70 countries at the HS-6 commodity level for 2010-11. Third, the Ad- Valorem Equivalents (AVEs) of NTBs are obtained from NTBs represented by binary variables for 2003-4 with a small number of AVEs for some countries. Adding these AVEs to the tariff estimates for 2010-11 gives the estimate of the combined measures of protection in columns 7 to 10. 10 Except for the HIC, the resulting overall ‘protection’ estimates for the APEC list reported in col. 7 are high or very high. The estimates preserve the rank-ordering for tariffs: highest for the LIC, followed by LMIC, UMIC and HIC. 3.2 Tariff and non-tariff barriers protection of the Davos group of countries We now compare the protection indicators for the Davos group of 14 countries (there are only 13 here as trade data for Chinese Taipei are missing) with the averages by income group. Several patterns stand out. Among those who pledged to reduce tariffs, six countries have zero tariffs (see also table 3 for simple average tariffs). Unless NTBs are included in the negotiations—or the list is expanded in the case of Costa Rica— these countries will have nothing to ‘offer’ at the table of negotiations. 9 Using a slightly different data set over the period 1996-2010, Balineau and Melo (2011) examined cases of ‘substantial tariff reductions’ in EGs defined as tariff reductions of 5 percentage points or more. They found that two thirds of the countries had at least one substantial tariff reduction or ‘event’ during 1996-2010 defined as a tariff reduction of at least 5 percentage points. Each product in the core list of 26 products accounted for about 4%-5% of the total number of events. 10 The NTB measures exclude price support measures. For reasons discussed in Melo and Vijil, the average estimates in Table 1 could represent lower bound estimates of the actual level of protection. However, unlike tariffs, not all NTBs are welfare-reducing since some provide regulations to correct market failures. 13 This lack of substance to negotiate on is reflected in average tariffs of 1.3% for the Davos group. Only four countries have average tariffs above 1% on the APEC list and among the OECD countries only the Republic of Korea and New Zealand would have significant reductions to carry out if tariffs were to be eliminated. Using the TRI measure of protection which gives the average uniform tariff that would give the same welfare loss as the current structure with dispersion, at most (for the WTO list), the tariff protection for the group is equivalent to a uniform tariff of 3.4%, hardly a high estimate. What about expanding the list along the lines suggested in the Davos communiqué (“APEC [list] has given us a good start, and we are committed to exploring a broad range of additional products”)? As can be seen from column 3, average reductions would be greater in the expanded list because countries have omitted from their submission lists products with tariff peaks. Yet, average protection is only 2.2%, equivalent to a uniform tariff of 3.4%. On the other hand, expanding the list of countries while keeping the APEC list would probably encounter greater resistance since, with the exception of China which has a higher protection than the average for the UMIC group, the Davos countries are the countries with low average protection in EGs in their respective income group. Second, China and Korea stand out with average tariffs at least twice as high as for others. Comparing EGs tariffs for the Davos participants with the averages for their income category, China, Korea and New-Zealand have above-average tariffs. Korea would probably be interested in pushing for an extension towards the WTO list, as average tariffs on that list are lower than on the APEC list. The disparity between China and Korea and the rest of the Davos members hints at a possible scenario in which these two countries might insist on a less than full elimination of tariffs, say a 50% cut across the board. Third, even though the country-level tariff-equivalent estimates of NTBs are dated, incomplete (see notes in table 1), and difficult to interpret in terms of welfare, the values are generally high, although they are close to the averages for their respective groups discussed earlier. In conclusion, since there are very few tariff peaks in the Davos group (see Annex, Table 3), as it now stands, the Davos initiative will do little to help moving towards global free-trade. 3.3 Import response estimates to a lowering of trade barriers Even though the Davos group accounts for 74% percent of trade (intra-EU trade excluded) in EGs using the APEC list, increased country participation is essential to reach free-trade in green goods. So far, all but HIC countries have been adamant to submit lists of goods for tariff-reduction negotiations. This is because of a fear of being inundated by imports from industrialized countries. Taking the same format as table 1, table 2 gives first-order estimates of import response to a 50% and total reduction in tariffs for individual Davos 14 countries and averages across country groupings. The import response for each product depends on the height of the tariff at the HS6-level and on the corresponding price elasticity for that product. Price elasticity estimates are from Kee et al. (2008). The price elasticity estimates are applied to average import data for 2010-11 at the HS 6-digit level and the reduction in protection is carried out only for tariffs on the APEC list (and also on the WTO list for the classifications by income group). Estimates for each Davos country are obtained by adding up estimates at the product level. For those at the region level, to save space, only group averages are reported. 11 Because the import response is the result of applying the price elasticity estimate to the tariff rate, one could obtain low import response for a country (group of countries) with high tariffs if the corresponding price elasticity is low. Despite substantial differences in prices elasticities across country groupings, with higher average price elasticity estimates for high- income countries (as one would expect, since substitutes to imports are higher for low- protection HIC group), the estimates show a monotonic relation between average protection and import response. Taking the WTO list where disparities in protection are greatest across groups, the LIC group with the highest average protection (8.9%) shows the highest average import response (7.9%) to a cut in half of tariffs. This estimate is however barely greater than the one for the UMIC group, whose average protection rate is 30 percent lower than the one of the LIC group. The estimated magnitudes are small. An average increase in imports ranges between 2-4 percent for a 50% reduction on the APEC list and between 2-8 percent for the WTO list; estimates that are far from hinting at a possible import surge. For the Davos group, only China, Korea, and New-Zealand could expect import increases in the 7-10 % range in an ambitious scenario where tariffs are completely eliminated. However these estimates do not account for any supply response that would entail a reduction in output and employment requiring adjustment assistance. Still, the estimates are obtained by applying the MFN tariffs on all imports while imports under free-trade agreements should have been omitted from the estimates. 11 The discussion paper version gives the formula for calculating the estimates and figure 2 reports the distribution of elasticities by income group. 15 Table 2: Simulated import responses to a reduction in trade barriers (tariffs only) Applied 50 % 100 % MFN Green goods lists by Tariff Initial Add.

Environmental projects have a great degree of ‘jointness’ or complementarity between the services provided by EGs and those provided by ESs. This is especially the case in developing 16 countries for which case studies show that the ESs included in environmental projects incorporate an increasingly large array of services that extend beyond those that are classified as ESs (OECD, 2005). Hence, as in figure 1b, it is necessary to go beyond the standard UN CPC definition of ESs to get an approximation of the ESs that are most intensively used in environmental projects. The challenge is to measure the restrictiveness of trade in Environmental Services. Recent estimates of trade costs in services suggest that they are higher than for trade in goods. Solving a gravity model from trade to obtain trade costs as suggested by Novy (2012), Miroudot et al. (2013) report estimates of trade costs for mode I (cross-border services trade) and mode II (movement of consumers) services for 55 countries over the period 1999-2009. They conclude from their estimates that trade costs in services could be two to three times higher than those for trade in goods (estimated using the same method). As many countries did not participate in the GATS, the authors also investigate whether RTAs have resulted in a reduction in trade costs. Using a services liberalization index measuring the commitments to national treatment and market access, they estimate only a small reduction in trade costs for services via RTAs, confirming the often-made remark that commitments at the GATS—for those countries that made commitments (since countries were not obliged to table any offer)—just consolidated 12 members’ existing domestic regulation regarding services. 12 Using the same database to estimate trade costs in 66 bilateral RTAs, Miroudot and Shepherd (2013) find that RTAs reduced bilateral trade costs, but that these reductions in trade costs largely benefit non-members as well. In other words, any liberalization in the services sector (for modes 1 and 2) through an RTA is tantamount to a multilateral liberalization. However, they acknowledge that lack of data on mode 4, for which the scope for discrimination is greater, results in an incomplete picture. 17 Figure 1: GATS score commitments for environmental services and other services 1a. ES: narrow definition 1b. ES: wide definition Environamental services Other services Environamental services Other services HIC (15) HIC (15) UMIC (12) UMIC (12) LMIC (10) LMIC (10) 0 20 40 60 80 0 20 40 60 80 Score (min=20; max=100) Score (min=20; max=100) Source: Melo and Vijil (2014; figure 3). There are no available data for LIC in the service commitments database. The narrow definition only considers ES as defined by the W/120 list; the wide definition adds to these ES the following W/120 sectors: professional services, research and development services, other business services, and construction and related engineering services. The qualitative ESL index covers all 4 services modes. It aggregates two indexes, one for commitments to national treatment, another for commitment to market access (see Melo and Vijil 2014; annexes 1 and 2 for the derivation and choice of weights) In Melo and Vijil (2014) we construct a similar Environmental Services Liberalization (ESL) index to check if there is any difference in commitments for ESs vs. other services. Figure 1 confirms greater commitments for high-income countries and slightly higher commitments for Environmental Services than for the rest. However, the informational value of the index is limited because actions to improve the environmental use of services go beyond those categorized as ES in the CPC, which are the only services considered as belonging in the ES category. 13 It is likely that negotiations on ESs will also be off the Davos agenda, as negotiators will hold off taking them on board, pending the outcome of the Trade in Services Agreement (TiSA) negotiations. Should this agreement result in participants exchanging the best commitments they have so far undertaken in their PTAs (Marchetti and Roy, 2013), ESs could be substantially liberalized, as most of the opening has occurred on a North-South preferential basis. Because complementarities between trade in EGs and trade in ESs are especially 13 In Melo and Vijil (2014), we used ESL indexes to suggest that liberalization in ESs might go further through North-South RTAs than multilaterally. This might be expected as most of the world market, particularly for infrastructure ES, is in the hands of firms from HIC that have strong interests in prying open developing countries’ domestic markets (Kirkpatrick, 2006). These patterns suggest that developing countries are only likely to continue liberalizing trade in ESs as part of RTAs. Similarities in commitments across modes might be sufficiently high to allow these liberalization steps to be multilateralized, especially if the Davos-led negotiations gather momentum. Moreover, as rules of origins are difficult to impose on services trade, RTA commitments could be extended on a multilateral basis. 18 strong in low-income countries, they are likely to lose the most if the agenda is not extended to tackle NTBs and ESs. Should ESs be on the agenda, negotiators are likely to stumble when it comes to agreeing on a more appropriate list than the current UN CPC. Even with a more appropriate list of ESs, because it is far harder to monitor the fulfillment of commitments to liberalization, disincentives to negotiate on services will be strong, especially when negotiating partners lack trust in each other. Reflecting on the lack of success with liberalization of services, Messerlin (2013) argues that ‘mutual equivalence’ rather than mutual recognition or harmonization is the better way to go and that this route-- which was followed by the EU Services Directive--might be best implemented on a regional basis where the trust necessary to agree on the regulations to be covered by mutual agreement is more likely. 5 Conclusions The announcement made in Davos by 14 members to re-launch negotiations on environmental goods liberalization has given new hope that the WTO is not dead. Plurilateral agreements extended to all WTO partners on an MFN basis have been pointed out as a multilateral-friendly solution to continue liberalization while Doha negotiations linger on. It is expected that talks will first focus on goods starting with the APEC list of 54 green goods that will be further extended, but the WTO members behind the initiative hope to create a “living agreement” that will grow and evolve towards tackling other barriers to trade in green goods and services. Indeed, today non-tariff barriers are relatively more important than tariffs and there is a high complementarity between green goods and services at the project level. Looking at tariff and non-tariff barriers to trade in environmental goods and services through the lens of all countries and with a special focus on Davos partners, we find that the Davos initiative, as it stands, will only help little for moving towards global free-trade. However, this perspective could change if at least one (and preferably all) of the following options are considered; (i) a complete elimination of all tariffs for all countries as they are already low; (ii) an extension of the list of environmental goods in line with the WTO list of 411 products, even though few tariff peaks remain on these goods; (iii) the participation of an increased number of countries, particularly middle-income countries, since a substantial reduction in tariffs would not be followed by an inundation of imports; (iv) tackling non-tariff barriers, recognizing that an agreement on their identification will be difficult, and finally and importantly; (v) the liberalization of environmental services with a degree of commitment close to the best regional agreement. 19 References Balineau, G., and J de Melo (2011) “Stalemate at the Negotiations on Environmental Goods and Services at the Doha Round”, WP #28, FERDI Balineau, G., and J de Melo (2013) “Removing Barriers to Trade on Environmental Goods: An Appraisal”, World Trade Review, 12(4), 693-718.

Each member was to identify EGs within its national tariff lines at the 8-digit, 10-digit or higher using guidelines in Annex C of the APEC declaration, as only these tariff lines were required to benefit from tariff reductions. In principle, negotiations under the Davos initiative will take place at the HS-6- 2012 classification. To get a more accurate estimate of tariff peaks, it is useful to see the number of tariff lines at the national level with tariff peaks. These are given in columns 5 and 6 in table 3. Table 3.
