MARKET ACCESS FOR ENVIRONMENTAL GOODS:  
REVISED NEW ZEALAND LIST 
 
Submission by New Zealand  
 
Paragraph 31 (iii)  
 
Revision  
 
 
I. INTRODUCTION 
1. New Zealand welcomes the further intensif ication of the negotiations pursuant to 
Paragraph 31(iii) of the Doha Ministerial Declarati on on environmental goods.  With a view to further 
contributing to this intensificati on, this submission contains a re vision of New Zealand’s provisional 
list of environmental goods.  
II. THE NEW ZEALAND LIST OF ENVIRONMENTAL GOODS 
2. New Zealand’s provisional list of environmen tal goods was first submitted to the Committee 
on Trade and Environment in Special Session (CTESS) on 26 May 20051.  In that submission, 
New Zealand recalled its approach to the environm ental goods negotiations und er paragraph 31 (iii).  
In particular it was noted that  New Zealand had earlier proposed2 that rather than focus on definitional 
issues, the Committee proceed in these negotiations  by ‘defining by doing’ through the use of 
“reference points.”3 In this way, the CTESS would be able  to establish the precise scope of the 
negotiations by identifying particular products  which Members might consider “environmental 
goods.” In this submission, New Zealand also introduced the concept of a “living list.” 
Implementation of this part of the New Zealand pr oposal would ensure that any agreed WTO list of 
environmental goods could take into account the dynamic nature of new technologies, given the 
continual evolution of th e environmental industry.4 The concept has been supported by other 
Members5 and New Zealand expects to table an elaboration of its ‘living list’ proposal shortly.  
3. The approach of “defining by doing” was implemented through the development of the 
New Zealand list of environmental goods. This utilised the concept of “reference points” which acted

 2 TN/TE/W/46 of 10 February 2005 refers. 
 3 In TN/TE/W/46 (ibid), New Zealand proposed th e following three reference points: the OECD’s 
definition of environmental industries; APEC’s conceptualisation of environmental goods; and approaches to environmental goods agreed through high quality and comprehensive regional or bilateral Free Trade 
Agreements. 
 
4 The OECD has estimated that half of the environmental goods likely to be in use within the coming 
decade do not currently  exist (OECD (1998) The Global Environmental Goods and Services Industr y, OECD 
Publications, Paris).

  as a type of screening mechanism to ensure nomina ted products met a basic threshold.  In addition, 
the products New Zealand proposed for the negotiations  were further organised into categories. This 
was designed to assist the negotiations by providi ng an indication of the environmental purposes for 
which these products might be used. In its developm ent of its list, New Zealand identified five new 
categories in addition to those proposed to date
6. These were wastewater management; natural risk 
management; environmentally preferable products based on end-use or disposal characteristics7; 
cleaner or more resource-efficient technologies and products; and waste and scrap utilization 
products. 
4. Members have had numerous opportunities to  comment on the New Zealand list of 
environmental goods, including at the twelfth and th irteenth meetings of the CTESS (7-8 July and 
15-16 September 2005). In addition to these meetings, New Zealand engaged in a series of bilateral 
meetings to discuss, inter alia, its list of envi ronmental goods. A number of Members sought more 
specific information from New Zeal and so that they could better understand the rationale for its 
nomination of certain items as environmental goods. 
5. It was against the background of the twelfth a nd thirteenth meetings of the CTESS that New 
Zealand provided further information about its list of environmental goods. In order to supplement the 
reference points and categories already utilised , New Zealand introduced a new ‘Environmental 
Benefits’ column to its list of products.8  This provided succinct explan ations of the environmental 
applications and advantages of all of the products on New Zealand’s environmental goods list.  This 
information was designed to assist Members in the more technical discussions of categories. It also sought to assist Members wanting to consider the trade and environment ‘win-win’ potential of the 
products proposed for the environmental goods ne gotiation. The revised New Zealand submission 
also included a second new column correlating each pr oduct on its list to the entries contained in 
Annex II of the WTO Secretariat's "Synthesis of Submissions on Environmental Goods". This was 
designed to assist in cross-referencing the Ne w Zealand list with the Secretariat’s document.
9 
6. Like many other Members, New Zealand considers that there is a third ‘win’ in these 
negotiations which supplements the dual ‘wins’ on e nvironment and trade. This is the potential that 
the negotiations under paragra ph 31(iii) have to contribute to  substantive international 
development-related outcomes.  It is  recalled in this regard that Ne w Zealand has formally outlined in 
some detail the numerous developmenta l benefits that it considers can be secured as a consequence of 
the liberalisation of trade in environmental goods.10  
7. On 12 October and on 1 November 2005, subs tantive information exchange sessions were 
held to discuss the products which Members had proposed for the negotiations on environmental 
goods. This provided a useful opportunity for Members, including New Zealand, to explain the trade, environmental and development benefits of the products that have been proposed to date.  
                                                     
 
 6 In JOB(04)/98, 16 July 2004, Canada proposed the following categories for consideration:  air 
pollution control;  water pollution control;  solid/hazardous waste management; remediation/clean-up of soil and 
water;  noise/vibration abatement;  environmental monitoring, analysis and assessment equipment;  potable 
water treatment;  recycling systems;  renewable energy plant;  heat/energy management;  and soil conservation.   
7 The concept of environmentally preferable products draws on asp ects of the work undertaken by 
UNCTAD (UNCTAD (1995) Environmental Preferable Products (EPPs) as a Trade Opportunity for 
Developing Countries,  Geneva, UNCTAD (UNCTAD/COM70).  It is important to note that New Zealand 
considers that the EPP concept be utilised only when the product to which it refers can be identified by end-use 
or disposal characteristics.

  8. At these two information exchange sessions, the linkages between environmental goods and 
environmental services were explored. New Zealand, for instance, referred to a range of current and 
forthcoming studies that underline the close re lationship between environmental goods and 
environmental services.11  New Zealand also reported in some  detail on the linkages it considered 
existed between the delivery of environmental services related to the items it had proposed. 
New Zealand made specific reference to environm ental services related to wastewater management 
products, environmentally preferable products defined by end-use, produc ts that can assist in natural 
risk management and soil and water remediation and clean-up products. It was also noted by many 
Members that the linkages between the negotiations in the CTESS and those underway in the Special 
Session of the Committee on Trade in Services shoul d be borne in mind during the negotiations on 
environmental goods. In this regard, New Zealand fu rther recalled a report by the Chair of the CTESS 
to the Trade Negotiations Committee. This confir med that there was broad support in the CTESS for 
the view that the negotiations on environmental se rvices be conducted as part of the overall services 
negotiations in the Special Session of the Council for Trade in Services.12 Moreover, New Zealand is 
also a co-sponsor of a plurilateral request on enviro nmental services which is being pursued as part of 
the complementary approaches to the services market access negotiations, as mandated by the 
Hong Kong Ministerial Declaration.13 
9. At both of the information exchanges in 2005, New Zealand also took the opportunity to note 
that it stood ready to engage on the range of cross- cutting issues identified in paragraph 31(iii) of the 
Doha Declaration. Indeed, some of the products on  the New Zealand list were being provided through 
a form of technology transfer to developing countries,  particularly in the South Pacific region, with a 
particular emphasis on wastewater management products, monitoring and assessment equipment and 
soil and water remediation and clean-up items. 
10. In terms of the issue of non-tariff barriers, Ne w Zealand like other Members regarded this as a 
similarly serious issue. It proposed that discussi on move from the abstract and conceptual to the 
practical and New Zealand looked forward to the identification of specific non-tariff barriers that 
affected Members’ market access for environmental goods.  
11. At the information exchange sessions and sub sequently, New Zealand took the opportunity to 
note that it saw scope to ensure that special and differential treatment issues be addressed. This 
particular issue has been taken up in a specific proposal on modalities that New Zealand co-sponsored.
14  
III. THE POST-HONG-KONG MINISTERIAL PROCESS 
12. At the Ministerial meeting in Hong Kong, Ministers instructed officials to intensify the 
negotiations and to complete the work expeditiously un der paragraph 31(iii)15. This provided the 
context for the CTESS meeting on 21-22 February, 2006 at which Members explored the range of 
possible parameters which might be used to inform  the negotiations. This in turn provided the basis 
for three further technical discussions on environmental goods. These took place on 4-5 April, 
10-12 May and 12-13 June. Each meeting consider ed specific categories of environmental goods.

  13. The first technical discussion on environmenta l goods provided an opportunity to exchange 
technical information about the categories of Air Pollution Control and Renewable/Clean Energy. The second focused on the Wastewater Management and Solid and Hazardous Waste Management categories. The third technical exchange considered the remaining categories proposed by Members. This encompassed the range of products that were contained in the categories of Environmental 
Monitoring, Analysis and Assessment Equipment; Remediation and Clean-Up of Soil and Water; 
Cleaner Technology and Products;  Environmentally Preferable Products Based on End-Use or Disposal Characteristics; Products with High E nvironmental Performance or Low Environmental 
Impacts; Others (Noise and Vibration Abatem ent; Resource Management; Heat and Energy 
Management; Natural Risk Manage ment; Potable Water Treatment; Recycling Systems; and Soil 
Conservation).   
14. New Zealand was an active participant at all three technical sessions. At the first technical 
session at which Renewable/Clean Energy and Air Pollution Control produc ts were considered, 
New Zealand registered its view that a focus on single-end use products would fail to meet the 
mandate of the negotiations to contribute to th e environment and development objectives Ministers 
had established at Doha, Qatar in 2001.   
15. New Zealand co-sponsored a paper with a number of other Members that was designed to 
facilitate the exchanges at the second technical session on 10-12 May.
16 This meeting was focused on 
products proposed for the categories of Waste Wa ter Management and Solid  and Hazardous Waste 
Management. The paper responded to the Chair’s re quest to provide "detailed explanations on the 
environmental and developmental aspects of products that have been identified under the two new 
categories"17 of waste water management and solid and hazardous waste products. It elaborated in 
detail on both of these aspects and noted how im proved access for environmental goods would help 
Members achieve improved environm ent and development outcomes. It also provided a definition of 
the two categories18 under discussion and outlined the range  of approaches taken on dual and 
multi-use items.  
16. New Zealand found the exchanges at the sec ond technical session helpful in terms of 
informing its own thinking on some of the items it had proposed for the negotiations. In particular, 
New Zealand took careful note of the range of pers pectives expressed regard ing the waste and scrap 
utilization category it had identified. Additionally, comments regarding some of the chemicals which 
New Zealand had identified as havi ng environmental benefits were also taken into account in the 
context of New Zealand’s ongoing work to review its list of environmental goods. 
17. The third technical exchange session considered the remaining categories proposed by 
Members. These were Environmental Monitoring, Analysis and Assessment Equipment; Remediation 
and Clean-Up of Soil and Water; Cleaner Technolog y and Products;  Environmentally Preferable 
Products Based on End-Use or Disposal Charact eristics; Products with High Environmental 
Performance or Low Environmental Impacts; Others (Noise and Vibration Abatement; Resource 
Management; Heat and Energy Ma nagement; Natural Risk Manage ment; Potable Water Treatment; 
Recycling Systems; and Soil Conservation).  
18. New Zealand presented a submission on the category of Remediation and Clean-Up of Soil 
and Water to the third technical exchange session.19 This responded to the Chair of the CTESS’ 
request that Members who had proposed products for the negotiation “provide as far as possible a

  description of the environmental, trade and devel opmental benefits of the products/systems in 
question.”20  The New Zealand submission elaborated on these aspects. It noted how improved market 
access for products that assist in the remediation and clean-up of soil and water will contribute to achieving improved environment, tr ade and development outcomes. Th e paper also responded to the 
Chair’s request that contributions to the techni cal discussion “indicate products/systems of single 
environmental-end use”.  The annex to the paper ou tlined all of the items proposed to date by the 
Membership in the category of Remedia tion and Clean-Up of Soil and Water. 
IV. DEALING WITH DUAL-USE ITEMS 
19. At the second and third technical exchange session, the issue of how to address dual and 
multiple-use-related issues was di scussed at some length. New Zealand’s submission21 observed that 
this is a particular (though by no means unique22) challenge for these negotiations. It was suggested 
that in order to effectively address the issu es thrown up by dual and multiple-use products, a 
pragmatic approach should be adopted. This needed to take into account the broader commitment of 
Members to “maintain the process of reform and libera lisation of trade policies, thus ensuring that the 
system plays its full part in promoting recovery, growth and development”23. A number of Members, 
including New Zealand observed at the technical exchange sessions that in most of the categories 
proposed for the current negotiations, there are gene rally less than a handful of products which could 
be defined according to the narrower criteri a of what some Members describe as “single 
environmental end-use items”.  It is also worth not ing that the technical exchanges clearly revealed 
that there are a range of views on how precisely th is particular criteria can be applied.  These 
contributions and the discussion at the meeting unde rlined the point therefore that this range of 
perspectives means that it may not be possible to secure a consensus on which items might readily be 
identified by the term “single environmental end-use items.” 
20. During the technical exchanges, some Member s, including New Zealand indicated that 
products with dual or multiple uses that have envir onmental benefits are an intrinsic part of the 
environmental goods negotiation.  They have a critical role to play in measuring, preventing, limiting, 
minimising or correcting environmental damage to water, air and soil as well as problems related to 
waste, noise and eco-systems.  Many environment -related activities including those discussed at all 
three technical exchange sessions simply cannot be undertaken without access to dual or multiple-use 
products.  
21. In this regard, New Zealand reported at the tec hnical exchange session that its analysis of the 
Secretariat’s Synthesis Document suggested that  with two exceptions, developing country Members 
do not have commercial interests in any of the very  small number of what some Members have in 
previous discussions described as items which ma y fall into the “single environmental end-use” 
category.  It was further noted that the main benefici aries of such an approach  were likely to be four, 
possibly five, major OECD economies and two developing country Members.
24 For these reasons, it 
was New Zealand’s view that a practical approach was required.  Dual or multiple-use items needed 
to be incorporated if the negotiations are intende d to meaningfully contribute to addressing the range 
of environmental and developm ent-related issues many Members are grappling with both 
domestically and internationally.

  22. For these reasons, New Zealand considered that many dual and multi-use products are so 
critical to securing important environment and de velopment outcomes that excluding them from the 
negotiation by applying the contested ‘single end-us e’ criterion would sharply reduce the sustainable 
development outcomes expected from this negotiati on.  New Zealand therefore considered it more 
appropriate to assess the environmental credentials of products, i.e. to consider whether the product 
has a “direct environmental benefit.”
25    
V. THE REVISION OF THE NEW ZEALAND LIST    
23. Against the background of five informal meeti ngs of the CTESS (two information exchange 
sessions and three technical exchange sessions) as well as three formal meetings since the 
New Zealand list had been first tabled, New Zealand considered it appropriate to review its list of 
environmental goods.  
24. In order to conduct its revision, New Zealand dr ew on all of the material that was discussed 
and the issues that were raised at the various mee tings (both formal and informal) of the CTESS. This 
latest revision has also been  informed by extensive domestic  consultation with a range of 
New Zealand stakeholders, encompassing the privat e and non-governmental sectors.  The outcome of 
these consultations is contained in  the annex of this document.  
25. New Zealand has made a number of significant changes to its list of environmental goods. 
In particular, the New Zealand list has been redu ced by a quarter. New Zealand has eliminated 
products from a range of categories including: Air Pollution Control; Potable Water Treatment; 
Wastewater Management; and Cleaner or More R esource Efficient Technologies. In addition, two 
entire categories have been removed completely from the New Zealand list (Scrap and Waste 
Utilisation and Natural Risk Management). All of the twenty-three entries in the Scrap and Waste 
Utilisation category have been eliminated. The five entries contained in the Natural Risk Management 
category have been reclassified. Four of these have  been absorbed into the category of Environmental 
Monitoring and Analysis Equipment and one entr y has been incorporated into the Air Pollution 
Control category.  
26. New Zealand also used the revision of its list as an opportunity to verify the 
Harmonised System (HS) descriptions it has used for its entries. New Zealand has also revised some 
of the ‘ex-out’ descriptions it had proposed. These revisions provide enhanced precision about the 
product that is being identified.  
27. It should be emphasised that the revised and re duced list is a direct and substantive response 
to the comments made by some Members during the two information exchange sessions, the three 
technical discussions and the various formal CTESS meetings at which the paragraph 31(iii) 
negotiations were addressed. These comments focused  on some of the entries contained in the 
categories of Air Pollution Control, Potable Water and Wastewater Management and Cleaner or More 
Resource Efficient Technologies. This latest revision of the New Zealand list also takes into account extensive consultations with a wide range  of stakeholders in New Zealand.  
28. At the 10-12 May technical session and the 1 November information exchange sessions, 
a number of Members asked for more informati on about the chemicals that New Zealand had 
identified in the categories of Air Pollution Contro l, Potable Water and Wastewater treatment and 
Cleaner or More Resource Efficient Technologies. New Zealand responded that these products are central to addressing environmental problems effectiv ely. Many of the items New Zealand proposed 
are, for instance, critical to ensuring water qua lity or the effective management of wastewater 
treatment processes. Moreover, the central role th ese goods play in such processes indicates that they 
                                                     
 
 25 TN/TE/W/64 of 20 February 2006 refers.  TN/TE/W/49/Rev.2 
 Page 7 
 
 
  have significant and positive developm ent-related impacts in terms of a range of international goals 
related to water and sanitation.26 It is New Zealand’s view therefore that these should be considered as 
environmental goods and be the subject of ne gotiation under paragraph 31 (iii). New Zealand 
acknowledges, however, that despite their clear role  in addressing environmental problems, the items 
proposed may not necessarily secure a consensus at this point in the negotiations. In an effort 
therefore to facilitate further rapid progress in the negotiations under paragraph 31(iii), New Zealand 
has removed all of these items from its current list of environmental goods.  
29. It is New Zealand’s view that encouraging the recycling of waste and scrap items has intrinsic 
environmental benefits. By encouraging recyc ling through improving market access for these goods, 
New Zealand believes that the negotiations woul d make a meaningful contribution to global 
sustainability. Moreover, as with the other entries that are being removed from the New Zealand list, 
it is New Zealand’s view that these reductions may limit somewhat the scope of any international development as well as environmental outco me from these negotiations. The 10-12 May 2006 
technical session in particular indicated, however , that these items may not necessarily secure the 
requisite consensus at this point in these nego tiations to be included in any agreed list of 
environmental goods. In recognition of  this, and in light of its commitment to facilitating progress in 
the negotiations, New Zealand has therefore remove d all of these entries from its current list of 
environmental goods.  
VI. CONCLUSION 
30. In sum, New Zealand has, through its revision of its list, substantively and significantly 
reduced the number of environmental goods it is proposing for these negotiations. The changes that 
have been made were undertaken with a view to  encouraging the intensification that Ministers 
directed and thus to secure rapid progress in the negotiations. While many ite ms have been removed, 
it remains New Zealand’s view that these have intr insic environment benefits. New Zealand considers 
that their inclusion would have maximized the c ontribution that the negotiations under paragraph 
31(iii) can make to global sustainability. It is ther efore regrettable that these have been eliminated 
from the current process. Nevertheless, New Zeal and believes that securing a consensus and making 
progress in these negotiations is important as a way of  demonstrating the ability of the WTO to make 
a contribution to global sustainability. New Ze aland also judged it necessary to reflect the 
considerable work that the CTESS has undertaken w ith regard to the environmental goods that have 
been proposed to date. In particular, through its s ubstantial reduction of its list, New Zealand wanted 
to acknowledge and substantivel y respond to the extensive series of comments received from 
Members during the various information exchange sessions, technical discussions, bilateral meetings, 
as well as the outcomes of the formal m eetings of the CTESS in 2005 and 2006.  
31. New Zealand’s revision and consequent reduction of its list of environmental goods has been 
made in the clear expectation that more rapid progress in the negotiations should now be possible. 
By fulfilling the mandate from Ministers establishe d in paragraph 31(iii), New Zealand believes that 
Members can make an important contribution to achieving a range of domes tic and international 
trade, environment and development objectives. Th is will reinforce the World Trade Organisation’s 
ability to contribute to global sustainable development.
