REVISED NEW ZEALAND PROVISIONAL LIST OF ENVIRONMENTAL GOODS 
 
Submission by New Zealand  
 
Paragraph 31 (iii)  
 
Revision  
  
 The following communication, dated 11 October 2005, is being circulated at the request of 
the Delegation of New Zealand
. 
 
_______________ 
 
  
1. New Zealand welcomes the intensification of th e negotiations pursuant to paragraph 31(iii) of 
the Doha Ministerial Declaration on environmental goods.  With a view to moving the discussion 
forward, this submission contains a further el aboration of New Zealand’s provisional list of 
environmental goods, providing additio nal information on the environmental benefits of the products 
proposed.   
2. New Zealand’s provisional list of envir onmental goods was fi rst submitted to the 
Committee on Trade and Environment in Special Session (CTESS) on 26 May 2005.  In that 
submission (TN/TE/W/49), New Zealand outlined its ‘d efining by doing’ approach to preparing its 
list of environmental goods.  ‘Reference points’1 were used to provide a screening mechanism to 
ensure nominated products met a basic threshold.  Goods were organised into categories, to provide 
an indication of their environmental credentia ls.  The submission also noted the importance 
New Zealand attached to a ‘living list’.  This woul d ensure that any agreed WTO list of environmental 
goods would be able to reflect the dynamic nature of new technologies, given the continual evolution 
of the environmental industry.2 
3. From the discussion of its list at the twelfth and thirteenth meetings of the CTESS 
(7-8 July and 15-16 September 2005), New Zealand h as noted the desire of other Members to better 
understand the rationale for New Zealand’s nominat ion of certain products as environmental goods.  
In order to supplement the reference points and cat egories already provided, New Zealand has further 
revised its list to include a new ‘Environmental Benef its’ column.  This contains brief explanations of 
the environmental applications and advantages of each product on New Zealand’s environmental 
goods list.  It is hoped that the information provid ed in the new column w ill assist Members in the 
                                                      
1 In TN/TE/W/46 of 10 February 2005, New Zealand proposed the 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. 
2 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).  TN/TE/W/49/Rev.1 
Page 2  
 
more technical discussions of cate gories and particular products whic h are now needed to explore the 
trade and environment ‘win-win’ potential of the list approach to the environmental goods 
negotiation.       
4. New Zealand also considers that there is a th ird ‘win’ for development to be achieved from 
the Paragraph 31(iii) negotiation.  It is recalled that  New Zealand’s statement to the informal meeting 
of the CTESS on 10 June 2005 (TN/TE/W/49/Suppl.1) outlined many of the developmental benefits 
that could be achieved as a consequence of the lib eralisation of trade in environmental goods.    
5. The revised New Zealand provisional environm ental goods list also includes a second new 
column correlating each product on the list to the entr ies in Annex II of the Informal Note by the 
WTO Secretariat's "Synthesis of Submissions on Environmental Goods" (JOB(05)/57/Rev.2), for ease 
of reference to that document.   
6. New Zealand reserves the right to add to or dele te items on the attached list or to amend these 
as appropriate during the negotiation process.      TN/TE/W/49/Rev.1
