As called for in the Doha Ministerial Declaration, Members of the World Trade Organization (WTO) have initiated negotiations on “the reduction or, as appropriate, elimination of tariff and non-tariff barriers to environmental goods and services.” The liberalization of trade in environmental goods and services (EGS) may bring economic, environmental and developmental benefits to developing countries through easier access to environmentally sound technology, as well as improved resource management and environmental conditions.
Comme demandé dans la Déclaration ministérielle de Doha, les membres de l'Organisation mondiale du commerce (OMC) ont engagé des négociations sur «la réduction ou, selon qu'il sera approprié, l'élimination des obstacles tarifaires et non tarifaires visant les biens et services environnementaux».
