In order to improve mutual support between trade and the environment, environmental goods and services were highlighted in paragraph 31(iii) of the Doha Declaration on WTO Liberalisation. By adopting the Sustainable Development Goals in 2015, our Heads of State and Government strengthened their commitment to environmental protection, including through sustainable consumption and production, sustainable management of their natural resources and urgent action against climate change. The TISA Parties` requests recognize that further liberalization of environmental services would provide increased market access opportunities, including for small and medium-sized enterprises, and improve the sustainability of health and the environment in TISA markets. Governments will only be able to choose to maintain privatized services as they are or to extend liberalization. For-profit entities have been able to pursue a so-national judicial system in order to bypass national courts.  Trade in services remains a young discipline in international trade law and the rules and degree of liberalization will continue to evolve in the coming years. . . .
