Where they have authority, nations shall assess the environmental impact of proposed activities that are likely to have a significant adverse impact. Nations should cooperate to promote an open international economic system that will lead to economic growth and sustainable development in all countries. Environmental policies should not be used as an unjustifiable means of restricting international trade. The polluter should, in principle, bear the cost of pollution. Nations shall warn one another of natural disasters or activities that may have harmful transboundary impacts.
Sustainable development requires better scientific understanding of the problems.
Nations should share knowledge and innovative technologies to achieve the goal of sustainability. The full participation of women is essential to achieve sustainable development. The creativity, ideals and courage of youth and the knowledge of indigenous people are needed too. Nations should recognize and support the identity, culture and interests of indigenous people. Warfare is inherently destructive of sustainable development, and Nations shall respect international laws protecting environment in times of armed conflict, and shall cooperate in their further establishment.
