Reducing transboundary pollution

Nation states have, in accordance with the Charter of the United Nations and the principles of international law, the sovereign right to exploit their own resources pursuant to their own environmental policies, and the responsibility to ensure that activities within their jurisdiction or control do not cause damage to the environment of other states or of areas beyond the limits of national jurisdiction.

"Transboundary impact" means any significant adverse effect to a Party on one side of a border, which results from activity originating, wholly or in part, within an area under the jurisdiction of the Party on the other side of the border. Such effects on the environment include effects on human health and safety, flora, fauna, soil, air, water, climate, landscape and historical monuments or other physical structures or the interaction among these factors; they also include effects on the cultural heritage or socio-economic conditions resulting from alterations to those factors.

Article 2(6) of the Draft Protocol on Water and Health (1999) to the Convention on the Protection and Use of Transboundary Watercourses and International Lakes (1992) states: "Transboundary effects of water-related disease" means any significant adverse effects on human health, such as death, disability, illness or disorders, in an area under the jurisdiction of one Party, caused directly or indirectly by the condition, or changes in the quantity or quality, of waters in an area under the jurisdiction of another Party, whether or not such effects constitute a transboundary impact.
