In pursuit of sustainable development and taking into account its obligations under those international agreements concerning the environment to which it is party, each Contracting Party shall strive to minimise in an economically efficient manner harmful Environmental Impacts occurring either within or outside its Area from all operations within the Energy Cycle in its Area, taking proper account of safety. In doing so each Contracting Party shall act in a Cost-Effective manner. In its policies and actions each Contracting Party shall strive to take precautionary measures to prevent or minimise environmental degradation. The Contracting Parties agree that the polluter in the Areas of Contracting Parties, should, in principle, bear the cost of pollution, including transboundary pollution, with due regard to the public interest and without distorting Investment in the Energy Cycle or international trade. Contracting Parties shall accordingly:

• (a) take account of environmental considerations throughout the formulation and implementation of their energy policies;
• (b) promote market-oriented price formation and a fuller reflection of environmental costs and benefits throughout the Energy Cycle;
• (c) having regard to Article 34(4), encourage cooperation in the attainment of the environmental objectives of the Charter and cooperation in the field of international environmental standards for the Energy Cycle, taking into account differences in adverse effects and abatement costs between Contracting Parties;
• (d) have particular regard to Improving Energy Efficiency, to developing and using renewable energy sources, to promoting the use of cleaner fuels and to employing technologies and technological means that reduce pollution;
• (e) promote the collection and sharing among Contracting Parties of information on environmentally sound and economically efficient energy policies and Cost-Effective practices and technologies;
• (f) promote public awareness of the Environmental Impacts of energy systems, of the scope for the prevention or abatement of their adverse Environmental Impacts, and of the costs associated with various prevention or abatement measures;
• (g) promote and cooperate in the research, development and application of energy efficient and environmentally sound technologies, practices and processes which will minimise harmful Environmental Impacts of all aspects of the Energy Cycle in an economically efficient manner;
• (h) encourage favourable conditions for the transfer and dissemination of such technologies consistent with the adequate and effective protection of Intellectual Property rights;
• (i) promote the transparent assessment at an early stage and prior to decision, and subsequent monitoring, of Environmental Impacts of environmentally significant energy investment projects;
• (j) promote international awareness and information exchange on Contracting Parties’ relevant environmental programmes and standards and on the implementation of those programmes and standards;
• (k) participate, upon request, and within their available resources, in the development and implementation of appropriate environmental programmes in the Contracting Parties.
