Principles of International Law Relevant for Consideration in the Design and Implementation of Trade-Related Climate Measures and Policies

The report identifies and analyzes six core principles of international law—sovereignty, prevention, cooperation, non-discrimination, sustainable development/equity/CBDR-RC, and transparency/consultation—as a framework for designing trade-related climate measures. It argues that such measures are 'legal hybrids' drawing from trade, environment, and human rights law. The expert group emphasizes that these principles should be applied cumulatively and coherently to ensure a just global green transition, particularly by accounting for the different national circumstances of developing countries.

• Trade-related climate measures and policies are characterized as 'legal hybrids' because their rationale and design draw from multiple international law regimes, including those relating to the environment, climate change, international trade, general international law, human rights law, and sustainable development.
• The principle of sovereignty grants states the authority to legislate over their territory and population, but this is limited by the responsibility to ensure that activities within their jurisdiction do not cause environmental damage to other states or areas beyond national jurisdiction.
• Under WTO law, trade-related climate measures that address greenhouse gas (GHG) emissions in third countries likely possess a 'sufficient nexus' to be justifiable under GATT Article XX, because the effects of such emissions are global and adversely affect all states.
• The principle of prevention is a customary norm requiring states to exercise due diligence to prevent significant transboundary environmental harm. In the context of climate change, this involves preventing 'dangerous anthropogenic interference with the climate system'.
• To avoid being classified as 'arbitrary or unjustifiable discrimination' under the GATT Article XX chapeau, states are expected to make serious, good faith efforts to cooperate and negotiate multilateral solutions before resorting to unilateral trade-related climate measures.
• The assessment of 'likeness' between products—critical for determining non-discrimination—may evolve as consumer tastes and habits change due to increased awareness of the climate crisis, potentially allowing for different treatment of products with different carbon footprints.
• The principle of Common but Differentiated Responsibilities and Respective Capabilities (CBDR-RC) requires that climate actions reflect different national circumstances, including socio-economic conditions and historical emissions, to ensure equity.
• To avoid arbitrary discrimination under WTO law, importing members should consider the 'appropriateness' of their regulatory programs for the conditions prevailing in exporting countries, particularly for developing nations.
• Transparency in trade-related climate measures is essential for predictability and trust; it involves both 'vertical transparency' (public access to information) and 'horizontal transparency' (reporting and notification between states).
• The expert group notes a need for critical reflection on whether existing international law is 'fit for purpose', suggesting potential reforms to trade rules on subsidies, intellectual property, technology transfer, and the clarification of 'processes and production methods' (PPMs).
