Que signifie l'avis consultatif de la Cour internationale de Justice sur le changement climatique pour les évaluations d'impact environnemental ?

This briefing by the International Institute for Sustainable Development examines the implications of an International Court of Justice (ICJ) advisory opinion on climate change, specifically regarding the requirement to include downstream emissions from fossil fuel combustion in Environmental Impact Assessments (EIAs).

• The International Court of Justice (ICJ) has ruled that Environmental Impact Assessments (EIAs) must account for downstream emissions resulting from the combustion of extracted fossil fuels. This ruling aligns with previous decisions from the EFTA Court and the UK Supreme Court.
• Within six months of the ICJ verdict, at least two national and regional court judgments have applied this ruling to the requirement for calculating anticipated downstream emissions for new oil fields. To mitigate legal risks, states are advised to update laws, regulations, and guidelines to ensure all indirect and Scope 3 emissions are included.
• The document provides three specific recommendations for states modifying their EIA rules: first, the decision to assess downstream emissions should not be influenced by the argument that market demand would be met by another project if the current one were not realized; second, it should be presumed that all produced fossil fuels will be combusted to prevent unsupported claims by industry; and third, downstream emissions should be evaluated cumulatively in a global context and against national and global climate goals.
