The U.S. Environmental Protection Agency (EPA) yesterday announced its intent to rescind the 2009 Endangerment and Cause or Contribute Finding for Greenhouse Gases (the Finding) later this week. The Finding, issued under the Clean Air Act (the Act) and preceded by confirmation of the EPA’s regulatory authority by the U.S. Supreme Court in a landmark 2007 decision, has served as the legal foundation for almost all climate regulations under the Act, including auto standards. Once rescinded, the EPA is expected to repeal all GHG emission standards for light-, medium-, and heavy-duty vehicles and engines. The EPA previously indicated that engine and vehicle manufacturers would no longer have any future obligations for the measurement, control, and reporting of GHG emissions for any highway engine and vehicle. The EPA has stated, however, that it would maintain regulations necessary for criteria pollutant and air toxic measurement and standards, Corporate Average Fuel Economy testing, and associated fuel economy labeling requirements. Background. On December 7, 2009, the Obama Administration signed two distinct findings regarding GHGs under section 202(a) of the Act: Endangerment Finding. Current and projected concentrations of the six key well-mixed greenhouse gases – carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and sulfur hexafluoride (SF6) – in the atmosphere threaten the public health and welfare of current and future generations. Cause or Contribute Finding. The combined emissions of the well-mixed GHGs from new motor vehicles and new motor vehicle engines contribute to the GHG pollution that threatens public health and welfare. On January 20, 2025, President Trump signed an Executive Order directing the EPA to submit recommendations regarding the legality and continuing applicability of the Finding. Following that directive, the EPA announced last summer that it was reconsidering the Finding, culminating in this week’s anticipated formal rescinding of the Finding.

The International Court of Justice (ICJ) today released its unanimous advisory opinion on obligations of States in respect of climate change (the Advisory Opinion). The Advisory Opinion, delivered by Judge Yuji Iwasawa and non-binding, determined that States may face legal consequences under international law for failing to meet their obligations to address climate change and protect the environment. This bulletin briefly summarizes background information, key findings of the Advisory Opinion, and highlights from separate opinions of ICJ judges delivered alongside the Advisory Opinion. Background. On 29 March 2023, the General Assembly of the United Nations adopted a resolution requesting the ICJ to give an advisory opinion on the following questions: (a) What are the obligations of States under international law to ensure the protection of the climate system and other parts of the environment from anthropogenic emissions of greenhouse gases (GHG) for States and for present and future generations? (b) What are the legal consequences under these obligations for States where they, by their acts and omissions, have caused significant harm to the climate system and other parts of the environment, with respect to: (i) States, including, in particular, small island developing States, which due to their geographical circumstances and level of development, are injured or specially affected by or are particularly vulnerable to the adverse effects of climate change? (ii) Peoples and individuals of the present and future generations affected by the adverse effects of climate change? Key findings. Key findings of the Advisory Opinion in response to question (a) include: International climate change treaties, including the United Nations Framework Convention of Climate Change (UNFCCC), Kyoto Protocol (KP) and the Paris Agreement (PA), set forth binding obligations for States parties to ensure the protection of the climate system and other parts of the environment from anthropogenic GHG emissions. Customary international law sets forth obligations for States to ensure the…
The Group of Seven (G7) recently published the Climate, Energy and Environment Ministers’ Meeting Communiqué following the G7 Ministers’ Meeting on Climate, Energy and Environment held last week in Turin, Italy. This marked the first meeting of G7 climate, energy and environment ministers (the Ministers) since COP28 last November and included renewed commitments on strengthening energy security, greenhouse gas (GHG) emission reduction, limiting global temperature increases to 1.5°C, and the imperative of transitioning to cleaner energy sources for economic growth and climate resilience. We view the Ministers’ renewed dedication to energy transition as the meeting’s most significant outcome, although it is important to note that countries heavily reliant on coal maintain some degree of flexibility. This bulletin briefly highlights key commitments made by the Ministers. Carbon Markets. Key carbon market commitments include: work jointly towards delivering robust outcomes from the Work Programme on Article 6 at COP29 in Baku, Azerbaijan later this year; explore innovative options for carbon markets and carbon pricing to contribute to mobilizing public and private contributions to climate finance; and enhance demand and robust certification standards for carbon dioxide removals. Energy. Key energy commitments include: phase out existing unabated coal power generation in energy systems during the first half of 2030s or in a timeline consistent with keeping a limit of 1.5°C temperature rise within reach, in line with national net-zero pathways; setting a global target of reaching 1,500 GW of energy storage in the electricity sector by 2030, six times more than in 2022; reduce demand for and use of fossil fuels, including by rapidly scaling-up clean technologies in power generation, transportation and other end users; and phase out inefficient fossil fuel subsidies, with all countries committing to a progress report in 2025, when Canada will have the Presidency of the G7 (read our earlier bulletin on Canada’s inefficient…
The District Court of Amsterdam (the Court) recently released its decision on alleged ‘greenwashing’ claims against Dutch airline KLM (the Decision). The Court found that 15 of the 19 impugned KLM advertising statements and environmental claims were unlawful and misleading to consumers. Specifically, the Court held that it was misleading and unlawful for KLM to make advertising statements suggesting that (i) flying can be or become sustainable, and (ii) the purchase of or contribution to a “compensation” product actually reduces, absorbs or compensates for part of the climate impact of flying. This bulletin briefly summarizes the background of the case and important aspects and implications of the Decision. Background. Dutch environmental groups Fossielvrij Netherlands (Fossil Free Netherlands) and Reclame Fossielvrij (Fossil Free Advertising) (together, FF), supported by ClientEarth, an international environmental advocacy organization, delivered a letter to KLM in May 2022 stating their intention to file a legal claim if their demands, including calling for a ban on all fossil fuel advertising in the EU, were not met. FF and ClientEarth indicated that they were targeting KLM’s ‘Fly Responsibly’ ad campaign and the airline’s offers for customers to purchase carbon offsets to fund reforestation projects or the purchase of biofuels to offset the emissions from a customer’s flight. FF filed a ‘greenwashing’ lawsuit against KLM in July 2022, alleging that the airline’s climate-related advertising misled the public and challenging KLM’s carbon offsetting marketing, which purported to allow customers to reduce the carbon impacts of their flights by supporting reforestation projects or the purchase of small quantities of biofuels and Sustainable Aviation Fuel (SAF). Court’s Findings and Decision. The Court considered 19 statements made by KLM in connection with its ‘Fly Responsibly’ and ‘CO2ZERO’ marketing campaigns and ‘KLM Real Deal Days’ promotion campaign under the Dutch Unfair Commercial Practices Act and…
The Intergovernmental Panel on Climate Change (IPCC) announced the finalization of its Synthesis Report of the IPCC Sixth Assessment Report (AR6) during its 58th Session held in Interlaken, Switzerland, March 13-19, 2023. The IPCC also published a Summary for Policymakers (the Summary) in advance of the release of the Synthesis Report, as well as a Longer Report and a Presentation. The Synthesis Report integrates the main findings of the AR6 and provides an overview of the state of knowledge of climate change, its widespread impacts and risks, and climate change mitigation and adaptation. The Synthesis Report has been highly anticipated and is the last of the Sixth Assessment Report products, due for release in time to inform the 2023 Global Stocktake under the United Nations Framework Convention on Climate Change. It provides an unprecedented level of scientific analysis and indicates that there are numerous, feasible, and effective options currently available to reduce greenhouse gas (GHG) emissions and adapt to human-caused climate change. Media reports from the New York Times emphasized that the Earth is likely to cross a critical global warming threshold by 2030 without rapid and drastic reductions in global GHG emissions. Reuters, quoting from the Summary, noted that “there is a rapidly closing window of opportunity to secure a livable and sustainable future for all”. This bulletin briefly highlights key findings of the Synthesis Report included in the Summary. The Summary is divided into the following three sections: Current Status and Trends, which covers the historical and present period. Future Climate Change, Risks, and Long-Term Responses, which addresses projected futures up to 2100 and beyond. Responses in the Near Term, which considers current international policy timeframes, and the time interval between now and 2030-2040. Current Status and Trends. The Summary notes that: Human activities, principally through emissions of GHGs have unequivocally caused global warming, with global surface temperature reaching 1.1°C above 1850–1900 in 2011–2020,…
