ExxonMobil has met with senior European Commission officials at least five times since the beginning of 2025 to discuss the law or related topics.EU member states have proposed diluting the requirement for companies to “put into effect” climate mitigation plans, instead proposing only that companies adopt a plan setting out “reasonable efforts” to tackle global warming.Burning fossil fuels is the primary driver of the climate crisis, accounting for about two-thirds of annual global greenhouse gas emissions. The production of fossil fuels is linked to severe human rights and environmental harms, including toxic air, unsafe water, and polluted ecosystems.The fate of the EU’s corporate accountability law now rests with the European Parliament. Instead of succumbing to lobbying by powerful industries, parliamentarians should fight for a law that requires companies to take robust action against climate change and that holds corporations to account for human rights and environmental abuses worldwide.
