Methane reduction in a divided regulatory landscape: what it means for decarbonisation

The United States and European Union have adopted distinct regulatory approaches when it comes to reducing methane emissions and advancing global decarbonisation goals. Initially bolstered by the Inflation Reduction Act and reinforced by EPA methane rules, the U.S. framework now faces headwinds following the 2025 One Big Beautiful Bill Act, which scales back clean energy support and signals a broader rollback of federal climate incentives. This shift has introduced new uncertainty around the durability and direction of U.S. methane policy. Meanwhile, the EU’s Methane Regulation, implemented in 2024, enforces strict monitoring, reporting and reduction requirements that extend to fossil fuel imports, positioning the trading bloc as a leader in methane mitigation. Greater regulatory consistency would be a boon for operators, who are also dealing with non-binding and irregularly implemented agreements such as the Global Methane Pledge, data gaps, monitoring challenges, and economic and infrastructure barriers. Companies must take a pragmatic approach to compliance and investment, balancing technological solutions with policy uncertainty to keep decarbonisation goals within reach.
