GHGSat 2025 Methane Emissions Report: 702 MtCO2e Detected Across 127 Countries
The GHGSat 2025 Methane Emissions Report lands at a moment when the case for measuring methane rather than estimating it has never been stronger. A peer-reviewed study cited in this year’s report found that satellite-quantified methane exceeds UNFCCC-reported emissions by 15% globally, rising to 32% for oil and gas. The full report breaks down exactly where that gap is largest, sector by sector and region by region, using a year of satellite and aircraft data across nearly 3 million facilities.
In 2025, GHGSat’s satellites and aircraft detected 28,224 methane plumes across oil and gas, waste, and mining operations in 127 countries. Download the full report to see where the emissions are coming from, how the data compares to official inventories, and what’s ahead in 2026.
