Global Total Methane Emissions by Country

The United States remains the largest emitter of methane with a substantial value of 63.46 Million Metric Tons of CO2 Equivalent in 2024, reflecting a steady annual increase of 2.05% in the last year. In contrast, the United Kingdom’s emissions showed slight growth with a modest 0.077% increase year-on-year. Iceland’s emissions decreased slightly by 0.0091% over the last year. Significant increases were observed in Chile (36.54%) and Portugal (27.99%), while Italy’s emissions surged by 27.34%. Smaller emissions yet significant growth was seen in Cyprus (30.32%) and Slovenia (33.69%). Conversely, Canada and Sweden experienced declines with reductions of -2.23% and -2.39% respectively.

Over the coming years, developments in methane emissions will likely be shaped by technological advancements in methane capture and reduction, shifts in energy policies towards renewable sources, and international agreements aimed at mitigating climate change. Countries heavily reliant on agriculture and fossil fuels may still see fluctuating emissions, while policy initiatives could drive significant decreases in more progressive regions. Monitoring these trends will be essential for projecting future global methane emissions and understanding the broader impact on climate change initiatives.
