Methane is increasing rapidly, harming the climate, and is 80 times more harmful than carbon dioxide

Recent studies have highlighted the disturbing rise in atmospheric methane, a greenhouse gas that is 80 times more effective than carbon dioxide (CO2) at trapping heat in the short term. Despite the 2021 Global Methane Pledge, which aims to reduce methane emissions by 30% by 2030, current methane levels are increasing faster than at any time in the past 40 years. This trend poses a serious threat to climate goals, as methane’s short-lived but strong warming effect accelerates global temperature increases.

Human activities drive methane growth

Human activities, including animal husbandry, fossil fuel extraction and waste management, currently account for around two-thirds of global methane emissions. Agriculture, particularly livestock and rice paddies, contributes 40%, while fossil fuels and landfills account for 36% and 17%, respectively. Recent data show a substantial increase in methane emissions from these sources, with atmospheric concentrations rising significantly since 2020.

Immediate action needed

Persistently high methane concentrations are concerning because they are consistent with scenarios that predict global warming of up to 3°C by 2100. To meet the 2015 Paris Agreement goal of limiting global warming to below 2°C, methane emissions must be cut nearly in half by 2050. Solutions include improved agricultural practices, better landfill management and enhanced methane capture technology. Immediate and substantial action is essential to curb this powerful greenhouse gas and mitigate its contribution to global warming.
