Explained: How Methane Emissions Threaten Climate Goals
Fast-rising methane emissions could undermine efforts to limit global warming by mid-century, prompting scientists and policymakers to urge aggressive action to curb output of the potent greenhouse gas. Nearly 160 countries have pledged a 30% cut from 2020 methane emissions levels by the end of this decade. Over the last five years atmospheric methane levels have risen at their fastest rate since record-keeping began in the 1970s, driven in part by natural sources, according to the 2024 Global Methane Budget report. Here is why controlling methane emissions is so important: HEAT-TRAPPING POWER Methane molecules are more powerful than carbon dioxide (CO2) in trapping heat, meaning it takes fewer of them to cause the same amount of warming and reducing them can have a more immediate effect than reducing CO2. Tackling methane also makes financial sense. United Nations analyses have found cutting methane emissions is likely cheaper than CO2 cuts for a comparable climate benefit. W
