They say reducing methane leaks from gas pipes, eliminating organic waste from landfill, and cutting meat consumption would help.
Cutting human sources of methane would be a quick win for the climate, according to a new United Nations report.
Roughly halving emissions of the greenhouse gas from human activity, often with existing, cost-effective solutions, would reduce the future rise in global temperatures by around 0.3C by the 2040s, it is claimed.
The analysis was carried out by the UN Environment Programme and the Climate and Clean Air Coalition (CCAC).
Scientists have hailed the strategy as a “win-win” because it would reduce global warming and simultaneously improve human health and the economy.
Levels of methane in the atmosphere have doubled since pre-industrial times.
It is a potent greenhouse gas that is 10 times more powerful than carbon dioxide at trapping heat in the atmosphere.
According to the UN’s Global Methane Assessment, human activity results in around 380 million tonnes of methane being released into the atmosphere every year.
