The oil, gas and coal industries are emitting “vastly” more of the potent greenhouse gas methane than was previously thought, and curbing these emissions could provide rapid benefits to the planet, a study has found. After carbon dioxide, methane is the second biggest contributor to global warming, and levels in the atmosphere have increased by about 150 per cent since the industrial revolution. Though there is less of it than CO2, methane’s greenhouse effect is around 80 times more potent. And unlike CO2, which can remain in the Earth’s atmosphere for around a century after it is emitted, methane lasts for less than a decade, meaning the impacts of reduction could be felt relatively quickly.
