For the first time, with the help of satellites huge plumes of methane gas have been spotted. These emissions are largely unintentional but still very harmful for the climate, from coal and oil fields across the globe. Last year's IPCC study suggested that 30 to 50% of the current rise in temp is due to methane. Methane is released from coal mines and oil pipelines due to leakage or during repair. Oil companies and coal mining companies often fabricate their methane emissions, but soon enough with new and advanced sensors, it will be almost impossible to hide methane emissions. During COP26 in Glasgow, 100 countries signed the methane pledge aiming to decrease the methane emission by 30% from 2020 levels.
"We knew about individual gas blow-outs before, but this work shows the true methane footprint of oil and gas operations around the planet", explains Riley Duren, an author of the paper and CEO of Carbon Mapper which tracks methane emissions.
