Methane Tracker 2021 – Analysis IEA

+

Converted into equivalent amounts of CO 2, assuming that one tonne of methane is equivalent to 30 tonnes of CO 2, these methane emissions are comparable to the total energyrelated CO 2 emissions of the European Union. This methane emissions figure for 2020 is around 10% lower than our estimate for 2019. A large portion of this drop occurred because of the fall in oil and gas production over ...
