Scientists say global methane emissions has come from exploiting shale gas
The boom in fracking for shale gas has ‘dramatically increased’ global methane emissions in the past decade, a study has warned.
Much of the rapid rise in levels of methane, a significant greenhouse gas has been attributed to cows, tropical wetlands and rice fields but fracking also played a role.
Researchers from Cornell University looked at the ‘chemical fingerprint’ of methane in the atmosphere and found a third of methane emissions in the past decade came from shale gas.
Around a third of the total increased emissions from all sources globally over the past decade is down to shale gas production, according to the study published in Biogeosciences, a journal of the European Geosciences Union.
