UK substantially underestimates its methane emissions from oil and gas production – and many other countries probably do too

Envirotec Magazine

A newer, more accurate method for calculating methane emissions from offshore oil and gas production suggests that the United Kingdom severely underestimates its greenhouse gas emissions. Researchers conclude that as much as five times more methane is being leaked from oil and gas production than reported.
