Methane emissions from energy sector rose in 2023: IEA

“Planet-heating methane released by the fossil fuel industry rose to near record highs in 2023 despite technology available to curb this pollution at virtually no cost,” the International Energy Agency said on March 13.

“Planet-heating methane released by the fossil fuel industry rose to near record highs in 2023 despite technology available to curb this pollution at virtually no cost,” the International Energy Agency said on March 13.

“Slashing emissions of methane — second only to carbon dioxide for its contribution to global warming — is essential to meeting international targets on climate change,” the IEA said.

The Paris-based agency said failing to curb methane leaks from oil and gas projects was a "massive missed opportunity" to prevent losses and reduce emissions of the potent greenhouse gas.

"Emissions of methane from fossil fuel operations remain unacceptably high... There is no reason for emissions to remain as high as they are," IEA chief energy economist Tim Gould told reporters ahead of the release of the agency's annual Global Methane Tracker report.

But he expressed hope that this year "could mark a turning point" — if countries and fossil fuel firms turn their pollution-cutting promises into concrete policies. Methane is responsible for around 30% of the global warming experienced today, according to the UN Environment Programme.

While some 40% of methane is released from natural sources, mainly wetlands, human activities are responsible for the rest. Agriculture is the main source — methane is burped out by livestock such as cows and sheep and emitted during rice cultivation.

That is followed by the energy sector where the methane leaks from energy infrastructure — such as gas pipelines — and from deliberate releases during maintenance.
