'No excuse': IEA tells energy firms as methane emissions rise

In 2022, the global energy industry released into the atmosphere some 135 million tons of methane - a potent greenhouse gas responsible for roughly a third of the rise in global temperatures since the industrial revolution.

Last year's emissions rose above 2020 and 2021 levels, and were only slightly below the record amount released in 2019, despite high energy prices and surging demand for natural gas that provided extra incentives to capture methane, the report said.

Methane is the main component of natural gas, so captured emissions can be sold as fuel.

Although some progress has been made, "emissions are still far too high and not falling fast enough - especially as methane cuts are among the cheapest options to limit near-term global warming," IEA Executive Director Fatih Birol said in a statement. "There is just no excuse."

The energy sector accounts for about 40% of all methane emissions from human activity, second to agriculture.

The IEA said methane emissions from oil and gas alone could be reduced by three-quarters with existing technologies and modest investment of less than 3% of the $4 trillion windfall income gained by oil and gas companies worldwide last year.

"The economic incentives to make those reductions were huge last year," IEA's Chief Energy Economist Tim Gould said. "We had record natural gas prices in many markets around the world. There was an extremely strong economic incentive to bring methane to market."

But despite this, "2022 was a disappointing year," he said.
