Methane emissions from the vitality sector rose for a 3rd consecutive 12 months in 2022, coming near their earlier document degree as vitality firms are neglecting low cost, available methods to convey down their greenhouse-gas emissions, the International Energy Agency mentioned.
The enhance comes regardless of a 12 months of hovering vitality costs and as international efforts to combat greenhouse-gas emissions that drive local weather change accelerated, the Paris-based company mentioned Tuesday.
The explosions of the Nord Stream pipelines, which noticed greenhouse gasses bubble to the floor of the Baltic Sea over a number of days in late September, additionally added to the rise.
Energy sector emissions rose to 135 million metric tons in 2022, the IEA mentioned in its Global Methane Tracker report. The enhance is the third consecutive yearly rise and brings vitality sector emissions near their highest-ever degree, which was reached in 2019.
Methane, a greenhouse gasoline very similar to carbon dioxide, is believed to be accountable for round 30% of the rise in international temperatures because the Industrial Revolution, the company estimates. Methane doesn’t final as lengthy within the ambiance as carbon dioxide however contributes extra to international warming, ton for ton.
Energy firms, which launch methane as a by-product of oil and gasoline manufacturing or from coal mining, are behind 40% of human-caused methane emissions, second solely to agriculture, in keeping with the IEA. Cutting methane emissions is contemplating some of the fast and efficient methods to restrict international warming within the brief time period, the IEA mentioned.
Coal, pure gasoline and oil manufacturing every accounted for round 40 million tons of methane emissions, whereas biomass was accountable for 10 million tons. Leaks from vitality infrastructure such because the Nord Stream explosions added an extra 5 million tons of emissions.
The rise signifies that vitality firms aren’t doing sufficient to sort out the problems, regardless of cost-effective applied sciences that might considerably cut back their methane emissions and with it a key driver of local weather change, the IEA mentioned.
“Some progress is being made but… emissions are still far too high and not falling fast enough,” mentioned Fatih Birol, govt director of the IEA. “Especially as methane cuts are among the cheapest options to limit near-term global warming. There is just no excuse.”
Some 70% of methane emissions from oil, gasoline and coal firms could possibly be lowered with current applied sciences, corresponding to steps to seize and promote methane gasoline or making certain gasoline deliberately launched is burnt fairly than escaping into the ambiance, the IEA mentioned.
Similarly, oil and gasoline firms ought to make investments extra in figuring out and shortly repairing unintentional methane leaks and upgrading outdated, leaky tools. Coal miners, which launch methane when seams of coal within the floor are opened, ought to spend money on know-how that captures and makes use of the methane gasses or burns it off.
A collection of very giant leaks of methane, together with from the Nord Stream pipelines following a collection of blasts, additionally contributed to the rise. While the pipelines’ rupture contributed an enormous quantity of methane emissions in a single occasion, the quantity launched was nonetheless small in comparison with what vitality firms launch every day, the IEA mentioned.
