Report: $75 bn needed for methane emission abatement in oil, gas sector
Around $ 75 billion in spending is required to 2030 to deploy all methane abatement measures in the oil and gas sector in the International Energy Agency (IEA)’s net zero scenario as tackling methane emissions is one of the most cost-effective ways to reduce greenhouse gas emissions, according to a recent report.
Under current trajectories, total methane emissions from human activities could rise by up to 13% between 2020 and 2030. In a scenario that limits warming to 1.5 °C, they need to fall by 30% to 60% over this timeframe. Cuts in methane emissions from fossil fuel operations will likely need to provide around half of this reduction.
The Imperative of Cutting Methane from Fossil Fuels, released t, released by the IEA in partnership with the United Nations Environment Program (UNEP), builds on findings from the IEA’s recently updated net zero pathway to limit global warming to 1.5 °C. It shows that while a drop in fossil fuel demand would cut methane emissions, these reductions by themselves would not occur fast enough to meet the world’s climate goals.
Additional targeted actions to tackle methane emissions from fossil fuel production and use – such as by eliminating routine venting and flaring and repairing leaks – are essential to limit warming to 1.5 °C and reduce the risk of crossing irreversible climate tipping points.
The new report finds that rapid cuts in methane emissions from fossil fuels could avoid up to 0.1 °C in global temperature rise by mid-century – greater than the emissions impact of immediately taking all cars and trucks in the world off the road.
As methane emissions lead to ground-level ozone pollution, immediate action would also deliver public health, food security and economic benefits. Based on modeling of the UNEP/CCAC Global Methane Assessment published in 2021 – which, for the first time, assessed and integrated the climate and air pollution costs and benefits from methane mitigation – methane action would prevent nearly 1 million premature deaths due to ozone exposure, 90 million tons of crop losses due to ozone and climate changes, and about 85 billion hours of lost labor due to extreme heat by 2050. This would generate roughly $ 260 billion in direct economic benefits through 2050.
The Global Methane Assessment formed the scientific underpinning of the Global Methane Pledge (GMP) by illustrating that there are readily available measures to achieve its goals.
“Reducing methane emissions from the energy sector is one of the best – and most affordable – opportunities to limit global warming in the near term,” IEA Executive Director Fatih Birol said. “Early actions by governments and industry to drive down methane emissions need to go hand-in-hand with reductions in fossil fuel demand and CO2 emissions. This report sets out the clear case for strong, swift action.”
“Cutting methane doesn’t let us off the hook to make good on the just energy transition. But cutting methane is a low hanging fruit while we work on the overall decarbonization of our economies in tandem with supporting our societies to build greater resilience. Investments in maintenance and operational changes that prevent methane from leaking into the atmosphere are a fraction of profits made from fossil fuels. This is in stark contrast to the cost of inaction, from crop productivity losses, to impacts on human health and the economy” said Inger Andersen, Executive Director of UNEP.
“We know what to do, we have the means to do it,” she added. “There is a support-system in place to help countries develop roadmaps, policies, and regulations, and to provide countries and companies with credible data to drive emissions reductions. We must do it now.”
