Shell aims to maintain methane emissions intensity below 0.2% by 2025, it said in a statement, joining British rival BP, which last year set a similar goal, Reuters reported. Methane is released into the atmosphere mostly through leaks in gas infrastructure such as pumps and pipelines. The gas has a bigger impact than carbon dioxide, even though the oil and gas industry produces less methane and the gas also has a shorter lifetime. The methane target will be measured against a baseline leak rate, which is currently estimated to range from 0.01% to 0.8% across the company’s oil and gas assets, it said. The Anglo-Dutch company set out last year an ambitious plan to halve its carbon emissions by 2050, far exceeding rivals. Investors have called on the company to set binding targets to reach those goals.
