Reader Q&A: ask our reporters anything about fossil fuel profits and the climate crisis – live

Last week reporters Jillian Ambrose and Damian Carrington published a piece which revealed that biggest oil firms made $93bn in profits in three months amid the war in Iran and the climate crisis. They’re online now to to discuss their story and any other questions you might have

StanEthel asks: Does anyone in the fossil fuel industry accept responsibility for climate change? If they don’t, how is their denial structured: it’s not happening, it’s someone else’s fault, it’s not our fault?

Damian:

The short answer is no, and a rising tide of lawsuits against fossil fuel companies for their role in the climate crisis means that is unlikely to change anytime soon. The science is ever clearer though. An analysis published last September showed for the first time that carbon emissions from the world’s biggest fossil fuel firms were directly linked to fatal spells of hot weather.

The big oil companies were among the first to realise the dangers of global warming half a century ago. But decades of denial then followed. As the reality of climate crisis has become undeniable, the arguments of the fossil fuel industry have shifted. Gas was cleaner than coal, for example, or that carbon credits from new forests could offset emissions. Today, the industry likes to tout carbon capture and storage (CCS) as a solution. But just this week, one of CCS’s loudest cheerleaders, ExxonMobil, has started a process to sue the European Union which wants to make the company actually store a small amount of CO2.

In the first weeks of the conflict, some predicted that the government’s taxes on North Sea oil and gas would yield a £20bn tax windfall for the Treasury if surging oil and gas prices remained high over the whole year. This is because the government’s windfall tax on North Sea oil and gas, known as the Energy Profits Levy, imposes an effective headline tax rate on North Sea profits of 78%, and the Treasury collects VAT from petrol and diesel sales too.

But prices have not climbed by as much as first feared. So what can we reasonably expect? Before the war, the Office for Budget Responsibility forecast that oil and gas revenues would raise £2.7bn in the 2025/26 financial year. It also suggests that for every $10 increase to the benchmark oil price, the Exchequer can expect an extra £900m in revenue. Meanwhile, every 1p increase in the price of gas hands the Treasury an extra £55m.
