The predicted £264bn cost by 2050 could be even higher, plus renewables avoid a far higher total of emissions than can be captured, writes Andrew Boswell, while Simon Oldridge calls out vested interests

Prof Myles Allen and colleagues, in their letter (12 July) on carbon capture and storage (CCS), propose licensing gasfields on condition that producers store an increasing proportion of “the carbon dioxide their products generate”. Their proposal only considers CO₂. Methane is excluded by choice although it leaks throughout global fossil-fuel supply chains, including during extraction, processing, liquefaction and shipping.

A growing academic literature, supported by satellite observations of major methane plumes, shows that these emissions can be very substantial, and are the dominant near-term climate impact for gas supplied as liquefied natural gas.

Heatwaves, high energy prices, calls for reindustrialisation and North Sea drilling are all high on the to-do list

Wildfires cast a pall of smoke this week over Greater Manchester, whose former mayor Andy Burnham stands on the threshold of No 10. Amid three UK heatwaves so far this year, which have killed thousands of people in England and Wales, damaged harvests and left children crying in classrooms, the new prime minister’s plans for the climate crisis remain as shrouded as his city.

“Burnham has been very quiet about the climate [crisis] so far,” says Chris Venables, an environmental campaigner and fellow at the Green Alliance thinktank. “I don’t think [it] is at the forefront of his mind, but that does not mean he will water down this agenda.”
