London mayor points to ‘terrifying scenes’ this summer amid speculation Burnham may back Jackdaw and Rosebank projects

• Sadiq Khan: This burning summer is the proof: the voices of climate denial aren’t just delusional, they’re deadly

Sadiq Khan has called on the government to commit to revamped climate action and to reduce the UK’s reliance on oil and gas, as the UK endures a summer of drought, wildfires and heatwaves.

Writing in the Guardian, the mayor of London said that Andy Burnham’s administration must reaffirm its commitment to net zero and make clear it will continue to reduce the UK’s reliance on oil and gas “to get Britain back on track.”

Production at Britain’s biggest undeveloped oil and gasfield could be delayed for months after equipment from a rig was accidentally dropped in the North Sea, the Guardian can reveal.

Andy Burnham’s new government is under pressure from the fossil fuel industry to allow oil to be retrieved from the Rosebank site despite opposition from climate campaigners and some Labour MPs.

One task awaiting new energy secretary Miatta Fahnbulleh is devising a plan to avoid a crisis by the end of the decade

Welcome to the energy secretary job, Miatta Fahnbulleh. You have a politically tricky decision to make on whether to approve production at the Jackdaw gasfield and the Rosebank oilfield. But here’s another one that can’t wait much longer: what is the broader plan to ensure Britain avoids a gas supply crisis in 2030?

By way of reminder, one of the more alarming reports published by the energy department under Ed Miliband was the one that warned of “an emerging risk” to gas supplies at the turn of the decade if an important piece of kit – an import terminal, say, or the critical 725-mile Langeled pipeline from Norway – were to be out of the action during a severe cold snap.

Selection of economist formerly at helm of green thinktank marks continuation of decarbonising Miliband era

In her first 48 hours as energy secretary, Miatta Fahnbulleh was left in no doubt about the thorny policy decision at the top of her in-tray. Protesters from Fossil Free London met her outside her new offices dressed as firefighters holding placards reading: “We’re already putting out fires, don’t start new ones.”

The MP for Peckham – a radical economist who is outspoken about the climate crisis – is a surprising choice as secretary of state for energy and net zero for those who believe the speculation in Westminster that Andy Burnham wants to approve new oil and gas drilling in the North Sea.
