Andrea Egan calls for same political focus on teachers, care sector and NHS and says Jackdaw decision ‘a serious misstep’

The leader of the UK’s biggest trade union has called for the same political focus to be given to NHS, education and care sector workers as there has been on those employed in North Sea oil and gas.

Andrea Egan, the general secretary of Unison, said too often public sector workers were treated as an “afterthought” by the government compared with the “massive political focus” on protecting jobs in the North Sea.

Ex-energy secretary Ed Miliband’s agenda appears undermined as money is diverted from renewables to defence

Britain is unlikely to hit its targets on green heating after the cuts announced by John Healey this week, experts have warned, as critics of Ed Miliband claim the former energy secretary’s green agenda is being dismantled.

The chancellor unveiled more than £3bn worth of cuts to the energy department’s budget this week, much of which will pay for higher defence spending.

The radical Stern report showed that a low-carbon future is also good economics. But it seems that capitalism needs a reminder

Saving the only planet we have makes good economic sense. There is, after all, no money to be made on a dead Earth. There may be costs involved now, but they are worth paying to protect our children from certain destruction.

These propositions seem self-evident now. But two decades ago, mainstream economists had very different ideas. They had proved that the climate crisis would be a mere economic blip, easily absorbed by growing economies and therefore not worth spending money on. In their accounting, they considered ice caps and glaciers functionally worthless, that trees only add to GDP when they are cut down, and that a livable climate shouldn’t even merit a line on a spreadsheet.
