Opposition in wealthier areas is likely and overcoming it is essential, says Resolution Foundation

The government will need to “take on net-zero nimbys” and ramp up public investment to decarbonise Britain’s homes, transport and electricity system, a leading thinktank has said.

With Keir Starmer promising a rapid transition to decarbonise the power system by 2030, a report by the Resolution Foundation said achieving the target would require more government spending and private investment.

Ed Miliband has won the argument that his party must go big to cut carbon emissions. But he will need to go bigger still

Sir Keir Starmer’s legislative plan to green Britain has arrived not a moment too soon. Last week, the government’s advisers warned that only a third of the carbon reductions required by law would be met under existing plans. The Climate Change Committee said that, for the first time since setting itself carbon-reduction targets, the UK is not on track to meet its goal. It is supposed to reduce emissions in 2030 by 68% compared with 1990 levels, to meet net zero by 2050.

The UK should, says the committee, now be in a phase of rapid investment and delivery. But the Tories’ turn against net zero policies has meant little progress on the rollout of low-carbon technology. That is why Labour’s king’s speech, which put the environment at the centre of policymaking, was so welcome. Ed Miliband, the energy secretary, won the argument that the urgency of the climate emergency needed a bigger, more interventionist state.

AI-based system designed to help people assess immediate risk of getting ill from water polluted with bacteria

Real-time water quality monitors are being installed at wild swimming spots and beaches across southern England to help people assess their immediate risk of getting ill from polluted water.

Wessex Water is installing sensors at three freshwater sites in Dorset, Somerset and Hampshire, plus two coastal sites in Bournemouth, after a successful pilot study at Warleigh Weir near Bath. Here, the artificial intelligence-based system correctly predicted when bacteria in the water were high 87% of the time.

Sparrows were taken into captivity after numbers dwindled – and this week experts released 1,000th bird back into wild

Scientists in Florida are hailing the landmark release this week of a tiny bird only 5in tall as an oversized success in their fight to save a critically endangered species.

Numbers of the Florida grasshopper sparrow, seen only in prairies in central regions of the state, dwindled so severely by 2015, mostly through habitat loss, that authorities took the decision to remove remaining breeding pairs into captivity. Their wager was that a controlled repopulation program would be more successful than leaving the birds to their own devices.
