The government’s net zero strategy doesn’t add up

The commitment to reach ‘net zero’ emissions by 2050 is the most expensive government proposal in modern history. Yet it was rushed through parliament with minimal debate or scrutiny, thanks to a last-minute pledge by Theresa May in 2019, weeks before she left office. She had no credible plan, just a lofty ambition without costings. It has taken the government two-and-a-half years to come up with a proposal — and it is not convincing.

The Net Zero Strategy document published this week opens with the Prime Minister’s trademark optimism. ‘We can build back greener, without so much as a hair shirt in sight,’ he writes. ‘In 2050, we will still be driving cars, flying planes and heating our homes, but our cars will be electric, gliding silently around our cities, our planes will be zero emission, allowing us to fly guilt-free, and our homes will be heated by cheap reliable power drawn from the winds of the North Sea.’
