Brits were misled about ‘true £70bn cost’ of Theresa May’s net zero carbon target

BRITS were misled about the cost of the Government’s net zero carbon emissions target by 2050 after Whitehall officials played down the estimated £70billion annual hit.

In bombshell emails released after a two-year FOI battle, Treasury civil servants admitted to then-Chancellor Philip Hammond that the cost of going green would likely be £20billion a year more than the £50billion figure they were told to champion publicly.

Ex-PM Theresa May legally committed the UK to Net Zero by 2050 before Boris Johnson took over in 2019 - meaning any harmful gases and emissions will have be offset.

Internal government modelling from the Department for Business showed it would be 40 per cent higher - reaching £1.275trillion by 2050.

At the time, No10 played down an estimated one trillion pound total cost of switching to a totally carbon neutral economy by 2050 and dismissed the reports that it might mean public spending would have to be cut in other areas.

Andrew Montford, Deputy Director of the Global Warming Policy Foundation which pushed the FOIs, said last night: "This shows that despite being aware of a more credible higher estimate for the cost of net zero, ministers and officials chose to conceal vital information.

"We now need to see the methodology behind these estimates, so that Parliament can properly scrutinise the cost of decarbonisation policies.”

Victoria Hewson, Head of Regulatory Affairs at the Institute of Economic Affairs, added: "To scrutinise new environmental regulations properly, Parliament and the public need access to all the relevant information. 

"It is disappointing that the Government chose to withhold this crucial cost assessment for so long, and that the Treasury's view seems to have been based on such vague projections."

EYE-WATERING COSTS

Climate researchers argue that the true cost of climate change will cost even MORE in the long term if nothing is done now.

Then-PM Theresa May was keen to rush out the commitment to net zero before she left office in 2019.

But Mr Hammond was understood to be worried about the cost to the economy in the long run, and wanted to be honest with the public about the eye-watering costs.

It comes after Boris Johnson promised Sun readers earlier this week that he wouldn't whack them with extra taxes to pay for the promise to reach a clean planet.

The Treasury has yet to reveal exactly how much the policy will cost and their workings.

Last year's interim Net Zero report said: "The final size of the cost is difficult to predict."

"This is because many of the details of how the transition will evolve are unknown. They will be determined by business decisions, consumer choices, trends in innovation and government policies over a 30-year period." 

Other more recent figures from the CCC claim the cost may be as low £16billion, as the costs of new, greener tech have come down.

Ministers are poised to to publish their much-awaited Net Zero strategy this year.

A Government source said last night: “The costs of transition are highly uncertain.”
