The UK opposition Conservative party has published a policy booklet containing what appears to be a significant mathematical error regarding the estimated cost of achieving net-zero emissions. The document asserts that the Climate Change Committee estimated the expense at approximately £957bn, but factual analysis reveals this figure represents a doubling of the actual 2020 estimate.
The Climate Change Committee’s 2020 analysis calculated the net cost of net-zero at £478bn over a 30-year period from 2020 to 2050, accounting for both required capital expenditures and operational savings. The committee subsequently revised these figures in 2025, lowering the estimated net cost to £108bn over the 2025-2050 timeframe, primarily due to declining electric vehicle costs. The erroneous £957bn figure appears to have originated from a spreadsheet error in which figures were added together twice, conflating annual sectoral costs with combined yearly totals.
The error’s path through policy circles began with a January article by David Turver, an engineer and self-described energy analyst, who cited the miscalculated figure. Turver repeated the error in a subsequent report for the Institute of Economic Affairs, and the figure was later cited by the Great British Think Tank in March. The Conservative party’s “Right Way” policy document, published in October, then incorporated this figure without verification against the original Climate Change Committee sources.
The Climate Change Committee has consistently emphasized that net-zero investment represents a manageable economic commitment, representing less than one percent of GDP and delivering broader economic benefits. The committee’s analysis indicates that achieving net-zero would cost considerably less than a major fossil-fuel price shock and would generate annual benefits worth approximately £110bn.
