Conservative document doubled net-zero cost to £957bn in spreadsheet error

Kemi Badenoch's 100-page Conservative conference document The Right Way puts the Climate Change Committee's net-zero cost at £957bn. The Committee's Sixth Carbon Budget figures total £478bn. Carbon Brief found the tally apparently counted a totals row as extra costs, doubling the sum. Readers will want reconciled numbers before judging the party's climate costing.
