Badenoch repeatedly used the phrase in <a href=\"https:\/\/www.theguardian.com\/politics\/2026\/oct\/07\/tories-prioritising-rich-voters-inheritance-tax-cut-badenoch-conference-speech\" data-link-name=\"in body link\" rel=\"nofollow noopener\" target=\"_blank\">her main speech<\/a>.<\/p>\n<p class=\"dcr-1s160rg\">Justifying the Conservatives\u2019 decision to scrap the target of the UK reaching net zero emissions by 2050, introduced under Theresa May, the document says that estimates of how much this would cost the economy \u201chave varied enormously\u201d.<\/p>\n<p class=\"dcr-1s160rg\">It goes on: \u201cIn 2020, the <a href=\"https:\/\/www.theguardian.com\/environment\/committee-on-climate-change\" data-link-name=\"in body link\" data-component=\"auto-linked-tag\" rel=\"nofollow noopener\" target=\"_blank\">Climate Change Committee<\/a> (CCC) estimated that its route to net zero would cost \u00a3957bn.\u201d It cites the Sixth Carbon Budget produced by the CCC, the government\u2019s climate change advisers, saying the report put gross economic costs at \u00a31.4tn, falling to \u00a3957bn when savings were taken into account.<\/p>\n<p class=\"dcr-1s160rg\">However, the figures in the report in fact total \u00a3478bn, half of what the Tory document said. The error appears to have arisen because a tally of all the costs in <a href=\"https:\/\/www.theccc.org.uk\/wp-content\/uploads\/2020\/12\/The-Sixth-Carbon-Budget-Charts-and-data-in-the-report.xlsb\" data-link-name=\"in body link\" rel=\"nofollow noopener\" target=\"_blank\">a CCC spreadsheet<\/a> from the document also included the row showing totals for each individual column, thus doubling it.<\/p>\n<p class=\"dcr-1s160rg\">A CCC spokesperson said: \u201cWe don\u2019t recognise this number. The committee has previously offered to meet with Ms Badenoch and talk her through our advice. That offer is, of course, still open.\u201d<\/p>\n<p class=\"dcr-1s160rg\">The committee\u2019s most recent analysis puts the expected cost of achieving net zero by 2050 at about \u00a3110bn, or about \u00a34bn a year \u2013 0.2% of GDP.<\/p>\n<p class=\"dcr-1s160rg\">The error was spotted <a href=\"https:\/\/www.carbonbrief.org\/factcheck-uk-conservatives-double-the-cost-of-net-zero-after-spreadsheet-blunder\" data-link-name=\"in body link\" rel=\"nofollow noopener\" target=\"_blank\">by the publication<\/a> Carbon Brief, which informed the Guardian.<\/p>\n<p class=\"dcr-1s160rg\">It is possible the Conservatives copied the figure without checking it. It appears to have been published <a href=\"https:\/\/iea.org.uk\/wp-content\/uploads\/2026\/01\/Turver-Cost-of-Net-Zero-Set-final-03.pdf\" data-link-name=\"in body link\" rel=\"nofollow noopener\" target=\"_blank\">in a report<\/a> by the rightwing thinktank the Institute of Economic Affairs and also included in <a href=\"https:\/\/spectator.com\/article\/how-much-will-net-zero-cost\/\" data-link-name=\"in body link\" rel=\"nofollow noopener\" target=\"_blank\">an article<\/a> in the Spectator.<\/p>\n<p class=\"dcr-1s160rg\">The Conservative document says it is intended to be a precise diagnosis of the UK\u2019s problems. It is modelled in part on The Right Approach, produced by Margaret Thatcher\u2019s Tory party in 1976, which set out some of the economic ideas later used in the 1979 election.<\/p>\n<p class=\"dcr-1s160rg\">In a foreword, Badenoch notes that \u201cas an engineer\u201d, she is used to correctly diagnosing issues so they can be addressed. A later part of the report says: \u201cTo fix a problem we must first have an accurate understanding of what is causing it.\u201d<\/p>\n<p class=\"dcr-1s160rg\">The Conservatives and Badenoch\u2019s office were contacted for comment.<\/p>\n","protected":false},"excerpt":{"rendered":"Kemi Badenoch\u2019s flagship party conference policy document overestimated the cost of net zero by nearly \u00a3500bn, seemingly after&hellip;\n","protected":false},"author":2,"featured_media":796805,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[3],"tags":[59,57,58,50,56,54,55],"class_list":["post-796804","post","type-post","status-publish","format-standard","has-post-thumbnail","category-united-kingdom","tag-gb","tag-great-britain","tag-greatbritain","tag-news","tag-uk","tag-united-kingdom","tag-unitedkingdom"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/posts\/796804","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/comments?post=796804"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/posts\/796804\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/media\/796805"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/media?parent=796804"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/categories?post=796804"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/tags?post=796804"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
