What the Evidence Shows
The claim can be broken down into two main components: 1) a Tory MP suggested addressing the climate crisis with more air conditioning, and 2) this suggestion was positioned as an alternative to achieving net zero emissions by 2050. The search results and structured sources reveal significant debate within the Conservative Party about the net zero target, with some MPs and party figures describing the 2050 net zero goal as arbitrary or not based on science.theguardian.comtheguardian.comA useful enemy?

news.sky.comnews.sky.comNet zero targets could cause more unrest and division than Brexit, Tory MP warns However, none of these sources mention any Tory MP advocating for increased air conditioning as a solution to the climate crisis. The discussions focus primarily on skepticism about the feasibility or scientific basis of net zero targets, concerns about economic costs, and political positioning rather than proposing specific countermeasures like expanding air conditioning use. Given that air conditioning typically increases energy consumption and greenhouse gas emissions unless powered by renewable energy, it would be counterintuitive for a climate policy proposal to promote more air conditioning as a mitigation strategy. The absence of any direct quotes or reports supporting this specific claim in reputable news outlets or official statements suggests it may be a misinterpretation, exaggeration, or misinformation. Without direct evidence or credible reporting confirming such a statement by a Tory MP, the claim remains unverifiable.
While some Tory MPs have expressed doubts about net zero policies and their economic impact, none have publicly proposed substituting net zero efforts with increased air conditioning. Therefore, the claim lacks substantiation in authoritative sources and should be treated cautiously.
