英国机场扩建威胁到2050年气候目标,委员会提出警告。 UK airport expansions threaten 2050 climate goals, committee warns.

一个议会委员会警告说,英国机场扩建项目正在威胁该国具有法律约束力的2050年净零排放目标。 UK airport expansion projects are threatening the nation’s legally binding 2050 net zero emissions target, a parliamentary committee has warned. 环境审计委员会批评政府依赖诸如可持续航空燃料等未经证实的技术, 也批评政府未能证明经济效益超过气候和环境成本。 The Environmental Audit Committee criticized the government’s reliance on unproven technologies like sustainable aviation fuel and its failure to prove that economic benefits outweigh climate and environmental costs. 在没有飞行限制或需求管理措施的情况下,委员会敦促政府停止重大扩建,直到它能够表明它们如何与气候目标保持一致,尤其是在更新过时的2018年机场国家政策声明之前。 With no flight limits or demand management measures in place, the committee urged the government to halt major expansions until it can demonstrate how they align with climate goals, especially before updating the outdated 2018 Airports National Policy Statement. 报告重点介绍了在希思罗、加特威克、曼彻斯特、斯坦斯特德和卢顿正在进行的项目,并警告说,如果没有强有力的非碳化战略,扩大能力将有可能使进展脱轨。 The report highlights ongoing projects at Heathrow, Gatwick, Manchester, Stansted, and Luton, warning that expanding capacity without a robust decarbonization strategy risks derailing progress. 委员会主席Toby Perkins强调,迫切需要有可信的替代办法,而气候倡导者则称扩大议程鲁莽,偏向富裕的旅行者。 Committee chair Toby Perkins emphasized the urgency of credible alternatives, while climate advocates called the expansion agenda reckless and biased toward wealthy travelers.
