世界卫生组织（WHO）2026 年 11 月 4 日发布报告称：把六项已有气候与健康措施扩大到全球规模，按模型推算每年或可避免约 160 万人死亡，并带来健康、减排与经济上的“三重红利”。措施包括高温健康预警、气候韧性饮水与环卫、洗手条件、更清洁的家庭炊事取暖能源，以及更有效的化石燃料定价。阅读时可留意 prevent、estimate、benefit、policy 等词，以及 report estimates、modelled projections 如何保留推算边界。

正文

A new World Health Organization report says six familiar climate and health steps could prevent about 1.6 million deaths each year. The report was released on 4 November 2026, just before COP31 climate talks begin in Türkiye. Its main message is clear: climate change is also a health crisis, but much of the harm can be reduced with tools that already exist.

世界卫生组织（WHO）一份新报告称，六项常见的气候与健康措施每年或可避免约160万人死亡。报告于2026年11月4日发布，恰逢COP31气候谈判即将在土耳其开始。其核心信息很清楚：气候变化也是一场健康危机，但许多危害可用现有工具加以减轻。

The six actions cover early heat-health warning systems, climate-resilient drinking water, basic sanitation, hygiene and handwashing facilities, cleaner household fuels and technologies for cooking and heating, and more efficient fossil fuel pricing policies. Taken together, the report estimates they could also help avoid 16.7 billion tonnes of carbon dioxide emissions a year. That figure equals about 31 percent of global annual greenhouse gas emissions, not counting land use and forestry.

这六项行动涵盖早期高温健康预警系统、具备气候韧性的饮用水、基本环卫、卫生与洗手设施、更清洁的家庭炊事与取暖燃料及技术，以及更有效的化石燃料定价政策。报告估计，这些措施合计每年还可帮助避免约167亿吨二氧化碳排放。该数字约相当于全球温室气体年排放量的31%，不含土地利用与林业。

WHO calls the package a “triple dividend”: healthier people, lower emissions, and stronger economies. Across five of the actions, every dollar invested is estimated to return about 24 dollars in benefits. The largest fiscal gain comes from pricing fossil fuels more efficiently, including by cutting inefficient subsidies. Those policies alone are estimated to prevent about 1.2 million deaths a year and generate about 3 trillion dollars in economic welfare benefits, plus about 5.4 trillion dollars in fiscal benefits. Heat-health warnings look especially cost-effective, with an estimated return of about 835 dollars for every dollar spent, because they can build on systems already in place.

WHO称这套措施能带来“三重红利”：更健康的人群、更低的排放，以及更强的经济。在其中五项行动上，每投入1美元估计可带来约24美元收益。最大的财政收益来自更有效地为化石燃料定价，包括削减低效补贴。仅这些政策估计每年可避免约120万人死亡，并产生约3万亿美元的经济福利收益，外加约5.4万亿美元的财政收益。高温健康预警显得尤其划算：估计每花1美元可回报约835美元，因为它们可以依托已有系统。

Director-General Tedros Adhanom Ghebreyesus said many of the worst health effects can be prevented with affordable actions, and that the biggest gains would appear in countries that need them most. The economic analysis looks at lives saved, changes in greenhouse gas emissions where evidence allows, productivity and efficiency effects, and government revenue. WHO compared scaled-up coverage with a no-scale-up path from 2024 to 2075.

本段译文

总干事谭德塞（Tedros Adhanom Ghebreyesus）说，许多最严重的健康影响可用负担得起的行动加以预防，而且最大收益会出现在最需要这些措施的国家。经济分析关注挽救的生命、在证据允许处温室气体排放的变化、生产率与效率效应，以及政府收入。WHO比较了2024年至2075年扩大覆盖与不扩大覆盖两条路径。

The findings are modelled projections, not a promise that every country will reach the same result at once. WHO notes limits such as ambitious scale-up scenarios, incomplete evidence, and uncertainty in long-term forecasts. Still, the report asks governments and financing partners to treat health as a central reason for climate action at COP31, rather than an afterthought. For readers, the useful point is practical: warning people about extreme heat, protecting water and sanitation, cleaning household energy, and pricing dirty fuels more honestly may save lives while cutting emissions.

本段译文

这些发现是模型推算，并非承诺每个国家会立刻达到同样结果。WHO也指出局限，例如雄心勃勃的扩大情景、不完整的证据，以及长期预测中的不确定性。尽管如此，报告仍呼吁各国政府与融资伙伴在COP31把健康当作气候行动的核心理由，而不是事后补充。对读者而言，有用的一点很实际：就极端高温发出预警、保护供水与环卫、清洁家庭能源，并以更诚实的方式给污染燃料定价，或许能在减排的同时挽救生命。
