今年春天影响欧洲的严重空气污染事件（见，例如，去。自然com/si 6 mhu和去。自然com/1b 7 ygf）强调，鉴于此类急性事件的持续性和潜在的全球影响力，需要采取有效的政策措施和管理战略。减少颗粒物、臭氧和温室气体对减轻空气污染和气候变化至关重要，因此需要协调政策。例如，气候政策鼓励使用柴油等燃料（因为其燃烧每公里释放的二氧化碳比汽油少）和生物质，这抵消了其自身增长过程中的大部分碳排放。然而，这两种燃料都会产生有害颗粒。就目前而言，必须调查引发欧洲最近空气污染事件并影响其持续时间和传播的因素。这一见解将有助于制定基于合理科学建议的急需的跨境政策。
The severe air-pollution episodes that affected Europe this spring (see, for example, go. nature. com/si6mhu and go. nature. com/1b7ygf) highlight the need for effective policy measures and management strategies, given the persistence and potential global reach of such acute events. Reducing particulate matter, ozone and greenhouse gases is essential to mitigate air pollution as well as climate change, so policies need to be coordinated. For example, climate policy encourages use of fuels such as diesel (because its combustion releases less carbon dioxide per kilometre than petrol) and biomass, which offsets most of its own carbon release as it grows. However, both fuels generate harmful particulates. For now, the factors that triggered Europe’s latest air-pollution episodes and influenced their duration and spread must be investigated. This insight will aid the development of much-needed cross-border policies that are based on sound scientific advice.
