Air pollution control

Air pollution control addresses emissions from industry, heating, transport, agriculture and consumer products, as well as ambient air quality. Swiss law combines preventive emission limits, best available or appropriate technical measures, fuel and equipment standards, permits, monitoring and action plans where pollution remains excessive. It protects human health, ecosystems, buildings and climate-related interests, though climate law and air-quality law are distinct. Legal issues include retrofitting duties, operating restrictions, odour and particulate emissions, agricultural ammonia, traffic measures and the proportionality of costly improvements.
