The Air Pollution & Climate Secretariat is a collaborative initiative formed by four leading Swedish environmental organizations dedicated to raising awareness about air pollution and climate change. Through advocacy and public engagement, the Secretariat aims to reduce emissions of harmful air pollutants, including greenhouse gases, to levels that can be sustained without environmental harm. The organization serves as a vital information hub for European environmental groups, policymakers, and media, offering resources such as the quarterly publication Acid News, which reaches around 4,000 recipients.

Moreover, the Secretariat actively participates in lobbying efforts for better air quality regulations and climate policies, aligning with both the European Union and international conventions. By supporting local environmental movements, particularly in Eastern Europe, the Secretariat promotes initiatives surrounding energy, transport, and air pollution awareness. With a commitment to transparency and collaboration, the Air Pollution & Climate Secretariat is influential in shaping environmental strategies for a healthier future.
