The Atmosphere and Climate Competence Center (ACCC) is a Finnish Flagship constituted by the University of Helsinki, Tampere University, University of Eastern Finland and the Finnish Meteorological Institute are working to address two of the most urgent global Grand Challenges: climate change and deteriorating air quality.
Our mission at ACCC is to contribute toward achieving carbon neutrality in Finland, EU and global societies, and to mitigate air pollution by providing the science behind it and sustain a healthy atmosphere. At ACCC we are finding ways to take CO2 out from the atmosphere and reliably verify it. We assess the climate neutrality of mitigation measures and air quality management actions. We contribute to the solutions that help businesses reach the Paris climate targets, to mitigate and adapt to climate change, and thus support the EU Green Deal commitments and the UN SDGs (sustainable development goals).
Our vision is safe climate and clean air.

The ACCC Flagship is funded by the Academy of Finland grant number 337549.
