The Global Challenges of Climate Change for Science and Society
The Atmosphere and Climate Competence Center (ACCC) organizes “ACCC Impact Week 2026” on 14–17 April at the Sofia Cultural Centre in Vuosaari, Helsinki.
address: Kallvikinniementie 35 00980 Helsinki
We invite researchers, companies, non-governmental organizations, decision-makers, education professionals, experts in research infrastructures, as well as ACCC members to join discussions on pathways to climate neutrality. This year’s theme focuses on the challenges of climate change from the perspectives of civil society, decision-makers, and the necessary funding.
The aim of the event is to further develop existing and new forms of collaboration with ACCC’s key stakeholders. We will work together to develop practical solutions and reliable roadmaps toward carbon neutrality, a safe climate, and clean air.
- We will present ACCC’s latest research results related to interactions between the biosphere and the atmosphere, with a particular focus on carbon sinks and carbon stocks in forests, peatlands, agricultural lands, and urban environments, as well as urban air quality.
- We will discuss carbon sink monitoring systems and sustainable land use and hear from leading experts in the field.
- We will discuss climate expertise, societal impact, and policy measures to combat climate change.
- This year, we are honored to welcome the Climate Theatre to perform for us on Tuesday and Wednesday! The program includes a unique and thought-provoking performance, with dinner served during the intermission. In the second half, well-known panelists such as Mari Pantsar, Saara Kankaanrinta and Risto Isomäki will also join the discussion. (Note: different panelists each night)
