Material and carbon footprint calculations

We offer carbon and material footprint calculations and consultancy for companies, authorities, research institutes, and other actors that help our partners enable low-carbon and resource-efficient production and consumption.

Climate Puzzle

The Climate Puzzle demonstrates how and how much our consumption habits should change to reach a climate-friendly lifestyle. It puts lifestyle carbon footprint results into perspective and offers over 100 sustainable actions for lowering the footprint. The Climate Puzzle also provokes discussion on how
and who could help make low-carbon actions faster and easier. This diverse planning and education game is suitable for youth and adults, and it can be played individually or in groups. 
The Climate Puzzle is currently available in Finnish, Swedish and English.
