Neogames Finland ry. and Suomen Pelinkehittäjät ry. have built a model for Finnish game companies to estimate their carbon footprint. The model unites the methodologies leading Finnish game developer studios currently use to calculate their emissions with existing third-party online resources, such as Ilmastolaskuri by WWF Finland.
The model is free to use for any company that wants to understand its carbon footprint better. It combines emissions from players playing the games, office electricity, heating and cooling, wastes and purchases, working from home and travelling. The model (updated on October 2022) can be downloaded from here.
