The city of Riihimäki has been actively working to reduce its carbon emissions since 1998. It established an environmental policy and annual programs, calculated its CO2 emissions from 1990 to 2009, and saw a 13% reduction in consumer emissions from 1990 levels by 2009. In 2011, Riihimäki approved a Climate Strategy 2020 with goals of reducing consumer greenhouse gas emissions 25% and per capita emissions 40% by 2020 through actions related to land use, energy, buildings, transportation, procurement, education and climate adaptation. The strategy was developed over a year in collaboration with stakeholders from across the city.
