The Green Industry Park in Freiburg aims to reduce CO2 emissions from the industrial park by 30% by 2030 and achieve climate neutrality by 2050. It covers 300 hectares and hosts over 300 companies. A climate protection manager was hired in 2017 to implement the top 20 policies identified in workshops with companies. These policies address mobility, energy management, energy efficiency, renewable energy, and public relations. One new project involves utilizing waste heat from a new soccer stadium and nearby groundwater to provide heating for the district.
