The state of North Rhine-Westphalia supports cities in their efforts to reduce energy consumption. The aim of the state government is to initiate a total of 100 climate protection residential areas in North Rhine-Westphalia. The project "100 climate protection residential areas" is coordinated by the EnergyAgency.NRW on behalf of the Ministry of Economy, Innovation, Digitization and Energy. Residential areas that reduce CO2 emissions by at least 50% can be awarded with the Climate Protection Housing Award.
In October 2018, the state of North Rhine-Westphalia distinguished the Stegerwaldsiedlung in the Cologne district of Mülheim as the 87th climate protection estate. Of all selected projects, the Stegerwaldsiedlung is Germany's largest residential area with a comprehensive energy renovation to date. The prize was awarded by the Minister of Economic Affairs of the State of North Rhine-Westphalia. Andreas Pinkwart emphasized that the City of Cologne, the largest city in North Rhine-Westphalia, is setting a good example for SmartCity projects in Germany.
