In line with the Paris Agreement, European agreements and the Climate Act, the Netherlands wants to significantly reduce CO2 emissions in the coming decades. Therefore, Rotterdam wants to be gas free and climate neutral by 2050. Currently, Rotterdam has 263,000 natural gas connections, which are mainly used for cooking, heating and hot running water. We must therefore start on time to ensure that all buildings in the city are natural gas-free before 2050. We will do this in phases, so that the city remains accessible during the heat transition and we can make optimal use of resources and people. To be able to make sufficient headway towards 2050, a number of components are required.
