Around the world, a considerable amount of the greenhouse gas emissions that contribute to climate change are caused by the construction and operation of buildings. The condition of the buildings and how they are managed also have a significant impact on the extent of the emissions released. With the treaty signed at the United Nations Climate Change Conference in Paris in 2015, the global community committed to restrict global warming to a maximum of two degrees by taking appropriate action. As a signatory to the Paris Agreement, the Federal Republic of Germany derived a target for itself to achieve a virtually climate-neutral building stock in Germany by the middle of the century. For a residential real estate company of our size, this gives rise to a special ecological responsibility. Vonovia aims to make a contribution to achieving this ambitious target through a number of measures in the area of climate and environmental protection.
