This tool enables you to interactively engage with modelled data for three possible energy mitigation scenarios for the building sector, globally and per region, by 2050. To facilitate a rapid transition to sustainable energy in the building sector, GBPN supports a deep path of ambitious policy actions based on the deep energy scenario in which state of the art in both new and existing buildings become the norm in only ten years from now. With this tool you can find out where the world could be in terms of building energy use by 2050 under several scenarios, depending on the ambitiousness of policy decisions and technology choices.
