building for zero – 2021

Almost 40% of global carbon emissions can be attributed to the building sector (Global Alliance for Buildings and Construction 2019). This makes the built environment both a challenge and an opportunity in terms of mitigating climate change. To further understand the implications of global carbon budgets on buildings, housing policy and development, we present an interactive model for carbon emissions from buildings between 2020 and 2050.
