Currently, less than 1% of the buildings in the world are net-zero in terms of carbon. Considering that the building sector consumes a substantial amount of energy, the world needs to rapidly move towards a decarbonized building sector & tackle climate change. At the recently held UN-Climate Action Summit at New York, USA, leaders from the national and local level launched the ‘Zero Carbon Buildings for All Initiative.’ This proposal aims to unite officials from all sectors to develop & implement policies to to accelerate decarbonization of new buildings by 2030 and existing building by 2050. Previously, zero carbon buildings were considered a target only for wealthy countries. But the current initiative is looking to implement it in all the countries irrespective of their development status.
