Globally 38% of energy-related CO2 emissions come from the construction sector. In China, it’s estimated to make up around a fifth of the country’s annual emissions, the second largest source. The sector shows more potential for reduction than the industry and transportation sectors.

With buildings, the carbon comes from two sources. There is embodied carbon which are the emissions related to construction, maintenance, and demolition. And then there is the carbon released from the usage of the building, typically through HVAC.
