Abstract:
On the basis of sorting out the correlation between water resource behavior and the goals of carbon peak and carbon neutrality, the action mechanism and the measure problems of water resources behaviors (WRB) on the carbon peak and carbon neutrality goals were described. From the four dimensions of water resource development, allocation, utilization and protection, the CO2 emission equivalent analysis (CEEA) method of WRBs was proposed, and the CO2 emission equivalent analysis function table (FT-CEEA) was given, including the calculation formula of carbon dioxide emission equivalent (CEE) of 16 kinds of WRBs. The purpose is to provide a reference "ruler" for accounting CO2 emission in the water sector. Then, taking Henan Province as an example, the application research of CEEA method was carried out. The results showed that: (1) The total CEE of WRBs in Henan Province in 2020 was 28.886 1 million tons, and water resource utilization behavior (WRUB) was the main contributor; (2) CO2 emission effect is generated by water resource exploitation behavior (WRDB), water resource allocation behavior (WRAB) and water resource utilization behavior (WRUB), and CO2 absorption effect is generated by water resource conservation behavior (WRPB). The CEE of the four types of WRBs was 11.88 million tons, 5.65 million tons, 14.48 million tons, and ?3.12 million tons, respectively. The research results can provide reference for the follow-up research on CO2 emission equivalent accounting in the field of water resources.
