dividing the carbon benefits level of the data center into 4 levels according to the quadrant in which the data center is located;
a first grade: the carbon emission level is high, the emission reduction potential is also large, a good effect can be obtained by reducing carbon for the data center, and the whole carbon emission level of the data center is effectively reduced;
a second stage: the carbon emission level is low, but the emission reduction potential is also large, carbon reduction is performed on the data center, and although the contribution to the whole carbon emission reduction of the data center is small, a good effect can be achieved on the specific data center;
third level: the carbon emission level is low, the emission reduction potential is small, the carbon reduction is carried out on the data center, the effect on the whole and single data centers is not obvious, and the emission reduction priority should be properly reduced;
fourth level: carbon emissions levels are high, but emission reduction potential is small, and for such data centers, carbon reduction is recommended to be implemented in view of other measures.
