    The western region is a destination for the transfer of data center computing capacity.It is rich in natural resources and must take full advantage of its energy and climate advantages.In the context of ＆quot;Channel Computing Resources from the East to the West＆quot;, data centers urgently need to quantify the carbon reduction benefits during the process of transferring computing capacity.Therefore, this paper constructed a carbon emission accounting model for computing capacity transfer by considering three influencing factors: renewable energy, climate factor, and transfer process.To illustrate the effectiveness, a case of eight nodes of ＆quot;Channel Computing Resources from the East to the West＆quot; was presented.The results show that compared with the carbon emission reduction from renewable energy and climate factors, the additional carbon emission caused by the transmission process is minimal, and for each 1 kW·h of computing capacity, 0.053~0.344kg of carbon emission can be reduced if only the first two factors are considered.To improve the carbon emission benefits from load shifting, the western region should guide data centers to gather in resource-intensive places, vigorously develop clean energy industries, increase the development of clean energy, and promote the degree of clean energy consumption, while grasping this opportunity to attract digital industries to land and promote the digital transformation of traditional industries.
