China's largest internet companies continue to rely mostly on polluting energy sources to power their cloud computing and data centers, according to a new scorecard on their green credentials published by an environmental group.
Tencent Holdings ranked first among China's nine biggest cloud providers for its transparency and use of more renewable power, though its score of 61 out of 100 was little cause for celebration. The country's largest cloud provider, Alibaba Group Holding, fell out of the top spot this year, slipping to fourth.
