Coronavirus has confined human activities, which caused significant reductions in coal, oil, and natural gas consumptions in China since January of 2020. We compile industrial, transport, and construction data to estimate the reductions in energy-related CO emissions during the first quarter of 2020 in China. Our results show that the fossil fuel related CO emissions decreased by 18.7% (182 MtCO) in the first quarter of 2020 compared with the same period last year, including reductions of 12.2% (92 MtCO) in industry sectors, 61.9% (62 MtCO) in transport, and 23.9% (28 MtCO) in construction. The figure in annual CO emission reductions is expected to limit with an estimate of 1.6%. However, to achieve the economic target for the 13th Five-Year-Plan, stimulus packages including investments in "shovel-ready" infrastructure projects issued by China's central and local governments to response the COVID-19 may increase CO emissions with a higher speed in the coming years. Thus, sustainable stimulus packages are needed for accelerating China's climate goals.
新冠病毒限制了人类活动，自2020年1月以来，中国的煤炭、石油和天然气消费量大幅下降。我们汇总了工业、交通和建筑数据，以估算2020年第一季度中国与能源相关的二氧化碳排放量的减少量。我们的结果显示，与去年同期相比，2020年第一季度与化石燃料相关的二氧化碳排放量下降了18.7%（1.82亿吨二氧化碳），其中工业部门减少了12.2%（9200万吨二氧化碳），交通部门减少了61.9%（6200万吨二氧化碳），建筑部门减少了23.9%（2800万吨二氧化碳）。预计年度二氧化碳减排量将限制在1.6%。然而，为实现“十三五”规划的经济目标，中国中央和地方政府为应对新冠疫情而出台的包括投资“具备开工条件”的基础设施项目在内的刺激计划，可能会在未来几年使二氧化碳排放量以更快的速度增长。因此，需要可持续的刺激计划来加速中国的气候目标。
