尽管中国电力需求快速增长，但清洁能源发电的增长首次使该国的二氧化碳（CO2）排放量出现下降。 Carbon Brief的最新分析显示，2025年第一季度，中国的碳排放量同比下降了1.6%，过去12个月则下降了1%。 新增风电、太阳能和核电的装机容量所带来的出力，足以应对电力需求激增，从而削减燃煤发电量；而此前的排放下降则主要被归因于经济增长放缓。 这项基于官方数据和商业数据的分析显示，中国的碳排放量一年多来一直保持稳定或下降。 不过，该排放量仅比最近的峰值低1%，这意味着只要出现短期反弹，中国的碳排放就可能创下新高。 其他主要发现包括： 清洁能源发电增长速度已经超过当前及长期电力需求增长平均值，从而压低了化石燃料的使用量。 截至2025年3月的12个月内，电力行业的碳排放同比下降了2%。 若这一趋势得以保持，意味着中国电力行业排放可能已达峰并开始持续下降。 美国总统特朗普发动的“贸易战”促使中国更加努力将经济重心从出口转向内需。 新出台的可再生能源电价政策催生了“抢装潮”，企业争相在政策实施前完成项目建设。 如果中国要实现在《巴黎协定》下承诺的2030年排放目标，仍面临日益扩大的差距需要弥补。 上微信关注《碳简报》 如果这种因清洁能源增长而带来的电力行业碳排放下降趋势得以延续，可能预示着Carbon Brief此前在分析中预测的结构性排放下降的开始。 电力行业碳排放下降的趋势很可能在2025年继续。 然而，未来的走势在很大程度上将取决于中国即将于明年公布的下一份五年规划中所设定的清洁能源与减排目标，以及中国对特朗普政府敌对贸易政策的应对策略。 中国碳排放因清洁能源而下降 过去十年来，尽管中国化石燃料和水泥行业的碳排放量有高低起伏，但总体上升了20%。 最新数据显示，该排放量可能已经接近达峰以及趋稳，甚至正步入结构性下降的阶段。 截至2025年第一季度的最新数据显示，中国的碳排放量已经连续一年多呈现稳定或下降趋势，如下图所示。 不过，由于该排放量仅比最近的峰值低1%，这意味着其仍有可能在短期内反弹并创下新高。 因此，中国未来的碳排放走向尚未确定，这取决于各经济部门的趋势，以及中国对特朗普关税政策的应对方式。 电力行业排放下降，其它行业却现反弹 2025年第一季度中国碳排放的下降主要源于电力行业排放下降了5.8%。尽管整体电力需求增长了2.5%，但火电（主要是燃煤和燃气发电）却减少了4.7%。 由于大量新建风电、太阳能和核电装机投入运行，发电量的增长足以弥补需求的增长。水电发电量也有所上升，虽然其受季节因素影响，但同样对化石能源的替代发挥了作用。 电力行业碳排放降幅超过化石能源发电量降幅，因为生物质和天然气的占比上升，同时燃煤电厂的平均能效也有所提升。 具体而言，燃煤电厂度电煤耗平均下降了0.9%。 下图底部显示了第一季度电力行业煤炭使用造成的碳排放量减少情况，该数据低于其他行业的碳排放量变化。...
