Hypothetically, switching off the lights for an hour would cut CO2 emissions from power plants around the world. But, even if everyone in the entire world cut all residential lighting, and this translated entirely into CO2 reduction, it would be the equivalent of China pausing its CO2 emissions for less than four minutes.
人们想当然地认为熄灯一小时会降低全球电厂的二氧化碳排放。但即使全球所有人关闭一切住宅照明，且节省的电能完全转化为二氧化碳减排，也不过相当于中国暂停二氧化碳排放不到四分钟。事实上，“地球一小时”将会增加二氧化碳排放。
