For example, a great deal of power in Taiwan is generated by coal-fired plants, so Taiwan's electricity emission factor is relatively high at 0.636. Korea uses mostly nuclear power, and has an emission factor of 0.454. In some countries where the proportion of green energy is high (e.g. Sweden and Norway), the figure is less than 0.1.
例如台灣以火力發電為大宗，碳排系數為 0.636；韓國的核電多，碳排系數為 0.454；北歐瑞典、挪威等國因「綠能」比例高，碳排系數甚至不到 0.1。
