2020年中国低碳能源中期目标解读

Reading low carbon energy mid-term target of China by 2020

提出了关联能源强度ε与碳强度κ的一个新的能源经济参数—能源碳强度ω;并用以核算、澄清了中国政府宣布的2020年"节能(降低ε)"与"减排(CO2)"两个目标之间的关系.估算出了到2020年中国能源消耗为41亿吨标煤、人均2.93吨标煤、能源弹性系数0.5,二氧化碳排放量不超过76亿吨、占世界24.7%的目标数据;指出了实现这一宏伟目标的最重要途径:除快速发展非化石能源和煤的CCS利用外,就是产业转型和发展天然气冷热电联供能源系统,大幅度提高能效.

A new energy economic parameter ω that connects energy strength ε with carbon strength κ is proposed. It＇s used in accounting and clarifying the relation between energy saving （lowing carbon） and emission reduction （CO2 ） by 2020. It estimates that the energy consumption in China is 4. 1 billion tons of standard coal,2.93 ton per capita,the elasticity of energy is 0. 51, the emission of carbon dioxide is no more than 7600 tons, occupying 24. 7 percent of the world target. The paper points out that the most important way to realize the target is industrial transformation and developing heating and cooling system with natural gas to improve efficiency besides fast developing non-fossil energy and coal＇s CCS utilization.
