应对国际CO2减排压力的途径及我国减排潜力分析

Countermeasures against International Pressure of Reducing CO_2 Emissions and Analysis on China's Potential of CO_2 Emission Reduction

在分析国际气候变化谈判形势和我国面临的CO2减排压力后,综合国家发展规划与国内外科技研发进展,提出应对持续增加的国际CO2减排压力的八条途径。其中,通过改善能源结构、提高能源效率、全民节能减排、增大陆海碳汇、重视产能转移等国内途径,在实现现有国家发展规划的前提下,可在2005-2020年累计减排507.3亿吨CO2,以实际贡献回应国际压力;同时,通过参与科学讨论、增大排放份额等国际途径,以减轻国际压力,争取更多的时间和更大的回旋空间。从根本上看,应对国际CO2减排压力还要走依靠科技创新和进步的途径。

After analyzing the situation of international negotiation on climate change and the pressure of reducing CO2 emissions China is faced with, the paper puts forward eight countermeasures to cope with the increasing pressure, integrating national development plans with advancement of science and technology at home and abroad. Of the countermeasures, five internal ones, such as optimizing energy structure, improving energy efficiency, encouraging a nation-wide energy-saving movement, augmenting terrestrial and oceanic sink for CO2, and recognizing production transfer, will reduce a total of 50.73 billion t of CO2 emissions after national development plans are realized. It will be a substantial contribution of China to the international mitigation effort and is also an effective answer to the international pressure. Two external measures, such as participating in scientific debate and bidding for a larger emitting share, will alleviate some international pressure and obtain more time and more space for China. The last one is related to science and technology innovation.
