摘要/Abstract

摘要：

基于气候变化综合模型——全球变化评价模型（GCAM-TU),分析了2030年各国家/地区减排承诺下能源相关CO₂的全球排放路径与不同可能性下2℃温升目标对应的最优排放路径的差距。研究发现,当前减排承诺下的全球排放路径与最优路径仍存在一定差距,各国家/地区需加大2030年后的减排承诺力度。进一步分析了主要国家/地区在各自减排承诺下的碳强度下降率、减排成本和人均碳排放,得出中国在全球减排进程中的努力和贡献是巨大的,而南非、日本等国承诺力度不足。为实现自主决定贡献,中国终端能源消耗将较参考情景有所下降,能源结构将进一步优化。

Abstract:

The gap of energy-related-CO₂ emission pathways between the Nationally Determined Contributions (NDCs) submitted to United Nations Framework Convention on Climate Change (UNFCCC) and realizing the target of limiting temperature rise below 2℃ was researched based on an integrated assessment modal of climate change—Global Change Assessment Model (GCAM-TU). Results show that the NDCs are not enough to realize the target. Each country or party should enhance its NDC after 2030. The analyses of carbon intensity reduction, abatement costs, and carbon emission per capita of the main countries and parties demonstrate the great efforts and contributions of China in the process of global emission reduction. On the contrary, the commitments of regions like South Africa and Japan seem insufficient. To meet the commitment, the final energy consumption of China would reduce compared with the reference scenario, and the energy structure would have a further optimization.

Key words: Climate change, Nationally Determined Contributions (NDCs), Integrated assessment model, 2℃target
