Abstract

The Lima call for climate action adopted at the Lima Climate Conference on Climate Change specifies that the principles of the United Nations Framework Convention on Climate Change, including the principle of common but differentiated responsibilities, shall apply to the new climate agreement to be adopted at the Paris Conference on Climate Change in 2015. Decisions on other heavily debated items, including the intended nationally determined contributions, were also made at the Lima Conference. The significant achievements in Lima and the positive momentum have laid a solid foundation for the adoption of a new climate agreement in the Paris Climate Conference. Four measures are proposed for China to meet great challenges in addressing climate change beyond 2020, including early formulation and issuance of a climate change law, establishment of a greenhouse gas emission trading scheme, promotion of advanced climate technology investments, and further international engagement for climate change.

Abstract

From the perspective of life cycle assessment (LCA), the development, construction, and operation of all kinds of new energy power generation technologies release greenhouse gas (GHG) emissions. This sparks concerns about the low-carbon nature of the new energy power generation technologies. Based on national and international literature review, this paper estimates and compares the GHG emission factors of traditional thermal power generation and new energy power generation technologies in China with the LCA approach. The GHG mitigation potential of new energy power generation technologies as substitution for traditional thermal power generation in China was evaluated, according to the objectives of new energy power generation of the national development planning. The results show that the GHG emission factors of new energy power generation are much lower than that of traditional thermal power generation even with LCA accounting, and the GHG mitigation potential of new energy substitution is huge.
