『Abstract
Power sector is the largest CO2 emitter
in China. To mitigate CO2 emissions for the
power sector is a tough task, which requires implementation of
targeted carbon mitigation policies. There might be multiple forms
for carbon mitigation policies and it is still unclear which one
is the best for China. Applying a superstructure optimisation
model for optimal planning of China's power sector built by the
authors previously, which was based on real-life plants composition
data of China's power sector in 2009, and could incorporate all
possible actions of the power sector, including plants construction,
decommission, and application of carbon capture and sequestration
(CCS) on coal-fuelled plants, the implementation effects of three
carbon mitigation policies were studied quantitatively, achieving
a conclusion that the so-called “Surplus-Punishment & Deficit-Award”
carbon tax policy is the best from the viewpoint of increasing
CO2 reduction effect and also reducing the
accumulated total coat. Based on this conclusion, the corresponding
relationships between CO2 reduction objectives
(including the accumulated total emissions reduction by the objective
year and the annual emissions reduction in the objective year)
were presented in detail. This work provides both directional
and quantitative suggestions for China to make carbon mitigation
policies in the future.
