ABSTRACT
This chapter quantifies China's needs for emission reduction under the dual goals in 2030 by setting three scenarios for peak emissions. Four initial allocation schemes of carbon emission allowance (CEA) are compared according to the emission abatement costs (EACs) of China and its 30 provinces. By estimating the provincial marginal abatement cost curves, China's ETS is simulated through a nonlinear programming aimed at minimizing its total EACs. We find that in achieving the dual goals it makes economic sense to operationalize the ETS that would reduce China's EACs by 61.41%–80.33% in 2016–2030, at a carbon price of 394.55–425.75 RMB per ton CO2. Peaking China's emissions in 2030 is the preferred choice that will trigger the largest GDP in 2016–2030. The historical responsibility scheme is recommended for the CEA allocation because of the lowest initial EACs without ETS. To allow more room for economic growth after China peaks emissions, there is a need for overfulfilling the goal of carbon intensity reduction by 2030, which is consistent with China's latest climate mitigation targets.
