How can China allocate CO 2 reduction targets at the provincial level considering both equity and efficiency? Evidence from its Copenhagen Accord pledge

摘要

Highlights?China’s pledge at Copenhagen Accord are taken as example.?Three equity principles are applied to allocate carbon emission quotas.?The allocation results based on Pays ability egalitarian are selected as constraint condition in MFCAM.?The regions with higher input-output efficiency obtain more quotas.AbstractIt is crucial for China to allocate national carbon abatement targets fairly and efficiently. Essentially, the issue of national target allocation is carbon emission quotas allocation among provinces in China. In the case of China’s pledge at Copenhagen Accord, this study employs a modified Fixed Cost Allocation Model (FCAM) to determine permitted emissions of each province in China based on provincial carbon allocation results following Equity principle. Equity principles for carbon emission quotas allocation in our study contain Historical egalitarian, Population egalitarian and Pay
