区域碳双控下跨区电力间接碳排放核算方法
Accounting Methods for Indirect Carbon Emissions from Cross-regional Electricity under Dual Carbon Control Policies
摘要
Abstract
The accounting of cross-regional electricity indirect carbon emissions is crucial to the carbon budget management of major power-sending and power-receiving regions during China's"15th Five-Year Plan"period.To address such issues as significant inaccuracies in traditional territorial-based accounting methods and insufficient integration of green electricity certificates,four alternative accounting methods,including the power source-based emission factor method,the power import-based emission factor method,the net coal-power transfer adjustment method,and the green certificate consumption adjustment method,are proposed to quantitatively assess the scale of carbon emission transfers via cross-regional and inter-provincial electricity transmission in 2023,and the impacts of different accounting methods on regional carbon budgets are compared.The study reveals that the accounting results of indirect carbon emissions from cross-regional electricity are varied significantly with different methods,with fluctuations exceeding 10%in key power-importing regions such as East China and North China;the accounting mechanism based on the"national average emission factor adjusted with green certificates"can dynamically refine the carbon emission responsibilities of power-importing regions.It is recommended that the accounting of indirect carbon emissions from cross-regional electricity transmission should be grounded in regional coordinated development and the efficiency of power resource allocation,with comprehensive consideration of the responsibility-sharing mechanisms between sending and receiving regions as well as the green certificate system.关键词
