摘要/Abstract

摘要：

自2011年来,中国碳排放权交易机制不断健全完善,其中基准线法被确定为全国碳交易初始配额分配的主要方法。钢铁行业作为仅次于电力行业的第二大碳排放部门,加快对其开展基准线法碳交易的测算、设计和评价,对纵深推进全国碳交易市场建设具有重要意义。文中基于2018年钢铁企业直报的温室气体排放数据和单位产品碳强度这一关键指标,确定了中国钢铁行业开展全国碳交易的基准线方案。结果显示,钢铁行业碳交易基准线应包括炼钢及之前的6个工序,基准值宜采用效率较高的前70%至80%范围内的企业碳强度均值,在配额确定时无需考虑行业区域差异,但针对企业间碳强度差异较大的工序应设立从历史法到基准线法的过渡期。

Abstract:

The national carbon emission trading scheme has been constantly improving since 2011, and the benchmark method has been determined as the major one of carbon allowance allocation. The iron and steel industry, which is the second largest contributor of energy consumption and carbon emission after the electric-power industry in China, is playing a significant role in improving the national carbon emission trading market. As a result, it is of great necessity to speed up calculation, design and evaluation of the carbon trading by benchmark methodology. Based on the data submitted directly from iron and steel enterprises to the government in 2018 and the carbon intensity per unit of product, which is the key indicator of iron and steel benchmark, this paper has determined the benchmark methodology for the national iron and steel industry carbon trading. The analysis results show that the benchmark of the iron and steel industry should include steel making and the previous six processes. The average carbon intensity of top 70% or 80% efficient enterprises is recommended as the benchmark. Furthermore, there is no need to consider the regional differences of enterprises in actual practice. However, a transition period should be set from historical method to benchmark method for some progresses where big differences exist among enterprises.
