2000—2009年中国铅行业碳足迹分析及控制策略研究

Analysis of carbon footprint of Chinese lead industry during 2000 to 2009 and control strategy study

采用生命周期评价和碳足迹研究方法,对2000—2009年中国铅行业精铅生产过程中产生的碳足迹进行核算,并对其造成的碳汇成本和铅行业的收益进行研究。结果表明:(1)2000—2009年中国铅行业碳足迹总体呈增长趋势,主要原因是中国铅产业生产技术进步较为缓慢,生产过程中的能耗下降并不明显;(2)从2005年开始,铅行业收益高于其碳汇林成本,主要原因是中国精炼铅产量和国际铅价的高速增长。基于上述分析,从抑制碳排放和保证行业总体收益两方面提出了铅行业碳足迹控制策略,引导铅行业的低碳化发展。

With the help of life cycle assessment and footprinting methods, this paper accounted the carbon footprint caused by the production of refined lead in Chinese lead industry during 2000 to 2009, and studied the carbon sink forest costs and the revenue of Chinese lead industry. The results showed that： （1） The carbon footprint of Chi- nese lead industry has been increasing from 2000 to 2009, the main reason is the slow development of lead production technology and correspondingly the inconspicuous energy consumption drop; （2） From 2005, revenue of Chinese lead industry is higher than the carbon sink forest costs, the main reason are the growth of refined lead output and the rap- idly rising of lead price. Based on the above analysis, this paper proposed control strategy of carbon footprint of Chi- nese lead industry, to guide the low-carbon development of Chinese lead industry.
