1995—2015年天津市能源消费碳足迹变化

Changes of Carbon Footprint in Tianjin Energy Consumption, 1995-2015

基于能源消费碳足迹的相关概念及计算方法,对天津市1995—2015年能源消费总碳足迹、各能源消费碳足迹、碳足迹产值、碳足迹强度和碳足迹生态压力进行分析。研究结果表明:天津市能源消费碳足迹由1995年的0.295hm2/人增加到2013年的最大值0.534hm2/人,之后呈下降趋势,2015年为0.490hm2/人;能源消费碳足迹以煤炭和石油为主,天然气所占比例最小。在未来的发展中,主要应该从减小能源消费碳足迹方面着手,采取有效的措施如提高能源利用效率和大力发展清洁能源、优先选择带有低碳产品标志的能源消费品等,来缓解天津市能源消费碳足迹对自然生态系统的压力。

Using relevant definitions and calculating methods of carbon footprint for energy consumption,the thesis analyzes the total carbon footprint of energy consumption,carbon footprints of different kinds of energy consumption,the carbon footprint output,the intensity of carbon footprint and ecological pressure of carbon footprint of Tianjin from1995to2015.It finds that Tianjin energy consumption carbon footprint increased from0.295hm2per person in1995to the maximum of0.534hm2per person in2013,then decreased to0.490hm2per person in2015.Carbon footprint in energy consumption were basically from coal and petroleum,with natural gas accounting for the lowest proportion.In the future,we should decrease carbon footprint in energy consumption,taking effective measures such as increasing energy efficiency,making major efforts to develop clean energy and prioritizing to choose energy products with low-carbon signs,in order to relieve the stress of energy consumption carbon footprint to the natural ecological system.
