Abstract

ABSTRACT We apply an index decomposition analysis to investigate the main drivers of CO2 emissions in the electricity generation sector in Spain over the period 1991–2017. We quantify the impact of five different effects: carbonization, transformation, fossil intensity, electricity intensity, and production effects. Four subperiods are identified. The relevance of the drivers changed over these subperiods. The fossil intensity, electricity intensity, and production effects played an important role in the increase in emissions during the first half of the period, and particularly from 1999 to 2005. In contrast, the carbonization and fossil intensity effects were the dominant drivers of emissions reductions between 2006 and 2010. The research allows an assessment of the impact of different measures on emissions by considering their influence on the different effects, and suggests which sets of measures could be more effective in reducing emissions.

西班牙发电二氧化碳排放的驱动因素:分解分析

我们应用指数分解分析来调查1991-2017年期间西班牙发电部门二氧化碳排放的主要驱动因素。我们量化了五种不同效应的影响:碳化、转化、化石强度、电力强度和生产效应。确定了四个子阶段。这些驱动因素的相关性在这些时间段内发生了变化。前半期，特别是1999 - 2005年，化石燃料强度、电力强度和生产效应对排放量的增加起了重要作用。相比之下，碳化和化石强度效应是2006 - 2010年减排的主要驱动因素。这项研究允许通过考虑不同措施对不同效果的影响来评估不同措施对排放的影响，并建议哪一套措施在减少排放方面可能更有效。
