Assessing the factors behing CO2 emissions changes

CDC CLIMAT RESEARCH WORKING PAPER No, 2013-15 PAPER N° 2012-14 Assessing the factors behind CO emissions changes over the 2 phases 1 and 2 of the EU ETS: an econometric analysis 1 2Olivier Gloaguen and Emilie Alberola October 2013 Summary It has been repeatedly said that the economic slowdown that began in 2008 largely explains the fall in carbon emissions recorded in Europe since the introduction of the European Union Emissions Trading Scheme (EU ETS). In fact, the European Union stated this very clearly in its initial report on the operation of the EU ETS in November 2012. Using an econometric analysis based on a business-as- usal scenario, it is shown that reductions of around 1.1 GtCO are likely to have been achieved within 2 the scope of the 11.000 installations covered by the EU ETS. Of those reductions, between 600 and 700 million tonnes are said to have resulted from the two policies in the 2020 Climate & Energy Package, which aims to achieve a 20% renewable energy target (a decrease of around 500 million tonnes) and a 20% improvement in energy intensity (a decrease of between 100 and 200 million tonnes). The economic downturn also played a significant, although not dominant role in the decrease in CO emissions, the impact of which was estimated at 300 million tonnes. Price substitution effects 2 induced by coal and gas prices also seem to have affected emissions, within an order of magnitude of around 200 million tonnes.
