Costs of meeting international climate targets without nuclear power / Vicki Duscha, Katja Schumacher, Joachim Schleich &#38; Pierre Buisson. Fraunhofer ISI, 2013, 45 p. (Working Paper Sustainability and Innovation N° S 7/2013)http://www.isi.fraunhofer.de/isi-media/docs/e-x/working-papers-sustainability-and-innovation/WP07-2013_Costs_of_meeting_international_climate_targets_VD.pdfAuthors's abstract :This paper assesses the impact of a global phase-out of nuclear energy on the costs of meeting international climate policy targets for 2020. The analyses are based on simulations with a global energy systems model. The phase-out of nuclear power increases greenhouse gas emissions by 2% globally, and 7% for Annex I countries. The price of certificates increases by 24% and total compli-ance costs of Annex I countries rise by 28%. Compliance costs increase the most for Japan (+58%) and the USA (+28%). China, India and Russia benefit from a global nuclear phase-out because revenues from higher trading volumes of certificates outweigh the costs of losing nuclear power as a mitigation option. Even for countries that face a relatively large increase in compliance costs, such as Japan, the nuclear phase-out implies a relatively small overall econom-ic burden. When trading of certificates is available only to countries that commit-ted to a second Kyoto period, the nuclear phase-out results in a larger increase in the compliance costs for the group of Annex I countries (but not for the EU and Australia). Results from sensitivity analyses suggest that our findings are fairly robust to alternative burden-sharing schemes and emission target levels.
