"" is an initiative undertaken by the members of the French Nuclear Energy Society (SFEN), the American Nuclear Society (ANS) and the European Nuclear Society (ENS). It brings together nuclear scientists from all parts of the globe, through the representation of 60 regional and national nuclear associations.

Nuclear for climate

  1. 1. The Paris Climate Conference (COP21)  France will host the 21st United Nations Climate Conference (COP21 Paris) on Nov30- Dec11, 2015, in Paris.  Will attend the 196 countries that have signed the UNFCCC since the Rio Summit.  The goal is to establish an agreement that is binding, applicable to all, and ambitious enough to limit global warming to 2°C  Preparation has already begun will the publication of the 5th report from the IPCC (Intergovernmental Panel on Climate Change)
  2. 2. What the climate experts say about climate change & what’s driving it (IPCC Working Group 1) Conclusions from climate experts:  The globally averaged combined land and ocean surface temperature data show a warming of 0.85 °C, over the period 1880-2012.  It is extremely likely (95% chance) that anthropogenic greenhouse gas emissions have been the dominant cause of the observed warming IPCC Workgroup 1 “The Physical Science Basis” A peer-review process of 9200 publications 260 authors and 600 contributors.
  3. 3. The need to tackle CO2 emissions in the power sector Increase in CO2 emissions from fossil fuels is the main contributor to climate change The power sector today represents 40% of total CO2 emissions
  4. 4. To limit the temperature increase below 2°C in 2050.. This is a massive global challenge that requires the use of all available low-carbon energy technologies. Today, it is about 30% Coal 41% Gas 22% Oil 5% Nuclear 11% Hydro 16% Other renewables 5% Other 32% 2013 world electricity generation by source Source: AIE-WEO 2014 ..at least 80% of the world’s electricity must be low-carbon by 2050.
  5. 5. The fight against climate change should not jeopardize development By 2050: the world’s population will be around 9.6 billion Today:  1.2 billion people do not have access to electricity  2.8 billion use wood or other biomass products for cooking and heating Major progress in energy efficiency will not be sufficient: the electricity demand is expected to double by 2050  Strong demand from non-OECD countries  Increased share of electricity in the overall energy mix Electricity demand and share of electricity (IEA)
  6. 6. The amount of CO2 emitted by nuclear energy is comparable to that of renewables The IPCC identifies three types of carbon-free electricity: renewables, nuclear and CCS (Carbon Capture & Storage).
  7. 7. We cannot wait for future technologies : they will contribute in proportion to their availability. It is urgent to use now all available low-carbon energy sources 70% of the carbon budget has been consumed Once released, CO2 remains in the atmosphere for a long time. Carbon budget: cumulative CO2 emissions that must not be exceeded if we are to contain average global warming to 2°C. 0 500 1000 1500 2000 2500 3000 3500 Carbon budget Remaining Since pre- industrial era Gt CO2 Source: IPCC
  8. 8. Nuclear energy is an available, low-carbon and efficient industrial solution, that has been proven efficient 438 nuclear reactors in operation, nuclear energy is available in 30 countries. Today, only 6 countries above 80% goal of low- carbon electricity, 4 of them have nuclear. Sweden 40% nuclear Switzerland 40% nuclear France 75% nuclear Brazil 2 nuclear reactors Since 1971 nuclear power has avoided the release of the equivalent of 2 years of CO2 emissions. By 2040, nuclear power should save the equivalent of 4 years of CO2 emissions.
  9. 9. "There is no credible way to climate stabilization that does not include an important role for nuclear energy….we cannot afford to turn our back on any technology". Open letter from environmentalists, Washington Post Most scenarios limiting the temperature increase to 2°C show a very significant contribution of nuclear energy  Gross nuclear capacity should double by 2050, from 400 GWe to 930 GWe.  Share of nuclear power in the global energy mix to increase from 11% to 17%.  Stability in OECD (long time operations), and strong growth in BRICs & Middle East: 70+ reactors being constructed WW Source: IEA technology roadmap Installed capacity by country
  10. 10. « Nuclear for Climate »: a grassroots initiative We proudly believe that nuclear energy is a key part of the solution #Nuclear4climate @Nuclear4climate It brings together the many professionals and scientists of the international nuclear community, coordinated via 60+ nuclear associations worldwide.
  11. 11. A joint statement in ICAPP, Nice, May 4, 2015 40 nuclear societies 50,000 scientists 37 countries “WE PROUDLY BELIEVE THAT NUCLEAR ENERGY IS A KEY PART OF THE SOLUTION IN THE FIGHT AGAINST CLIMATE CHANGE”
