13 April 2014, Berlin, Germany. Decision makers need accurate, recent and country-specific information to inform their decision. The International Panel on Climate Change (IPCC) presents its 2014 report on climate change mitigation in order to feed the decision making process in all countries. The report was adopted on 13 April 2014, in Berlin, Germany.
The report shows that global emissions of greenhouse gases have risen to unprecedented levels despite a growing number of policies to reduce climate change. Emissions grew more quickly between 2000 and 2010 than in each of the three previous decades. According to the Working Group III contribution to the IPCC’s Fifth Assessment Report, it would be possible, using a wide array of technological measures and changes in behaviour, to limit the increase in global mean temperature to two degrees Celsius above pre-industrial levels. However, only major institutional and technological change will give a better than even chance that global warming will not exceed this threshold. The report, entitled Climate Change 2014: Mitigation of Climate Change, is the third of three Working Group reports, which, along with a Synthesis Report due in October 2014, constitute the IPCC’s Fifth Assessment Report on climate change.
Since the last IPCC assessment report, published in 2007, a wealth of new knowledge about climate change mitigation has emerged. The authors of the new, fifth Working Group III report have included about 10,000 references to scientific literature in 16 chapters. Stabilizing greenhouse gas concentrations in the atmosphere requires emissions reductions from energy production and use, transport, buildings, industry, land use, and human settlements. Mitigation efforts in one sector determine the needs in others.
The Working Group III report consists of the Summary for Policymakers released today, a more detailed Technical Summary, the underlying 16 chapters, and three annexes. Working Group III chapter teams were formed by 235 authors and 38 review editors from 57 countries, and 180 experts provided additional input as contributing authors. More than 800 experts reviewed drafts of the report and submitted comments.
