IIASA researchers Keywan Riahi and Fabian Wagner contributed to the report from the United Nations Environment Program (UNEP), which estimates the “emission gap,” or the difference between the level of greenhouse gas emissions projected for 2020, and the emissions level that is consistent with reaching international goals for climate, such as limiting global temperature rise to 2° or 1.5° Celsius. The report shows that without action, carbon dioxide emissions could rise to 58 gigatons (GtCO2) per year by 2020.
Wagner worked on Chapter 2, estimating current and future emissions and emission intensities. Riahi worked on Chapter 3, which updates the estimate emissions gap presented in UNEP’s 2011 report by analyzing emissions scenarios.
