A variety of studies projecting future emission levels have been performed outside of the IPCC. Many scenarios generally confirm the intuitions of SRES. Most confirm that the costs and challenges of mitigation increase with the stringency of emissions targets. Many also find climate-action cases particularly challenging. For example, the EMF’s “Overview of the EMF 22 International Scenarios” found that, even assuming overshoot and immediate comprehensive international action, only eight of 14 models were successful in meeting a 450 ppm CO2-eq target by 2100. Large changes in required in energy and related systems were required to meet the target. No model the EMF’s study was able to produce emission levels under 450 ppm CO2-eq.
