The IIASA Energy, Climate, and Environment program (ECE) is compiling and hosting scenario ensembles for numerous integrated-assessment comparison projects, including the ensemble of quantitative pathways supporting the IPCC Special Report on Global Warming of 1.5° (SR15) and the soon-to-be-published contribution of Working Group 3 to the Sixth Assessment Report (AR6).

This community collects datasets and related work hosted by the IIASA ECE Scenario Services research theme on behalf of the Integrated Assessment Modeling Consortium (IAMC) as well as scientific work done in the research program.
