IAMC 1.5°C Scenario Explorer

The “IAMC 1.5°C Scenario Explorer ” presents an ensemble of quantitative, model-based climate change mitigation pathways underpinning the Special Report on Global Warming of 1.5°C (SR15) by the IPCC published in 2018. The ensemble was also used and extended in the IPCC’s Special Report on Climate Change and Land (SRCCL, 2019).

The scenario ensemble contains more than 400 emissions pathways with underlying socio-economic development, energy system transformations and land use change until the end of the century, submitted by over a dozen research teams from around the world. It was compiled as part of efforts to support the SR15. The IAMC facilitated a coordinated and systematic community effort by inviting modeling teams to submit their available 1.5°C and related scenarios to a curated database. The compilation and assessment of the scenario ensemble was conducted by authors of the IPCC SR15
