The One Earth Climate Model (OECM) was established in 2017 by scientists from UTS ISF, the German Aerospace Center (DLR) and the University of Melbourne’s Climate & Energy College. Since then, it has been used to devise current carbon-reduction pathways for countries, regions and key industry sectors.
Now, the OECM has been applied to all 19 countries plus the EU27 region that form the G20 in 2023, to produce energy scenarios and fair carbon budgets for each country, as well as detailed carbon budgets for key industries in each country.
Detailed datasets for net-zero 1.5°C sectorial pathways that contain energy and emissions data to inform science-based decarbonisation targets are available here.
