WEO-2021 Free Dataset includes world aggregated data for all scenarios (SDS, APS, STEPS, NZE) and selected data for key regions and countries for 2030 and 2050, as well as historical data (2010, 2019, 2020). Access to this dataset is free of charge for non-commercial usage. 

WEO-2021 Extended Dataset includes more detailed information at regional and country-level for SDS, APS, STEPS (including detailed energy balance, electrical capacity, electricity generation, CO2 emission by region, etc..) across projected years (2030, 2035, 2040, 2045, 2050) as well as historical data (2010, 2015, 2019, 2020). It includes the same global data from the NZE available in the free dataset. It also includes WEO-2021 chapter figures data.
