ODIAC Fossil Fuel CO2 Emissions Dataset
Click Here to Download
The Open-Data Inventory for Anthropogenic Carbon dioxide (ODIAC) is a high-spatial resolution global emission data product of CO2 emissions from fossil fuel combustion (Oda and Maksyutov, 2011). In 2009, the first version of ODIAC was developed by Drs. Tomohiro Oda (now at the Universities Space Research Association, USRA) and Shamil Maksyutov under the Greenhouse gases Observing SATellite (GOSAT) project at the National Institute for Environmental Studies (NIES) in Japan.
ODIAC pioneered the combined use of space-based nighttime light data and individual power plant emission/location profiles to estimate the global spatial extent of fossil fuel CO2 emissions. With the innovative emission modeling approach, ODIAC achieved the fine picture of global fossil fuel CO2 emissions at a 1x1km, possibly the most beautiful global picture of man-made emissions. As seen in a number of publications in the literature, the ODIAC emission data product has been widely used by the international research community for a variety of research applications (e.g. CO2 flux inversion, urban emission estimation and observing system design experiments).
Since its original publication in 2011, the ODIAC team has made numerous modifications to the ODIAC emission model, and updated and upgraded the emission data product (see Oda et al. 2018). On this data site, the latest version of the ODIAC emission data product (ODIAC2022, 2001-2021) is available for download. Previous versions of the emission data product, including the original version (ODIAC v1.7, 1980-2007), as published by Oda and Maksyutov (2011), are also archived, but only for reference purposes. The team encourages data users to use the latest, updated emission product (currently, ODIAC2022) for their research applications, as the emission estimates included in previous versions of the data product are considered to be outdated once new product becomes available. The details of the ODIAC emission model/data product are described elsewhere (Oda and Maksyutov, 2011; Oda et al., 2018).
