CEDS

The Community Emissions Data System (CEDS) produces consistent estimates of global air emissions species over the industrial era (1750 - present). The system is written in R and uses open-source data (with the exception of the IEA energy statistics which must be purchased from IEA). CEDS is publicly available through an Open Source License.

April 2021 Release: April 21, 2021 (v_2021_04_21)

This release updates emissions for four isos: Australia, Canada, South Korea, and Taiwan as shown in Figure S9 here. Global trends are similar to the v_2021_02_05 release. Global gridded emission data have also been produced with updated spatial distributions for most sectors.

Feb 2021 Release: February 05, 2021 (v_2021_02_05)

This data and code release extends the emissions time series to 2019 and updates driver and emissions data throughout. This version builds on the extension of the CEDS system to 2017 described in McDuffie et al. 2020. Major features:

  • Emissions estimates to 2019
  • Updated default data from GAINS and EDGAR
  • Updates to country inventories used for scaling
  • Improved BC/OC emission time series
  • Improved consistency over time
  • Updated code and driver data

For details on this release see:

We encourage comments on this data. The best way to comment on the data is through the CEDS Issues page.

Gridded data corresponding to this release is in production and will be released shortly.

A journal paper describing this dataset is in preparation. A notice will be updated here and sent to the CEDS listserv when this is available.


Documentation of CEDS assumptions and system operation, including a user guide, are available at the CEDS project wiki and in the journal papers noted below.

Current issues with the data or system are documented in the CEDS Issues system in this GitHub repository. Users can submit issues using this system. These can include anomalies found in either the aggregate or gridded emissions data. Please use an appropriate tag for any submitted issues. Note that by default only unresolved issues are shown. All issues, including resolved issues, can be viewed by removing the "is:open" filter. Issues relevant for CMIP6 data releases are tagged with a “CMIP6” label (note that issues will be closed when resolved in subsequent CEDS data releases, but are still available for viewing.)

Further information can also be found at the project web site, including a CMIP6 page that provides details for obtaining gridded emission datasets produced by this project for use in CMIP6. You can also sign up for data release announcements from the CEDSinfo listserv following the instructions on the project web site.

If you plan to use the CEDS data system for a research project you are encouraged to contact Steve Smith so that we can coordinate with any on-going work on the CEDS system and make sure we are not duplicating effort. CEDS is research software, and we will be happy to help and make sure that you are able to make the best possible use of this system.

Users should use the most recent version of this repository, which will include maintenance updates to address documentation or usability issues. Major changes that alter emission estimates or system structure and use will be noted in the release notes.

CEDS has only been possible through the participation of many collaborators. Our collaboration policy is that collaborators who contribute unpublished data used in CEDS updates will be included as co-authors on the journal paper that describes the next CEDS major release. We particularly encourage contributions of updated emission information from countries or sectors not well represented in the data currently used in CEDS.
