Citing our results

  • We ask that scientific work that relies heavily on CarbonTracker products is discussed with us before publication, to ensure proper representation of our work and co-authorship if appropriate.
  • Please use "CT2015" as the shorthand to refer to our product, not "CT". This identifies both the product and the release version.
  • It is crucial to identify the version of the product you are using (e.g. "CT2015").
  • Note that the product is called "CarbonTracker" without a space character, not "Carbon ␣ Tracker".
  • Please cite as: "Peters et al. (2007), with updates documented at http://carbontracker.noaa.gov."
  • Please include our suggested acknowledgment text in your acknowledgments section.
  • Boilerplate model description text provided upon request.
