Each year the Carbon Dioxide Information Analysis Center (CDIAC) generates estimates of carbon releases from fossil-fuel consumption and cement production. Emissions from fossil-fuel burning represent the largest anthropogenic source of carbon to the atmosphere and are an important contributor to elevated atmospheric CO2 levels. CDIAC produces annual fossil-fuel CO2 emission time series at global and national scales and these time series serve as building blocks for other data products including gridded (1 x 1) emission time series. Details regarding the methods used to produce these time series and data products may be found on the CDIAC website.

This new interface allows users to query, visualize, and download the latest CDIAC fossil-fuel CO2 emission estimates. In the future, additional CDIAC fossil-fuel related data products (e.g., global isotopic signatures) and enhanced functionality will be incorporated into the interface so please provide feedback and suggestions for improvement.
