What you should know about this indicator

  • This data is based on territorial emissions, which do not account for emissions embedded in traded goods.
  • Emissions from international aviation and shipping are not included in any country or region's emissions. They are only included in the global total emissions.

Sources and processing

This data is based on the following sources

The Global Carbon Budget was founded by the Global Carbon Project (GCP) international science team to track the trends in global carbon emissions and sinks and is a key measure of progress towards the goals of the Paris Agreement. It's widely recognized as the most comprehensive report of its kind.

The GCP has been publishing estimates of global and national fossil CO2 emissions since 2001. In the first instance these were simple re-publications of data from another source, but over subsequent years refinements have been made in response to feedback and identification of inaccuracies.

How we process data at Our World in Data

All data and visualizations on Our World in Data rely on data sourced from one or several original data providers. Preparing this original data involves several processing steps. Depending on the data, this can include standardizing country names and world region definitions, converting units, calculating derived indicators such as per capita measures, as well as adding or adapting metadata such as the name or the description given to an indicator.

At the link below you can find a detailed description of the structure of our data pipeline, including links to all the code used to prepare data across Our World in Data.

Notes on our processing step for this indicator
  • Data on global emissions has been converted from tonnes of carbon to tonnes of carbon dioxide (CO₂) using a conversion factor of 3.664.
  • Emissions from the Kuwaiti oil fires in 1991 have been included as part of Kuwait's emissions for that year.
  • Country's share of the global population is calculated using our population dataset, based on different sources.
  • Each country's share of global CO₂ emissions from flaring has been calculated using global CO₂ emissions from flaring provided in the Global Carbon Budget dataset.
