Consumption-based CO₂ emissions

What you should know about this indicator
- Consumption-based emissions attribute the emissions generated in the production of goods and services according to where they were consumed, rather than where they were produced.
- The data is calculated by adjusting 'production-based' emissions (emissions produced domestically) for trade: Consumption-based emissions equals production-based emissions, minus emissions embedded in exports, plus emissions embedded in imports.
- If a country's consumption-based emissions are higher than its production emissions it is a net importer of carbon dioxide. If its consumption-based emissions are lower, then it is a net exporter.
- Consumption-based emissions are not available for all countries because not all countries have sufficient, high-quality trade data. But those without complete data are a small fraction (3%) of the global total.
- This data measures carbon dioxide (CO₂) emissions from fossil fuels and industry and does not include emissions from land use change, deforestation, soils, or vegetation.
- Emissions from international aviation and shipping are not included in the data for any individual country or region. They are only counted in the global total.

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
- Global emissions are converted from tonnes of carbon to tonnes of carbon dioxide (CO₂) using a factor of 3.664. This is the conversion factor recommended by the Global Carbon Project. It reflects that one tonne of carbon, when fully oxidized, forms 3.664 tonnes of CO₂, based on the relative molecular weights of carbon and oxygen in CO₂.
- Emissions from the 1991 Kuwaiti oil fires are included in Kuwait's emissions for that year.
