How this measure is built
- Definition
- Total carbon dioxide emitted worldwide in the year from fossil fuel use and industrial processes such as cement production, as assessed by the Global Carbon Budget.
- Measure
- One slice of CO2 emissions ( form: level ) . Total volume of carbon dioxide emissions released into the atmosphere. Region and period are columns on every record, not slices.
- Limitations
- 1 figure is a projection, drawn dashed and labelled in the table. Values are shown as published; StatOrigin does not revise, fill gaps or convert currencies.
- Verification
- Each value, unit, period and place was checked against its quote before publication. See the methodology and the corrections process.
