What lies behind this number
Global carbon-dioxide emissions from fossil fuels, cement production, international aviation and shipping.
How the source derives it
The Global Carbon Budget combines energy statistics, cement data and international transport; it published a preliminary estimate for 2025.
What one number cannot show
The figure excludes land-use change emissions such as deforestation. The preliminary annual estimate may change once full data become available.
Source value
The calculation uses the latest published annual value reported by Global Carbon Budget 2025 for 2025 (preliminary estimate).
How the value is used: The running number shows the share corresponding to time elapsed since the start of the calendar year.
