How this number is made
- Source
- GCP, Fossil fuel CO2 emissions hit record high in 2025 (13 Nov 2025)
“The 2025 Global Carbon Budget projects 38.1 billion tonnes of fossil carbon dioxide (CO2) emissions this year.”
- Step 01
Take GCP’s figure for 2025: 38.1 billion tonnes (a projection).
- Step 02
Spread it evenly over a year of 31,557,600 seconds (365.25 days): about 1,207 tonnes of CO₂ per second.
- Step 03
Count from 00:00 UTC on 1 January of the current year, so the number resets every New Year.
- On screen
- The result of those steps, recomputed four times a second in your browser. Nothing on this page is fetched live from the publisher.
- Why this can't be exact
- Real activity is not spread evenly: it clusters in working hours, weekdays and seasons, so the count runs ahead or behind the true figure at any given moment. The annual figure is GCP’s projection; the counter moves to the published actual once it is released. Digits beyond the first two or three are the model ticking, not extra precision.
