What was done to it
Read the sheet 'Global Carbon Budget' of Global_Carbon_Budget_2025_v1.0.xlsx (Global Carbon Budget 2025 v1.0, ICOS object qSjPBsV1drZnYdH-yCJMmkGn): one row per year 1959–2024, in billion tonnes of carbon per year. Sinks are positive numbers in the sheet and stay positive here.

Checked the sheet's definition of the budget imbalance on every year: fossil emissions plus land-use change emissions, minus atmospheric growth, ocean sink, land sink and cement carbonation sink, equals the imbalance column (largest difference 3.3e-14 GtC/yr). This confirms that the fossil column is before the cement carbonation sink is subtracted.

For each year: fossil emissions (excluding carbonation) minus the cement carbonation sink, plus land-use change emissions.

Converted from billion tonnes of carbon to billion tonnes of carbon dioxide by multiplying by 3.664, the factor the sheet states ("multiply the numbers below by 3.664"), with exact decimal arithmetic on the stored values.
