Year-wise Emissions Pathway
Annual projected emissions in tCO₂e
| Year | Scope 1 | Scope 2 | Scope 3 | Total |
|---|
How it works: The calculator applies the selected annual reduction rate to the remaining emissions of each scope every year.
Projected Emissions =
Baseline Emissions ×
(1 − Annual Reduction Rate)Years
Scope 1, Scope 2 and Scope 3 are calculated independently and then added to determine total annual emissions.
This calculator models an emissions-reduction trajectory and does not determine or certify net-zero status. Actual net-zero assessment may require recognised target-setting criteria, organisational and value-chain boundaries, sector-specific pathways, and treatment of residual emissions.
