Carbon Reduction Target Calculator
Calculate target emissions, required reductions and annual decarbonization rates from a baseline and reduction target.
Optional. Uses the same emissions unit selected above.
Required only if current emissions are entered.
Target Emissions
—
Maximum emissions at the target year after applying the selected reduction target.
Baseline emissions
—
Reduction target
—
Total reduction required
—
Target period
—
Linear annual reduction
—
Compound annual reduction rate
—
Current emissions
—
Reduction achieved
—
Target progress
—
Remaining reduction needed
—
Remaining years
—
Linear reduction needed per remaining year
—
Method:
Target emissions are calculated as:
Target Emissions =
Baseline Emissions ×
(1 − Reduction Target)
Total reduction required is:
Required Reduction =
Baseline Emissions − Target Emissions
For a simple linear pathway:
Annual Reduction =
Required Reduction ÷
(Target Year − Baseline Year)
The equivalent constant compound annual reduction rate is:
Annual Reduction Rate =
1 −
(Target Emissions ÷ Baseline Emissions)1 / Years
When current emissions are entered:
Reduction Achieved =
Baseline Emissions − Current Emissions
Target Progress =
Reduction Achieved ÷ Required Reduction × 100
Remaining Reduction =
Current Emissions − Target Emissions
This tool calculates an absolute emissions-reduction pathway. It does not determine whether a target meets a specific SBTi, sectoral, net-zero or regulatory methodology.
Real decarbonization pathways do not need to decline uniformly every year. The linear and compound rates are planning indicators for understanding the scale and pace of reduction required.
