How to Calculate Emission Reductions
Tracking emission reductions helps measure progress toward climate goals.
Formula
Reduction % = (Baseline - Current) / Baseline * 100
Absolute Reduction = Baseline - Current
Baseline is typically a reference year (e.g., 2019) against which progress is measured. Targets are often set as percentage reductions from that baseline.
Example Calculation
A company had 500 tons CO2e baseline, currently emits 350 tons, targeting 250 tons.
- 01Absolute reduction: 500 - 350 = 150 metric tons CO2e
- 02Reduction achieved: 150 / 500 * 100 = 30%
- 03Remaining to target: 350 - 250 = 100 metric tons CO2e
- 04Target reduction: (500 - 250) / 500 * 100 = 50%
