Estimate the quantity and budget of carbon offsets needed after applying an internal carbon price and a chosen offset coverage policy. The tool keeps gross emissions, planned reductions, residual emissions, and offsets separate so teams can see what operational reductions achieve before purchasing credits.
The main result is the number of offset credits required for the selected coverage policy. Secondary results show the purchase budget and emissions left uncovered.
Offsets do not replace direct emissions reductions. Credit quality, additionality, permanence, and retirement rules require separate due diligence.
For 12,000 tCO2e, a 20% operational cut leaves 9,600 tCO2e. Covering 75% requires 7,200 credits and costs $129,600 at $18 per credit.
Yes. The calculator converts the selected residual emissions into tonnes to offset, then estimates the budget at your entered offset price.
Use metric tonnes of carbon dioxide equivalent (tCO2e) consistently across all emissions fields.
Zero is accepted where it is meaningful. The calculator blocks negative values and any input that would make the selected scenario invalid.
Run conservative, central, and optimistic cases by changing the uncertain inputs and compare the resulting exposure.
It is a planning estimate only. Apply the required reporting standard, boundaries, factors, and assurance process separately.
