Estimate the offsets needed for a climate strategy after planned abatement, while applying a buffer for credit-delivery or permanence risk. The result separates operational reduction, base offset demand, buffer credits, and residual emissions.
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.
18,000 tCO2e with 30% abatement leaves 12,600. Covering 80% requires 10,080 base credits; a 10% buffer raises demand to 11,088 credits and the budget to $243,936 at $22 each.
Not in this calculator. Gross emissions and offsets remain separate so the residual balance is transparent.
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.
