Calculation method & limits
Removal volume = total volume × removal allocation / 100. Reduction volume = total volume − removal volume. Credit spend = reduction volume × reduction price + removal volume × removal price. Fees = credit spend × fee percentage / 100. Total budget = credit spend + fees.
Calculations retain decimal volumes and display up to two decimal places. Fractional units are planning arithmetic; actual purchases and issuance rules may differ. Taxes, FX, delivery risk and other costs are excluded. The mix is an editable scenario, not a recommended portfolio. There is no inference about carbon neutrality or progress toward a target.
