Carbon price exposure calculator
For CFOs and risk teams. Enter your Scope 1 and 2 emissions and the share a carbon price would cover. The tool shows the annual cost under each price scenario and, if you add EBITDA, the share of EBITDA it would take. Prices are editable. Use it for scenario analysis under IFRS S2, not as a forecast.
