Supply Chain Carbon Transition Risk Calculator

Estimate financial exposure from a higher future carbon price across supply-chain emissions. The result combines the emissions exposed to pricing, the expected price increase, and the share of that increase suppliers may pass through, helping procurement teams compare transition scenarios.

How to use this calculator

  1. Enter the activity, emissions, or cost values for the reporting period.
  2. Use consistent metric-tonne CO₂e units and prices.
  3. Select Calculate to update the estimate.
  4. Review the supporting results before using the figure in a plan or budget.

Formula

Incremental transition exposure = Emissions × (1 − Reduction %) × Covered share × (Future price − Current price) × Pass-through share

What the result means

The main result estimates incremental annual cost exposure caused by the entered price increase after planned emissions reductions. It is a scenario value rather than a probability-weighted forecast.

The calculator addresses carbon-price transition risk only. It does not quantify demand changes, stranded assets, technology shifts, litigation, or physical climate risk.

Example calculation

For 11,000 t, 70% coverage, a price increase from $35 to $90, 60% pass-through, and 10% reduction, incremental exposure is $228,690.

Tips for better results

  • Keep the reporting boundary and period consistent across every input.
  • Use supplier-specific or verified factors when available.
  • Document whether figures are measured, estimated, or modeled.
  • Run a low and high scenario for uncertain prices or factors.
  • Reduce emissions before relying on offsets for residual emissions.

Frequently asked questions

What does supplier cost pass-through mean?

It is the portion of a supplier's modeled carbon-price cost assumed to appear in the buyer's prices.

Can the future carbon price be lower than the current price?

Yes, but the result will show a negative change, indicating lower modeled exposure rather than added risk.

Why is expected emissions reduction included?

Reducing emissions before the future price applies lowers the footprint exposed to the price change.

Is this a complete climate transition risk assessment?

No. It isolates one financial pathway: changes in carbon pricing passed through the supply chain.

How should I use the avoided-risk figure?

Use it to compare the carbon-price exposure with and without the entered emissions reduction, not as guaranteed savings.
