Internal Carbon Price (ICP)
Internal Carbon Price (ICP): shadow price (₹/tCO₂e) entities apply to emissions in capex / supplier-selection decisions. Shadow vs internal-fee variants.
Definition
Internal Carbon Price (ICP) is a monetary value (typically ₹ per tCO₂e or USD per tCO₂e) that an entity voluntarily applies to its own GHG emissions for internal decision-making purposes — capital expenditure approvals, R&D project prioritisation, supplier selection, M&A target valuation, scenario stress-testing.
ICP is not the price the entity pays under a regulated compliance market (like CCTS or EU CBAM). It is an internally-set shadow price that creates a financial signal for behaviour change inside the organisation, before any real-world carbon-cost regulation forces the issue.
IFRS S2 requires entities to disclose ICP under its cross-industry metrics (Para 28-29) — including the price per tCO₂e applied, the scope of application, and how it influences decision-making. TCFD recommended the same disclosure structure before being absorbed into IFRS S2.
Three operational variants
Shadow price
The entity assigns a notional ₹/tCO₂e value but does not collect any actual cash internally. The shadow price is applied as an additional cost in business-case calculations for new investments — e.g., a new fossil-fuel boiler project is evaluated as if each tCO₂e of expected lifetime emissions has a financial cost of (project lifetime × annual emissions × shadow price), making the boiler look more expensive than a renewable alternative.
Most common variant globally; reflects strategic intent without changing cash flow.
Internal carbon fee
The entity actually collects ₹/tCO₂e from business units based on their emissions, pooling the revenue centrally to fund decarbonisation projects, renewable PPAs, REC purchases, or biodiversity / restoration projects.
Less common but increasingly used by entities serious about decarbonisation — particularly tech / IT services companies (Microsoft, Google) that levy an internal carbon fee on cloud / compute use and pool the proceeds for renewable energy procurement.
Implicit price
Some entities don’t formally label an ICP, but their decision-making rules effectively create one — e.g., a capex policy that requires all energy-intensive projects to achieve a 20% lower lifecycle emissions vs the previous-generation technology implicitly creates an emissions-cost penalty. The implicit price can be back-calculated from observed decision behaviour.
Typical price levels
Industry practice varies widely. Indicative ranges from CDP + World Bank reports:
- Lower-bound (compliance-anchored): ₹500-1,500 / tCO₂e (~USD 6-18) — anchored to current regulated market prices like CCTS or older PAT shadow values
- Mid-range: ₹1,500-5,000 / tCO₂e (~USD 18-60) — anchored to EU ETS recent average + voluntary carbon markets
- Upper-range: ₹5,000-10,000+ / tCO₂e (~USD 60-120+) — used by entities expecting future regulatory carbon-price escalation (e.g., EU ETS forward curves, US SEC climate-rule projections)
- Net-zero-aligned: ₹15,000+ / tCO₂e (~USD 180+) — IPCC + IEA models suggest a 1.5°C-aligned price of USD 130-250 / tCO₂e by 2030 in advanced economies; entities targeting full alignment use these higher values
Indian entities typically start at the lower-bound (current CCTS market range) + escalate via a documented price-curve to mid-range or higher by 2030-2035 to align with regulatory expectations.
How ICP feeds decision-making
Capex approval
New plant / equipment proposals are evaluated with the ICP-loaded emissions cost as part of total project cost. A project that’s cheaper on direct cost but emissions-heavier may flip to “rejected” once ICP is loaded.
R&D + product portfolio
Product-level emissions intensity comparisons use ICP to express GHG impact in financial terms — comparable to other product cost dimensions.
Supplier selection + procurement
Supplier comparison includes Scope 3 upstream emissions × ICP. A supplier with lower price but higher embedded emissions becomes evaluable on a like-for-like basis.
M&A target valuation
Target’s emissions profile × ICP becomes part of the EV adjustment — a high-emissions target is valued lower (or its emissions-reduction capex becomes part of the integration model).
Scenario stress-testing
Under various climate-policy scenarios (orderly transition, disorderly transition, hot-house world), the ICP is set to projected real prices to test portfolio resilience. This feeds the IFRS S2 scenario-analysis requirement.
ICP + IFRS S2 disclosure
IFRS S2 lists “internal carbon prices” as one of the seven cross-industry metrics required for disclosure (Para 29(f)). The disclosure must include:
- Price per tCO₂e applied
- How the price is set (anchored to compliance markets, IPCC trajectories, internal scenario analysis, etc.)
- Which decisions / processes the price is applied to (capex only, supplier selection, scenario testing, internal fee collection)
- How the price is reviewed + updated
For Indian listed entities filing both BRSR + a voluntary IFRS S2-aligned disclosure, the ICP narrative is typically a 2-3 paragraph section in the IFRS S2 disclosure that does not have a direct BRSR equivalent — BRSR currently does not have a specific ICP disclosure requirement but the narrative can be voluntarily added under Principle 6 Leadership Indicators.
ICP + CBAM / CCTS — strategic connection
For Indian exporters with CBAM exposure (steel, cement, aluminium, fertilisers), the ICP often anchors to future EU CBAM certificate prices — typically EU ETS forward curves (currently EUR 60-80 / tCO₂e in 2026, projected higher into the 2030s).
Applying an ICP at this level creates internal financial pressure to decarbonise BEFORE the CBAM definitive regime starts billing in 2026 — investments that would lose money at zero carbon price become positive-NPV when CBAM-aligned ICP is loaded.
For CCTS compliance-exposed entities, the ICP often anchors to projected CCTS prices (currently ₹200-800 / CCC) + the regulatory escalation expected as sectoral targets tighten.
Common ICP questions
Is ICP required by SEBI BRSR? Not as a mandatory disclosure currently. BRSR Principle 6 Leadership Indicators allow voluntary climate-strategy disclosure under which ICP is often reported. IFRS S2 does require ICP disclosure if applied — Indian entities filing voluntary IFRS S2-aligned disclosures must report it.
How is ICP different from a carbon tax? A carbon tax is a real, regulator-imposed cash outflow per tCO₂e. ICP is internally-set, voluntary, + (in shadow-price form) doesn’t involve actual cash movement. A carbon tax is exogenous (set by government); ICP is endogenous (set by the entity itself).
Should an Indian entity set an ICP if there’s no compliance market price to anchor to? CCTS is now operational; CCC market price provides an anchor. For entities not in CCTS-obligated sectors, EU ETS forward curves + IPCC 1.5°C-aligned price models (USD 130-250 / tCO₂e by 2030 per IEA / IPCC) are common reference points.
Does ICP affect financial statements? Shadow ICP does not — it influences decisions but doesn’t enter accounting books. Internal carbon fee MIGHT affect financial statements depending on accounting treatment (typically presented as an inter-entity transfer, not a P&L expense).
Is the ICP fixed or does it escalate over time? Most mature ICP programmes have a documented escalation curve — starting at current compliance price + escalating to a 2030 / 2035 target aligned with EU ETS forward curves or IPCC trajectories. The escalation curve is disclosed as part of the ICP methodology.
