Internal Carbon Pricing by Companies
Companies do not have to wait for governments. Many are implementing their own internal carbon prices to guide investment decisions, prepare for regulation, and drive emissions reductions. This lesson examines how corporate carbon pricing works.
What Is Internal Carbon Pricing?
Internal carbon pricing (ICP) is a self-imposed carbon cost that companies use internally for decision-making.
Key characteristics:
- Set by the company, not government
- Used for internal purposes, not compliance
- Can take various forms
- Typically not paid externally (though shadow prices influence decisions)
Over 2,000 companies worldwide use or plan to use internal carbon pricing. This includes many of the world's largest corporations, signaling that carbon costs are increasingly factored into business strategy.
Types of Internal Carbon Prices
Shadow prices:
A hypothetical carbon cost used in investment analysis and decision-making without actual money changing hands.
Internal fees:
Business units actually pay a carbon fee to a central fund based on their emissions. Money transfers within the company.
Implicit prices:
The cost of internal emissions reduction requirements, expressed as $/ton CO2.
| Type | How it works | Cash flow | Common use |
|---|---|---|---|
| Shadow price | Factor in investment analysis | None | Investment decisions |
| Internal fee | Business units pay to central fund | Internal transfer | Incentivizing reduction |
| Internal trading | Buy/sell within company | Internal transfer | Large conglomerates |
| Implicit price | Cost of compliance with internal targets | None (calculated) | Target-setting |
Why Companies Use Internal Carbon Pricing
Preparing for regulation:
Many companies expect carbon pricing to expand. Internal pricing helps them anticipate costs and prepare.
Risk management:
Understanding carbon exposure across operations helps identify and manage transition risks.
Investment guidance:
Carbon prices help compare investments by including future carbon costs in project economics.
Operational efficiency:
Pricing carbon creates incentives for business units to find reductions.
Stakeholder expectations:
Investors, customers, and employees increasingly expect climate action.
Microsoft's internal carbon fee:
Microsoft charges business units $15 per ton of CO2 equivalent for their emissions. This fee:
- Creates incentive for emissions reduction
- Generates an internal fund
- Funds carbon removal purchases
- Has grown from $8/ton initially to $15/ton
Microsoft reports the fee has driven significant efficiency improvements and helped fund carbon removal investments.
Setting the Price Level
Companies set internal carbon prices using various approaches:
Current compliance costs:
Based on existing carbon prices where the company operates (e.g., EU ETS price).
Expected future prices:
Based on projections of where carbon prices are heading.
Social cost of carbon:
Based on estimated damages from emissions.
Abatement cost:
Based on what it actually costs the company to reduce emissions.
Target alignment:
Price level needed to meet internal climate targets.
CDP surveys reveal internal carbon price levels vary widely:
Distribution:
- Under $10/ton: ~15% of companies
- $10-50/ton: ~45% of companies
- $50-100/ton: ~25% of companies
- Over $100/ton: ~15% of companies
Sector patterns:
- Energy companies: Often higher prices (exposure to carbon transition)
- Financial services: Often shadow prices for investment decisions
- Manufacturing: Mix of shadow prices and internal fees
- Technology: Often internal fees funding climate initiatives
Geographic patterns:
- European companies: Often aligned with EU ETS prices
- US companies: More varied, often lower
- Asian companies: Increasingly adopting
Trend: Internal carbon prices have been rising, reflecting increased climate ambition and expectations of higher future prices.
Implementation Approaches
Centralized vs decentralized:
Centralized: Corporate sets the price; business units apply it.
Decentralized: Business units may set different prices based on local conditions.
Scope:
Scope 1: Direct emissions from owned operations.
Scope 2: Emissions from purchased energy.
Scope 3: Value chain emissions (harder to price internally).
Applications:
- Capital investment decisions
- Operating budgets
- Procurement choices
- Product development
- Merger and acquisition analysis
Case Studies
Shell:
Uses a $40/ton internal carbon price for investment decisions on major projects. This has influenced investment portfolio toward lower-carbon options.
Unilever:
Applies an internal carbon price to procurement decisions, encouraging suppliers to reduce emissions.
Delta Airlines:
Invests in carbon offsets using an internal carbon pricing framework, aiming for carbon neutrality.
Mahindra Group (India):
One of the first Indian conglomerates to implement internal carbon pricing, applying it across diverse businesses.
Challenges and Limitations
Price level uncertainty:
Setting the "right" price is difficult when future regulations are uncertain.
Behavioral response:
Shadow prices may not change behavior as effectively as actual fees.
Scope 3 complexity:
Pricing value chain emissions is methodologically challenging.
Competitive concerns:
If competitors do not price carbon, internal pricing may create cost disadvantage.
Measurement accuracy:
Internal pricing requires accurate emissions data across operations.
Benefits Realized
Companies report internal carbon pricing delivers:
Investment shifts: Capital flows toward lower-carbon projects.
Efficiency gains: Business units find reductions when they face costs.
Regulatory readiness: Better prepared when external carbon pricing is implemented.
Risk identification: Carbon exposure becomes visible and manageable.
Innovation incentives: Creates demand for low-carbon solutions.
Internal carbon pricing is like companies setting their own speed limits before traffic laws require them. They may not face penalties yet, but they are building the habits and systems needed for a carbon-constrained future.
Looking Ahead
Internal carbon pricing is one way companies prepare for carbon constraints. The final lesson in this module examines how carbon pricing systems should be evaluated, reviewed, and continuously improved.
