What carbon pricing and carbon markets analysis actually involves

Carbon pricing puts a monetary cost on greenhouse gas emissions, either through a tax (carbon levy) or a cap-and-trade system (emissions trading scheme). Carbon markets are the platforms where emissions allowances and credits are bought and sold. For corporate teams, the analytical work involves assessing exposure to existing and emerging carbon pricing mechanisms, modelling the financial impact of different carbon price scenarios on operations and supply chains, and making informed decisions about participation in voluntary carbon markets. As carbon prices rise and coverage expands, this is becoming a material financial planning issue rather than a compliance footnote.

Why it's harder in practice than it looks

Carbon price coverage varies significantly by jurisdiction

The EU ETS, UK ETS, CBAM, and various national carbon taxes apply to different sectors, fuels and activity types. A company operating across multiple geographies faces a patchwork of obligations that interact in non-obvious ways, particularly as border adjustment mechanisms extend the reach of domestic pricing to imported goods.

Scenario modelling requires contested assumptions

Carbon price forecasts vary enormously between energy agencies, investment banks and academic modellers. Applying an internal carbon price for investment appraisal requires a defensible methodology for choosing the price trajectory used, and companies that use low or static price assumptions will systematically underestimate the cost of carbon in long-lived asset decisions.

The EU Carbon Border Adjustment Mechanism creates new supply chain obligations

CBAM, phasing in from 2026, requires EU importers of covered goods (cement, steel, aluminium, fertilisers, electricity, and hydrogen) to account for the carbon price paid in the country of production. This creates compliance obligations that cascade from regulated companies to their suppliers and procurement teams in affected sectors.

Voluntary carbon markets are under structural reform

The voluntary carbon market is undergoing significant credibility reform following integrity concerns, with new quality standards, tighter methodology requirements, and greater scrutiny of offset claims. Companies that have not updated their understanding of these changes risk purchasing credits that no longer meet market or regulatory expectations.

What good looks like

A well-prepared carbon markets and pricing strategy includes a regulatory exposure map covering all jurisdictions where the business operates or procures, an internal carbon price applied to investment appraisal decisions with a documented rationale, a voluntary carbon market strategy aligned with SBTi requirements, and monitoring processes for CBAM and other emerging pricing mechanisms. The outputs feed directly into financial planning, procurement policy and investor risk disclosures.

When to bring in external support

Carbon pricing analysis spans regulatory intelligence, financial modelling and carbon market dynamics. Leafr's network includes carbon pricing and markets specialists who provide scenario modelling, regulatory exposure assessments and voluntary market strategy support for corporate finance and sustainability teams navigating this increasingly material issue.

Frequently asked questions

What is an emissions trading scheme?

An emissions trading scheme (ETS) is a market-based mechanism that sets a cap on total greenhouse gas emissions from covered sectors and issues allowances equal to that cap. Companies must hold allowances to cover their emissions; those with surplus can sell to those with a deficit. The price of allowances fluctuates based on supply and demand, creating a financial incentive to reduce emissions.

What is an internal carbon price and should all companies have one?

An internal carbon price is a financial value applied to greenhouse gas emissions within a company's own investment and procurement decision-making. It acts as a shadow cost that reflects potential future regulatory carbon pricing. Large companies with significant emissions or capital expenditure programmes benefit substantially from applying one, as it ensures long-lived investment decisions are not made on the basis of artificially low energy and carbon cost assumptions.

What is CBAM and which companies are affected?

The EU Carbon Border Adjustment Mechanism requires EU importers of certain carbon-intensive goods to purchase CBAM certificates reflecting the carbon price that would have been paid had those goods been produced under the EU ETS. It applies to cement, steel, aluminium, fertilisers, electricity and hydrogen, with full obligations from 2026. Non-EU companies supplying these goods to EU customers need to report embedded emissions and may need to price in CBAM costs.

How should a company choose an internal carbon price?

Common approaches include using a regulatory carbon price (the price under applicable ETS or carbon tax), a social cost of carbon estimate, or a scenario-based price aligned with 1.5C or 2C pathways from bodies such as the IEA or NGFS. The choice should be documented, reviewed annually, and high enough to genuinely change investment decisions rather than simply comply with a policy requirement.

Are voluntary carbon market prices rising?

Voluntary carbon market prices vary significantly by credit type and quality. High-quality carbon removal credits (from DAC or biochar, for example) have seen price increases, while lower-quality avoidance credits have faced downward pressure following integrity concerns. The direction of market reform is toward fewer, higher-quality credits at higher prices, with low-quality credits becoming increasingly difficult to use in credible corporate claims.
