Are carbon allowances the same as carbon credits?

Carbon allowances in the EU ETS are regulated instruments for capping emissions, while carbon credits are voluntary offsets from various projects. The EU ETS is a much larger market with unique, standardized allowances, whereas carbon credits vary in price and verification. Both contribute to carbon accounting and emissions reduction, but operate under different frameworks.

Carbon allowances and carbon credits are fundamentally different. European Union Allowances (EUAs) operate in a massive, regulated compliance market. In contrast, carbon credits can take all sorts of shapes and sizes - they belong to a voluntary market and are often used for corporate carbon accounting purposes.

Carbon Allowances: The Backbone of Emissions Trading Systems (ETS)

The definition of a carbon allowance

Carbon allowances are the financial instrument from the Emissions Trading Systems (ETS), a regulated market designed to cap and reduce emissions. Every EUA represents the right to emit one tonne of CO2. The European Commission issues these allowances, and their total number is capped and gradually decreased to limit overall emissions.

A highly regulated market

The EU ETS is a compliance market. Once an installation falls under its scope, it must account for its carbon emissions and purchase and surrender a corresponding number of EUAs each year. Failure to do so results in a fee of EUR 100 plus the cost of the carbon allowances in question.

The singular nature of carbon allowances 

Carbon allowances issued by the European Commission are unique physical contracts and are kept in a dedicated carbon registry within the EU database. For compliance installations, there is no choice between various products within the EU ETS; there is only one type of EUA with a uniform price at a given point in time.

The massive size of the carbon allowance market 

The EU ETS is the largest carbon allowance market - 2023, the market was valued at approximately $835 billion, compared to $105.2 billion for other carbon markets worldwide and between $984 million and $1.312 billion for voluntary carbon markets.

Carbon Credits: Voluntary Market for Offsetting Emissions

The definition of a carbon credit

Carbon credits or carbon offsets, are certificates representing the reduction or removal of one tonne of CO2 from the atmosphere. These credits can be generated by various projects aimed at reducing or capturing emissions, such as reforestation or methane capture.

A voluntary participation 

The carbon credit market is voluntary. Companies and individuals can purchase credits to offset their emissions, often as part of corporate social responsibility initiatives or personal climate commitments.

There is no unique standard for carbon credits 

Carbon credits can be generated through various activities aiming at reducing GHG emissions or increasing carbon sequestration. These projects might involve developing renewable energy, capturing high-potency gases, avoiding deforestation…

After their issuance, a verification process is needed to ensure these credits' legitimacy. Project developers provide evidence of their carbon reduction efforts (through monitoring data and reports) which is then reviewed by a third-party verifier.

The carbon credit price variability 

The cost of carbon credits varies widely depending on the type and location of the project. They can range from a few dollars per tonne to higher prices for projects that are estimated to be better verified or impactful. In 2023, the average price of voluntary carbon credits ranged from $6 to $8 per tonne.

Carbon allowances, as part of the regulated ETS, operate in a large-scale, transparent, and economically driven approach to reducing emissions. Carbon credits, issued through voluntary carbon offset or removal projects, can contribute to an individual’s or corporation’s carbon accounting objectives.

UKAs and EUAs: Why Hold Both When You're Already Invested in European Carbon

If you're already invested in European EUAs, do you need to bother with UK UKAs? Short answer: yes. Long answer: the two markets are correlated at around 80% over time, but that correlation hides distinct dynamics (political, industrial, calendar-based) that make UKAs both linked and differentiated from EUAs. That's precisely what makes the combination interesting: an EUA core for liquidity and depth, a UKA satellite for political catch-up and the associated risk premium. Here's why.

What is the Climate Impact of a UKA? One Tonne of CO₂ Pulled Off the Market, Measured and Verifiable

Holding a UKA does something simple and radical: it takes one right-to-emit tonne of CO₂ off the UK market. Not an offset, not a voluntary credit, not a tree-planting promise. A regulated allowance, accounted for by the State, that exits the system the moment a non-compliance investor holds it. It's what we call an additional climate action: measurable, verifiable, legally framed. Here's how it works, and why this impact is one of the most robust in today's climate-finance landscape.

The UKA-EUA Convergence Play: Anatomy of a Catch-Up in Motion

May 2025, London summit: Keir Starmer and Ursula von der Leyen formally state their intention to link the UK ETS to the European system. A new term has been circulating among carbon analysts ever since: the Convergence Play. The mechanic is simple: UKAs trade today around 20% below EUAs, a discount that has already partially closed since May 2025. The residual mechanical upside is around +20 to +25%. Here's how it works, why it's happening now, and what the Swiss-EU precedent teaches us.
