Voluntary carbon markets: how they work and how they’re priced

2022 is likely to be known as the year that carbon finance became an issue of discussion in many industries.

In the 2022 class of new participants in carbon markets that are voluntary, major oil and gas companies as well as hedge funds and banks were deemed to be the most active participants who were determined to take positions in the market. However, as the year progressed and the year progressed, other industries have joined the market in line with their commitments to reduce carbon footprints.

Numerous political entities such as the EU as well as in the UK and the State of California have carbon markets that cover specific industry segments and gases. They are an essential part of the efforts to achieve the Paris Agreement target of limiting global warming up to 2 degrees Celsius above preindustrial levels (with an even more ambitious goal of achieving 1.5 C). 1.5 C increase), even although some of these markets are older than those of the Paris commitments.

However, other industries have also adopted the same principles as compliance programs and have committed to reduce the greenhouse gases they emit (GHG) through participation in carbon markets on a voluntary basis.

Voluntary carbon markets permit producers of carbon to reduce their inevitable emissions by buying carbon credits generated through projects aimed at eliminating or cutting down GHG out of the atmosphere.

Each credit, which is equivalent to one metric tons of avoided, reduced or eliminated CO2 or comparable GHG – is able to be utilized by a business or an individual to pay for the emissions of one metric ton of CO2 or similar gases. If a credit is utilized to offset the emission of gases it is considered an offset. It is transferred into a registry for retired credits, also known as retirements, and is no longer tradeable.

Businesses can take part in trading carbon credits in a single transaction or as part of an overall industry-wide plan, like CORSIA, the Carbon Offsetting and Reduction Scheme for International Aviation, which was created by the aviation industry to reduce carbon dioxide emissions. Airlines that are part of international airlines participating in CORSIA have committed to offset all the CO2 emissions they generate over a base level of 2019.

Although compliance markets are currently restricted to certain regions, carbon credits that are voluntary are more flexible, and are not governed by the boundaries established by nation states or political unions. They are also able to be used by any industry instead of just a handful of industries.

The Taskforce for scaling Voluntary Carbon Markets is a project of the Institute of International Finance with assistance from McKinsey, estimates that the carbon market credits could reach upwards 50 billion dollars as early as 2030.
The participants

Five major players form the carbon market’s engine.


Project developers are the upstream portion of market. They create the projects that issue carbon credits that can be a range of industrial-scale projects of a large scale, like an hydro plant with a large volume as well as smaller, community-based ones such as cooking stoves that are clean.

There are initiatives aimed at eliminate or reduce the direct emissions that result from industrial processes , such as emission management fugitive, ozone capture or the destruction of substances that deplete ozone or treatment of wastewater. Natural-based projects comprise REDD+ (avoided deforestation) and soil sequestration, as well as the afforestation. Other kinds include carbon capture using technology like direct air capture, and new categories are constantly added to the list.

Every credit comes with a distinct vintage that is the year it was first issued, as well as the specific date of delivery that is the date when the credit will become available for sale. Alongside their primary goal of preventing or eliminating GHGs from the air Credit projects may create additional benefits and assist in achieving certain of the United Nations’ Sustainable Development Goals (SDGs). They could, for instance, aid in improving the welfare of the population in the area, improved drinking water, and the reduction of inequality in the economy.

End Buyers

The market downstream is comprised of buyers who are end-users: businesses or even consumers who have pledged to offset a portion or all or all of their GHG emissions.

The first buyers of carbon credits was tech firms like Apple and Google airlines, as well as oil and gas companies, however, more industries such as finance are entering the market in the process of setting their own net-zero goals or seek a way to protect themselves from the financial risks associated with an energy revolution.

Implementation of Article 6 of the Paris Agreement on the 13th of November at the UN Climate Conference, or COP26 in Glasgow established the guidelines for a crediting system that can be utilized by 193 of the parties to the Paris agreement to meet their targets for emission reductions or contributions that are determined by the national government. Implementation of the Article 6 allows nations to purchase voluntary carbon credits as provided that Article 6 rules are respected.


To connect demand and supply There are brokers as well as retail traders, as in other commodities markets. Retail traders buy large quantities of credits directly from the provider and then bundle them into portfolios, which range between hundreds and thousands equivalent tonnes of CO2 and then sell the bundles to buyers usually with a commission.

Although the majority of transactions are happening now through private conversations or over-the-counter transactions, some exchanges are also forming. The two largest carbon credits exchanges in the present are NY-based Xpansiv CBL and Singapore based AirCarbon Exchange (ACX).

Exchanges have been working to streamline and speed up the trading of carbon credits, which are characterized by a an extremely complex structure due to the large number of variables that affect their value by introducing standard productsthat ensure certain basic requirements are met.

For instance, both Expansiv CBL as well as ACX have created standard products for natural-based credits CBL’s Nature-based global Emission Offset (N-GEO), as well as ACX’s Global Nature Token. ACX Global Nature Token.

Credit transactions under these labels is certain to be regulated by specific characteristics like the kind of project that is the basis, a relatively recent date, and a certificate from a limited set of standards.

Exchanges’ standard products – particularly those that allow forward delivery – are popular with traders and financial institutions looking to purchase and hold to prepare for the rising demand for carbon credit.

End buyers who need to buy credits in order to reduce their carbon emissions are more likely to choose non-standard products because they allow them to examine the particular characteristics of each project, as well as verify the authenticity of the credit they purchase and thus safeguard themselves from allegations of greenwashing.

The exchanges are often used to settle huge bilateral agreements that were concluded offscreen. In a market note published during May CBL stated that they had an greater number of bilateral agreements negotiated offscreen were brought in by traders for settlement through CBL’s platform. CBL platform.

These deals comprised an important portion of the volume that were transacted on CBL.


Brokers purchase carbon credits directly from retailer trader, and then sell the credits to a buyer typically with a commission.


There is a fifth party that is unique to carbon markets. Standards are usually organizations, typically non-profit organizations, that verify that a specific project is in line with the stated goals and declared emissions levels.

Standards provide a set of methods, or guidelines for every type of carbon-related project. For instance Reforestation projects must be guided by specific guidelines when calculating the amount of CO2 absorption of the forest planned and consequently the amount of carbon credits it generates over the course of time.

Renewable energy projects has a set of rules that must be able to follow when calculating the benefits in terms of avoiding CO2 emissions as well as carbon credits that are generated over the course of.

Certifications issued by Standards also guarantee certain fundamental principles or standards of carbon finance are met:

Additionality: The project must not require a legal requirement, a common procedure, or financially appealing without credits revenues.
The CO2 emissions reductions should be in line with the amount of offset credits that are issued for the project, and it should also into account any unintentional GHG emissions resulting from the project.
Permanence: The effect of the GHG reduction in emissions should not be in danger of reversal and will result in a long-lasting reduction in emissions.
Unique claim: Every metric tonne of CO2 is only claimed one time and must be accompanied by evidence of the credit retirement at the time of project completion. Credits are offsets when it is retired.
Offer additional environmental and social benefits: Projects should comply with the legal requirements of the jurisdiction of the project and must provide additional benefits that are in line to the United Nations’ SDGs.

Trade, trade and overlapping roles

There is a resemblance of roles, which is unique for carbon market.

Many brokers are traders, and a lot of financiers have brokering arms as well as arm for project development.

End buyers may also fund their own carbon projects and choose to keep all or a portion of the credits issued for their own offset needs.

Each of these organizations could eventually sell credits to a buyer or developer, or decide to sell them directly. These juxtapositions could affect the prices, and eventually affect the transparency of markets.

Pricing from a variety of sources

If a business decides to use market for carbon credits that are voluntary as a possible method of compensating for its carbon emissions One of the most important elements it is looking for is the cost for carbon credit. Based on this data the company can determine the level of ambition it will need in setting its goal for reducing emissions and whether the market for voluntary carbon credits can actually help to achieve it.

In the same way the clear value signal on carbon permits those who are already on the marketplace to be sure that they’re trading their carbon at a value that is in line with the market value.

However, determining the price of carbon credits isn’t an easy task, mainly due to the variety of carbon credits available and the variety of factors that influence the price.

Carbon credits issued by projects are of a variety of kinds and sub-types. What is the nature of the underlying project is among the primary factors that affect the cost for the credits.

Carbon credits can be classified into two broad baskets or categories that include avoidance projects (which are designed to avoid the emission of GHGs completely, thus reducing the amount of GHGs released to the air) as well as removal (which eliminates GHGs completely from the air).

The basket of avoidance includes renewable energy sources, but also the forestry and farming emissions reduction projects. These, often referred to as REDD+, stop destruction of wetland habitats or deforestation, or employ soil management techniques in agriculture that reduce GHG emissions, such as projects that aim to reduce emission from milk cows as well as beef cattle by varying their diets.

Cookstove projects as well as fuel efficiency projects or the construction of energy efficient buildings are included in the avoidance basket as do projects for capturing and eliminating industrial pollutants.

The removal sector includes projects that capture carbon from the air and storing it. They could be based on nature that use trees or soil for example , to remove carbon and store it. Examples include afforestation and reforestation projects, as well as wetland management (forestry and agriculture). They may also be based on technology and incorporate technologies such as direct air capture, or carbon storage and capture.

Credits for removal are typically traded at a higher price than avoidance credits, and not only due to the greater amount of investment required by the base project, but also due to the huge demand for these types of credit. They also are considered to be a more effective instrument in fighting climate change.

Beyond the nature of the project that is the basis, the cost of carbon credits can also be affected by the amount of credits that are traded at a period (the greater the volume, the less expensive, generally) and the location that the company is located in, its age (typically the more old the year, the lower the cost) and also the time to deliver.

If the carbon project is also helping to achieve some of the UN’s SDGs and goals, the worth of a credit from the project to prospective buyers could be greater, and the credit could be traded at a higher price than other kinds of projects.

For instance, community-based initiatives that are typically localized and usually developed and run through local groups, NGOs or even a volunteer – tend to yield smaller amounts in carbon credits. They are also more costly to be able to verify them. But, they typically provide greater co-benefits in addition to meeting the UN’s SDGs which contribute for example, better living conditions for the population in the area, improved water quality, or decrease in economic inequality.

This is why credits generated by community-based initiatives could be traded at a premium to projects that do not meet SDGs, like industrial ones, as they tend to be larger in scale and often generate huge amounts of credits, with greater, more easily verified GHG offset possibilities.

In the current market for carbon credits the cost of a carbon credit can range between a couple of cents for each carbon dioxide emissions metric tons to as high as $15/mtCO2e, or even $20/mtCO for projects that afforest or reforest up to $300 or $100 for mtCO2e for removal projects that are based on technology like CCS.
