Also known as carbon allowances, carbon credits signify the elimination, minimization, and avoidance of one metric ton of carbon dioxide equivalent (CO₂e) emissions per credit. Being a market-based tool and universal unit of measurement, carbon credits can be easily bought as well as sold to financially back climate reduction projects or compensate for the emissions generated by an organization.
In simple words, carbon credits work as a permit, allowing a business to release CO₂e. For instance, if a company buys a carbon emission credit, they get permission to produce only one metric ton of carbon emissions. Purchasing a carbon credit enables a company to counterbalance the GHG emissions that they are accountable for. It is noteworthy that these credits can be traded between countries, governments, and companies.
Carbon credits were initially introduced under the United Nations’ Kyoto Protocol through mechanisms like the Clean Development Mechanism (CDM), allowing countries and companies to earn credits by supporting verified emission-reduction projects. Today, carbon credits are available through both compliance and voluntary markets. Generally, the companies are allowed to emit a set number of GHG emissions, but once they exceed the given limit, they need to purchase the carbon credits to offset the excess emissions. Every owner of the carbon credit holds accountability for the issuance, monitoring, and reporting of their carbon credit status every single year. In case a company ends up buying plenty of carbon credits, it can further sell the extra credits at a carbon marketplace or carbon exchange. This exchange is popularly known as a cap-and-trade program in compliance markets.

Despite their potential, carbon credits come with notable drawbacks that businesses must consider. One major concern is the risk of double counting and limited transparency, which can compromise the credibility of emissions reporting. Additionally, some credits may support projects that don’t deliver real or lasting emission reductions, especially if not properly verified or maintained. There’s also the issue of a “pay to pollute” mindset, where companies rely on offsets instead of reducing their actual emissions, thereby raising concerns around greenwashing. Lastly, the complexity and inconsistency of standards across voluntary and compliance markets make it difficult to assess the quality and impact of credits. These factors underscore the importance of careful selection and integration of carbon credits within a credible, science-aligned sustainability strategy.
The future scope of carbon credits seems fruitful for several reasons. The trading systems are becoming more liquid and mature, therefore experiencing a flourishing culture. Governments around the world are stepping up their environmental action, reflecting a strong worldwide environmental pledge.
At the same time, the demand for environment-focused goods is on the rise, indicating growing investor interest. There is also significant potential for widespread expansion of cap-and-trade systems into new sectors, creating new market possibilities.
Additionally, increased collaboration between carbon markets is on the horizon, further strengthening the global carbon credit landscape.

Carbon credits, also called carbon allowances, represent the reduction, removal, or avoidance of one metric ton of carbon dioxide equivalent (CO₂e) emissions. They act as tradable permits that allow businesses, governments, or individuals to compensate for their greenhouse gas emissions by financially supporting verified climate mitigation projects.
Carbon credits operate as a market-based mechanism where companies are allocated or purchase a set amount of permissible emissions. If they exceed their limit, they buy credits from entities that have reduced emissions elsewhere. These credits are traded in compliance or voluntary markets, and ownership requires proper issuance, monitoring, and annual reporting.
Carbon credits are issued by regulatory bodies in compliance markets, such as governments running emissions trading schemes, or by independent organizations and standards in voluntary markets, such as Verra (VCS), Gold Standard, and Climate Action Reserve, which certify and verify emission-reduction projects.
To buy carbon credits, businesses select a suitable carbon market, choose a reliable exchange or broker, open an account, assess their carbon footprint to determine the required amount, and place an order to purchase the credits, which are then added to their account for offsetting emissions.
To sell carbon credits, businesses or project owners select a carbon market, open an account with a trusted exchange or broker, provide details of their credits, set a price based on quality and market conditions, and transfer ownership to a buyer once payment is received.
