Introduction to carbon credits and CCTS
Climate change is one of the biggest environmental challenges facing the world today. Greenhouse gases such as carbon dioxide (CO₂), methane (CH₄) and nitrous oxide (N₂O) trap heat in the atmosphere, causing global warming. Industries, transportation, electricity generation and other human activities release these gases into the atmosphere. To reduce these emissions, many countries have introduced policies that encourage cleaner production. One such policy is the Carbon Credit Trading Scheme (CCTS).
Carbon credits are an economic tool that motivates companies to reduce greenhouse gas emissions. Instead of only imposing penalties on polluting industries, carbon credits reward companies that successfully reduce their emissions. This creates a financial incentive for businesses to adopt cleaner technologies and improve energy efficiency.
What are Carbon Credits?
A carbon credit is a certificate that represents the reduction or removal of one metric tonne of carbon dioxide or its equivalent greenhouse gases (tCO₂e). In simple terms, a carbon credit works like a reward point:
- If a company reduces its carbon emissions below the target set by the government, it earns carbon credits.
- If a company emits more than its allowed limit, it must buy carbon credits from another company that has reduced more emissions than required.
This system encourages industries to reduce pollution, because reducing emissions can generate additional income through the sale of carbon credits.
Why are Carbon Credits Important?
Carbon credits provide both environmental and economic benefits. From an environmental perspective, they encourage industries to reduce greenhouse gas emissions, helping to slow climate change and improve air quality. From an economic perspective, companies that invest in cleaner technologies can earn carbon credits and generate additional revenue by selling them to other companies. Carbon credits therefore help balance environmental protection with economic growth.
The Carbon Market
A carbon market is a marketplace where carbon credits are bought and sold. Companies that reduce emissions can sell their excess carbon credits, while companies that are unable to meet their emission targets can purchase these credits to comply with government regulations. The carbon market creates a financial value for reducing emissions, making environmental protection part of normal business operations.
India's Carbon Credit Trading Scheme (CCTS)
India introduced the Carbon Credit Trading Scheme under the Energy Conservation (Amendment) Act, 2022. The scheme was officially notified in June 2023, and detailed operational procedures were released in July 2024.
The main objective of the CCTS is to reduce greenhouse gas emissions from industries while supporting India's climate commitments. The scheme is managed by the Bureau of Energy Efficiency (BEE) under the guidance of the Ministry of Power and the Ministry of Environment, Forest and Climate Change.
How the CCTS Works
- The government sets an emissions intensity target for each covered industry.
- During the financial year, companies monitor and record their greenhouse gas emissions.
- At the end of the year, each company compares its actual emissions with its assigned target.
- If the company emits less than the target, it receives Carbon Credit Certificates (CCCs).
- If the company emits more than the target, it must purchase Carbon Credit Certificates from companies that have excess credits.
This process rewards efficient industries while encouraging others to improve their environmental performance.
A Simple Example
Suppose a cement company is allowed to emit 100 tonnes of CO₂ in a year. If it emits only 90 tonnes, it has reduced emissions by 10 tonnes and receives 10 Carbon Credit Certificates.
Another company emits 110 tonnes instead of its allowed 100 tonnes. It must buy 10 Carbon Credit Certificates from the first company to meet its compliance requirement. As a result, the company that reduced pollution earns money, while the company that exceeded its target bears the additional cost.
Industries Covered
Initially, the Indian Carbon Credit Trading Scheme covers seven major energy-intensive industries, selected because they contribute significantly to greenhouse gas emissions:
- Aluminium
- Cement
- Chlor-alkali
- Petrochemicals
- Petroleum refining
- Pulp and paper
- Textiles
Greenhouse Gases Covered
The scheme currently includes carbon dioxide (CO₂) and perfluorocarbons (PFCs). It mainly covers Scope 1 (direct) emissions and Scope 2 (indirect emissions from purchased electricity), along with certain Scope 3 emissions related to intermediate product imports and exports.
Benefits of the CCTS
- Encourages industries to reduce greenhouse gas emissions.
- Promotes energy efficiency and cleaner technologies.
- Creates financial rewards for environmentally responsible companies.
- Supports India's Nationally Determined Contributions (NDCs).
- Contributes to India's Net Zero target by 2070.
- Builds a transparent national carbon market.
Challenges
- Some industries may need to invest heavily in cleaner technologies.
- Accurate monitoring, reporting and verification of emissions require technical expertise.
- Carbon credit prices may fluctuate depending on market demand.
- Small industries may face financial and technical difficulties in adapting to the new system.
Future Outlook
The Carbon Credit Trading Scheme is expected to expand to more industries over time. As India strengthens its climate policies, the carbon market will play an increasingly important role in reducing emissions while supporting sustainable economic growth. With proper implementation, the CCTS can help industries become more energy-efficient, competitive and environmentally responsible.
Conclusion
Carbon credits are an innovative approach to reducing greenhouse gas emissions by combining environmental responsibility with financial incentives. The Indian Carbon Credit Trading Scheme encourages industries to emit less carbon by rewarding better environmental performance and requiring companies that exceed their emission targets to purchase carbon credits.
Rather than relying only on penalties, the scheme motivates industries to adopt cleaner technologies and improve efficiency. As India moves toward its goal of Net Zero emissions by 2070, the Carbon Credit Trading Scheme will become an important tool in supporting sustainable industrial development, environmental protection and long-term economic growth.
