A carbon credit is a tradable permit representing one tonne of carbon dioxide equivalent (tCO2e) that has been reduced, avoided, or removed from the atmosphere. In India, carbon credits work in two ways: companies in energy-intensive sectors earn Carbon Credit Certificates under the compliance mechanism by beating their emission targets, while businesses, farmers, and project developers can generate voluntary credits from activities like renewable energy, afforestation, or waste management. These credits can then be sold to companies that want to offset their own emissions or meet regulatory obligations.

Carbon markets work by putting a price on emission reductions so they can be bought and sold. In a compliance market, the government sets emission or intensity targets for industries, and companies that outperform their targets earn certificates they can trade to companies for whom cutting emissions is more expensive. In the voluntary market, project developers generate credits from activities such as reforestation, clean energy, or methane capture and sell them to corporations pursuing net-zero commitments. Trading happens on registered exchanges, registries, or through brokers, with prices reflecting the quality and cost of the underlying reductions.

The carbon credits trading scheme — formally the Carbon Credit Trading Scheme (CCTS) — is India's compliance carbon market framework, introduced under the Energy Conservation (Amendment) Act, 2022, with the Bureau of Energy Efficiency as administrator. It sets greenhouse gas emission targets for designated industries in sectors like steel, cement, aluminium, fertilisers, and petrochemicals; entities that outperform their targets earn tradable carbon credit certificates, while those that fall short must buy them. The CCTS forms the compliance backbone of the carbon market in India, and a parallel offset mechanism lets non-obligated entities voluntarily register projects and earn credits.

In India, carbon markets are monitored under the Energy Conservation (Amendment) Act, 2022, which amended the Energy Conservation Act, 2001 to give the government legal authority to establish a domestic carbon credit trading scheme. Under this framework, the Bureau of Energy Efficiency under the Ministry of Power administers the scheme, a National Steering Committee for the Indian Carbon Markets provides governance oversight, and SEBI regulates the trading side. Knowing this structure is important for both compliance entities and developers planning to register carbon projects.

To sell carbon credits in India, you first need a project or activity that verifiably reduces or removes emissions — such as renewable energy, energy efficiency, afforestation, waste management, or clean cooking. Next, register the project under an eligible mechanism: the CCTS offset mechanism for the domestic market, or international standards like Verra or the Gold Standard for voluntary buyers. After validation, monitoring, and third-party verification, credits are issued to your account and can be sold through registered exchanges, registries, aggregators, or direct corporate buyers. Small project owners and farmers usually get better outcomes by pooling land or activity through an aggregator rather than selling individually.

The carbon credits price in India is not fixed — it depends on whether the credit is compliance-grade or voluntary, along with the project type, standard, vintage year, and buyer demand. Compliance carbon credit certificates under the CCTS trade at a market-discovered price on exchanges, while voluntary credits from Indian projects have generally ranged from a few dollars per tonne for common avoidance projects to significantly more for high-quality removals with strong community or biodiversity co-benefits. Since prices move frequently, check current rates on registered exchanges or with aggregators before finalising a sale.

Carbon credits registration in India follows a defined sequence: confirm your project is eligible under the chosen mechanism, prepare a project design document detailing the methodology and expected emission reductions, get it validated by an accredited third party, and register it with the relevant body — the Bureau of Energy Efficiency for the domestic CCTS offset mechanism, or international registries like Verra and Gold Standard. After registration, you monitor actual reductions, have them verified, and only then are credits issued. The full cycle typically takes several months to over a year, so planning documentation and timelines early is essential.

Carbon credits for farmers in India come from practices that remove carbon or cut farm emissions — agroforestry and tree planting, reduced tillage, alternate wetting and drying in paddy to reduce methane, applying organic compost, and improving soil health. Because individual plots are small and measurement is costly, farmers typically earn through aggregated projects where an aggregator registers the land under a carbon standard, handles measurement and verification, and shares revenue with participating farmers. Be cautious of agents promising guaranteed payouts or demanding upfront registration fees — genuine carbon projects pay after verified credits are actually sold.

Article 6 of the Paris Agreement sets the rules for international cooperation on emission reductions, including through carbon markets. Article 6.2 allows countries to trade emission reductions bilaterally toward their climate targets, Article 6.4 creates a centralised crediting mechanism (the successor to the Clean Development Mechanism), and Article 6.8 covers non-market approaches. For Indian project developers and carbon credit exporters, Article 6 matters because internationally traded credits may require corresponding adjustments and must meet stricter authorisation and quality standards.

Carbon markets UPSC questions usually revolve around a core set of facts: what carbon credits are, the Energy Conservation (Amendment) Act, 2022 as the legal basis, the Carbon Credit Trading Scheme and the role of the Bureau of Energy Efficiency, the difference between compliance and voluntary markets, and Article 6 of the Paris Agreement for international linkages. Prelims questions tend to test the institutional setup, while mains answers score better when you connect carbon markets to India's net-zero-by-2070 commitment, climate finance, and industrial decarbonisation.

ESG reporting in India is the structured disclosure of a company's environmental, social, and governance performance — covering areas like energy use, emissions, water, waste, employee welfare, diversity, and board practices. For the top 1,000 listed companies by market capitalisation, SEBI mandates this through the Business Responsibility and Sustainability Report (BRSR), with assurance requirements being phased in for BRSR Core disclosures. Even unlisted companies increasingly prepare ESG reports because exporters, lenders, and global customers now demand sustainability data from their Indian suppliers and partners.

ESG reporting frameworks used in India fall into two buckets. The mandatory one is SEBI's BRSR for the top 1,000 listed companies. Voluntarily, Indian companies commonly adopt global ESG reporting standards — GRI for impact-focused disclosure, ISSB's IFRS S1 and S2 (which absorbed SASB and TCFD) for investor-focused disclosure, and CDP questionnaires for climate, water, and forests. Companies supplying to European customers also track the EU's CSRD, since it affects Indian suppliers. Most organisations start with BRSR if listed, then map the same data to GRI or ISSB for international stakeholders.

To make an ESG report, start by defining the reporting boundary (which entities and operations are covered), then run a materiality assessment to identify the ESG issues most relevant to your business and stakeholders. Next, collect data across environmental metrics (energy, Scope 1 and 2 emissions, water, waste), social metrics (safety, workforce diversity, community initiatives), and governance metrics (board composition, policies, ethics), and structure the disclosure using a recognised framework such as BRSR, GRI, or ISSB. Finish with internal review, third-party assurance if required, and publication. First-time reporters most often underestimate data collection, so setting up an ESG data system early saves months of rework.

The most effective way to learn ESG reporting is to combine structured study with hands-on practice. Begin with an ESG reporting certification or short course — options include GRI-certified training, ISSB and SASB fundamentals, and sustainability programmes from IIMs, IITs, and global professional bodies — to build framework knowledge. Then practise by studying published BRSR and GRI reports of Indian companies, recreating their disclosures from raw data, and working on a live project or internship. With BRSR Core assurance becoming mandatory, professionals with accounting, audit, or engineering backgrounds who add ESG reporting skills are seeing strong demand.

ESG reporting in accounting refers to measuring, recording, and assuring environmental, social, and governance data with the same rigour as financial information. It covers how climate-related risks and opportunities affect financial statements, how emissions and sustainability metrics are compiled and audited, and how frameworks like the ISSB standards connect sustainability disclosures to financial reporting. For chartered accountants and auditors in India, this is a fast-growing area, because SEBI is phasing in mandatory assurance of BRSR Core — creating demand for professionals who can audit non-financial data reliably.
