Carbon Credit Trading Scheme

A Carbon Credit Trading Scheme (CCTS) is a regulatory instrument that places a price on greenhouse-gas emissions by creating tradable units—each credit notionally equal to one tonne of carbon dioxide equivalent (tCO₂e)—that can be bought, sold, banked, or surrendered against compliance obligations. The architecture draws directly from Article 17 of the Kyoto Protocol (1997), which introduced international emissions trading, and the project-based Clean Development Mechanism under Article 12. This was superseded by Article 6 of the Paris Agreement (2015), where Article 6.2 governs cooperative bilateral transfers (Internationally Transferred Mitigation Outcomes, ITMOs) and Article 6.4 establishes a centralised UN crediting mechanism, the operational rules for which were finalised at COP29 in Baku (2024). India's domestic scheme rests on the Energy Conservation (Amendment) Act, 2022, which empowered the central government to notify a carbon market, operationalised through the Carbon Credit Trading Scheme, 2023 notified by the Ministry of Power.

Schemes operate on two broad models. A cap-and-trade (compliance) market sets an absolute or intensity-based emissions ceiling, allocates allowances to covered entities, and lets surplus holders sell to those exceeding their cap—the design of the EU Emissions Trading System (EU ETS, 2005), the world's largest. A baseline-and-credit model issues credits only for verified reductions below a benchmark, the logic of voluntary carbon markets certified by bodies such as Verra (VCS) and Gold Standard. India's CCTS is hybrid: a compliance mechanism sets greenhouse-gas-intensity targets for obligated industries, while a parallel offset mechanism allows non-obligated entities to earn and sell credits for registered mitigation projects. The scheme is administered by the Bureau of Energy Efficiency (BEE) as administrator, the Grid Controller of India as registry, and the Central Electricity Regulatory Commission (CERC) as market regulator, building on the earlier Perform, Achieve and Trade (PAT) scheme's ESCerts framework.

As of 2026, the EU ETS is in its Phase 4 (2021–2030) with a strengthened Market Stability Reserve and an expanding Carbon Border Adjustment Mechanism (CBAM) that, from January 2026, levies charges on the embedded carbon of imports such as steel, cement, aluminium, and fertilisers—directly affecting Indian exporters. India's CCTS is moving toward issuing its first Carbon Credit Certificates (CCCs), with sectoral GHG-intensity trajectories notified for energy-intensive industries; China operates the largest national ETS by covered emissions, launched in 2021 for the power sector. The integrity of any scheme turns on additionality (would the reduction have happened anyway), robust measurement, reporting and verification (MRV), and avoidance of double counting, addressed through Article 6's "corresponding adjustments."

For the UPSC examination, this term is core to GS Paper III (environment, conservation, economic development) and frequently appears in Prelims through the distinction between cap-and-trade and offsets, the PAT-ESCerts linkage, and Kyoto versus Paris mechanisms. Mains questions probe whether market-based instruments are superior to carbon taxes, the equity implications of CBAM for developing economies, and India's balancing of growth with its Nationally Determined Contributions and 2070 net-zero pledge. Candidates should be able to name the EC(A) Act 2022, CCTS 2023, BEE's role, and Article 6 sub-clauses precisely.
