Carbon Trading and Carbon Markets: Global and Indian Context

July 19, 2026

TOPIC CLASSIFICATION

Subject: Environment & Ecology — Climate Change Mitigation
Sub-topic: Carbon Trading — Emissions Trading Schemes (ETS), Carbon Credits, Clean Development Mechanism (CDM), Article 6 of Paris Agreement, India's Carbon Market
Mains GS Paper-III: Environment — climate change policies, international environmental conventions, market-based mechanisms.


EXAMINER REASONING

Carbon trading is a market-based mechanism that puts a price on carbon — a favourite topic for UPSC because it tests understanding of both economics and environment. Prelims tests: Kyoto Protocol mechanisms (CDM, JI, IET), terminology (carbon credit, carbon offset, carbon tax, ETS), India's current status. Mains demands: (a) the architecture of carbon markets — compliance vs. voluntary markets, (b) India's proposed Carbon Credit Trading Scheme (CCTS) , (c) Article 6 of Paris Agreement — how cooperative approaches work, (d) the debate on carbon border adjustment mechanisms (CBAM), (e) comparison of carbon tax vs. cap-and-trade. The examiner's framing is: "Can carbon markets truly deliver emission reductions or are they a distraction?"


Core Concept

What are Carbon Markets?

Carbon markets are trading systems where carbon credits (permits to emit a certain amount of CO₂) are bought and sold. The goal is to reduce emissions by putting a price on carbon — making pollution costly and clean alternatives competitive.

Types of Carbon Markets:

TypeDescriptionExample
Compliance MarketCreated by mandatory national/regional cap-and-trade systemsEU ETS, California Cap-and-Trade, China National ETS
Voluntary MarketCompanies/organisations buy carbon credits voluntarily to offset emissionsVerra (VCS), Gold Standard (GS), CORSIA (aviation)

Air Pollution: Causes, Effects, and Policy Response

Air pollution is India's deadliest environmental problem — responsible for over 1.6 million deaths annually. This note covers sources (vehicles, industry, biomass burning), health and economic impacts, the National Clean Air Programme (NCAP), and the Commission for Air Quality Management (CAQM).

Kyoto Protocol Mechanisms (Flexible Mechanisms):

MechanismDescriptionWho Benefits
Clean Development Mechanism (CDM)Annex I countries invest in emission-reduction projects in Non-Annex I countries → earn CERsDeveloped countries meet targets cost-effectively; developing countries get clean tech
Joint Implementation (JI)Annex I countries invest in emission-reduction projects in other Annex I countries → earn ERUsTransition economies (e.g., Russia, Ukraine)
International Emissions Trading (IET)Annex I countries trade Assigned Amount Units (AAUs) among themselvesAll Annex I parties

Article 6 of Paris Agreement (Post-2020):

ProvisionPurpose
Article 6.2Bilateral/multilateral cooperative approaches — countries can trade Internationally Transferred Mitigation Outcomes (ITMOs)
Article 6.4New mechanism to replace CDM — Sustainable Development Mechanism (SDM)
Article 6.8Non-market approaches — cooperation without carbon trading (e.g., technology transfer, capacity building)
Corresponding AdjustmentsWhen credits are traded internationally, the selling country must adjust its NDC accounting to avoid double counting

India's Carbon Market:

DevelopmentYearStatus
Perform, Achieve, Trade (PAT) Scheme2012Energy efficiency certificates (ESCerts) — operational
Renewable Energy Certificates (RECs)2010Trading in renewable energy obligations
Energy Saving Certificates2017Under PAT Scheme
Carbon Credit Trading Scheme (CCTS)2023-24Launched for compliance sector; voluntary market guidelines being drafted
Carbon Tax (Implicit)2010+Clean Energy Cess → GST Compensation Cess on coal; implicit carbon price of ~$3-5/tonne

Key Facts

FactDetail
Largest carbon marketEU ETS (~€90 billion value in 2023)
First carbon marketEU ETS (launched 2005)
China's national ETS launchedJuly 2021 — covers ~4.5 billion tonnes CO₂ (largest by volume)
India's implied carbon price$3-5/tonne (through coal cess) — very low vs. EU ETS (€80-100)
Current CDM credits held by IndiaIndia is 2nd largest seller of CDM credits (after China)
Voluntary carbon market value~$2 billion (2023) — projected to grow

Statement Elimination Guide

StatementTruth ValueWhy?
"CDM projects are only allowed in developing countries"TrueCDM allows Annex I countries to fund emission reduction projects in Non-Annex I parties
"Article 6 of the Paris Agreement replaced the Kyoto Protocol"FalseArticle 6 provides the new framework for carbon markets under the Paris Agreement; Kyoto Protocol mechanisms were not directly replaced
"India has a mandatory carbon market"Partly TrueIndia has sectoral compliance markets (PAT, REC) but no economy-wide mandatory carbon market yet
"Carbon tax and carbon trading are the same thing"FalseCarbon tax is a fixed price on emissions; carbon trading uses market-based cap-and-trade — the price is set by market forces
"Corresponding adjustments prevent double counting of emission reductions"TrueWhen ITMOs are traded internationally, the selling country must make a corresponding adjustment to its NDC

Current Affairs Hook

2023-26: India's Carbon Credit Trading Scheme (CCTS) was notified in 2023 under the Bureau of Energy Efficiency (BEE) — this is India's first compliance carbon market for the industrial sector (hard-to-abate sectors like steel, cement, aluminium). The EU's Carbon Border Adjustment Mechanism (CBAM) , starting 2026, will impose a carbon price on imports from countries without equivalent carbon pricing — this directly affects Indian exports (steel, aluminium, cement). India has raised concerns at WTO about CBAM being discriminatory and protectionist. The voluntary carbon market is growing — Indian companies are buying carbon credits for ESG commitments. The COP29 (2024) focus on Article 6.4 rules is crucial for operationalising the new carbon market mechanism. India is also exploring a domestic carbon market for the agriculture sector.


Interlinkages

  • → Climate Change (GS-III): Carbon markets are a tool to meet NDCs and the Paris Agreement goals
  • → International Relations (GS-II): EU CBAM — India's trade and climate diplomacy at WTO, COP
  • → Environment Conventions (GS-III): Kyoto Protocol → Paris Agreement → Article 6 evolution
  • → Energy Sector (GS-III): PAT Scheme, RECs, coal cess — India's energy transition policies
  • → Economy (GS-III): Carbon pricing, green finance, the cost of transition

Common Mistakes

MistakeCorrection
"Carbon credits and carbon offsets are the same"Carbon credits are tradable permits under a cap; carbon offsets represent emission reductions from projects — often used interchangeably but different conceptually
"India has no carbon pricing mechanism"India has an implicit carbon price through coal cess (~$3-5/tonne) — and the CCTS is being operationalised
"CDM projects are still operational under the Paris Agreement"CDM ended under the Kyoto Protocol; the Paris Agreement established Article 6.4 mechanism to replace CDM
"Carbon trading is only done internationally"Domestic carbon markets (EU ETS, China ETS, India's CCTS) are larger than international trading
