What are carbon markets and how do they operate?

Context

Recently passed Energy Conservation (Amendment) Bill, 2022 empowers the Government to establish carbon markets in India and specify a carbon credit trading scheme.

What are carbon markets?

  • To meet Nationally determined contributions (NDCs), one mitigation strategy is becoming popular with several countries— carbon markets.
  • Article 6 of the Paris Agreement provides for the use of international carbon markets by countries to fulfil their NDCs.
  • Carbon markets are essentially a tool for putting a price on carbon emissions— they establish trading systems where carbon credits or allowances can be bought and sold.
  • A carbon credit is a kind of tradable permit that, per United Nations standards, equals one tonne of carbon dioxide removed, reduced, or sequestered from the atmosphere.
  • These markets create incentives to reduce emissions or improve energy efficiency.


Sentiments of countries about carbon markets

  • About 83% of NDCs submitted by countries mention their intent to make use of international market mechanisms to reduce greenhouse gas emissions.

What are the types of carbon markets?

  • There are broadly two types of carbon markets that exist today— compliance markets and voluntary markets.

Voluntary Markets

Compliance Markets

  • Here, the Emitters— corporations, private individuals, and others— buy carbon credits to offset the emission.
  • Compliance markets are set up by policies at the national, regional, and/or international levels— that is officially regulated.
  • In voluntary markets, credits are verified by private firms as per popular standards.
  • Most of these markets operate under a principle called ‘cap-and-trade”.
  • Here the participants purchase emissions reductions for public relations or personal reasons.
  • Here the carbon offsets are created by the need to comply with a regulatory act
  • There are traders and online registries where climate projects are listed and certified credits can be bought.

Examples of compliance carbon markets are the:

  • Kyoto Protocol
  • European Union emissions trading system
  • California emissions trading system (ETS)
  • Australia ETS
  • British Columbia ETS
  • New Zealand ETS
  • China launched the world’s largest ETS in 2021.

 

Cap-and-Trade vs Carbon Tax

  • A carbon tax and cap-and-trade are opposite sides of the same coin.
  • A carbon tax sets the price of CO2 emissions and allows the market to determine the amount of reduced emissions.
  • A cap-and-trade system sets the quantity of emissions allowed, which can then be used to estimate the decline in the rise of global temperatures.
    • The market price of carbon gets determined by market forces when purchasers and sellers trade in emissions allowance.

  • PLI Scheme: Diversification of the supply chain by introducing a production-linked incentive scheme for the manufacturing of polysilicon cells into modules.
  • Clean Development Mechanism: In India, the clean development mechanism under the Kyoto Protocol provided a primary carbon market for the players.
  • Energy Conservation (Amendment) Bill, 2022
  • These markets may promote the reduction of energy use and encourage the shift to cleaner fuels.
  • Through this kind of carbon trading, companies can decide if it is more cost-efficient to employ clean energy technologies or to purchase additional allowances.
  • Since government-regulated trading schemes may prompt companies to innovate, invest in, and adopt cost-efficient low-carbon technologies.

What are the challenges to carbon markets?

  • Effectiveness of carbon markets: Some companies simply buy credits without making any effort to reduce emissions themselves.
    • It is cheaper for them to buy carbon credit than to invest in emission-reducing technologies.
  • Environmental activists argue that only high-quality carbon offsets are effective in reducing emissions. High-quality carbon offsets have certain features:
    • Additionality: Emission reductions must be additional i.e., they would not have occurred in the absence of a market for offset credits e.g., a renewable project could be set up only because a high emitter paid for it.
    • Verifiable: There must be proper audits to ensure the monitoring, reporting, and verification of emission cuts.
    • Permanence: The emission reduction should not be reversed.
  • However, many credits available in markets are of poor quality i.e., they do not meet the above criteria.
  • Buying carbon credits can deviate rich nations from the path of reducing emissions.
  • It is difficult to establish the amount of carbon reduced by offset projects (like afforestation or wind energy project).
