Carbon Trading

 

Human activities, particularly the burning of fossil fuels such as coal, oil, and natural gas, along with various industrial processes, release significant amounts of greenhouse gases into the atmosphere. These gases, including carbon dioxide (CO₂), methane (CH₄), and nitrous oxide (N₂O), trap heat from the sun through a natural process known as the greenhouse effect. While the greenhouse effect is essential for maintaining temperatures that support life on Earth, the rapid increase in greenhouse gas concentrations due to human activities has intensified this effect, leading to global warming.

The continuous accumulation of greenhouse gases poses a profound threat to environmental stability, human health, and economic security. It exacerbates natural disasters, threatens food and water resources, and intensifies social and geopolitical tensions as communities struggle to adapt. Recognizing these risks, the global community has prioritized efforts to reduce emissions, transition to renewable energy sources, and implement policies aimed at mitigating climate change impacts.

Carbon Trading

Carbon trading is the trading of credits that permit a company or other entity to emit a certain amount of carbon dioxide or other greenhouse gases into the atmosphere. It is a market-based approach to controlling pollution by providing economic incentives for reducing the emissions of greenhouse gases. It is one of the strategies designed to combat climate change by putting a price on carbon emissions, encouraging companies or other entities to lower their carbon footprint. Buying credits enables the entity to pollute more than its nation's government allows. And those that emit less will have leftover permits to sell. In a carbon trading system, a governing body (like a government or international organization) sets a cap on the total amount of greenhouse gases that can be emitted by certain sectors or the entire economy. Emission allowances (also called carbon credits) are then distributed or auctioned to companies. Each allowance typically permits the holder to emit one metric ton of carbon dioxide or its equivalent in other greenhouse gases.

Purpose and Benefits

·         Carbon trading internalizes the external costs of emissions by assigning a price to carbon pollution, encouraging emitters to reduce emissions cost-effectively.

·         It creates financial incentives for investment in renewable energy and energy efficiency.

·         It supports countries and companies in meeting their climate targets under international agreements like the Paris Agreement.

·         International carbon markets under Article 6 of the Paris Agreement facilitate cooperation and trading of emission reductions between countries, enhancing ambition and sustainable development

Mechanism of Carbon Trading

Carbon markets are systems designed to incentivize the reduction of greenhouse gas emissions by assigning a price to carbon. They operate through the trading of carbon credits, which represent the right to emit a specific amount of greenhouse gases. The whole mechanism of carbon trading is explained below:

Setting a cap: A central authority (such as a government or an international body) sets an overall limit, or cap, on the total amount of greenhouse gases that can be emitted by all participating entities (such as industries, power plants, or even entire countries) over a certain period. The cap is typically reduced over time to progressively lower total emissions.

Allocation of allowances: Emission allowances (or permits) are then either allocated for free or auctioned to the participating entities. Each allowance typically gives the right to emit one metric ton of carbon dioxide (CO₂) or its equivalent in other greenhouse gases (CO₂e).

Monitoring and reporting emissions: Companies are required to measure and report their actual greenhouse gas emissions accurately and regularly, according to strict monitoring and verification standards. Independent third-party audits are often required to ensure credibility.

Trading: Companies that emit less than their allowed limit can sell their unused allowances to others who exceed their limits. This creates a market price for carbon, where supply and demand determine the cost of emitting greenhouse gases.

Compliance and penalties: At the end of each compliance period (typically one year), companies must surrender enough allowances to cover their actual emissions. If a company cannot cover its emissions with its allowances, it faces heavy fines or penalties.

Types of Carbon Markets

There are two main types of carbon markets: compliance and voluntary.

Compliance markets:  Compliance carbon markets are legally mandated systems established by governments or regulatory bodies with the primary goal of achieving predetermined emission reduction targets. These markets commonly operate through cap-and-trade systems. In such systems, a limit (cap) is set on the total allowable emissions within a specific jurisdiction or sector. Allowances, which are permits to emit a certain amount of greenhouse gases, are then distributed or auctioned to regulated entities. This creates a market dynamic where entities that manage to reduce their emissions below their allocated cap can sell their excess allowances (often referred to as carbon credits) to those entities that exceed their emission limits. This trading mechanism generates a financial incentive for companies to reduce their emissions and invest in cleaner technologies, as doing so can help them avoid the cost of purchasing additional allowances. Furthermore, the structured nature of these markets, often featuring tightening emission limits over time, encourages long-term investment in low-carbon innovation to ensure continued compliance and potential for profit through the sale of surplus credits.

Voluntary carbon markets:  Voluntary carbon markets provide a platform for organizations, institutions, and individuals to voluntarily offset their greenhouse gas emissions. In these markets, participants achieve this by purchasing carbon credits that are generated by projects specifically designed to reduce or remove emissions from the atmosphere. To maintain credibility and ensure environmental integrity, the carbon credits traded in these markets typically undergo rigorous verification by independent third-party organizations, such as Verra and the Gold Standard Foundation. These organizations establish comprehensive standards that emission reduction or removal projects must meet to be certified and subsequently issue carbon credits. This process offers a mechanism for entities to take responsibility for their unavoidable emissions and actively support a diverse range of climate action projects that go beyond their own operational boundaries.

India adopted regulations in 2024 for its planned compliance carbon market under the Carbon Credit Trading Scheme (CCTS), marking a significant step toward structured carbon trading in the country

In summary, carbon trading is a key tool in global climate policy, enabling cost-effective emission reductions through market mechanisms that incentivize cleaner energy and innovation while supporting international climate commitments.
