COP29, the ongoing climate conference in Azerbaijan’s capital Baku, has given a fillip to the idea of using carbon markets to curb carbon emissions by approving standards that can help in the setting up of an international carbon market as soon as the coming year.

Introduction to Carbon Markets

• Carbon markets allow the buying and selling of the right to emit carbon dioxide (CO2) into the atmosphere.
• Governments issue certificates known as carbon credits, each representing the right to emit 1,000 kilograms of CO2.
• The total number of credits issued is capped to control carbon emissions. Companies and individuals who don’t have credits cannot emit CO2.

Trading of Carbon Credits

• Carbon Credit Trading: Companies holding more carbon credits than needed can sell them to others who need more, with the price determined by market forces.
• Carbon Offsets: Businesses can also purchase carbon offsets, often provided by environmental NGOs, which promise to reduce emissions (e.g., by planting trees). These offsets counterbalance the firm’s carbon emissions.
• The trading of both credits and offsets is designed to create financial incentives for companies to reduce their carbon footprint.

Advantages of Carbon Markets

• Addressing Externalities: Carbon emissions are a classic example of an economic externality, where the costs of pollution are not reflected in market prices.
• Market Efficiency: By allowing firms to buy and sell carbon credits, the system internalizes the cost of carbon emissions, encouraging businesses to reduce emissions to avoid higher costs.
• Incentive for Emission Reduction: Carbon markets aim to create a financial reason for companies to lower their emissions, thus helping mitigate climate change.

Voluntary vs. Government-Mandated Carbon Markets

• Voluntary Carbon Reporting: Many corporations prefer voluntary systems like the Carbon Disclosure Project (CDP) for reporting their emissions, fearing government-imposed restrictions.
• Market Flexibility: Corporations like ExxonMobil and General Motors argue that carbon markets with freely traded credits allocate carbon allowances more efficiently than government-imposed limits. This allows firms to purchase credits from others, optimizing resource allocation without restricting output.
• Corporate Resistance to Government Intervention: Firms are often reluctant to accept strict government budgets for carbon emissions, fearing increased operational costs and production limitations due to diverse supply chains.

Issues and Criticisms of Carbon Markets

• Government Manipulation of Credit Supply: Governments may increase the number of carbon credits issued, leading to lower prices and reduced incentives for emission reductions.
• Lack of Accountability in Carbon Offsets: Critics argue that some companies buy carbon offsets as a form of virtue signalling, without genuine concern for their environmental impact. This undermines the effectiveness of the offsets.
• Government Mismanagement: Political decision-making may lead to the over-restriction of carbon credits, potentially slowing economic growth by limiting available emissions allowances. The ability of governments to accurately determine the optimal supply of carbon credits is a contentious issue.

The Concept of Carbon Credits and Their History

• Introduction of Carbon Credits: Carbon credits were first introduced in the 1990s in the U.S., specifically through a cap-and-trade model designed to control sulfur dioxide emissions. This approach later expanded to include carbon emissions.
• Role of Carbon Markets: In essence, these markets aim to create a financial mechanism where firms can trade the right to pollute, ensuring a balance between economic growth and environmental protection.

Criticism of Carbon Offsets

• Effectiveness of Offsets: Experts are critical of carbon offsets, arguing that they do not always lead to meaningful reductions in emissions. For example, some companies may purchase offsets without ensuring that the projects are genuinely offsetting their emissions.
• Moral Hazard: Critics suggest that offset programs may lead to firms simply paying for the right to pollute, rather than actually reducing emissions in their operations.

Conclusion

• Carbon Markets as a Tool for Emission Reduction: Despite the criticisms, carbon markets remain a promising tool for mitigating climate change, provided they are carefully regulated and implemented.
• The Future of Carbon Trading: As discussions at COP29 evolve, the development of international standards for carbon trading could potentially enhance the effectiveness of these markets, offering a viable path to global emission reductions.
