As the world grapples with the urgent need to combat climate change, a complex and rapidly growing financial tool has taken centre stage: the carbon credits market. For businesses, governments and even individuals, it presents a mechanism to offset carbon footprints. But is it a silver bullet for our climate woes or a controversial loophole?
This article decodes the carbon credits market, exploring how it functions, its real-world environmental impact and the future it holds.
We’ll look at:
- What a carbon credit is and the basics of the market.
- The difference between voluntary and compliance markets.
- The real environmental benefits and critical challenges.
- What the future looks like for carbon trading.
What exactly is the carbon credits market?
At its core, the carbon credits market is a system that puts a price on carbon emissions. It creates a financial incentive for entities to reduce their greenhouse gas output.
A carbon credit is a tradable permit or certificate that represents the right to emit one tonne of carbon dioxide (CO₂) or the equivalent amount of a different greenhouse gas (tCO₂e). These credits are generated by projects around the world that actively reduce, avoid or remove greenhouse gases from the atmosphere.
According to the World Bank, there are two main types of carbon markets:
- Compliance markets (mandatory): These are created by government policies that put a mandatory cap on the emissions allowed in certain industries. Companies that emit less than their cap can sell their excess allowances as carbon credits to companies that exceed their limits. The European Union’s Emissions Trading System (EU ETS) is the largest example of this.
- Voluntary markets: In this market, companies, organisations and individuals voluntarily purchase carbon credits to offset their emissions. This is often done to meet corporate social responsibility (CSR) goals, achieve carbon neutrality or appeal to environmentally-conscious consumers. The voluntary carbon credits market is where much of the recent growth and innovation is happening.
How are carbon credits generated and traded?
The journey of a carbon credit from a project to a buyer is a rigorous one, designed to ensure legitimacy.
- Project development: An entity develops a project that reduces or removes CO₂. Examples include:
- Reforestation and afforestation: Planting new trees that absorb CO₂.
- Renewable energy: Building wind, solar or hydro projects to replace fossil fuel-based energy.
- Methane capture: Capturing methane emissions from landfills or livestock.
- Improved cookstoves: Distributing efficient cookstoves in developing nations to reduce wood burning.
- Verification and certification: The project’s emission reductions must be verified by an independent third party against a recognized standard. Prominent standards include the Verified Carbon Standard (VCS) by Verra and the Gold Standard. This step is crucial for proving the reductions are real, measurable, and permanent.
- Credit issuance: Once verified, the project is issued a specific number of carbon credits, with each credit representing one tonne of CO₂e reduced or removed.
- Sale and retirement: These credits are then sold on the carbon credits market. When a buyer purchases a credit to offset their emissions, the credit is “retired” in a public registry so it cannot be re-used.
The environmental impact: promise vs. reality
The carbon credits market holds immense promise, but a Guardian investigation revealed that it is also fraught with challenges that can undermine its environmental impact.
The promise
- Financing climate action: The market channels billions of dollars into environmental projects that otherwise might not get funded, particularly in developing countries.
- Cost-effective emission reductions: It allows companies to find the most economically efficient ways to reduce emissions, whether within their own operations or by funding external projects.
- Fostering innovation: By creating a financial value for carbon reduction, the market encourages innovation in green technologies and sustainable land management practices.
The critical challenges
The integrity of the carbon credits market depends on the quality of the credits. Several key issues are a source of ongoing debate:
- Additionality: This is the most critical principle. A project is “additional” only if the emission reductions would not have happened without the revenue from selling carbon credits. If a solar farm was going to be built anyway due to government subsidies, the credits it generates aren’t additional.
- Permanence: The climate benefit must be permanent. For example, if a forest funded by carbon credits burns down a few years later, the stored carbon is released back into the atmosphere, negating the benefit.
- Leakage: This occurs when a project in one area inadvertently causes an increase in emissions elsewhere. For instance, protecting a forest in one region might simply displace illegal logging to an unprotected forest nearby.
- Greenwashing: Critics argue that some companies use the carbon credits market as a license to continue polluting, buying cheap, low-quality credits to appear “green” without making meaningful changes to their own business practices.
The future of the carbon credits market
The carbon credits market is at a crossroads. To fulfill its potential, it must evolve. The focus is shifting from quantity to quality, with increased scrutiny on verification and the real-world impact of projects.
Key developments shaping its future include:
- Article 6 of the Paris Agreement: This sets the framework for a global, UN-regulated carbon market, which could help standardise rules and prevent double-counting of emission reductions between countries.
- Technological advancement: New technologies like satellite imagery, AI and remote sensors are making it easier to monitor and verify the impact of carbon projects, especially those related to forestry and land use.
- Demand for high-quality credits: Buyers are becoming more sophisticated, demanding credits from projects that offer verified, permanent carbon removal and co-benefits like biodiversity protection and community development.
Conclusion: A powerful tool that demands integrity
The carbon credits market is not a cure-all for climate change, but it is a powerful and necessary tool in the global decarbonisation toolkit. Its ability to finance vital environmental projects and put a price on pollution is undeniable.
However, for this market to be a credible part of the solution, it must be built on a foundation of transparency, rigour and integrity. As consumers, investors and business leaders, demanding high-quality, verifiable credits is essential to ensuring that the carbon credits market delivers on its ultimate promise: a healthier, more sustainable planet.
