Blockchain and Carbon Credits: A New Era of Transparent Climate Action

As the world deals with the pressing necessity to reduce the problem of climate change, carbon credits have become a vital tool in the process of balancing the emission of greenhouse gases. Nevertheless, transparency, fraud and inefficiency have been a bane to the traditional carbon credit system.

The potential of the blockchain technology is that it can revolutionize the manner in which carbon credits are issued, verified and traded in the world market with a new level of transparency and accountability.

Carbon credits are considered as the right to emit a single metric ton of carbon dioxide, or otherwise known as greenhouse gases. These financial tools provide economic incentives on how organizations can lower their carbon footprint by imposing a monetary charge on the emissions produced such that firms exceeding their limits will be made to buy more credits, and those producing less than the view of their limits will be able to sell their excess.

There are two major categories of Carbon Credits according to its regulation and the purpose of application.

Compliance-Based Carbon Credits

Compliance-based carbon credits are those which are developed under the legally binding agreements of governments or international treaties. Energy, aviation, and manufacturing industries are required to have certain number of credits covering their emissions as mandated by such regulations as:

• European Union Emissions Trading Scheme
• California Cap-and-Trade Program
• Mechanisms of the Paris Accord

Firms that are over their quota are forced to purchase new credits whereas those that emit less get to sell their surplus credits.

Voluntary Carbon Credits

Voluntary carbon credit is also bought by other organizations and individuals who may wish to offset their emissions due to ethical reasons or reputation. These credits facilitate corporate social responsibility and net-zero commitments.

The Standards of these Markets Standards in these markets are set by independent certification bodies such as:

• Verra
• Gold Standard
• Climate Action Reserve
• American Carbon Registry

These provide flexibility in designing and financing projects. The projects should show additionality, in that without the project, the reductions in emission would not have been made. The cuts should be measurable, cross-verified, long term and without duplication.

Common Project Types

Renewable energy projects will substitute generation of fossil fuel with clean energy of solar, wind and hydro sources. Photosynthesis of carbon dioxide is achieved by reforestation and afforestation programs, which then accumulate it in the biomass and soil.

Methane capture projects do not allow this powerful, greenhouse gas to escape into landfills, agricultural activities, and wastewater treatment plants, but instead convert it into renewable energy.

Soil carbon sequestration uses agricultural methods such as no-till farming, cover cropping, and composting to enhance surface storage in addition to enhancing soil health.

Current systems have major barriers that hinder their effectiveness and credibility due to the absence of transparency in the systems.

Lack of Transparency

Buyers are not suitable to have real-time credit source information about environmental effects and so they are mistrusted and make poor choices. This lack of transparency undermines the trustworthiness of the whole carbon offset market.

Double Counting Issues

When the same offset is asserted by more than one party in more than one jurisdiction, or by a buyer and a developer, then this is known as double counting. This creation of perceived climate benefits and false reporting of global emissions endangers market credibility.

High Transaction Costs

High transaction costs are caused by plenty of intermediaries and bureaucracy that decreases the money that flows to the real environmental projects. This lack of efficiency restricts the size and effectiveness of climate efforts.

Limited Market Access

Access to the market is obstructed for:

• Small businesses
• Grassroots organizations
• Less-developed nations

This occurs through complicated regulations, restrictive entry expenses, and insufficient digital connectivity.

Blockchain technology provides a decentralized digital registry, the information in which is stored reliably, transparently, and impartially. Contrary to the traditional centralized databases, blockchain disperses the information across the computer networks, making them more resilient and trustworthy.

Key Benefits

Transparency is achieved as all transactions are documented on publicly accessible, immutable ledger books. The origin, transfer, and retirement of every carbon credit are transparent in real-time, eliminating multiple and redundant transactions.

Traceability enhances with unique digital identities of each carbon credit, forming complete chains of custody between creation and retirement. This holistic tracking averts double counting and ensures credit authenticity during their lifetime.

Automation enables automated issuance, verification, and retirement of credit with no human error. This IT automation simplifies operations and minimizes administrative delays and corruption.

Decentralization disperses power over networks to minimize reliance on intermediaries and improve system resilience. This system allows wider inclusion whereby smaller organizations and developing nations are included.

Four-Stage Implementation Process

Verification Process

Verification processes utilise real-time data on the environmental conditions through:

• IoT sensors monitoring environmental conditions
• Satellite images tracking land use changes
• Artificial intelligence interpreting collected data
• Independent auditors accessing blockchain platforms directly

Trading Mechanisms

Trading is done on decentralized marketplaces that allow peer-to-peer transactions without central intermediaries. Smart contracts are automated to execute trades once they reach certain conditions and payment flexibility accepts both cryptocurrencies and traditional currencies.

Blockchain implementation benefits the carbon credit system by:

• Removing the potential of double counting
• Offering environmental security to consumers
• Enabling specific features previously inaccessible to the market
• Minimizing fraud and maximizing stakeholder confidence
• Allowing independent verification through automated smart contracts

Economic Benefits

Economies of scale and efficiencies arise from automated smart contracts that manage credit without human intervention. The reduced number of middlemen allows minimal operational expenses, directing more financial resources to real environmental projects.

Increased Access and Inclusion

Decentralized platforms allow anyone with internet access to participate. Smaller projects and local communities can interact without facing costly regulatory overhead, establishing larger equity in climate initiative funding to developing countries.

Global Standardization

Standard protocols coded into blockchain structure enable cross-standard compatibility and interoperability between credits across different methodologies, facilitating efficient international offset markets.

Existing Blockchain Climate Initiatives

Toucan Protocol has created infrastructure involving tokenizing existing carbon credits, connecting traditional markets with decentralized finance via Base Carbon Tonnes. This tokenization increases liquidity and accessibility while maintaining transparency.

KlimaDAO is an autonomous organization that buys and locks tokens to carbon credits, making them inaccessible to create environmental impact. Participants receive governance tokens providing voting rights and monetary rewards.

Celo collaborates with Wren to enable direct investment in verified carbon removal projects. Smart contracts allocate funds automatically to certified projects fighting climate change.

Regen Network uses regenerative agriculture and ecological management to reduce emissions, with credits tied to quantifiable environmental outcomes like soil carbon sequestration and biodiversity increase.

Non-Fungible Tokens (NFTs)

NFTs serve as unique digital representations of individual carbon credits containing:

• Certification-related information
• Project type and origin details
• Verification criteria

This guarantees every credit is tracked, unalterable and resistant to piracy or abuse.

Decentralized Oracles

Oracles link blockchain platforms to external information sources such as:

• Satellite photos
• Weather stations
• Environmental monitoring systems

This provides verified information to smart contracts for correct project validation.

Internet of Things (IoT)
