Why Are Carbon Credit Registries Entering Blockchain?

As the world is heading to an ecological catastrophe, global organizations and governments are getting increasingly concerned about ways to reduce carbon emissions and control the carbon footprints of plants, factories, industrial facilities, and business entities. Eco-friendliness and sustainability are at the forefront of everyone’s agenda today, and the answer to the problem of mounting CO2 emissions is carbon offsetting.

The principle behind carbon offsets is as follows: a company or individual plants a forest and calculates the volume of CO2 this plantation will sequestrate in the coming years. These are the credits they can sell to businesses producing CO2 emissions, “selling” the right to pollute the environment at the amount of CO2 their forests can absorb. This way, carbon offsetting is seen as an innovative way to compensate for CO2 pollution. The idea got immensely popular, with the present-day carbon credit market valued at $87.9 billion in 2022 and heading to $2.7 trillion by 2028.

But the catch is that there’s virtually no centralized overseeing authority that would verify the value of every carbon credit sold in the carbon offsetting market. Does the seller indeed compensate for the sold number of metric tons of CO2, and how can this activity be measured? That’s where carbon credit registries enter the equation, offering a transparent and fair way of monitoring the carbon credit market. Here, I dwell on the role of carbon credit registries in the emerging GreenFi system and examine the potential gains from its gradual migration to blockchain.

What Are Carbon Credit Registries?

A carbon credit registry is a platform or database responsible for issuing carbon credits in line with specific certification requirements. The registry keeps a record of available offsets and guarantees the validity and transparency of all credits bought and sold in the market. This way, registries are trustworthy mechanisms for tracing the full carbon credit lifecycle, from its creation to retirement, which prevents the possibility of fraud or double counting.

The most widely used carbon credit registries are as follows:

• American Carbon Registry (ACR).
• APX Inc. – a company administering the Gold Standard Registry and Climate Action Reserve (ACR).
• Markit – an entity administering the Social Carbon Registry and Plan Vivo Registry.
• Verra is a platform administering the Verified Carbon Standard (VCS) registry and the Climate, Community, & Biodiversity Standards (CCBS) registry.

Here is an example of how a carbon credit registry works. Once the project developer issues carbon credits, it submits the latter for verification and validation by a reliable third-party registry. The registry’s auditors inspect the project’s background and double-check that the project indeed conducted the mitigation activities it claims to have completed, thus backing the CO2 credits it wants to sell. If the check is successful, credits get verified and get into the carbon credit trading system, where market participants can buy them. After the credit’s purchase and use, the carbon credit gets retired – that is, removed from the registry to avoid double sales.

What Is the Role of Carbon Credit Registries in the GreenFi System?

At present, carbon offset registries represent the backbone of the GreenFi market, as they are the ultimate authorities guaranteeing transparency, trust, and efficiency of carbon trading activities. The carbon market’s accountability is guaranteed with registries that perform the following functions:

• Enable effective carbon credit trading.
• Standardize CO2 measurements.
• Confirm emissions reductions achieved within mitigation activities of carbon credit issuers.
• Prevent double counting.

Due to these essential functions in the carbon market, registries act as vital guarantors of compliance among all market participants and commitment to realistic environmental improvements.

Challenges & Current State of Blockchain Integration

It’s not a secret to anyone that the present-day carbon credit market experiences many challenges. It grows very quickly due to the pressing demand for CO2 offsets; yet, it is immature and non-transparent, which undermines its mission and causes many participants to question its legacy.

Here are the main complexities the carbon credit sphere is yet to overcome and potential solutions to these issues that blockchain promises.

#1 Transparency and Access to Data

Most carbon credits are traded in a non-regulated, decentralized market where the buyer can rarely access the full information about carbon credits’ origin and history. Without rigorous verification, carbon credits are often empty and unsubstantiated, becoming a monetization tool instead of a tangible environmental protection technique. Blockchain promises to solve this problem by giving universal access to each carbon credit’s origin and implementation of mitigation activities in the public ledger.

#2 Duplication

The problem with the current carbon credit market is double counting; as there is no system of unique labeling for carbon credits, some of them are resold many times. This way, no effective offsetting takes place, with the carbon credit seller getting unfair revenue with no sizable environmental improvement. With blockchain, all carbon credits are assigned unique codes and traced on the blockchain, which removes the ability to sell one unit several times on various carbon credit marketplaces.

#3 Environmental Efficiency

There is a lack of consistency in evaluating the efficiency of carbon offsetting projects. In other words, there is no comprehensive system for ensuring that an offsetting project indeed compensates for the specified number of metric tons of CO2. Blockchain may help solve this issue by creating an immutable, distributed tracking system for ineffective mitigation activity identification and removal from the carbon offset market.

#4 Costs of Running the System

Issuance of carbon credits and their trading are currently slow and costly. Market participants need to engage in lengthy red tape to complete the transfer of carbon credit ownership. This issue can be easily addressed with blockchain solutions, as on-chain transactions are quick, cheap, and efficient due to the use of smart contracts.

#5 Carbon Credit Quality

Since many carbon offsetting projects lack credibility and have vague origins, investors may grow distrustful of this market. Blockchain removes this problem by storing exhaustive information about every project and providing real-time, traceable data about its quality.
