Web3 Carbon Database

ECOTA is a research-based organization that aims to provide industry stakeholders, policymakers, and the general public with the best possible knowledge about Regenerative Finance (ReFi) with a focus on tokenized carbon claims – whether these take the form of carbon offsets, insets or emission reports. We want to add value to the industry in a neutral and fact-based manner. In cooperation with, we analyzed the current digital environment assets space, focussing on projects that work in the carbon tokenization value chain.

This database is the culmination of the working group "Ecosystem Analysis" that took place from January – October 2023 in cooperation with

Our contribution

Why we're open-sourcing this database

Promote Collaboration

Open-sourcing findings allows various stakeholders including developers, environmentalists, and organizations to collaboratively contribute to and refine the knowledge base, tools, or solutions that have been developed. This collaborative environment can lead to enhanced innovations, improvements in carbon credit tokenization technologies, and the development of new solutions to existing problems in the carbon market, ultimately driving the overall progress of carbon emission reduction efforts.

Enhance Transparency and Trust

In the carbon credits market, trust and transparency are paramount. Open-sourcing findings provides a transparent view of the data, methodologies, and results, allowing for open scrutiny and verification of the information presented. This transparency can help in establishing trust among the users, regulators, and participants of the carbon credit ecosystem, which is essential for the growth and acceptance of tokenized carbon credits.

Foster Education and Awareness

By sharing knowledge and findings openly, a wide range of individuals and entities can access and learn from the information available. This can help in raising awareness about the importance and potential of tokenized carbon credits in mitigating climate change. Educating a broader audience can empower more participants to join the efforts in reducing carbon emissions and can lead to a more informed and engaged community, contributing to the global goal of environmental sustainability.

Target group

Our target groups


What is this working group all about?

We're glad that you asked! That's why we wrote a short & sweet intro to our working group as a paper that you can view here.

What is the scope of this study?

In the creation of the database focusing on the tokenized carbon credits space, each segment of the value chain was categorized to provide users a comprehensive understanding of the lifecycle and facilitation of carbon credits.

The scope included Financing, (d)MRV (Monitoring, Reporting, and Verification), Tokenizing, Trading, Retiring, and Other, each serving a distinctive role in the carbon credit transaction process.

By including these segments, the database offers a multifaceted view of the tokenized carbon credit ecosystem, enabling users to explore, understand, and participate effectively in this evolving market.

What about the blank cells in the database?

Nice catch! You found a cell where we were not sure about what to accurately incorporate into the database. We decided to keep these cells blank.

Do you have a suggestion for the blank cell? Happy to hear from you at

How are the value chain label defined?

A comprehensive overview of the labels used can be found in this document.

Why is my project not listed or information not updated?

The Web3 Carbon space is evolving fast. We did our best to encompass all available data at the time of launch.

If we missed your project or inaccurately represented some data about your project: We would love to get your feedback through this form so that we can update the table constantly. We plan on updating this table quarterly.

Can I use your database in my work?
