Biogenic Carbon Capture and Storage Methodology- Public Consultation

Rainbow is a carbon crediting standard, and we’re excited to announce a 30-day public consultation on our Biogenic Carbon Capture and Storage methodology. This consultation is part of our ongoing commitment to transparency and collaboration in the development of each methodology.
This methodology was developed by Rainbow with the support of the Rainbow BioCCS Working Group members and other expert contributors.
The goal of this consultation is to gather input from a broad range of stakeholders to ensure the methodology is both scientifically sound and practically applicable. We aim to strike a balance between methodological rigor and feasibility, keeping in mind the real-world challenges that project developers and other stakeholders face.
Thank you for contributing to the future of carbon crediting! 🙏
Why do you have an interest to participate?
✔️ Ensure the methodology meets the scientific rigor needed for issuing high-quality carbon credits
✔️ Ensure the methodology is feasible to implement
How to answer this consultation?
