The answer depends on what Clean Vision is trying to do AND where they are in the process. It's really hard to understand the PR they put out.
Do they already have a Framework or are asking GT to start there? I assume they already identified Green Projects and assets which is step 1.
"The issuer of a green bond needs to have a document called a “Green Bond Framework,” or “Sustainable Finance Framework,” which lays out the information that is required to demonstrate the integrity of the green label.
This information is often presented using the four core components of the Green Bond Principles: (i) use of proceeds, (ii) selection of projects and assets, (iii) management of proceeds, and (iv) reporting and external review.
Bond issuers are usually very large organizations, so this framework will often describe how existing procedures or governance structures inside the issuer are used as well as any new procedures that have been created."
