Code of Conduct for ESG Ratings and Data Products Providers

Sylvera is committed to maintaining policies and practices that drive the highest standards of independence, integrity, transparency and fairness, whilst ensuring accurate and robust ratings.

Launched on 14 December 2023, an industry-led working group with FCA oversight created the ESG Ratings Code of Conduct. It is grounded in the recommendations published by the International Organization of Securities Commissions (IOSCO), with a focus on promoting transparency, good governance, management of conflicts of interest, and robust systems and controls.

Ratings Frameworks and Framework Review Committee

Sylvera develops market-leading, robust and data-driven Ratings, data, and insights about the carbon markets. The development of each Ratings framework typically takes between 1,500 and 2,500 hours, and each Rating can take in excess of 100 hours to generate.

Sylvera’s frameworks are critical to taking considered, consistent and fair ratings decisions. Each project type is bespoke; we therefore develop frameworks for each project type. You can view all of our Ratings frameworks here.

The Framework Review Committee reviews and scrutinizes all new and materially amended frameworks before adoption. We invite representatives of industry bodies and multilateral institutions; standards bodies; project developers; technical and scientific experts; exchanges and marketplace operators; financial institutions; and buyers/retirees of carbon credits to each Framework Review Committee. Sylvera is also committed to ensuring members of the public can input on its frameworks should they wish, and interested parties are invited to submit comments (including requests to be invited to a Framework Review Committee) to

Whilst decisions on approving and implementing new and amended frameworks are taken by an internal Framework Approval Committee, Sylvera is committed to publishing minutes of each meeting of the Framework Review Committee after each meeting. Click below for the minutes of the meetings held to date:
