We’ve been told we can be a tough critic and we don’t deny it. We are dedicated to delivering you unbiased, exceptional analysis and unvarnished insights. We are clear on the risks and benefits of a project, so that you can make better decisions for yourself, your company and the planet.
We use peer-reviewed frameworks to analyze both greenhouse gas claim (GHG) integrity and Sustainable Development Goal (SDG) impact. By evaluating and rating GHG risk and SDG impact separately, you can more clearly identify the credits that align with your goals.
Oversight by some of the world’s most experienced climate scientists
Ratings by vintage reflect changes in project conditions over time
Alignment with the Core Carbon Principles of the ICVCM
Greenhouse gas claims evaluated project by project
SDG claims receive the same level of tough scrutiny as GHG claims
Advanced use of remote-sensing and geographic information systems (GIS)
Calyx Global GHG ratings are an assessment of risk that credits do not represent one tonne of removed or reduced CO₂. Our overarching evaluation framework has been peer-reviewed by leading carbon methodology experts and is used to build project type-specific frameworks that ensure consistency in our rating approach.
Our project-level assessments evaluate four risk factors that are consistent with the ICVCM’s core carbon principles:
Additionality
Over-crediting (including baseline, project emissions, leakage)
Permanence
Overlapping claims
The UN adopted 17 Sustainable Development Goals and 169 targets aimed at creating a healthier planet and equitable society. We evaluate and provide a rating for every individual SDG claim made by a project, down to the target level - so you can invest with confidence in carbon credits that support your goals.
Our SDG analysis evaluates the level of impact achieved and the quality of evidence provided, including:
Level of change achieved
How a project's activities lead to targeted change and impact
Methodology used to monitor SDGs contributions
Quality of reported evidence
Our demanding process delivers carbon credit ratings, insights and analytics to help you make informed carbon credit decisions and navigate the market with greater impact and less risk.
