Complete carbon credit ratings you can trust

The Sylvera rating assesses the likelihood that the credits issued by a carbon project have delivered on their claims of avoiding or removing one metric ton of carbon dioxide (tCO2) or other greenhouse gases (GHGs).

Bottom-up & Peer-reviewed

The most transparent and in-depth ratings available

We develop specific frameworks for each project category, because it is the only way to accurately assess quality across fundamentally different categories of activities. Simply put, if you evaluate a REDD+ project and Renewables project with a generic framework, the results will be inaccurate. 

All frameworks are peer-reviewed by a committee of experts and carbon market stakeholders – including project developers & registries – to ensure scientific consensus. Then we publish our frameworks so buyers understand exactly what we test and how we do it.

When evaluating individual projects, we meticulously build carbon, strength of baseline and financial additionality models from the ground up with independent and proprietary data.

Sylvera Rating System

Ratings bring transparency to carbon credit quality

Each rating is derived from the holistic analysis of a project's carbon performance, additionality and permanence.

Carbon

Carbon score graph - System UI

Our carbon score verifies whether a project is accurately reporting on its activities, which directly translates to its overall avoided emissions or removals of CO2, and other GHGs.

For AFOLU projects, we confirm the planting of trees and the protection against deforestation by comparing data provided by the project developers with our own measurements using remote sensing data and our proprietary machine learning (ML) models. 

For Renewables projects, Sylvera compares reported generation with third-party, independent generation data from grid operators, energy regulators, and offtakers.

Additionality

We examine whether emissions reductions or removals above and beyond what would have occurred in the “business as usual” scenario have materialized as a direct result of revenue from carbon offsets.

Additionality also assesses the likelihood and severity of over-crediting risk that emanates from inflated counterfactual baseline claims.

Permanence

Permanence score graph - System UI

Combining remote sensing data, climate modeling and project documentation, we evaluate whether the GHG emissions avoided or removed by the project are likely to be maintained for an atmospherically significant period of time.

Co-Benefits

Carbon score graph - System UI

We assess the scope and relative impact of project activities on local biodiversity and communities - which are linked to UN Sustainable Development Goals (SDGs).

The co-benefits score does not feed into the Sylvera Rating, as co-benefits do not have a direct bearing on the climate impact of carbon credits.

LiDAR Satellites

Optical Satellites

E.g. Landsat-7, Landsat-8, Sentinel-2

Multi-Scale LiDAR

E.g. proprietary terrestrial and UAV lidar data

Cutting-edge technology

Sylvera utilizes machine learning (ML) and multiple types of satellite data to identify specific features of forests and land cover. We train proprietary ML models in specific biomes and geographies, which are used to achieve accurate carbon estimates for different project types.

For example, if we are trying to assess forest growth in an afforestation, reforestation and revegetation (ARR) project, we will use ML to estimate the canopy height of trees in the project area (PA). To do this, we train a model to identify forest canopy height by feeding it tens of thousands of labelled data points. Then we run our models on on the PA to estimate the canopy height. By running the model over the same area with data from multiple years, we can see changes over time in the forest area.

Our carbon credit ratings gives market participants confidence to invest in high quality projects that deliver real climate benefits.
