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 Approach

The most in-depth ratings available today

We meticulously build carbon, strength of baseline and financial additionality models from the ground up with independent and proprietary data. We believe this bottom-up approach is an essential part of providing quality due diligence, and it’s what sets us apart. We take the same fundamental approach across all our frameworks (REDD+, ARR, IFM, and renewables, among others) so that you can reliably compare credits and make investment decisions with greater confidence.

Following our rigorous process, Sylvera takes between 60-120 hours to develop, test and QA ratings for every individual project. We re-rate projects when new monitoring and verification reports are published. We also update our machine learning data on a quarterly basis.

Ratings bring transparency to carbon credit quality

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

We utilize multiple types of satellite data to train and run our machine learning models.

Synthetic Aperture Radar (SAR) Satellite
E.g. ALOS PALSAR, Sentinel-1
LiDAR Satellites
E.g. GEDI
Optical Satellites
E.g. Landsat-7, Landsat-8, Sentinel-2
Multi-Scale LiDAR
E.g. proprietary terrestrial and UAV lidar data
Cutting-edge technology

Unrivaled machine learning capabilities ensure accuracy

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.

Every project receives an assessment and distinct rating

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

Sylvera only issues a rating when our stringent data requirements are fulfilled

When we don’t have access to all the key data required to evaluate the carbon performance, additionality and permanence of a project, we cannot produce a Complete Sylvera rating. Instead, we issue a report - with the label/grade P for  “Pending” - based on the best data available today. When new data is issued and when it satisfies all our criteria for rigorous analysis, we will reexamine the project and issue a Complete Sylvera rating. Pending grades can be applied to both issuing and pre-issuing carbon projects.
Neutral
Based on data that is available, Sylvera has not identified anything which would negatively impact the subscores.
