Carbon credits and voluntary carbon market data

Carbon markets are growing and scrutinised in equal measure, and data is central to navigating them. This guide covers carbon-credit and voluntary-market data and how to source it with integrity in mind.

Available across the EU. DataSupplier sources and delivers this data in all 27 European Union countries — including Germany, France, Spain, Italy, the Netherlands and Poland — and across the EEA, in the format and cadence you need.

Why carbon-market data matters

Organisations buying or trading carbon credits need data to assess price, quality and integrity. With concerns about offset quality, transparent data is what separates credible action from greenwashing.

What it contains

• Registry data: issued, retired and transferred credits.
• Project data: methodology, location and vintage.
• Pricing: market and transaction prices.
• Quality ratings: independent integrity assessments.

Common use cases

Procurement and portfolio construction, price and risk analysis, due diligence on project quality, and reporting and claims substantiation.

The integrity dimension

Not all credits are equal, and methodology and additionality questions affect quality. Sourcing should combine registry facts with independent quality data, and document the basis for any claim.

Sourcing considerations

Registries are authoritative for issuance and retirement; pricing and quality come from specialist providers with differing methods. Compliance markets (such as the EU ETS) have their own official data. Licensing and methodology should be confirmed.

In a managed model

A managed partner can combine registry, pricing and quality data into a coherent, documented view for procurement and reporting.

Integrity is the central question

Not all credits are equal, and concerns about quality and additionality mean integrity data matters as much as price. A credible view combines authoritative registry facts (issuance, retirement, vintage, methodology) with independent quality ratings, so a buyer can distinguish robust credits from weak ones rather than treating tonnes as fungible.

Compliance vs voluntary markets

Compliance markets such as the EU ETS have their own official data and rules; the voluntary market is more fragmented, with varying standards and methodologies. Confirm licensing and methodology, and document the basis for any claim, because carbon data increasingly feeds regulated disclosures and public commitments where greenwashing risk is real.
