AlliedOffsets, a global database and carbon market intelligence provider, and Sylvera, a leading carbon data platform, today announced the release of their groundbreaking Quality-Weighted Carbon Price Index. This comprehensive market intelligence tool seamlessly integrates weekly pricing data based on trading data with scientifically-backed project quality assessments, providing unprecedented transparency and depth of analysis for carbon market participants.
While traditional carbon pricing data has historically focused solely on transaction values, the AlliedOffsets-Sylvera Index addresses a critical market need by correlating price movements with rigorous quality metrics. This dual-lens enables buyers to understand not just what they're paying, but what they're truly getting in terms of environmental integrity and impact.
"The carbon markets have been operating with disconnected information for too long," said Lars Kroijer, CEO and Co-founder at AlliedOffsets. "By combining our leading market pricing data with Sylvera's scientific project assessments, we're giving the market the transparency it needs to build trust, mature and scale effectively."

The index will track critical project categories, each segmented by Sylvera's proprietary quality ratings from premium >BBB to standard:
This segmentation allows market participants to track pricing dynamics within specific quality bands, enabling more sophisticated portfolio construction and risk management strategies across project types.
Updated weekly, the index will be accessible through both companies' platforms, with enhanced analytics available to paid subscribers.
"The aim here is not to create another price indicator – but build the foundation for a more intelligent carbon market," said Allister Furey, CEO from Sylvera. "When project quality and price data work together, it empowers both buyers and project developers to make more informed decisions that drive meaningful climate impact."
The launch comes as demand for high-quality carbon credits continues to surge, with corporate net-zero commitments driving increased scrutiny of environmental integrity. Unlike existing pricing tools that operate in isolation, the AlliedOffsets-Sylvera Index provides the quality context needed for sophisticated market participants to make informed decisions at scale.
The index leverages AlliedOffsets' comprehensive pricing data alongside Sylvera's machine learning-powered project assessments, which analyze satellite imagery, field data, and regulatory documentation to generate objective quality scores. This combination of pricing data and scientific rigour creates a unique market utility.
Data will be integrated into AlliedOffsets' market data dashboard and featured prominently on Sylvera's platform, ensuring broad accessibility across the carbon market ecosystem.
