Voluntary Carbon Indexes

Price baskets for carbon credit projects.

The GX voluntary carbon indexes module establishes clearer links between carbon credit quality and price - leading to greater liquidity for higher-quality carbon projects and increased transparency in the market to help it scale.

Partnering with global ratings agency BeZero Carbon, we use carbon credit price data for individual projects, then aggregate data provided by BeZero's carbon ratings to create ‘price baskets’ for carbon credit projects. Explore BeZero's individual project ratings here.

Alongside our BeZero partnership, we also provide the market with prices aggregated by scheme, technology and vintage to provide even wider pricing oversight.
