Methodology
The CarbonXFuture CPI is a daily-rebalanced, liquidity-weighted composite of the five largest voluntary carbon registry credit benchmarks (VRA, GS, ACR, CAR, Plan Vivo). Weights are re-evaluated quarterly based on 30-day notional traded volume on CarbonXFuture's order book and observable OTC prints from S&P Platts, OPIS and Refinitiv. The index is rebased to 100.00 on 1 January 2025.
