This land-mark study, conducted in collaboration with UCL, produces the first analysis of the long term demand, supply and prices of carbon credits (carbon offsets) in the Voluntary Carbon Market. The analysis models future demand for carbon credits from over 5000 companies using a range of forecasting approaches. Future carbon credit supply uses satellite imagery, together with detailed spatial and economic modelling, to project the future costs of meeting this demand. The analysis concludes that considerably higher prices are needed to incentivise a large-scale change in land-use away from agriculture towards preserving and restoring forests, and to invest in capturing and storing CO₂ in the atmosphere.
