Our Members

ICROA is comprised of the leading global service providers in the voluntary carbon market


ICROA is working with leading academic institutions to understand the drivers of the voluntary market, and to research and demonstrate the additional non-carbon benefits of voluntary offsetting and insetting. For example, our ground-breaking research has shown that that every one tonne of CO2 offset, delivers an average of $664 worth of co-benefits.
