In US conservation banking, the use of federal government money to establish a bank does not preclude its participation in the scheme, but the number of credits allocated for sale is made pro rata according to the level of private funding. A conservation bank that creates ten credits but was financed with 30% federal government money, for example, would only be allocated seven credits for sale, reflecting the proportionate contribution of private funding (USFWS, 2003). In France, the Ministry of Environment, Sustainable Development and Energy has formally recognised the additionality of the habitat banking experiment that was launched in 2008 in Saint-Martin-de-Crau.
