The legal costs to first create a biodiversity offset and second to transfer the property rights attached to it to the developer in the BioBanking scheme are listed in Table 4.8. Table 4.9 presents aggregate information on known credit prices and the total costs of offsetting development projects, however, it is aggregated, highly variable data and reflects a general scarcity of quality data on offset schemes around the world. Variation in reported values is attributed to local variations in land values, credit scarcity, management costs and risk management costs (ICF GHK and BIO Intelligence Service, 2013). The listed credit prices are not directly comparable as the composition of biodiversity credits differs markedly across programmes.
