If an offset fails, then the insurance pay-out may be used to improve biodiversity at the same or another site in order to meet the original biodiversity objectives (DEFRA, 2012). In Canada’s “Fisheries Productivity Investment Policy: A proponents guide to offsetting”, letters of credit are required on a case-by-case basis to ensure the completion of offset measures and offset site monitoring over time. Based on a developer’s estimated offset costs, the regulator may request financial surety to cover the direct costs of environmental restitution and any additional expenses that the regulator incurs in the event that the financial security is drawn upon.
