Developed and operated by a private firm called the Environment Bank, the Environmental Markets Exchange is an information repository for developers and planners to search for sites that meet their offsetting requirements (The Environment Bank, 2014). In addition to offset supply information, the Wetland Database and Reporting Tool in Alberta’s Wetlands Policy provides the public with information on the regulatory approvals process and the links between offset sites in the database and the corresponding biodiversity loss sites (Alberta Government, 2013). Offset registries are therefore particularly important for sites which will be used to supply offsets to multiple projects.
