Many international sustainability systems, including around half of all ISEAL Community Members, require developers to obtain the free, prior and informed consent (FPIC) of indigenous communities affected by their projects. However, there's a lack of experience and practical guidance on what FPIC looks like in practice. An FPIC process that is not conducted and monitored appropriately risks undermining trust between the communities, companies and other stakeholders involved in a project. Part of the challenge is that a robust FPIC process will vary greatly depending on the context and the communities involved.
