Bioenergy projects are typically located near the biomass resource, so the pre-existing site is typically not industrial. Early and frequent engagement with the local community is advised to make sure that the change in usage is acceptable to them. Guidelines for engaging stakeholders are included in the RSB Impact assessment guidelines [PDF 708 kb] published by the Roundtable on Sustainable Biomaterials (2011). Guidelines for helping the operator understand the impact assessment process are also included. Beyond the talk: Engaging stakeholders in bioenergy development [PDF 962 kb] is a UNEP bioenergy issue paper.
