The Importance of Consultation and Engagement in Environmental and Social Impact Assessments

This case study by the International Institute for Sustainable Development (IISD) examines the role of consultation and engagement within Environmental and Social Impact Assessments (ESIAs) for large-scale mining. It provides a framework for integrating stakeholder dialogue across the mine life cycle—from exploration to closure—and highlights specific legal mechanisms such as grievance processes, participatory monitoring, and the pursuit of Free, Prior, and Informed Consent (FPIC) for Indigenous Peoples. The document includes case studies from British Columbia, Canada, and Peru to illustrate the practical application of these frameworks.

• Environmental and Social Impact Assessments (ESIAs) are critical for governments to determine if a mine should be developed and what conditions should be imposed. The document asserts that project approvals should only be granted when there is general community support, which is described as a "social licence to operate".
• Effective consultation and engagement must span the entire mine life cycle. During exploration, stakeholders should be notified and allowed to comment on permits. In the planning phase, engagement should be a "tool for meaningful dialogue" rather than just information dissemination. During construction and operations, ongoing engagement is necessary to maintain trust and identify issues before they escalate into conflicts.
• The report recommends several specific tools to enhance ESIA frameworks: grievance mechanisms to manage complaints early; multistakeholder mechanisms for oversight of management and closure plans; and participatory monitoring, where communities are involved in monitoring environmental issues to build trust and complement government actions.
• For Indigenous Peoples, the document emphasizes the requirement for Free, Prior, and Informed Consent (FPIC) as established by international standards like UNDRIP and ILO Convention 169. It notes that Indigenous Peoples have the right to "give or withhold consent to a project that may affect them and their territories".
• British Columbia, Canada, has integrated FPIC into its ESIA process via the 2018 Environmental Assessment Act. The process requires expressions of consent from Indigenous groups at two specific points: after the readiness period and after the effects assessment and recommendations. While a project may proceed without consent if there is a "compelling rationale", the system provides a strong incentive to obtain it.
• Peru utilizes participatory monitoring committees to reduce conflict between mines and communities. As of 2019, there were 44 such committees. However, reviews by the UN Development Programme identified several challenges, including a lack of baseline data for comparison, insufficient technical support for communities to interpret results, and the risk that community trust is eroded if the mining company provides the logistics and equipment for the monitoring.
• The document highlights specific legal tools in other jurisdictions, such as Ecuador's Ministerial Declaration 109 of 2018, which utilizes public assemblies, environmental education workshops, and public information centres. It also references Mexico's General Law of Ecological Equilibrium and Environmental Protection, which mandates that impact assessment manifests be publicly available and sets specific timelines for public review and comment.
