Environmental Impact Assessments

Environmental impact assessments incorporate primary and secondary data to evaluate potential socio-economic and environmental impacts from proposed project activities. As part of the EIA process IEM outlines prevention and mitigation measures for identified impacts and designs a protection and management plan to ensure compliance with existing Thai legislation, other relevant legislation or regulations, and company directives.

The following is a selected list of recent EIAs undertaken by IEM:
