The company is committed to contributing to economic and social development of the country and operations are designed to meet at minimum the standards of the Equator Principles and Asian Development Bank Safeguard Policies. In order to monitor the socio-economic development in project affected areas, the Social and Environmental Division (SED) of THPC conducts an annual survey of socio-economic outcomes in villages affected by the Project.
