Environmental Management Accounting System To tack the effectiveness of our environment management initiatives, IRPC has introduced the Environmental Management Accounting System (EMA) which integrates expenses, income, and environmental investment in accordance with the international standard UN2001 to obtain accurate, adequate, and reliable data.
