PowerSeraya obtained ISO 14001 certification in 2005 having put in place a robust Environmental Management System (EMS). Under the EMS, the company is required to identify all the environmental aspects of the entire business operations. The environmental impacts for each and every aspect is identified and assessed before it is entered into the Significant Environmental Aspect Register.
Action plans encompassing procedures, mitigation measures and target objectives are then drawn up for every significant environmental aspect for control purposes and subsequently for implementation. The environmental aspects and their associated actions plans (see Table 7.1) are communicated to all relevant staff.
For monitoring purposes, environmental indicators are tracked against objectives and reported on a monthly and quarterly basis at the department/group and senior management levels respectively. On an annual basis, a management review of the environmental objectives and EMS procedures is conducted as part of the continuous improvement cycle.
