Quality Management System Commitments to energy efficiency initiatives can be included in QMS ISO

Quality Management System Commitments to energy efficiency initiatives can be included in QMS ISO 9000 and ISO 14001 QMS are effective in the implementation of energy efficiency program since the QMS has; • Procedures • Continuous improvement • Corrective and Preventative Actions • Root Cause Analysis 18

Energy Efficiency and the Environment The wise energy use help protect the environment •

Energy Efficiency and the Environment The wise energy use help protect the environment • Reduce carbon dioxide (CO 2)emissions • CO 2 is the key greenhouse gas responsible for global warming • CO 2 emissions comes from burning fossil fuels, such as oil, coal and gas • Burning fossil fuel causes emissions of other greenhouse gases, such as • Methane (CH 4) and • Nitrous oxide (N 2 O) 19
