Many adopt the EMS because of market demand.
More buyers require evidence of sound environmental practices from their suppliers.
Others, on the other hand, do so because of regulatory pressures. A good example is the Clean Air Act whose recently signed implementing rules and regulations provide a grace period for companies to conform with stringent environmental safety standards. Whatever the reason, those who have adopted EMS realized that there is profit to be made in adopting environmental standards. This is welcome news for companies as environmental rules are expected to get even stricter. EMS can improve one's business bottom line as it helps improve efficiency, attract customers and gain access to foreign markets.
