APS adopted its first environmental policy in 1973. Over the past 35 years, compliance with environmental regulatons and environmental stewardship has been a core value for the company. During that time, our policies have evolved to keep up with our current thinking and our commitments to the environment. In 1994, APS joined the Coalition for Environmentally Responsibility Economies (Ceres) and incorporated their enironmental pincipals for environmental stewardship and protection into our policy. Listed below are links to critical aspects of our EHS policy, organization and management systems.
