Environmental research has often been pursued in response to compliance challenges, as electric power companies have sought the best options for complying with specific environmental regulations. But taking care of the environment goes beyond compliance. Environmental stewardship calls for critical, strategic activity integrated into every aspect of creating and operating a sustainable electric power system. Increasingly, industry leaders' thinking is driven by factors tied to sustainability, which goes well beyond an environmental compliance focus to improved corporate performance in risk management, capital productivity, financial performance, and technology innovation and growth. EPRI's environmental research provides global thought leadership to shape a sustainable future for electricity through collaborative environmental science and technology research. It conducts cross-cutting science and technology research that addresses environmental, health, and economic issues from the generation, delivery, and use of electricity. Research focuses on air, land, water and energy challenges; informs public policy; enables sustainable practices; and improves occupational health and safety.
