Our Environmental Focus

Environmental Management System

NU's Environmental Management System is a key operational component of the company. It is set of processes and practices that allow NU to identify and address environmental impacts resulting from its services and operations.

This helps the company to anticipate and meet growing environmental performance expectations, mitigate risks, introduce new efficiencies, and enhance its compliance with state and federal regulatory requirements.

This process-driven protocol begins with the identification of the environmental impacts of the activities conducted at NU facilities. These may include air emissions, water discharges, and the company's use of natural resources. Once identified, greater influence is sought over these impacts through the use of operational controls and target goals.

ISO 14001 Certification

NU's Environmental Management System is modeled after the internationally-accepted ISO 14001 standard that provides a logical framework for ensuring a continual cycle of planning, implementing, reviewing and improving our actions to meet environmental expectations and obligations.

The certification requires an annual review by independent auditors of our environmental programs, policies and procedures to ensure that our company continues to act as a leader in environmental management.

NU is proud to have achieved ISO 14001 certification at 44 facilities and departments, including throughout its largest subsidiary, Connecticut Light & Power. Public Service Company of New Hampshire and Yankee Gas Services Company maintain ISO 14001-conformant management systems, and Western Massachusetts Electric Company is expanding its number of certified locations.
