Official definition

This industry comprises establishments primarily engaged in providing advice and assistance to businesses and other organizations on environmental issues, such as the control of environmental contamination from pollutants, toxic substances, and hazardous materials. These establishments identify problems (e.g., inspect buildings for hazardous materials), measure and evaluate risks, and recommend solutions. They employ a multidisciplined staff of scientists, engineers, and other technicians with expertise in areas, such as air and water quality, asbestos contamination, remediation, ecological restoration, and environmental law. Establishments providing sanitation or site remediation consulting services are included in this industry.

Which code does this activity belong in?

Environmental consulting services focus specifically on environmental contamination, hazardous materials, and ecological issues, distinguishing them from management consulting services that address strategic planning, organizational structure, marketing, and human resources. Environmental consultants identify contamination problems, assess risks to health and ecosystems, and recommend remediation or control solutions using specialized scientific and engineering expertise. Management consultants, by contrast, advise on business operations and strategy rather than environmental quality or contamination control.
