About Us


The Office of Sustainable Practices enhances TDEC’s capacity to promote a culture of environmental sustainability, provide technical guidance to business, industry, and other public entities to promote environmental stewardship in an effort to better conserve Tennessee’s natural resources and to fulfill the Department’s mission and vision.

The Office of Sustainable Practices partners and collaborates within TDEC, and with state government departments, and external stakeholders to:

  • Engage ideas with federal, state and local government agencies, non-governmental organizations, and the academic and business community on matters relevant to environmental sustainability.
  • Support community environmental, economic, public health and social goals through pollution prevention, resource conservation, renewable energy incentives, waste reduction and recycling programs, and sustainable building design.
  • Facilitate and promote environmental leadership through recognition programs and partnerships.
  • Implement departmental strategic initiatives and identify innovative, cost effective opportunities for state government to enhance the quality of life for Tennessee citizens and natural environments.
