The Commissioner is an independent statutory position established by the Commissioner for Sustainability and the Environment Act 1993.

Our Vision: An environmentally sustainable ACT, region and Australia.

Our Mission: To act as an independent voice for the environment and sustainability in the ACT, and promote community engagement.

Our Values: Transparency, integrity, independence, research, rigour, inclusion.

The Commissioner is an independent statutory position established by the Commissioner for Sustainability and the Environment Act 1993. The Commissioner undertakes the following functions and activities:

  • Investigating complaints about  the management of the environment by the Territory or a territory authority; and issues relating to ecologically sustainable development in the ACT;
  • Conduct investigations as directed by the Minister;
  • Conduct on the Commissioner’s own initiative, investigations into actions of an agency where those actions would have a substantial impact on the environment of the ACT; and
  • Deliver state of the environment reports (SoER).

State of the environment reporting has been one of the main roles of the Commissioner. SoERs have been prepared every four years since 1993.

The Commissioner must take into account the objects of the Act. These are to:

  • ensure regular and consistent reporting on matters relating to the condition and management of the environment in the Territory; and
  • ensure regular reporting on progress towards ecologically sustainable development by the Territory and Territory authorities; and
  • encourage decision making that facilitates ecologically sustainable development; and
  • enhance knowledge and understanding of issues relating to ecologically sustainable development and the environment; and
  • encourage sound environmental practices and procedures to be adopted by the Territory and Territory authorities as a basis for ecologically sustainable development.

Dr Sophie Lewis

Dr Sophie Lewis was appointed as the ACT Commissioner for Sustainability and the Environment on 1 May 2020.

Her most recent role was as a climate scientist at the University of NSW Canberra. She was also a lead author on Intergovernmental Panel on Climate Change (IPCC) reports, which are used worldwide to develop policies around climate change.

Dr Lewis was named 2019 ACT Scientist of the Year in recognition of her research, particularly on weather extremes and how climate change contributes to events such as bushfires and droughts.  In 2015 she was presented with the Australian Meteorological and Oceanographic Society (AMOS) Early Career Researcher Award for her work in climate science.

Her experience will bring a strong focus on climate change given her research background in this field, and her strong knowledge and connection to Canberra.
