Yukon state of the environment interim report 2021 cover

State of the environment reports provide updates on research and monitoring efforts for climate change, air, water, landscape and fish and wildlife in the territory.

The reports also:

  • give early warning and analysis of potential environmental problems;
  • chart the achievement of the objectives set out in the Environment Act;
  • give baseline information for environmental planning, assessment and regulation; and
  • help guide future decision-making.

Under Yukon’s Environment Act, the Minister of Environment must table:

  • a full state of the environment report in the legislature every 3 years; and
  • interim reports in the years in-between.
