Yukon Environmental and Socio-economic Assessment Board (YESAB) is a neutral, independent, modern land claims–based assessment body. We consider environmental, socio-economic, and cultural effects of proposed projects to support informed decisions about development in the Yukon.
We assess the potential adverse effects of proposed projects and provide recommendations to decision bodies. Our work helps decision makers understand potential impacts before decisions are made.
Our role is to assess — independently, transparently, fairly, and based on evidence.

While this website explains the process, participation takes place through the Online Registry.
YESAB Online Registry (YOR)YESAB is not part of any government department and is not a regulator. Our assessments are impartial, evidence-based, and conducted through a transparent public process.
YESAB was established under Chapter 12 of the Umbrella Final Agreement. Our role supports the implementation of the modern land claims by providing a neutral environmental and socio-economics assessment process.
YESAB looks at more than just technical or biophysical effects. The assessments consider how proposed projects could influence the environment, local communities, regional economies, cultural heritage, and ways of life. This holistic lens helps decision-makers understand the full spectrum of potential impacts.
With Designated Offices located throughout the Yukon, YESAB brings local and regional perspectives into every assessment. This decentralized model ensures the voices of different Yukon communities help shape how projects are understood and evaluated, not just a single central view.
YESAB is revising the rules for evaluations conducted by the Designated Office (DO Rules). These revisions will introduce several changes to the DO evaluation process.
Comments from individuals, communities, organisations, governments, and Yukon First Nations help identify potential effects, local concerns, and opportunities to improve project design. This input becomes part of the public record and is considered alongside scientific information and Indigenous Traditional Knowledge.
Participation is about quality, not quantity. Clear, relevant comments focused on potential effects are the most helpful.
Learn how you can participate in assessmentsProjects are reviewed at one of three assessment levels, based on their scale, complexity, and potential effects.
At each stage, YESAB gathers and analyzes information, invites and considers public and First Nations input, and examines potential environmental and socio-economic effects.
YESAB staff can help explain the assessment process and where to find information.
