Environmental assessment is required where the complexity and scale of a proposed project, technology, resource allocation, or siting considerations create uncertainty about the exact nature of environmental effects, or result in a potential for significant adverse environmental effects.

The Environmental Assessment process allows companies and government decision makers to examine the effects that a proposed project may have on the environment. The information gathered during the process helps the appropriate Regulatory Board determine if the project is in the public interest.

As of October 1, 2014, the Alberta Energy Regulator is responsible for environmental assessments related to upstream oil and gas and coal development in the province.

The Alberta government will continue to maintain a single register of all environmental assessment activity information on this website (see Summary of Environmental Assessment Activity).


Assessment information


Federal/provincial cooperation

In 1999, the governments of Canada and Alberta signed a cooperative agreement to avoid duplication and ensure that environmental assessments are conducted as efficiently and effectively as possible.
