How are environmental impacts checked?
Every data centre project in Alberta must earn environmental approvals with legally binding conditions before it operates, and it must keep meeting those conditions for as long as it runs. Much of the public debate turns on one specific tool with a famous name: the Environmental Impact Assessment. This page explains what that tool is actually for, and walks through the checks that apply to every project, every time.
The Alberta approach
No special treatment
Data centres and the power plants that serve them are assessed under the same environmental laws as every other industrial development in Alberta. No shortcuts, no exemptions, and binding conditions that follow the project for its entire life.
Section 1
The checks that apply to every project, every time
Whatever else happens, no data centre power plant operates in Alberta without clearing these hurdles.
An environmental approval with teeth
Power plants require approval under the Environmental Protection and Enhancement Act. That approval carries legally binding conditions, requires public notice, and gives people who are directly affected the right to file a statement of concern and, later, to appeal to the independent Environmental Appeals Board.
Air quality, proven in advance
Before approval, a company must model its emissions using Alberta's required methods and demonstrate they stay within Alberta's Ambient Air Quality Objectives at every location around the site, including the nearest homes, under every operating scenario: normal running, startup and shutdown, emergency backup power, and equipment testing.
Water, licensed and limited
Any water use requires a Water Act licence, junior to every existing user. How do data centres use water?
Noise, with enforceable limits
Provincial noise rules set enforceable sound limits at the nearest homes, with a complaint process that does not expire when construction ends.
Local conditions
Lighting, visual impact and site conditions are set by municipalities through development permits.
Did you know?
Before a power plant is approved in Alberta, the company must prove with modelling that its emissions stay within Alberta's air quality limits at every nearby home, under every operating scenario, including emergencies and equipment testing.
Section 2
So what is an Environmental Impact Assessment, and when is one required?
An Environmental Impact Assessment is one specific tool in Alberta's environmental toolbox. The law reserves it for projects whose effects are genuinely uncertain: new or complex technology, impacts that are hard to predict, or cumulative stress on a region. Some project types trigger it automatically under regulation. For everything else, Alberta's environmental regulator decides case by case, and the Minister of Environment and Protected Areas holds the legal power to order a full assessment of any project, at any time.
That logic applies to both halves of these projects. Natural gas power generation is a technology Alberta has operated and regulated for decades, and its impacts are well understood. The same is true of the data centre itself: at its core it is a building full of computers, infrastructure the world has been building and running since the early 2000s. Neither half involves new or poorly understood technology, which is why these projects are generally assessed through the standard approval framework in Section 1 rather than the EIA process. The scrutiny does not disappear; it arrives through the approval that every plant must earn, with binding conditions and appeal rights attached.
The practical summary: an EIA is a tool for uncertainty, and the absence of one signals that a technology is well understood, with its review running through the standard framework instead.
Did you know?
Skipping a formal Environmental Impact Assessment does not mean skipping environmental review. Every data centre power plant still needs an approval with legally binding conditions, public notice, and the right to appeal.
Section 3
What about the cooling chemicals?
The cooling systems in modern data centres are sealed, like a vehicle's radiator. The coolant, typically a mixture of water and glycol, circulates inside a closed loop and is not released to air, land or water in normal operation. Storage and handling of industrial fluids on site are regulated the same way they are at any other industrial facility, with spill prevention and reporting requirements.
Section 4
After opening day
Approval conditions do not retire when the ribbon is cut. Companies must monitor and report against their conditions for as long as the facility operates. Inspectors verify, with priority set by risk, self-reported data and public complaints. And Alberta publishes its environmental compliance and enforcement records, so you can look up any facility's record yourself.
Section 5
Raising a concern
If a project near you is seeking an environmental approval, the applicant posts public notice, and filing a statement of concern during the notice period preserves your right to appeal the decision to the independent Environmental Appeals Board. For noise, the complaint process runs through the Alberta Utilities Commission, as the utilities regulator, at any point in the facility's life. Alberta wants it to be easy for you to know these rights and use them.

When an EIA is mandatory. Alberta regulation lists project types that automatically require assessment. Beyond the list, the regulator weighs prescribed triggers, unclear impacts, new or complex technology, and cumulative effects, and the Minister of Environment and Protected Areas can order an assessment of any project under the Environmental Protection and Enhancement Act.
Industrial carbon pricing. Large industrial emitters in Alberta, including power generation, fall under Alberta's industrial carbon pricing system.
Wetlands. Alberta's Wetland Policy requires avoidance first, minimization second, and replacement where impacts cannot be avoided. See the water page
