Target population

The target population for the survey is NAICS based however the questions pertain to a suite of products and services which are part of the Canadian clean technology taxonomy. More on these products and services can be found in the associated technical reference guide (16-511-X).

Instrument design

The questionnaire was developed by the Environment and Energy Statistics Division (EESD), with input from Innovation, Science and Economic Development Canada and Natural Resources Canada, the survey's primary stakeholders. Compared to its predecessor, the Environment Industry Survey, the content has been pared-down to reflect a more focused array of environmental and clean technology products and services. The questions cover the following categories of goods and services:

- Clean energy production
- Management of non-hazardous waste
- Management of industrial air pollution or flue gas
- Monitoring and reduction of greenhouse gas emissions and air pollution
- Industrial wastewater treatment and municipal sewage treatment
- Water management, recycling and treatment of drinking water technologies
- Remediation of ground water, surface water and leachate
- Remediation of soil, sediment and sludge
- Smart grid and energy storage
- Bioenergy and biomaterial production
- Precision agriculture technologies
- Energy efficiency technologies
- Transportation technologies
- Site remediation services and environmental emergency response services
- Energy efficiency and industrial design services
- Monitoring and reduction of greenhouse gas emissions and air pollution services
- Clean energy services
- Water management and efficiency services
- Sustainable resource services
- Transportation services
- Smart grid services
- Environmental employment
- Revenues generated through exports
- Investments


This is a sample survey with a cross-sectional design.

The Generic Survey Universe File (GSUF) is used as the survey frame.

A stratified sample of establishments classified to the 3-digit level of the North American Industry Classification System (NAICS) Canada 2017 and to geographical regions was selected. Respondents from reference year 2019 who reported total environmental revenues and a list of establishments provided by subject matters were selected with certainty.
