Canadian Greenhouse Gas Measurement Program

Environment Canada's Greenhouse Gas Measurement Program operates a network of stations to accurately measure atmospheric concentrations of greenhouse gases from coastal, interior and arctic regions in Canada. The data collected at these stations is used to:

  • Identify trends; seasonal variability and spatial distribution of greenhouse gases in Canada.
  • Provide a coherent and consistent picture of the present and past states of greenhouse gases in the atmosphere, as a result of changing atmospheric transport patterns, emissions from natural sources, such as from wetlands and forests and emissions to the atmosphere due to human activities, including the burning of fossil fuels.
  • Provide the scientific and policy-making communities with high quality baseline and trend information that contributes to the development and evaluation of mitigation plans and tracks the effectiveness of Canadian and international policies and regulations.

Greenhouse gas measurements began in 1975 and constitute Canada’s contribution to the World Meteorological Organization’s (WMO) Global Atmosphere Watch Program.

This work is integrated with the climate processes research on carbon and water cycles at the Borden Forest Research Station and the Boreal Climate Research sites, as well as aerosol studies at the Canadian Aerosol Baseline Measurement (CABM) Program.
