From 1986 to 1999, averages in Canada were calculated based on data from 1 to 2 sampling stations. Since 1999, data from 5 sampling stations are used to represent CH4 concentrations. Due to some site closures during the COVID-19 pandemic, data from Canada between 2020 and 2022 were interpolated based on data from the Alert station, which remained active throughout that period. Additionally, due to access issues, data for the Estevan Point (ESP) site was synthesized between 2023 and 2024. Global annual averages are based on measurements from sampling stations that are part of the Global Greenhouse Gas Reference Network (https://gml.noaa.gov/ccgg/ggrn.php).",,,,,,,,,,,,,, "Source: Environment and Climate Change Canada (2025) Climate Research Division, Canadian Greenhouse Gas Measurement Program and National Oceanic (https://www.canada.ca/en/environment-climate-change/services/climate-change/science-research-data/greenhouse-gases-aerosols-monitoring/canadian-greenhouse-gas-measurement-program.html) and Atmospheric Administration (2025) Global Monitoring Laboratory - Trends in 1 930 Atmospheric Methane (https://gml.noaa.gov/ccgg/trends_ch4/).",,,,,,,,,,,,,, Available on the Environmental indicators website (www.canada.ca/environmental-indicators).,,,,,,,,,,,,,,
