To investigate if greenhouse gases (GHG) emissions from ponds vary among clear-water ponds with macrophytes and turbid-water ponds with phytoplankton, we measured CO₂, CH₄, and N₂O concentrations and emissions in two clear- and two turbid-water urban ponds in the city of Brussels from June 2021 to December 2023. Differences in  CH₄ ebullitive emissions were observed between clear- and turbid-water ponds but none for CO₂ and N₂O emissions.
