Normally a polluted waterbody is contributing to GHG emission like any other pollution source like industries, vehicular pollution, mines and cement production plants. The normal course is absorption of oxygen from air for trying to maintain the dissolved oxygen level and emission of carbon dioxide, monoxide or methane. But this is only when the aqua-ecology is disturbed badly due to anthropogenic activities like addition of sewage & industrial effluent.
When the Waterbody is Rejuvenated Ecologically through Cownomics Technology, the natural aqua-ecology is Resuscitated and the aqua-photosynthesis is back in action. This transforms the Waterbody into a Blue Carbon Sink, in which tonnes of atmospheric GHG gets absorbed and fixed in the wetland ecology.
