Methane Prevention
Every tonne of sargassum intercepted before beaching prevents 302kg CO2-equivalent methane from decomposing biomass. When sargassum beaches and rots, it generates methane and hydrogen sulphide — a potent greenhouse gas with 80× the 20-year warming potential of CO2. Interception prevents this entirely. The credit is immediate, quantifiable, and verified at point of interception.
