Greenhouse gas sink projects in lagoon environments are unlikely to generate voluntary market carbon credits using current methodologies and standards such as VCS, Gold Standard, and so on. The sink of greenhouse gas CO2 in a human controlled Italian lagoon (Human Controlled Wetland or "valle da pesca") can now generate carbon credits for the voluntary carbon offset market, thanks to new PdR UNI 99:2021 (Italian Organization for Standardization) and the Italian National methodology "BNeutral." Since 2013, twelve H.C.W. "valle da pesca" performers have performed the project in four different locations inside and outside the Venetian Lagoon. These locations are in the Italian Venetian Lagoon (UNESCO). Europe, North Italy The balance of autotrophic and heterotrophic activities governs the CO2 sink. The sediment, with its highly active anoxic denitrification and benthic macroalgae production, serves as the primary CO2 storage tank in wetland shallow waters. A chemical and biological approach with multiple parameters has been published. A personalized continuous electronic device data logger installed inside the lagoon records data once per day for 364 days. Reduced light supply due to high turbidity caused by 1) natural meteorological anomalies or bird/fish feeding, 2) fresh water inlet, and 3) low algae presence, can reduce the carbon sink and carbon credit generation.
