Are different configurations of pilot-scale constructed wetlands carbon sources or carbon sinks?

Key Points

• Constructed wetlands can significantly influence carbon dynamics as potential carbon sinks or sources, impacting climate change.
• Key evidence indicates that specific configurations impact carbon balance, with some configurations showing a carbon sink potential of up to 30%.
• Assessment includes pilot-scale constructed wetlands across multiple designs to determine their role in carbon storage.
• Findings suggest a need for optimized configurations to enhance carbon sequestration potential in wetland systems.
