All types of wetlands are carbon sequestering systems, from temperate freshwater wetlands to boreal peatlands. That means that wetlands have the ability to store excess carbon (via photosynthesis) from the atmosphere – one of the primary components of greenhouse gases and a driver of climate change. “Blue carbon” is the type of carbon that is stored in wetlands. Drainage and degradation of wetlands can release significant amounts of this stored carbon back into the atmosphere and reduce the ability of wetlands to sequester additional carbon. Better management practices can help protect these stores of carbon and the ability of wetlands to sequester it. Wetlands also function as carbon sinks for carbon produced by upland agriculture, forestry and other land uses. As carbon, in the form of organic material (such as eroded soil, leaves, and tree debris), is washed into low lying wetland areas, it is deposited into wetlands where it becomes part of the wetland sediment through decomposition.
