Water as part of the climate solution

(Inside Climate News, 28 Nov 2022) A study from Sweden summarizes the enormous role water plays in climate mitigation, from wetlands that take up carbon to untreated wastewater that emits methane.

The intersection of freshwater and climate is a frequently ignored but critical element of the climate problem, according to a new study from Sweden that explores the link and offers solutions that will help lower emissions. 

Two years in the making, the study, “The Essential Drop to Reach Net-Zero: Unpacking Freshwater’s Role in Climate Change Mitigation,” published by the Stockholm Resilience Centre, identifies forests and freshwater wetlands as a crucial depository of carbon. More than 30 percent of estimated global carbon emissions are sequestered in wetlands. So the need to protect and restore them is urgent. 

“The global water supply is the bloodstream of the Earth and the foundation of any successful mitigation action, since Earth’s climate system and water cycle are deeply intertwined,” said  Malin Lundberg Ingemarsson, program manager at the Stockholm International Water Institute and the study’s lead author. “Ours is the first-ever summary of current research on the role of water in climate mitigation.”
