Natural climate solutions (NCS), such as wetland protection and restoration, offer significant potential to mitigate climate change by sequestering billions of tons of CO₂ globally. Despite this, wetlands are notably absent from Canada’s greenhouse gas (GHG) inventory, highlighting a critical gap in climate reporting. This omission has driven research into wetlands as NCS, emphasizing two primary strategies: retaining intact wetlands to prevent carbon loss and rewetting drained wetlands to restore carbon sequestration capacity. Temperate inland wetlands are promising due to their substantial CO₂ sequestration potential, though their concurrent methane (CH₄) emissions complicate their efficacy as long-term climate solutions.
This study highlights the role of wetlands as both short- and long-term NCS, emphasizing the importance of incorporating climate-induced changes into wetland-based climate strategies. Effective policies must balance the benefits of wetland retention and restoration with targeted approaches to mitigate CH₄ emissions, ensuring the long-term viability of wetlands as critical components of global climate solutions.
