The global carbon sequestration and avoided emissions potentially achieved via blue is high (∼3% of annual greenhouse gas emissions); however, it limited by multidisciplinary interacting uncertainties spanning the social, governance, financial, technological dimensions. We compiled a transdisciplinary team experts to elucidate these challenges identify way forward. Key actions enhance as natural climate solution include improving policy legal arrangements ensure equitable sharing benefits; stewardship incorporating indigenous knowledge values; clarifying property rights; financial approaches accounting tools incorporate co-benefits; developing solutions for measuring at low cost; resolving gaps regarding cycles. Implementing operationalizing will achieve measurable changes atmospheric concentrations, provide multiple co-benefits, address national obligations associated with international agreements.
