Climate impacts of hydrogen emissionsdlvr.itClimate impacts of hydrogen emissionsNature Reviews Earth & Environment, Published online: 01 June 2026; doi:10.1038/s43017-026-00792-0Although hydrogen is not a direct greenhouse gas, its interactions with atmospheric chemistry lead to indirect climate impacts. This Review discusses sources and sinks of atmospheric hydrogen, including uncertainties and data gaps, and how the warming effect of hydrogen emissions can be estimated and accounted for in policies and standards. 072
