  • Trends in global H2 sources and sinks are analysed from 1990 to 2020, and a comprehensive budget for the decade 2010–2020 is presented.

  • The 100-year Global Warming Potential of hydrogen falls in the range 11.6 ± 2.8, according to chemistry-model estimates, through its chemical impact on methane, ozone and stratospheric water vapor. It is therefore important to avoid leakages in a hydrogen economy, to help mitigate climate change.

  • Model simulations show that the observed trends in the seasonal amplitude of methane can be attributed to changes in emissions and the atmospheric sink from reaction with the hydroxyl radical.

  • The record-breaking atmospheric methane growth rates in 2020 and 2021 revealed heightened emissions from inundated areas in tropical Africa and Asia. However, current processed-based wetland models fail to capture emission surges in these regions.

  • Using a global coupled biogeochemistry–climate model and a chemistry and transport model reveals that China’s present-day global radiative forcing is about ten per cent of the current global total, made up of both warming and cooling contributions; if in the future China reduces the cooling forcings, global warming could accelerate.

  • Using both bottom-up and top-down approaches, the record high increase in the methane growth rate in 2020 is attributed mainly to emissions from wetlands, which have been exacerbated by a warmer and wetter climate, and to the reduced atmospheric methane sink, in response to emissions reduction of air pollutants during COVID-19 lockdowns.

  • Transitioning to a hydrogen economy has the potential to mitigate carbon dioxide emissions. The hydrogen leakage rate and the production pathways appear, based on simulations with a global model, as key leverages to reach a clear climate benefit from a large-scale transition to a hydrogen economy.
