Greenhouse gases are atmospheric constituents that absorb and emit infrared radiation, thereby contributing to the greenhouse effect and Earth’s radiative energy balance. Major greenhouse gases include carbon dioxide (CO₂), methane (CH₄), nitrous oxide (N₂O), ozone (O₃), and various halogenated compounds, along with water vapour (H₂O) as a feedback agent. Their radiative forcing depends on concentration, spectral absorption properties, atmospheric lifetime, and overlap with other absorbers. In climate research, greenhouse gases are quantified via metrics such as global warming potential and effective radiative forcing to assess their contribution to anthropogenic climate change and to inform emissions mitigation strategies.
As a combustible fuel, the burning of hydrogen gas does not contribute to global warming. Today, the majority of hydrogen gas is generated from fossil fuels, however, and this process releases greenhouse gases into the atmosphere. ...
