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.
Switching to a more sustainable diet could halve food-related emissions in cities such as Amsterdam, while in cities such as Dhaka and Delhi, the focus should be more on making food production more sustainable as they widen ...
