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.
Carbon credits allow companies to offset their greenhouse gas emissions through mitigation projects in order to meet voluntary targets, compliance obligations, or national net-zero goals. However, a recent analysis found ...

Photosynthesis is the oldest carbon-capture technology on Earth. For eons, plants have pulled carbon dioxide from the atmosphere and locked carbon—the building block of life on our planet—into their bodies and roots.
