Greenhouse gas emissions refer to the release of gases that trap heat in the atmosphere, contributing to the greenhouse effect and global warming. These gases primarily include carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O). The impact of GHG emissions is significant. These emissions are the primary driver of climate change, which is leading to more frequent and severe weather events, shifts in plant and animal habitats, and rising sea levels, among other effects.
