Greenhouse gases (GHGs) are atmospheric gases that trap heat from the sun, thereby warming the planet. The primary GHGs include carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and fluorinated gases. These emissions result from human activities like burning fossil fuels, industrial processes, agriculture, and deforestation. Reducing GHG emissions is essential for mitigating climate change and its associated impacts. International agreements like the Paris Agreement aim to limit GHG emissions globally.
