 Greenhouse gas emissions are gases that trap heat in the Earth's atmosphere and contribute to global warming. These gases include carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and fluorinated gases such as hydrofluorocarbons (HFCs) and perfluorocarbons (PFCs). The primary source of greenhouse gas emissions is human activities, such as the burning of fossil fuels (coal, oil, and natural gas) for energy production, transportation, and industrial processes. Other human activities that contribute to greenhouse gas emissions include deforestation and agriculture, which produce methane and nitrous oxide. The concern about greenhouse gas emissions lies in the fact that they are causing global warming, which leads to climate change. Climate change can have severe impacts on the environment, including rising sea levels, more frequent and severe weather events, such as hurricanes and droughts, and changes in ecosystems, which can affect plant and animal species' survival.
