Gas emissions refer to the release of gases into the atmosphere, often as a result of human activities such as burning fossil fuels, industrial processes, and agriculture. Common gases emitted include carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O). These emissions can contribute to air pollution and climate change, affecting both the environment and human health. Reducing gas emissions is essential for mitigating climate change and improving air quality. Strategies include using renewable energy sources like solar and wind, enhancing energy efficiency, and promoting sustainable practices in agriculture and transportation. Governments and organizations worldwide are working to set targets and implement policies to lower emissions.
