The carbon footprint is the amount of greenhouse gas, primarily carbon dioxide (CO2), emitted into the atmosphere due to human activities. Greenhouse gases contribute to global warming and climate change by trapping heat in the atmosphere.
Activities that contribute to the carbon footprint include burning fossil fuels such as oil, gas, and coal to produce energy, transportation, agriculture, cement production, and other industrial processes. Additionally, everyday activities such as using appliances, lighting, and heating/cooling one’s home also contribute to the carbon footprint.
The carbon footprint is often used to assess the environmental impact of human activities and to identify ways to reduce greenhouse gas emissions and protect the environment.
