Carbon footprint refers to the total amount of greenhouse gas emissions, particularly carbon dioxide (CO2), produced by an individual, organization, product, or activity. It is typically measured in metric tons of CO2 emitted per year or over the entire lifecycle of a product. Calculating and understanding one's carbon footprint is important for identifying and reducing sources of emissions in order to mitigate climate change and contribute to a more sustainable environment. This research area encompasses studies on the impact of human activities on the environment, the development of methods for measuring carbon footprints, and strategies for reducing emissions through energy conservation, sustainable practices, and the use of renewable resources.
