Answer:
Carbon footprints differ across countries due to variations in energy consumption, economic activities, population, and climate. Countries with high levels of industrialization and urbanization tend to have higher carbon footprints as they consume more energy and emit more greenhouse gases. Developing countries with growing populations and high poverty levels may also have high carbon footprints due to their reliance on traditional fuels and lack of energy efficiency. Countries with colder climates may also have higher carbon footprints due to the use of heating systems. However, some countries have taken steps to reduce their carbon footprints through the use of renewable energy sources, energy efficiency measures, and sustainable development policies.
