When I compared data from Our World in Data, I saw that the U.S. produces about 14 tons CO₂ per person, while India is closer to 2 tons. The main reason is energy use. Wealthier countries use more electricity, cars, and products made in factories that run on fossil fuels. Developing countries often use less energy but are growing fast. I think countries with high footprints should invest more in clean energy and help others do the same, because climate change affects everyone globally.
