In China, how goods are made and bought affects carbon emissions. By looking at different areas within China, experts saw that the way people consume things inside China is the main cause of carbon emissions. Also, the pollution from making things people buy from other countries is growing fast. When they broke down where the pollution comes from, they found that most of it comes from making things that are used to make other things. The increase in pollution is mainly because people are buying more stuff and companies are changing how they make things. The key to reducing pollution in all regions is making production processes cleaner. This shows that to cut down on pollution in China, it's important to balance how things are made and used among different regions.
