Environmental Protection Agency Research on Vehicle Exhaust
There has been a lot of research conducted on how much black carbon and carbon dioxide are emitted from vehicle exhausts. The results of this research show that vehicle exhaust is a major source of these greenhouse gases. According to the Environmental Protection Agency, the average passenger car emits about 4.6 metric tons of carbon dioxide per year. This means that the emissions from just one vehicle can have a significant impact on the environment. The research conducted by the EPA on carbon dioxide emissions shows that there is a significant problem with emissions from transportation sources. Emissions from cars and trucks account for a large percentage of total emissions, and these emissions are growing at an alarming rate. This research indicates that measures must be taken to reduce transportation emissions in order to protect the environment.
