How does vehicle weight impact emissions?

Heavier vehicles often produce more emissions because they generally require more energy to operate. The increased weight adds to the load that the engine must move, which can lead to higher fuel consumption. When an engine burns more fuel, it typically results in a greater output of carbon dioxide and other pollutants.

This relationship is particularly relevant in the context of fuel efficiency, where lighter vehicles tend to utilize fuel more effectively. The additional mass in heavier vehicles means that they might have to work harder, especially during acceleration and climbing, which contributes to increased emissions. Overall, the impact of vehicle weight on emissions is a crucial factor in understanding vehicle design and environmental policies aimed at reducing pollution.
