Question

Explanation:

Walking to work produces no vehicle - related emissions. Carpooling and riding a bus reduce the number of individual cars on the road, thus cutting emissions. Driving a car alone increases emissions. Walking has the least negative impact on air quality among these options as it doesn't rely on fossil - fuel powered engines.

walk to work everyday
