The Story
Cars get cleaner over time due to federal regulation and technological improvements, although the number of cars on the road increases because of population growth. Driving increases to 83.7 million miles per day across the four-county Wasatch Front. The percentage of electric cars, which produce zero tailpipe emissions, increases to 30% through expansion of charging stations, incventives, and other measures.
Results
- 6 tons of emissions (NOx, PM2.5, and VOCs) from vehicles per day in the study area
- 34.9 tons of emissions (NOx, PM2.5, and VOCs) from vehicles per day along the four-county Wasatch Front
