Vehicle miles traveled (VMT) measures the total amount of driving that takes place within the city of San Diego each year. Since transportation is the largest source of greenhouse gas emissions in the city, reducing VMT is one of the most impactful ways to cut emissions.
This indicator tracks total annual miles driven citywide. The targets (green circles) on the chart represent a 19% reduction in VMT by 2030 and a 34% reduction by 2035, both measured against a 2019 baseline.
