Health benefits from cleaner vehicles and increased active transportation in Seattle, Washington.

ABSTRACT:

Background

Climate mitigation policies that focus on the transportation sector yield near-term health co-benefits that could motivate policy action.

Objective

We quantified CO₂ emission reductions as well as the air pollution and health benefits of urban transportation policies promoting electric vehicles (EV) and walking and bicycling in Seattle, Washington.

Methods

We compared a business-as-usual scenario projected to 2035 with intervention scenarios in which 35% of gasoline vehicles were switched to EV, and 50% of car trips less than 8 kilometers were replaced by walking or bicycling. We modeled changes in primary traffic-generated oxides of nitrogen (NO_x) and fine particulate matter (PM_2.5) as well as walking and bicycling activity
