Cleaner air in port cities, thanks to new trucks
Innovative loan program helped drivers of shipping trucks upgrade models
When most of us think about air pollution, we envision coal-burning power plants and smokestacks puffing out dirty air.
In many coastal cities, however, a large source of air pollution comes from shipping ports.
Container ships and oil tankers are largely unregulated and release vast amounts of pollution. At the Port of Houston, more than one third of the air pollution also comes from roughly 3,000 “drayage” trucks — diesel-fueled heavy trucks that move containers. Much of this pollution comes from older, more polluting models.
Making it easy to upgrade
In apartnership with the Port of Houston and a regional group supporting cooperation among local governments, EDF has helped develop an innovative program that makes it easier for truck owners to buy new, cleaner trucks, to reduce air pollution at the Port.
New drayage trucks are expensive, costing $150,000 or more. But through the Houston-Galveston Area Council Drayage Loan Program, independent truck owners and truck fleet managers working at the Port of Houston can now get grants to partially offset the cost of a new truck.
Goal: Replace hundreds of trucks
The remainder can be financed through low-interest loans. The grants and loans are funded primarily through the Texas Emission Reduction Program (TERP) and the Environmental Protection Agency’s SmartWay program.
The combination of the grants (often paying half the cost of a new truck) and the loans has made this program a popular choice for drivers at the Port. The program is already becoming a model for other ports around the country.
Improving Houston's air
Through this program, we expect to eliminate significant amounts of air pollution near Houston's port, including:
- 1,638 tons of nitrogen oxide
- 26.7 tons of particulate matter
- 239 tons of carbon monoxide
- 3,636 tons of carbon dioxide
Why this program matters:
- Trucks account for 35% of nitrogen oxide emissions at the Port of Houston. Nitrogen oxides are a primary precursor to ozone, a form of air pollution that aggravates asthma and other respiratory illnesses.
- Over 3,000 trucks serve the port, 39% of which are model year 1997 or older.
- Only 6.5% of these 3,000 trucks have the most stringent emission controls.
- In 2007, trucks servicing the Port covered 130 million miles on Houston roads and idled for nearly 4 million hours at Port facilities.
