Analysts Say Speeding Up Border Crossings Could Help Slow Climate Change
Environmental analysts from both sides of the US Mexico border say reducing border wait times could help combat climate change in the San Diego Tijuana region.

Environmental analysts from both sides of the US Mexico border say reducing border wait times could help combat climate change in the San Diego Tijuana region.

San Ysidro is the busiest border crossing in the world.

In fact, San Diego Association of Governments officials say 10-percent more people cross the San Ysidro border annually than use Los Angeles International Airport.

Officials say approximately 15-percent more people pass through Otay's Port of entry than San Diego's Lindbergh Field.

Elisa Arias who's an urban planner with Sandag says expanding border crossings, adding technology and improving public transportation would help combat the environmental consequences of the nearly 80-million people who cross every year.

"We should be able to process vehicles, pedestrians and also commercial vehicles faster reducing the border wait times and at the same time reducing idling which is one of the factors in greenhouse gas emissions."

Its not clear how much carbon dioxide vehicles emit at the border.

Experts say on average a commercial truck burns a gallon of fuel an hour while idling.
