Cornell University researchers are expressing hope for the future of Houston's breathable air, despite the city's poor rankings in the American Lung Association's 2019 "State of the Air" report.
The report, released in April, ranked Houston ninth nationally for worst ozone pollution and 17th for particle pollution.
Researchers - Percent - Houston - Gasoline - Cars
Researchers say replacing at least 35 percent of Houston's gasoline cars and diesel trucks with electric vehicles by 2040 will reduce pollution and improve air quality by 50 percent.
"The built environment plays a significant role in affecting our daily life and health," said H. Oliver Gao, professor of civil and environmental engineering and senior author of "Potential Impacts of Electric Vehicles on Air Quality and Health Endpoints in the Greater Houston Area in 2040," published in Atmospheric Environment.
Transportation - Mobility - Environment - Health - Gao
"While transportation provides us with mobility, it impacts our environment and our public health," said Gao, who directs Cornell's Center for Transportation, Environment and Community Health and is a fellow at Cornell's Atkinson Center for a Sustainable Future. "We are enjoying this mobility at a very high cost."
Shuai Pan, postdoctoral associate in civil and environmental engineering, along with Gao and a team of chemists and engineers, modeled four scenarios using various levels of electric car adoption to...
