EPA’s new auto emissions standard will speed the transition to cleaner cars, while also addressing consumer and industry concerns, writes �ٺ��Ƶ transportation researcher Alan Jenn.

Wildfire, Soil Emissions Increasing Air Pollution in Remote Forests

Emily C Dooley — August 29, 2023 - 2:00am

Nitrogen dioxide levels in remote forest areas are increasang, and wildfire and soil emissions are likely the reasons why, finds a �ٺ��Ƶ study.

Will Knowing a Flight’s Carbon Emissions Change Your Travel Plans?

Katherine E Kerlin — November 17, 2021 - 3:13pm

As more people begin booking flights again, many factors come into play—from price to time of day to number of stops. Last month, Google Flights began adding carbon emissions estimates for flights in its search results.

Research from �ٺ��Ƶ indicates that consumers are willing to pay more to pollute less during flights and that including such emissions information may help green the aviation industry.

Concrete Solutions That Lower Both Emissions and Air Pollution

Katherine E Kerlin — March 23, 2020 - 2:41pm

Sometimes, fixing one problem can create another.

Concrete production contributes 8 percent of global greenhouse gases, and demand continues to rise as populations and incomes grow. Yet some commonly discussed strategies to reduce the sector’s global GHG emissions could, under some scenarios, increase local air pollution and related health damages, according to a study from the University of California, Davis.

Can Seaweed Cut Methane Emissions on Dairy Farms?

Katherine E Kerlin — May 24, 2018 - 11:30am

Seaweed may be the super food dairy cattle need to reduce the amount of methane they burp into the atmosphere. Early results from research at �ٺ��Ƶ indicate that just a touch of the ocean algae in cattle feed could dramatically cut greenhouse gas emissions from California’s 1.8 million dairy cows.

Smog-Forming Soils

A previously unrecognized source of nitrogen oxide is contributing up to about 40 percent of the NOx emissions in California, according to a study led by the University of California, Davis. The study traces the emissions to fertilized soils in the Central Valley region.

Nearly Half of California’s Vegetation at Risk From Climate Stress

Katherine E Kerlin — January 25, 2018 - 3:07pm

Current levels of greenhouse gas emissions are putting nearly half of California’s natural vegetation at risk from climate stress, according to a study led by �ٺ��Ƶ. However, cutting emissions so that global temperatures increase by no more than 2 degrees Celsius (3.2 degrees Fahrenheit) could reduce those impacts by half.

Can Corals Adapt to Climate Change?

Katherine E Kerlin — November 01, 2017 - 4:05pm

Cool-water corals can adapt to a slightly warmer ocean, but only if global greenhouse gas emissions are reduced. That’s according to a study published Nov. 1 in the journal Science Advances of genetic adaptation and the likely effects of future warming on tabletop corals in the Cook Islands.

Helping Water Utilities Reduce California’s Energy Use and Emissions

Katherine E Kerlin — October 19, 2017 - 1:48pm

Over the next three and a half years, researchers at the University of California, Davis, will work with the Moulton Niguel Water District and Helio Energy Solutions to better understand how water utilities can reduce California’s energy use as the state works to meet its ambitious greenhouse-gas reduction goals.

You Say You Want a Transportation Revolution? How About Three of Them?

Katherine E Kerlin — May 02, 2017 - 12:40pm

Three transportation revolutions are in sight, and together, they could help reduce traffic, improve livability, save trillions of dollars and reduce urban transportation CO2 emissions by 80 percent or more worldwide by 2050. That’s according to a report released today from the University of California, Davis, and the New York-based nonprofit Institute for Transportation & Development Policy.

But to receive the most benefit from electric, driverless and shared transportation, the three revolutions must happen at the same time.
