EPA’s New Auto Emissions Standard Will Speed Transition to Cleaner Cars

Katherine E Kerlin — March 22, 2024 - 9:12am

EPA’s new auto emissions standard will speed the transition to cleaner cars, while also addressing consumer and industry concerns, writes ��ϲ��Ͽ� Davis 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 ��ϲ��Ͽ� Davis 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 ��ϲ��Ͽ� Davis 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 ��ϲ��Ͽ� Davis 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

Katherine E Kerlin — January 31, 2018 - 12:26pm

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 ��ϲ��Ͽ� Davis. 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.
