California Assemblymembers introduce bill phasing out gasoline-fueled small off-road engines

Green Car Congress

AB 1346 would require new sales of SORE to be zero-emission by 2024 or whenever the California Air Resources Board (CARB) determines is feasible, whichever is later. Today, operating the best-selling gas-powered commercial leaf blower for one hour emits air pollutants comparable to driving a 2017 Toyota Camry from Los Angeles to Denver.

How Engineers Can Help Protect Earth From Worsening Climate Change

Cars That Think

The climate crisis is also having a severe effect on the planet, which is being battered by pollution, deforestation, and soil degradation. Ninety-nine percent of the global population breathes in air that exceeds WHO-guideline limits on pollutants, with low- and middle-income countries suffering from the highest exposures.

Satellite method provides insight into ozone-NOx-VOCs sensitivity for different locations

Green Car Congress

Ozone pollution near Earth’s surface is one of the main ingredients of summertime smog. Determining effective strategies for mitigating surface ozone (O 3 ) pollution requires knowledge of the relative ambient concentrations of its precursors, NO x , and VOCs. Murray, L. Lamsal, L. Duncan, B., … Tonnesen, G.

Study on Greenhouse Gas Emissions from Global Cities Highlights Importance of Geophysical and Technical Factors

Green Car Congress

An international study of 10 global cities found that a balance of geophysical factors (climate, access to resources, and gateway status) and technical factors (power generation, urban design, and waste processing) determine the greenhouse gas emissions (GHGs) attributable to cities.

Modelling the Impact of PHEVs on Ozone in Denver

Green Car Congress

Researchers at the University of Colorado, Boulder and the National Renewable Energy Laboratory (NREL) modeled the emissions impact had plug-in hybrid electric vehicles (PHEVs) replaced light duty gasoline vehicles in the Denver, Colorado area in summer 2006. Ozone concentration increases were modeled for small areas near central Denver.

Study finds vehicles more important source of urban atmospheric ammonia than farms

Green Car Congress

Vehicle tailpipes are a more important source of ammonia’s contribution to urban air pollution than is agriculture, according to a study by researchers from the US and China. The paper is published in the ACS journal Environmental Science & Technology. They also allowed for more efficient mobile testing. Kang Sun, Lei Tao, David J.
