Toyota Central R&D Labs develops new ferrihydrite material that effectively removes ozone from air

Green Car Congress

Comparison of O 3. Japan) report in the journal Angewandte Chemie the development of a mesoporous two-line ferrihydrite (2LFh)—ferrihydrite is a widespread mineral composed of iron, oxygen, and water—that could lead to a new generation of ozone filters in electrostatic devices and aircraft applications.

Study finds damage due to premature mortality from PM2.5 decreased >20% from 2008 to 2014

Green Car Congress

GED was calculated for the 3 most recent NEI years: 2008, 2011, and 2014. We do not include damages from morbidity or other pollutants such as exposure to nitrogen oxides (NO x ) or ozone. Second, the analysis tracks damages by economic sector over 3 NEI years, 2008, 2011, and 2014. Tschofen et al. —Tschofen et al.

Sponsors of SAE Study Conclude HFO-1234yf Can Be Used As Low-GWP Global Replacement Refrigerant in MAC Systems

Green Car Congress

HFO-1234yf is a non-Ozone Depleting Substance with a Global Warming Potential (GWP) of 4. In comparison, the current refrigerant, R-134a, has a GWP of 1,430. This new refrigerant is part of a larger platform of low-GWP refrigerants and blowing agents that Honeywell is developing.

MIT study finds including non-CO2 emissions from synthetic aviation fuel in lifecycle analysis of climate impact can lead to decrease in relative environmental merit; need for a holistic analysis framework

Green Car Congress

In the months following a pulse of NO x in the upper atmosphere, ozone production is stimulated causing a short-term warming. The corresponding reduction in CH 4 , which is an important ozone precursor, leads to a long-term reduction in ozone. Many other factors have less quantifiable impacts. —Stratton et al.
