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

Green Car Congress

We do not include damages from morbidity or other pollutants such as exposure to nitrogen oxides (NO x ) or ozone. This critical normalization of pollution damage facilitates comparisons of the pollution intensity of output across time within sector and across the economy within a time period. —Tschofen et al.

OptiFuel finalizing $2.6M DOE grant to demonstrate RNG hybrid line-haul locomotive

Green Car Congress

The program will demonstrate that a suite of commercially available, EPA-rail-certified engines present a near-term, low-risk solution to create an affordable RNG hybrid line-haul locomotive with near zero emissions while simultaneously improving fuel cost by 50%. g/bhp-hr of NOx, a reduction of 400 times. g/bhp-hr of PM.

NOAA Study Identifies Nitrous Oxide as Top Ozone-Depleting Emission in 21st Century

Green Car Congress

Comparison of annual N 2 O ODP-weighted emissions from the 1990s with emissions of other ODS in 1987 and in 2008. Currently, anthropogenic N 2 O emissions represent the largest contribution to ozone depletion. Today, nitrous oxide emissions from human activities are more than twice as high as the next leading ozone-depleting gas.

Study finds fleet switch from PFI to GDI engines will result in net reduction in global warming

Green Car Congress

The EPA GHG program is aimed at reducing tailpipe CO 2 emissions. We estimate ozone and SOA formation potential. Therefore, the secondary organic aerosol and ozone formation potential of the exhaust does not depend on engine technology. engine calibration (spark timing, valve timing, etc.), —Saliba et al.

Abt life-cycle analysis of different Li-ion chemistries for PHEVs and EVs identifies opportunities for improving environmental profile of batteries

Green Car Congress

The study, carried out through a partnership with EPA, the US Department of Energy, the Li-ion battery industry, and academicians, was the first life-cycle assessment to bring together and to use data directly provided by Li-ion battery suppliers, manufacturers, and recyclers. A recent Abt Associates, Inc. times smaller in terms of capacity.
