EPA Climate Change Adaptation Plan sees likely increase in tropospheric ozone, with more difficulty in attaining NAAQS in many areas

Green Car Congress

Among the many climate-related vulnerabilities that can impact its mission, the US Environmental Protection Agency (EPA) cites a likely increase in tropospheric ozone pollution as potentially making it more difficult to attain National Ambient Air Quality Standards ( NAAQS ) in many areas with existing ozone problems.

US and UK researchers report direct measurement of key atmospheric reactant; more rapid formation of secondary aerosols

Green Car Congress

succeeded in isolating the simplest CI and reported direct kinetic measurements of its reactions with water, NO, NO 2 , and SO 2. Our results will have a significant impact on our understanding of the oxidizing capacity of the atmosphere and have wide ranging implications for pollution and climate change. Welz et al.

The New Supersonic Boom

Cars That Think

They're preparing prototypes for flight and they've got designs for full-blown airliners capable of carrying scores of passengers. Shortly afterward, the federal government issued a contract to Boeing, which had prevailed over Lockheed and others in a design competition, to develop such a plane.

Perspective: US Needs to Transition to Hydrous Ethanol as the Primary Renewable Transportation Fuel

Green Car Congress

The growth in hydrous ethanol, which uses a blend of 94-95% ethanol to 5-6% water, rapidly increased during the 1980s, with consumption peaking in 1989. water content in it and Gasoline C, or E25, which is a mixture of 75% Gasoline A and 25% in volume of anhydrous ethanol (AEAC) with a maximum of 0.4% 40 CFR ยง 80.27

ICCT finds growth in shipping in Arctic could increase pollutant emissions 150-600% by 2025 with current fuels

Green Car Congress

While that report projected vessel activity, it did not explore the environmental impacts of increased shipping in terms of air emissions or the potential climate impacts from increases in short-lived climate pollutants such as black carbon. The emissions report focuses on the low- and mid-range diversion scenarios—i.e.,

Here, RME show advantages for primary energy and GHG, but disadvantages in terms of acidification, eutrophication and ozone depletion. There is an obvious link between environmental impacts estimated by life-cycle impact assessments and water quality problems described at the regional scale. Source: โ€œAssessing Biofuelsโ€.

Up close and personal with Volkswagenโ€™s e-Golf carbon offset project: Garcia River Forest

Green Car Congress

Emission reductions produced by the project are verified by an approved third party and registered with the Climate Action Reserve (Project ID CAR102 ). In some non-reserve areas of GRF, harvest prescriptions include a hardwood competition reduction treatment that is designed to reduce the prevalence of tanoak trees. Click to enlarge.
