Study finds pollution emitted near equator has biggest impact on global ozone

Green Car Congress

They found that the increase in ozone burden due to the spatial distribution change slightly exceeds the combined influences of the increased emission magnitude and global methane. Based on their findings, they suggested that emission increases in Southeast, East and South Asia may be most important for the ozone change.

Study finds São Paulo switch from ethanol to gasoline dropped local ozone levels by 20%, increased CO and nitric oxide concentrations

Green Car Congress

A study by a pair of researchers at Northwestern University found that when fuel prices drove residents of São Paulo, Brazil, to switch from ethanol to gasoline in their flexible-fuel vehicles, local ozone levels dropped 20%. Ozone levels are relatively high in São Paulo, with hourly concentrations above 75 and 125 µg m ?3

Northwestern/Princeton study explores air quality impacts of aggressive conversion to EVs

Green Car Congress

This despite evidence that suggests air pollution impacts from the transportation sector exceed those from greenhouse gases. … Thus to fully account for the complexity of changes to air pollution chemistry, emission changes should be used to drive a chemical transport model (CTM). —Schnell et al. Seasons and times of day.

HALO research aircraft measuring the emissions of megacities in EmeRGe project

Green Car Congress

However, emissions do not just remain in conurbations; particles and gaseous pollutants can be transported thousands of kilometers by the wind. The University of Bremen is the scientific base of the international project known as EMeRGe (Effect of Megacities on the transport and transformation of pollutants on the Regional and Global scales).

Study Finds On-Road Transportation Sector the Greatest Net Contributor to Atmospheric Warming Now and in Mid-Term; Power Sector Takes the Lead by 2050

Green Car Congress

In contrast, the industrial and power sectors release many of the same gases—with a larger contribution to radiative forcing—but they also emit sulfates and other aerosols that cause cooling by reflecting light and altering clouds. “We Targeting on-road transportation is a win-win-win.

New international study finds lab testing of diesel NOx emissions underestimates real-world levels by up to 50%

Green Car Congress

The research, led by the International Council on Clean Transportation and Environmental Health Analytics, LLC., For light-duty vehicles, such as passenger cars, trucks, and vans, the European Union produced nearly 70% of the excess diesel nitrogen oxide emissions. A paper on the work is published in the journal Nature.
