ICL briefing paper estimates that 52% of all small particle pollution from road transport comes from tires and brakes

Green Car Congress

A new briefing paper from Imperial College London estimates that in 2021, 52% of all small particle pollution from road transport came from tires and brakes. Despite this, research on the environmental and health impacts of tire wear has been neglected in comparison to the research and innovations dedicated to tackling fuel emissions.

Chalmers study finds ship exhaust gas scrubbers responsible for up to 9% of certain hazardous emissions into Baltic Sea

Green Car Congress

New research from Chalmers University of Technology, Sweden, finds that the discharge water from ships’ exhaust gas treatment systems—i.e., Comparison of loads (kg/year) of PAHs from direct discharges from ships and atmospheric deposition to the Baltic Sea.

Two new studies of road air pollution in London find detrimental effects on over-60s and unborn babies

Green Car Congress

Exposure to air pollution on city streets is enough to counter the beneficial health effects of exercise in adults over 60, according to new research led by Imperial College London and Duke University. Our research suggests that we might advise older adults to walk in green spaces, away from built-up areas and pollution from traffic.

Study finds “markedly” high levels of diesel exhaust present in commuter trains powered by locomotives in pull-mode

Green Car Congress

A paper on the study is published in the journal Atmospheric Environment. However, both measurements also act as proxies for the complex mixture of gases in diesel exhaust, which is an established carcinogen and associated with respiratory, cardiovascular and reproductive health effects.

What Are the Environmental Impacts of Tires

Clean Fleet Report

Is it bad for the environment? Marion, OH Most people have heard of exhaust emissions, but there is another form of emissions released by vehicles known as non-exhaust emissions (NEEs). According to independent testing and data firm Emissions Analytics , they can be as much as 1,000 times worse for the environment.

Ricardo demos real-world driving emissions testing at Air Quality show

Green Car Congress

The system uses absorption spectroscopy to monitor and record emissions from a vehicle’s exhaust as it passes by a road-side sensor. This data promises to play an important role in providing cities and local authorities with the insight they need to develop Clean Air Zones and other air pollution mitigation measures.

Study finds high exhaust temperatures within NTE operation for heavy-duty diesels with aftertreatment systems contribute to high nanoparticle concentrations

Green Car Congress

The transient results illustrate the gradual formation of the nucleation mode particles with continuous increase in exhaust temperatures. The particle number count under those conditions increased by more than an order of magnitude in comparison to DPF-out particle concentrations. Credit: ACS, Thiruvengadam et al. Click to enlarge.
