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.

U Toronto study measures GDI emissions in urban near-road environment

Green Car Congress

A study of emissions from gasoline direct injection (GDI) vehicles in an urban near-road environment in Toronto over a wide range of weather conditions (February 2014 to January 2015) found that—other than for NO x and CO—the GDI engines had elevated emissions compared to the Toronto fleet. —Zimmerman et al.

Study finds total PM10 emissions from EVs equal to those of modern ICEVs; role of weight and non-exhaust PM

Green Car Congress

A new study by a team from the University of Edinburgh and independent engineering company INNAS BV has found that, when factoring in the additional weight and non-exhaust PM factors, total PM 10 emissions from electric vehicles (EVs) are equal to those of modern internal combustion engine vehicles (ICEVs).

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.

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

Green Car Congress

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. Tire wear particles pollute the environment, the air we breathe, the water run-off from roads and has compounding effects on waterways and agriculture.

bp begins shipping LNG from Mozambique’s first LNG project and first FLNG platform

Green Car Congress

These technologies integrate and they are aimed at decreasing the energy used to liquefy the gas and minimizing the impact on the environment, which places Eni’s FLNG ship above the benchmark in its sector in terms of energy efficiency.

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.
