Volvo Cars introduces new in-car Advanced Air Cleaner technology; measures PM2.5 inside cabin

Green Car Congress

The company’s new Advanced Air Cleaner technology comes with a sensor that measures PM 2.5 levels inside the cabin, creating a feature not available in any other car currently on the market. This optimizes air quality inside the car, limiting the adverse health effects that are associated with air pollution and fine particulates.

Insight into benzene formation could help development of cleaner combustion engines

Green Car Congress

That insight could also help the car industry make cleaner combustion engines. The industrial processes behind crude oil refineries and the inner-workings of gas-powered combustion engines can emit PAHs, which can form into toxic air pollutants such as soot. Zhao et al.

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

Study finds that replacing older, highly polluting school buses could lead to 1.3 million fewer daily absences annually

Green Car Congress

Replacing all of the oldest, highly polluting school buses in the US could lead to 1.3 Even relatively short commutes on school buses can dominate students’ daily air pollution exposures. The EPA set out to hasten the transition of school bus fleets to cleaner vehicles in 2012 with its School Bus Rebate Program.

NUS researcher links air pollution to increased residential electricity demand

Green Car Congress

The reasons were two-fold: (i) increased air pollution led to households staying indoors more to mitigate the pollution impact; and (ii) PM 2.5 pollution led to the closing of windows, and running of air-conditioners and air purifiers more intensively either to reduce indoor particle levels or provide relief from indoor heat.

SwRI engineers help develop post-refinery diesel treatment that overcomes soot/NOx tradeoff for cleaner burning fuel

Green Car Congress

Internal combustion engines, when burning a fuel-air mixture, produce harmful pollutants such as soot and NO x. Although engine manufacturers routinely develop cleaner engines for new vehicles, older model vehicles continue to contribute heavily to pollution levels.
