U Birmingham study finds DPFs have limited impact on ultrafine particle emissions

Green Car Congress

A study by researchers at the University of Birmingham in the UK has found that while Diesel Oxidation Catalysts (DOCs) and Diesel Particle Filters (DPFs) has been very effective in controlling the tailpipe emissions of solid particles, there has been little change in the liquid mode ( 104 cm −3 /24-hour mean) defined by WHO.

KCL study finds London air pollution from traffic improving, but continues to exceed limits in many parts of city

Green Car Congress

New research by scientists at King’s College London suggests that air pollution from London’s roads is improving overall but more work may be needed to tackle some sources of traffic pollution, which continue to breach limits in many parts of the city. 15–45%·year −1 ).

Cambridge study of near-term alternative London bus technologies finds lean-burn CNG most costly with greater climate impact than diesel

Green Car Congress

Annual GHG emissions relative to BASE Scenario (BASE Scenario = 949 kt CO 2 e on a 100-year GWP basis) for differing London bus fleet technology options. Their findings indicated that emission control strategy retrofits are the least costly near-term intervention to reduce urban air pollution. Credit: ACS, Chong et al.

Study links ambient PM2.5 and ozone specifically caused by vehicle exhaust emissions to ~361,000 premature deaths worldwide in 2010 and ~385,000 in 2015

Green Car Congress

A new study provides the most detailed picture available to date of the global, regional, and local health impacts attributable to emissions from four transportation subsectors: on-road diesel vehicles; other on-road vehicles; shipping; and non-road mobile engines such as agricultural and construction equipment. of global ambient PM 2.5

London is fighting air pollution; has the time come to upgrade your fleet?

Greenways Insurance

From 8th April 2019, Central London will be introducing an Ultra-Low Emission Zone (ULEZ) to tackle the problem of excessive air pollution in the city. Once this has been initiated, there are further plans to extend this to include the inner London area bounded by the North and South Circular Roads. Avoiding the charge.

Study finds 80% reduction in atmospheric CO as a result of gasoline car emissions policies

Green Car Congress

New research published today (23 May) in Scientific Reports has found a marked and progressive 80% decline in atmospheric CO (carbon monoxide) in SE England since 1997, following adoption of strict controls on gasoline vehicle emissions begin in the 1990s. CO is representative of many pollutants, and London of many northern European cities.
