Stuttgart, Home Of Porsche & Mercedes, Has Banned Older Diesels — #CleanTechnica Report

April 5th, 2019 | by Dr. Maximilian Holland

Every diesel vehicle over 10 years old is now effectively banned from operating in any part of the entire city area of Stuttgart, home to Porsche, Mercedes-Benz, and 630,000 residents. The move signals the first serious diesel ban in any German city. A mid-year review of the resulting pollution rates will decide if many of the remaining diesels, older than 5 years, will also be banned from


The Pros & Cons Of Biofuels

May 23rd, 2018 | by Andy Miles

The burning of any fuel will produce CO2, but also possibly pollution in the form of particulates, nitrogen oxides, sulphur dioxide, and carbon monoxide, although the extent of these depends on the nature of the particular fuel and the efficiency with which the fuel is burnt


68,000 Premature European Deaths A Year From Diesel Vehicle Pollution

March 20th, 2018 | by Nicolas Zart

Volkswagen board members must be wondering how to put away this never-ending diesel scandal, now in its third year. Despite trying its best to avoid the consequences, the auto giant was once again caught a few months back with emission tricks. Adding insult to injury, a German political scandal is brewing from citizens demanding politicians step in ... and many politicians not wanting to step in


Increasing Ozone Pollution In Chinese Cities Raising Mortality Rates, Research Finds

November 30th, 2017 | by James Ayre

The rising air pollution levels in many of China's largest cities are having a pronouncedly negative effect on human health there. Though, that much has been known for quite a while now. A new study, however, has unearthed something not unexpected but still worth taking note of — "robust evidence" that rising levels of short-term ozone exposure are ramping up mortality rates considerably


Emissions Of SO2, NOx, & CO2 Increase Considerably With Each Degree (Celsius) Of Temperature Rise During Summer, Thanks To Air Conditioner Use

May 7th, 2017 | by James Ayre

Owing to the widespread use of air conditioners, emissions of sulfur dioxide (SO2), nitrogen oxides (NOx), and carbon dioxide (CO2) increase substantially during the summer in the US (and surely elsewhere) — air conditioners use a lot of electricity. As global temperatures increase, that means many more people are turning on (and buying) air conditioners, which then increases the electricity production that is a leading cause of global warming.


~20% Of Lorries Operating In Eastern Europe Use “AdBlue Killers” To Defraud Regulators, Research Finds

February 23rd, 2017 | by James Ayre

New research from the University of Heidelberg (commissioned by the German television station ZDF) has seemingly confirmed earlier assertions by the German trade group Camion Pro that a significant fraction of lorries operating in Eastern Europe are utilizing so-called "AdBlue killers" to circumvent the use of the actual NOx-reducing fluid AdBlue while still qualifying for the various tax and toll reductions that vehicles using AdBlue qualify for


London’s Growing Air Pollution Problems Spur New Charge To Keep Heavily Polluting Old Cars Out Of Central City

February 23rd, 2017 | by James Ayre

London's air pollution problems seem to growing rapidly in recent years (or perhaps we should say they are returning, depending on how you think of it). Hourly PM2.5 levels now sometimes exceeding those of Beijing, China. Nitrogen dioxide (NOx) levels have been surging well beyond EU legal limits (over a 5 day period in January, NOx levels exceeded the EU's legal limit for a full year). London was recently put on a "Very High" air pollution alert for the first time


Euro 6 Diesel Cars Emit NOx At Double Rate Of Modern Trucks & Buses

January 8th, 2017 | by James Ayre

In another example of the disparity between the reality of diesel cars and common sales claims, the independent research organization known as the International Council on Clean Transportation has revealed in a new paper that Euro 6 diesel passenger cars emit NOx at over double the rates that modern Euro VI buses and trucks do (on average)
