Here's a novel idea: rather than installing air quality sensors in fixed locations, why not use mobile sensors to collect data in an evenly spread-out area? OpenSense, a project run by EPFL, a federally funded institute of technology located in Switzerland, and ETH Zurich, a science and technology ...

Back in June of 2010, the picturesque city of London recorded its 36th "bad air" day of the year. That was a problem since European Union (EU) guidelines allow just 35 "bad air" days a year, so reaching that unfortunate level by the sixth month of 2010 meant that London was in violation of the ...

In December of 2010, the city of Beijing, China, announced that it would enforce a measure that restricts vehicle registrations to a mere 240,000, or one-third of the number recorded in 2010. That may sound harsh, but the move is aimed at curbing the city's chronic gridlock and reducing its ...

Rising levels of roadside air pollution plague major cities across the globe. Over in Europe, fine particulate pollution in the cities of Bucharest, Budapest, Barcelona, Paris, Rome and London – to name a few – has been measured at levels exceeding the United Nations World Health ...

The picturesque city of London has recorded its 36th "bad air" day this year after monitoring equipment detected dangerous levels of minute airborne particles. EU guidelines allow just 35 "bad air" days, so reaching this unfortunate level by the sixth month of the year means that London is in ...

Since the beginning of the year, all 2009 model year vehicles (and anything newer, once they're available) sold in California will be sporting a new sticker. No, not the kind that makes your car worth $4,000 more but the kind that describes the vehicle's global warming and smog scores. Just look ...

Move over Los Angeles, the city of Houston, Texas is now also officially on the "severe smog problem" list. The reclassification was requested by Governor Rick Perry last year and the Environmental Protection Agency (EPA) made the change last Thursday. This move from "moderate" bypasses the level ...

Subaru doesn't have any hybrids in its line up and its electric car program, based around the R1e, is still in its (seemingly never-ending) infancy, but it does have partial zero-emission vehicles (PZEVs) and , apparently, pogo sticks. In an effort to promote the sale of its PZEV vehicles in ...

The question of whether or not people should be forced into driving smaller cars with engines that emit less pollutants is one that is likely to be debated for quite some time. Many believe that it is their "right" to drive whatever kind of car they want as long as they are willing to pay for it, ...
