New analysis suggests Uber adding significantly to pollution and traffic in European cities

Green Car Congress

Uber is adding more polluting car trips to already-clogged European cities such as London and Paris, new analysis by European NGOs suggests —contributing to air pollution and climate change and exploding the company’s sustainability claims. Uber’s CEO tells us they ‘do the right thing, period.’

Carnegie study finds climate impact of particulates varies greatly depending on where the pollution originated

Green Car Congress

However, while greenhouse gases cause warming by trapping heat in the atmosphere, some aerosols can have a cooling effect on the climate because the aerosol particles cause more of the sun’s light to be reflected away from the planet. In many cases, the strongest climate effects of aerosols are felt far from where the aerosols are emitted.

Study associates long-term exposure to air pollution with increasing emphysema

Green Car Congress

Long-term exposure to ambient air pollutants, especially O 3 (ozone), is significantly associated with increasing emphysema, according to a new study led by the University of Washington, Columbia University and the University at Buffalo. Ground-level ozone is mostly produced when ultraviolet light reacts with pollutants from fossil fuels.

Two-year study in Canada finds large trucks disproportionately contribute to higher levels of black carbon pollution

Green Car Congress

Researchers found that air pollution levels right beside a major trucking route within a city were close to levels seen beside Highway 401, despite the road carrying less than one-tenth of the vehicle traffic. The study is published in the ACS journal Environmental Science & Technology. Shairsingh, Robert M. 8b01914.

Latest GHG Inventory shows California remains below 2020 emissions target; much steeper rate of GHG reductions required

Green Car Congress

The California Air Resources Board released GHG emissions data for 2018 showing that emissions remain below 1990 levels but are effectively flat compared to 2017, while the economy grew by 4.3%. Total statewide 2018 GHG emissions were 425.3 million metric tons between 2017 and 2018, the first such decline since 2013.

Study: ozone levels higher across China than in other countries tracking the air pollutant

Green Car Congress

Many countries regulate ozone because of the damage the pollutant does to plants and people. Since the 1990s, tighter controls on emissions of those ingredients have lessened ozone pollution in many European and US cities. The researchers think the harmful effects of surface ozone pollution are much less recognized.
