• The Volkswagen emissions cheating scandal and it's potential impact on VW owners

    Out of the 250 million cars and trucks on U.S. roads, the impending recall at Volkswagen will involve just a half-million of them. But VW's emissions cheating scandal is receiving outsize attention because many of the company's customers feel duped. Now those customers are weighing what it will take to make them feel whole again.

    David Chien of Williston, Vt., was looking for a bigger, fuel-efficient car that could power its way through Northeastern snow. He says the 2013 Jetta SportWagen he bought "seemed to check all the boxes."

  • New England air quality update

    EPA today confirmed that New Englanders experienced a slight increase in the number of unhealthy air quality days this year, compared to 2014 and 2013.

    Based on preliminary data collected between April and September 2015, there were 24 days when ozone monitors in New England recorded concentrations above levels considered healthy. By contrast, in 2014 there were a total of 9 unhealthy ozone days, and in 2013 there were a total of 20 such days.

    The number of unhealthy ozone days in each state this summer is as follows:
    - 22 days in Connecticut (compared to 8 in 2014, and 18 in 2013)
    - 4 days in Rhode Island (0 in 2014, and 7 in 2013)
    - 3 days in Massachusetts (0 in 2014, and 6 in 2013)
    - 2 days in Maine (0 in 2014, and 5 in 2013)
    - 2 days in New Hampshire (1 in 2014, and 3 in 2013)
    - 0 days in Vermont (0 in both 2014, and 2013).

  • The Volkswagen scandal and EU transportation emissions

    The revelations that Volkswagen, the world's second largest car manufacturer, had routinely gamed US emissions testing has thrown the spotlight on the environmental and health impact of cars.

    While EU member states, such as the UK, open or consider investigations into the beleaguered company, European Commission officials are currently reviewing the executive’s 2011 White Paper for transport, its main policy roadmap for the sector.

    Bringing extra impetus to their deliberation is the upcoming UN Climate Change Conference in Paris, international talks aimed at capping global warming.

  • Pesticide use leads to endocrine disrupters in French lettuce

    An investigation has found that the majority of French lettuce contains traces of hormone disrupting chemicals, some of which are banned. Journal de l Environnement reports. 

    The French NGO Générations Futures released the results of an inquiry into chemical contamination in food products on Tuesday (22 September). After examining the contaminants in strawberries in July 2013, the NGO published a report this week entitled EXPPERT 5, examining lettuce, the fourth most popular vegetable in France.

    The findings were less than impressive: of the 31 products bought in supermarkets in the French departments of the Oise and the Somme, grown on conventional farms, over 77% contained traces of at least two pesticides, and only 19% were pesticide-free.

  • Feds Set Food Waste Reduction Goals

    Food waste in the U.S. is a big problem, accounting for about 31 percent of the nation’s food supply, or 133 billion pounds. It makes up 21 percent of U.S. municipal solid waste in landfills, and as a result it accounts for the lion’s share of landfill methane emissions. Methane is a greenhouse gas with a warming potential 21 times that of carbon dioxide — and landfills are the third largest source of methane emissions in the U.S.

  • Diesel cars in the EU having trouble meeting emissions standards on the road

    Every major car manufacturer is selling diesel cars that fail to meet EU air pollution limits on the road in Europe, according to data obtained by sustainable transport group Transport & Environment (T&E). 

    All new diesel cars should have met the Euro 6 autoemissions standard from 1 September – but just one in 10 tested complied with the legal limit. 

    On average new EU diesel cars produce emissions about five times higher than the allowed limit. The results are compiled in a new report, Don’t Breathe Here, in which T&E analyses the reasons for and solutions to air pollution caused by diesel machines and cars – the worst of which, an Audi, emitted 22 times the allowed EU limit.

  • Air Quality in Scotland continuing to improve

    A new report published today shows Scottish emissions of most air pollutants have continued to fall, with significant reductions in emissions of all air pollutants since 1990.

    The announcement of the official figures was welcomed by Environment Minister Aileen McLeod who said an updated action plan to tackle nitrogen dioxide would soon be published.

    Dr McLeod said: “Air pollution is harmful to human health and can contribute to climate change, and I very much welcome the significant progress that has been made reducing emissions of nitrogen oxides and other air pollutants in Scotland.

  • MIT study shows climate change mitigation potential of geoengineering the oceans

    Like the leaves of New England maples, phytoplankton, the microalgae at the base of most oceanic food webs, photosynthesize when exposed to sunlight. In the process, they absorb carbon dioxide from the atmosphere, converting it to carbohydrates and oxygen. Many phytoplankton species also release dimethyl sulfide (DMS) into the atmosphere, where it forms sulfate aerosols, which can directly reflect sunlight or increase cloud cover and reflectivity, resulting in a cooling effect. The ability of phytoplankton to draw planet-warming carbon dioxide (CO2) from the atmosphere and produce aerosols that promote further cooling has made ocean fertilization — through massive dispersal of iron sulfite and other nutrients that stimulate phytoplankton growth — an attractive geoengineering method to reduce global warming.

  • Coastal management strategies in the age of climate change

    Coastal decision-makers must move away from considering physical and economic forces in isolation to fully recognise and explain changes to coastlines, according to new research from Cardiff University.

    The coastlines where we live, work and play have long been altered by people, but now researchers have investigated why developed coastlines change over time in ways that are fundamentally different from their undeveloped, natural counterparts.

  • Climate change mitigation needs more ambitious emissions reductions

    The collective climate targets submitted by Governments to the UN will lead to global emissions far above the levels needed to hold warming to below 2°C, researchers at the Climate Action Tracker warned today.

    The analysis by the consortium of four research organisations was released today in Bonn where Governments are meeting for the second to last week of negotiations ahead of the Paris summit on climate action.
