Study uncovers role of longer-chain unburned hydrocarbon emissions from diesels in London air pollution; calls for regulatory shift

Green Car Congress

The study found that 60% of the winter primary hydrocarbon hydroxyl radical reactivity in London is from those diesel-related hydrocarbons; the authors predicted that the longer-chain HCs contribute up to 50 % of the ozone production potential in London.

HEI study finds London Congestion Charging Scheme shows little evidence of improving air quality

Green Car Congress

The London Congestion Charging Scheme (CCS)—which charged for travel into central London and reduced traffic volume ( earlier post )—has shown little evidence that it improved air quality as well, according to Part I of a new study published by the Health Effects Institute (HEI). —Kelly et al.

HALO research aircraft measuring the emissions of megacities in EmeRGe project

Green Car Congress

The transport and transformation of plumes from selected European and Asian major population centers (MPCs) will now be investigated with special focus on the rate of formation of ozone and aerosols. In Asia, in particular, high temperatures, humidity, solar radiation and the frequency of storms play a major role.

Lancet Series Finds That Cutting Greenhouse Pollutants Will Have Major Direct Health Benefits Worldwide

Green Car Congress

Climate change due to emission of greenhouse gases from fossil fuel energy sources causes air pollution by increasing ground-level ozone and concentrations of fine particulate matter. Black carbon is a short-lived greenhouse pollutant which, along with ozone, is responsible for a significant proportion of global warming.

COVID-19 Forced Us All to Experiment. What Have We Learned?

Cars That Think

To find the upside of emergencies, we first looked at the economic effects of a tidy little crisis, a two-day strike that partially disrupted service of the London Underground in 2014. London commuters found better routes, and Icelandic young people got more schooling and found better places to live.

SCOPE Biofuels Project Releases Assessment on Environmental Effects of Biofuel Technologies

Green Car Congress

SCOPE is part of the International Council for Science. Biofuels based on low input cultivation of non-food crops offers promise in developing countries as a source of energy, in part because energy use is often very low at present. However very few studies include water use impacts. SCOPE symposium on finance, food and energy crisis.
