York study: Less traffic in first UK lockdown reduced NO2 pollution but caused increase in surface ozone

Green Car Congress

Less traffic on the roads during the first COVID-19 lockdown in the UK led to a reduction in air pollution but may have caused potentially damaging surface ozone levels to rise, according to a new study led by researchers at the University of York. These results are a cautionary tale. —Professor Lee.

Study finds lead from leaded gasoline persists in London air despite ‘90s ban

Green Car Congress

The study, led by researchers from Imperial College London, found that up to 40% of lead in airborne particles today comes from the legacy of leaded gasoline. The researchers in this study measured lead concentrations of 8 ng/m 3 of air on average during the summer 2018 at Marylebone road. —Senior author Professor Dominik Weiss.

Green NCAP LCA study shows detrimental climate and energy impact of increasing vehicle weight, including EVs

Green Car Congress

Green NCAP tested 34 cars with different powertrain types: battery electric, hybrid electric, conventional petrol and diesel, and one vehicle, the Ford Puma, that runs on alternative fuel. The LCA calculations used the interactive Life Cycle Assessment tool that is available for consumers on Green NCAP’s website.

Ricardo study finds electric and hybrid cars have a higher carbon footprint during production than conventional vehicles, but still offer a lower footprint over the full life cycle

Green Car Congress

The study found that some of the CO 2 savings made during the use of low carbon vehicles is offset by increased emissions created during their production, and to a lesser extent, disposal. —Ricardo Chief Technology & Innovation Officer and Chairman of the LowCVP, Prof. Neville Jackson.
