International travelers experience adverse cardiopulmonary health effects even after short stay in polluted cities

Green Car Congress

For travelers who visit cities with high levels of air pollution, even a short stay leads to breathing problems that can take at least a week from which to recove, a new study led by researchers at NYU School of Medicine finds. Researchers then compared the health data against levels of air pollution collected from local government agencies.

Insight into benzene formation could help development of cleaner combustion engines

Green Car Congress

That insight could also help the car industry make cleaner combustion engines. The industrial processes behind crude oil refineries and the inner-workings of gas-powered combustion engines can emit PAHs, which can form into toxic air pollutants such as soot. Zhao et al. This work was supported by the DOE Office of Science.

Emissions Analytics: mass adoption of hybrids, rather than low-volume BEVs most effective for cutting CO2 now, meeting 2030 targets; best use of limited resource

Green Car Congress

With automotive battery capacity currently scarce, expensive and suffering supply problems, the deployment of this limited resource is critical to maximizing CO 2 reduction, Emissions Analytics says. It is, however, a false assertion that they are needed to fulfil this purpose.

CMU study finds taxes on emissions would result in more rapid electrification by ridesharing companies

Green Car Congress

When life cycle air pollution and greenhouse gas emission externalities are internalized via a Pigovian tax, fleet electrification increases and externalities decrease, suggesting a role for policy. Air pollution is a classic case where free markets fail. Bruchon, Jeremy J. Michalek, and Inês L. 0c05141.

UNEP and partners launch Global Initiative for Resource-Efficient Cities; role of public transport

Green Car Congress

The United Nations Environment Programme (UNEP) and partners have launched a new initiative that aims to reduce pollution levels, improve resource efficiency and reduce infrastructure costs in cities across the world. In such a rapidly urbanizing world, cities are increasingly becoming the focus of international sustainability efforts.
