OSU researchers find small particles from tires inhibit growth of organisms in freshwater, coastal estuaries

Green Car Congress

about 30% of its tread erodes and enters the environment. million metric tons of tire wear particles flow into the environment each year in the United States. Exposure to nano tire particles enhanced toxicity in comparison to leachate alone. The researchers cite studies that show during the lifetime of an automobile tire.

Study finds all-electric rideshare fleet could reduce carbon emissions, but increase traffic issues

Green Car Congress

They used the model and the data to estimate the life cycle air pollution, greenhouse gas, and traffic externality benefits and costs of serving rides based on Chicago TNC trip data from 2019 to 2022 with fully electric vehicles. The authors acknowledge funding from Carnegie Mellon University’s Wilton E. Scott Institute for Energy Innovation.

Chalmers study finds ship exhaust gas scrubbers responsible for up to 9% of certain hazardous emissions into Baltic Sea

Green Car Congress

The Baltic Sea is one of the most polluted sea areas in the world due to the northerly geographic location, natural hydrographic properties, large catchment area and the semi-enclosed character of the brackish inland sea. Comparison of loads (kg/year) of PAHs from direct discharges from ships and atmospheric deposition to the Baltic Sea.

UNICEF: 300M children worldwide breathing air exceeding WHO pollution guidelines by 6x or more

Green Car Congress

Almost one in seven of the world’s children, 300 million, live in areas with the most toxic levels of outdoor air pollution—six or more times higher than international guidelines set by the UN’s World Health Organization (WHO)— according to a new UNICEF report. No society can afford to ignore air pollution.

Emissions Analytics argues that current Pareto-efficient solution for decarbonization would be hybrids, not BEVs, based on do-no-harm

Green Car Congress

Every air pollutant is more than 90% its limit. Do no harm’ means taking a step back from an intervention to look at the broader context and mitigate potential negative effects on the social fabric, the economy and the environment. The Tesla is, of course, zero on all these measures; upstream emissions were ignored in this test.

What Are the Environmental Impacts of Tires

Clean Fleet Report

Is it bad for the environment? According to independent testing and data firm Emissions Analytics , they can be as much as 1,000 times worse for the environment. million metric tons of tire-wear particles are lost to the environment each year, equivalent to 30% of the weight of every tire used in the U.S. — Jack C.,
