U of Toronto study finds US electrification of LDV fleet not a silver bullet for tackling climate change in vehicle sector

Green Car Congress

A new study by researchers at the University of Toronto has found that current US policies are insufficient to remain within a sectoral CO 2 emission budget for light-duty vehicles that is consistent with preventing more than 2?°C The paper is published in the journal Nature Climate Change.

Study finds Colorado River Basin’s worst known megadrought was 1,800 years ago

Green Car Congress

An even more intense “megadrought” hit the region around 1,800 years ago, according to a new study published in the AGU journal Geophysical Research Letters. The new study used tree-ring data and other climate records to identify a drought period unmatched in severity by the current drought or other ancient droughts.

New method details contributions of climate change & natural variability to rapid Arctic ice loss

Green Car Congress

A new study finds that a substantial chunk of summer sea ice loss in recent decades was due to natural variability in the atmosphere over the Arctic Ocean. The study, from the University of Washington, the University of California Santa Barbara and federal scientists, is published in Nature Climate Change.

China study connects ozone pollution to cardiovascular health

Green Car Congress

Exposure to ozone, long associated with impaired lung function, is also connected to health changes that can cause cardiovascular disease such as heart attack, high blood pressure and stroke, according to a new study of Chinese adults. The team studied 89 healthy adults living in Changsha City, China, for one year.

Study finds megacity traffic soot can reach high altitudes and be transported over long distances, contributing to global warming

Green Car Congress

A reduction of soot particles through driving restrictions for old diesel vehicles can therefore significantly reduce the health impact, as studies by LfULG and TROPOS have shown based on the low emission zone in Leipzig 2017. Soot is also slowing down efforts to limit climate change by reducing greenhouse gas emissions.

Study: expanding Brazilian sugarcane for ethanol could reduce global CO2 emissions by up to 5.6%

Green Car Congress

Vastly expanding sugarcane production in Brazil for conversion to ethanol could reduce current global CO 2 emissions by as much as 5.6%, according to a new study by an international team led by researchers from the University of Illinois. The carbon-related costs of converting the land to sugarcane fields were included in the analysis.

Study projects future EVs to have 30-70% lower environmental impacts that current EVs when changes to electricity generation are considered

Green Car Congress

Numerous studies have tackled the future environmental impact of battery-electric vehicles; the resulting assessments are highly uncertain. The first is changes to driving patterns due to the introduction of autonomous and connected vehicles. In their study, the team used a Life Cycle Assessment (LCA) modeling framework.
