New Emissions Analytics study suggests pollution from tire wear now 1,850 times worse than exhaust emissions

Green Car Congress

In early 2020, UK-based independent testing firm Emissions Analytics published a study claiming that tire particulate wear emissions were 1,000 times worse than exhaust emissions ( earlier post ). —Emissions Analytics. Quoting such ratios, however, needs careful interpretation.

UCS: ride-hailing trips can produce nearly 70% greater emissions compared to private car trips

Green Car Congress

A new report by the Union of Concerned Scientists (UCS) finds that the rising use of ride-hailing services is increasing carbon emissions, with ride-hailing trips producing nearly 70% greater emissions compared to the trips they are replacing. The error bars for ride-hailing represent uncertainty in the percentage of deadheading miles.

Flying first class on a single domestic round trip can contribute more greenhouse gas emissions than a year of driving

Green Car Congress

This analysis examined the effect of flight distance on greenhouse gas emissions per passenger, and compared emissions from flying different distances with annual emissions from driving. Greenhouse gas emissions were examined for 17 nonstop flights with round-trip distances ranging from 131 miles to 19,040 miles.

Study finds transporting food and ingredients generates 20% of carbon emissions in the global food system

Green Car Congress

A study by researchers in Australia and China has determined that global food-miles account for nearly 20% of total food-systems emissions; moving fruit and vegetables in refrigerated vehicles is particularly emissions-intensive. We estimate the carbon footprint of food-miles by using a global multi-region accounting framework.

CSIRO finds hydrogen could reduce aviation emissions within 5 years

Green Car Congress

A new report from Australia’s national science agency CSIRO shows that clean hydrogen can significantly reduce aviation emissions with potential benefits seen within five years. While not a large contributor to emissions for the sector, on-airport applications represent a straightforward and near-term opportunity to introduce clean hydrogen.

Toyota REXH2 fuel cell module successfully tested on boat over more than 7,000 nautical miles, including trans-Atlantic crossings

Green Car Congress

It has been succesfully tested in real open sea conditions aboard the Energy Observer boat for over more than 7,000 nautical miles including trans-Atlantic crossings. The hydrogen-electric hybrid technology in the REXH2 makes silent maritime and river mobility without emissions of CO 2 or fine particles possible.
