ICCT LCA study finds only battery and hydrogen fuel-cell EVs have potential to be very low-GHG passenger vehicle pathways

Green Car Congress

In addition to its regional and temporal scope, this study is distinct from earlier LCA literature in four key aspects: This study considers the lifetime average carbon intensity of the fuel and electricity mixes, including biofuels and biogas. This results in significantly lower battery production emissions than in earlier studies.

UMTRI study finds US diesel vehicles generally have lower total cost of ownership than gasoline vehicles

Green Car Congress

TCO for selected gas and diesel vehicles over a 3 year timeframe. Diesel vehicles generally saved owners between $2,000 to $6,000 in total ownership costs during a three to five year period when compared to similar gasoline vehicles, according to data compiled by the University of Michigan Transportation Research Institute (UMTRI).

JATO: new car CO2 emissions rise for the first time in a decade in Europe; diesel down, gasoline up, SUVs up

Green Car Congress

Covering 23 European markets, the study found that average CO 2 emissions increased by 0.3 g/km in 2017—far higher than the average CO 2 emissions of diesel and gasoline vehicles across all segments. g/km in 2017—far higher than the average CO 2 emissions of diesel and gasoline vehicles across all segments.

Emissions Analytics study shows GPFs make a big difference

Green Car Congress

A recent study by leading UK-based independent emissions testing company Emissions Analytics tested four apparently similar pairs of gasoline-fueled vehicles between the US (without gasoline particulate filters (GPFs)) and Europe (with GPFs). The US vehicles were tested in Michigan, and the European vehicles in the UK.
