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

Green Car Congress

Major ridesourcing companies Uber and Lyft have promised all-electric fleets by 2030 in an effort to reduce their carbon footprint. However, few studies have used real-world rideshare trip data in their estimates, or included additional assessments of air pollution and traffic impacts, from the switch.

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

Green Car Congress

On this basis, and of Pareto efficiency, Emissions Analytics argues, until battery-electric vehicles can reach certain performance characteristics, government and industry support should switch immediately from EVs to full hybrids to create maximum welfare. Every air pollutant is more than 90% its limit.

EEA report: EVs are better for climate and air quality

Green Car Congress

Battery electric cars emit less greenhouse gases and air pollutants over their entire life cycle than petrol and diesel cars, according to a European Environment Agency (EEA) report. Emissions are usually higher in the production phase of electric cars, but these are more than offset by lower emissions in the use phase over time.

PSI team develops web tool for consumers to compare environmental impact of passenger cars in detail

Green Car Congress

A recent PSI study led by environmental scientist Christian Bauer found that a battery electric car is already the most environmentally friendly option in Switzerland and many other countries, even when the manufacture of the battery is figured in. When, Where and How can battery-electric vehicles help reduce greenhouse gas emissions? (in

Tsinghua University provincial-level lifecycle study finds fuel-cycle criteria pollutants of EVs in China could be up to 5x those of natural gas vehicles due to China’s coal-dominant power mix

Green Car Congress

In regions where the share of coal-based electricity is relatively low, EVs can achieve substantial GHG reduction, the team reports in a paper in the ACS journal Environmental Science & Technology. China recently launched several EV demonstration programs (e.g., Earlier post.]

Renault makes public its lifecycle study of Fluence ICE vs Fluence EV

Green Car Congress

Renault’s comparison of the carbon footprint of EV and ICE vehicles over production, operation and end of life. The publication gives the opportunity for an “apples-to-apples” comparison between the environmental impacts of the two types of powertrains: same manufacturer, same model, same boundary conditions. Gasoline Fluence 16V.
