Study finds GHG emissions from corn ethanol now 46% lower than gasoline

Green Car Congress

A new study by a team from Environmental Health & Engineering (EH&E) has found that greenhouse gas emissions from corn ethanol are 46% lower than those from gasoline—a decrease in emissions from the estimated 39% done by previous modeling. gCO 2 e/MJ) which is 46% lower than the average carbon intensity for neat gasoline.

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.

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. But the cars and SUVs used in these situations drive more miles each year than a typical personal vehicle, contributing a higher proportion of greenhouse gases to the environment.

Ford poll finds Europeans want freedom of car ownership, but worry about traffic, cost of driving, environment

Green Car Congress

A new Ford Motor Company-sponsored poll of 6,000 people across Europe found that most Europeans remain committed to car ownership, but have growing concerns about traffic congestion, the cost of driving and the environment. 52% use public transport less than once a month or never. 53% say climate change is the world’s biggest problem.

Rice study finds using natural gas for electricity and heating, not transportation, more effective in reducing GHGs

Green Car Congress

The use of compressed natural gas in vehicles yielded the least benefit, essentially matching the emissions of modern gasoline or diesel engines. Three direct substitution studies all showed far more favorable net impacts for replacing coal-fired electricity than for replacing gasoline or diesel vehicles.

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.
