Clean Energy Fuels to distribute biomethane vehicle fuel to fleets and public stations

Green Car Congress

According to California Air Resource Board (ARB) estimates, Redeem sourced from landfill gas can enable up to a 90% reduction in carbon emissions when displacing diesel or gasoline. The look-up tables for ARB’s Low Carbon Fuel Standard have a range of carbon intensity values (gCO 2 e/MJ) for bio-methane pathways ranging from 11.26

Researchers suggest subsidies and policies targeting plug-ins with small battery packs would produce more benefits at lower cost

Green Car Congress

Larger battery packs enable vehicles to displace more gasoline, so at first glance one might think that subsidizing larger battery packs is better for the environment and for oil security. They found thousands of dollars of damages per vehicle (gasoline or electric) paid by the overall population rather than only by the emitters.

Texas study finds PHEV use could increase ozone at night, decrease ozone during the day

Green Car Congress

The team modeled the air quality impacts of replacing approximately 20% of the gasoline-powered light duty vehicle miles traveled (VMT) with electric VMT by the year 2018 for four major cities in Texas: Dallas/Ft Worth, Houston, Austin, and San Antonio. The results are less clear in Dallas and Houston.
