California meets GHG goals, but transportation progress faces uncertain future

By Robbie Webber As reported in the Los Angeles Times, California has met its target for reducing greenhouse gas emissions below 1990 levels four years early, an impressive feat, and one that comes while the California economy continues to flourish. But the reductions come almost entirely from

Nevada green-lights autonomous trucks

by Bill Holloway Truck platooning, connecting a chain of computer-controlled trucks electronically to follow a human-driven lead vehicle, is still at least 5 years away from being used commercially, but the next step in freight transport automation is already coming over the horizon. Earlier this

New report outlines steps needed to reduce petroleum use and greenhouse gas emissions

By Bill Holloway A new report outlines what would be required to substantially reduce both petroleum usage and greenhouse gas emissions by 2050. It concludes that the goals are ambitious but achievable; however, government incentives, mandates, and research funding will be needed. The goals are

Fuel saving technologies for truck fleets

By Bill Holloway According to a new report from Carbon War Room, the adoption of seven fuel-saving technologies by the U.S. trucking industry could reduce carbon emissions by 624 million tons over the next ten years and repay implementation costs within 18 months through reduced fuel

Mileage-Based User Fee Winners and Losers An Analysis of the Distributional Implications of Taxing Vehicle Miles Traveled, With Projections, 2010–2030 (Rand Corporation, 2012)

This study uses household-level survey data of travel behavior and vehicle ownership to estimate changes in annual household demand for VMT in response to changes in the cost of driving that result from adopting mileage-based user fee (MBUF) alternatives. Equity is a commonly raised public

Ecodriving and Carbon Footprinting: Understanding How Public Education Can Reduce Greenhouse Gas Emissions and Fuel Use (Mineta Transportation Institute, 2012)

Ecodriving is a collection of changes to driving behavior and vehicle maintenance designed to impact fuel consumption and greenhouse gas (GHG) emissions in existing vehicles. Because of its promise to improve fuel economy within the existing fleet, ecodriving has gained increased attention in

As gas tax yields less revenue, renewed focus is placed on a mileage tax

Higher fuel efficiency standards and a weak economy have made the motor-fuel tax—the principal fundraiser for road costs in the US for 80 years—increasingly less viable. As better mileage becomes the norm in the American car industry, consumers will use less fuel, thus decreasing government

How do you get there from here?

Fuel taxes are no longer a good way of funding the transportation system. With increasing fuel efficiency and new fuels powering transportation, the fuel tax as we know it is not sustainable. Two national commissions set up by the U.S. Congress recommended replacing fuel taxes with a

CAFE standard sound off

The new Corporate Average Fuel Economy standard has been released and there is no shortage of opinions on its worth. Here is a roundup of various responses to the Obama administration’s new fuel efficiency standard:   It’s great! An NHTSA press release touts the benefits of saving $1.7

Charged for what you use? Tennessee Commissioner of Transportation Schroer proposing pay-per-mile idea.

The downside of fuel efficiency is that fuel tax revenues decline with increased efficiency, while wear and tear on the roads does not. Tennessee is predicting it will lose tens of millions of dollars over the next 10 years with more and more fuel-efficient cars on the road. As the Williamson
