Transitioning to Low-Carbon Trucks

Tuesday, June 16th, 2015
Figure ES-1. Required ZEV sales share to hit 80-in-50 target with no biofuels v. scenario with 60% biofuels blends by2050

NATIONAL CENTER FOR SUSTAINABLE TRANSPORTATION
UC DAVIS INSTITUTE OF TRANSPORTATION STUDIES
The United States and California have both made commitments to an 80% reduction in energy-related greenhouse gases (GHGs) from 1990 levels by 2050 in order to help stabilize atmospheric concentrations of greenhouse gases. These commitments do not specifically target transportation or an individual transport mode.

This white paper reviews previous studies and provides a new investigation into the feasibility of achieving an 80% reduction in CO2-equivalent (CO2e) GHG emissions in the United States and California from trucks in the 2050 time frame (“80-in-50”). We assess the technological and economic potential of achieving deep market penetrations of low-carbon vehicles and fuels, including vehicles operating on electricity, hydrogen, and biofuels.

Tapping Iowa’s Wind Resources to Reduce CO2 Emissions

Thursday, May 7th, 2015
Of particular interest is the corollation especially observable in the 2010 – 2012 years, between the CO2

IOWA WIND ENERGY ASSOCIATION
In a conservative scenario it is estimated that Iowa wind could easily contribute a reduction of 15 million metric tons of carbon dioxide annually to the region outside of Iowa, and in a more optimistic but still moderate scenario Iowa’s contribution could easily be over 36 million metric tons annually.

Boston: Methane Emissions from Natural Gas Infrastructure

Thursday, January 29th, 2015
methane fig1

PROCEEDINGS OF THE NATIONAL ACADEMY OF SCIENCES OF THE UNITED STATES OF AMERICA (PNAS)
Most recent analyses of the environmental impact of natural gas have focused on production, with very sparse information on emissions from distribution and end use. This study quantifies the full seasonal cycle of methane emissions and the fractional contribution of natural gas for the urbanized region centered on Boston. Emissions from natural gas are found to be two to three times larger than predicted by existing inventory methodologies and industry reports. Our findings suggest that natural-gas–consuming regions may be larger sources of methane to the atmosphere than is currently estimated and represent areas of significant resource loss.

Guest on The Infra Blog: Alison Taylor, Vice President, Sustainability – Americas, Siemens Corporation

Wednesday, January 14th, 2015
Alison Taylor, Siemens Corporation

Alison Taylor is Vice President, Sustainability-Americas at Siemens Corporation. In this position, she is responsible for driving the sustainability program for the Americas and acting as a resource for sustainability initiatives across Siemens’ business sectors.

“Rather than fixing a short-term problem, or addressing a crisis, or repairing a problem that may have occurred, let’s say, after a major storm or mother-nature event, sustainability is about a more long-term view. Will we be able to count on that infrastructure many years in the future? How will it serve the public? How will it serve the needs of the city?”

More Wind, Less Warming

Wednesday, December 17th, 2014
Figure ES-1. A Path to 30 Percent Wind Electricity

ENVIRONMENT TEXAS
American wind power is already significantly reducing global warming pollution. In 2013 alone, wind power averted 132 million metric tons of carbon dioxide emissions – as much as would be produced by 34 typical coal-fired power plants. But with the United States and the world needing to move toward a future of 100 percent clean energy in order to prevent the worst impacts of global warming, America must do much more.

Dear Friends,

 

It is encouraging to finally see clear signs of federal action to support a comprehensive US infrastructure investment plan.

 

Now more than ever, our advocacy is needed to keep stakeholders informed and connected, and to hold politicians to their promises to finally fix our nation’s ailing infrastructure.

 

We have already engaged nearly 280,000 users, and hoping to add many more as interest continues to grow.

 

We require your support in order to rise to this occasion, to make the most of this opportunity. Please consider making a tax-deductible donation to InfrastructureUSA.org.
