Toxic Trash Exposed: Coal Ash in Michigan

Friday, November 8th, 2013

CLEAN WATER FUND
Water defines, and is central, to Michigan’s economy. Major tourism, agriculture, and fishing industries depend on the health of rivers, lakes, and streams. The Great Lakes contain over 20% of the world’s usable fresh surface water. Unfortunately unmitigated coal ash pollution is a major threat to the health of the state’s water and economy.

Fracking by the Numbers

Fracking by the Numbers

ENVIRONMENT AMERICA
Our analysis shows that damage from fracking is widespread and occurs on a scale unimagined just a few years ago. Moreover, three factors suggest that the total damage from fracking is far worse than we have tabulated here. Severe limitations in available data constrain our ability to see the full extent of the damage. Second, there are broad categories of fracking damage—such as the number of water wells contaminated—that would be difficult to ascertain under any circumstances. Finally, there remain major gaps in the scientific community’s understanding of issues such as the long-term consequences of pumping toxic fluids into the ground.

U.S. Domestic Airline Fuel Efficiency Ranking

Wednesday, September 25th, 2013
ICCT Figure ES-1

THE INTERNATIONAL COUNCIL ON CLEAN TRANSPORTATION
The analysis presented here rigorously compares the efficiency of all airlines independent of size, network structure, or type of service, with a methodology that improves upon previous efforts in four fundamental ways. First, it uses airline-reported fuel consumption data, rather than modeled estimates, to account fully for all the ways in which airlines can reduce fuel burn…Second, it develops an efficiency metric that recognizes that airlines burn fuel to provide both mobility…and access, allowing an equitable comparison between airlines. Third, the efficiency metric distinguishes productive from nonproductive miles flown by identifying those airlines that operate particularly circuitous routes. Finally, the study attributes the transport service provided by and fuel consumption of affiliate carriers to mainline carriers in order to enable comprehensive comparisons across carriers’ full business operations.

Guest on The Infra Blog: Rob Gramlich, Senior Vice President, Public Policy, American Wind Energy Association

“If the wind stops blowing in one place it’s most likely blowing somewhere else around that region and therefore across the region, and these are regional electricity markets that we have in the country. Across the region wind itself is not variable…if you spread it out with transmission across such a wide region.”

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.
