There is a relatively new infrastructure sustainability rating tool that has been released by the Institute for Sustainable Infrastructure (ISI) called Envision. The rating system was released in January, 2012 and started accepting ISI certification applications in September, 2012. Unlike most rating systems that are specific to buildings and transportation systems, the Envision Sustainability Rating Program has been developed to integrate sustainability into all types of infrastructure projects such as airports, pipelines, drainage projects, land developments, mining operations, etc. (except buildings). The Envision Rating Program has a unique rating system that is a holistic-systems-based approach that rates and scores projects in terms of “levels of achievement” toward obtaining resource enhancement and restoration (highest levels), as oppose to the simplistic yes/no rating system checklist used by other sustainability rating systems. Read More

On July 6, 2012, President Obama signed into law P.L. 112-141, the Moving Ahead for Progress in the 21st Century Act (MAP-21). Funding surface transportation programs at over $105 billion for fiscal years (FY) 2013 and 2014, MAP-21 is the first long-term highway authorization enacted since 2005.  Read More

One of the challenges in developing a sustainability program is not the identification of sustainable actions or rating system criteria. There is a lot of literature and information developed by Departments of Transportation (DOTs), consultants and institutes on sustainable actions and performance measures that can be used as sustainability tools. The challenge lies in how sustainable actions can actually be implemented within a state or municipal DOT organization.  Read More

Global warming comes with a big price tag for every country in the world. The 80 percent reduction in U.S. emissions needed to stop climate change may not come cheaply, but the cost of failing to act will be much greater. New research shows that if present trends continue, the total cost of global warming will be as high as 3.6 percent of gross domestic product (GDP). Four global warming impacts alone -- hurricane damage, real estate losses, energy costs, and water costs -- will come with a price tag of 1.8 percent of U.S. GDP, or almost $1.9 trillion annually (in today's dollars) by 2100 (1).  Read More

Is developing a transportation sustainability program and establishing project level best practices (criteria) cost effective?

This question is one of the reasons why sustainability programs have not been well adopted and endorsed by many transportation management, engineering and maintenance representatives at the federal, state and local level and transportation lending institutions. Sustainability-cost effectiveness is an area that has not been well articulated to upper management and key decision makers.
The bottom-line is that many of the transportation decision makers do not care or see the value of sustainable elements, such as environmental habitat enhancement, unless there is a cost savings or perceived value. It is a challenge to put a cost toward increasing lynx mobility via sub-grade animal crossings or avoidance of species habitat. Read More

Why is it that the general public who use the federal and state highway transportation system are unwilling to invest in maintaining their current infrastructure system? Why is there so little political leadership to address this critical issue?  Read More

One of the many challenges facing federal state and local transportation agencies developing sustainable "green highway systems" is the lack of research and the subsequent adoption as inclusions in design/contractor specifications. If new sustainability based actions are to be realized on highways, new approaches and technologies need to be tested, proven and adopted by DOTs. A menu of sustainability based specifications needs to be provided to transportation designers, contractors and operation/maintenance professionals to improve implementation timing.  Read More

Many state, county and municipal departments of transportation (DOTs) are spending significant amounts of financial resources on stormwater management; especially for the Municipal Separate Stormwater Sewer System (MS4) Permit requirements for post-construction best management practices. Is this really an environmentally and financially sound approach to protect water quality? Read More

Summary of the 2011 Transportation Research Board (TRB) Waste Management & Resource Efficiency Committee Workshop; “Sustainability & Liability in Transportation”

The Sustainability & Liability in Transportation Workshop was held in Portland, Oregon (hosted by the Oregon Department of Transportation) from July 25-27, 2011. There were a total of 37 presentations given by national and international transportation professionals during the first two days of the workshop. The third day involved a boat tour of the Portland Harbor Superfund Site. The workshop was well attended by representatives from state departments of transportation, the Federal Highway Administration and transportation consulting firms. Read More

Sustainability based rating systems have become quite numerous over the past few years.  It is estimated that there are over 200 individual rating systems for civil engineering projects. I thought it would be informative to share a summary of some rating systems that are or are currently being planned to be used by transportation agencies. It is hard to determine if these rating systems will eventually be consolidated into just a few credible rating systems or programs. Many programs that have been developed are specific to an organization’s operations, environmental needs, local context and sustainability philosophy.  Read More
