A "Greenroad" is a transportation project that is designed and constructed to a level of sustainability substantially higher than current common practice.
The Greenroads Rating System is a third-party, points-based system available to certify the performance of sustainable transportation infrastructure projects. The system provides metrics to measure the effect of design and construction practices, which can be implemented on a project to earn points toward one of four awards, called "Ratings." Learn more.
The Greenroads Rating System is the only third-party system specifically designed to recognize high performance in transportation infrastructure projects — all other programs are self-assessment tools or try to compare different types of infrastructure projects to each other. Plus, the Greenroads certification process is independent, transparent, way easier to use, and it's fun to be a part of it.
Greenroads provides explicit documentation instructions and tangible achievements, as well as quantifiable sustainability benefits supported by rigorous empirical evidence.
In short, it's the real deal. Our goal is to share information and coach teams to build a more sustainable projects with rigorous assessment tools to clearly prove you've met real and documented sustainability goals. This is no self-assessment or pat on the back. City leaders, highway agencies, and funders love Greenroads because we help them transform the way their communities experience infrastructure, one mile at a time.
A Greenroad actually often costs less because the materials, technologies and systems used make it more durable, so it requires less maintenance. New best practices save money, most notably during construction.
Several projects have documented cost savings for their taxpayers, including both reduced initial costs and lifetime operations and maintenance costs because what they learned from participation in the project rating program. These lessons learned are transferrable to future projects and can help agencies build sustainably with economies of scale.
The Greenroads Rating System is a collection of sustainable roadway design and construction best practices that encompass water, environment, access, community impact, construction practices and materials. Each practice is assigned a point value according to its contribution to roadway sustainability.
Project teams voluntarily elect which credits to pursue based on the scope of their project and sustainability goals. The team prepares submittals for each credit throughout project development and delivery, which are reviewed by Greenroads staff at scheduled submittal dates. Greenroads reviews the documents and evaluates the project's performance of each credit, determining how many points are earned.
At a minimum, there are 12 "Project Requirements” that must be completed for a roadway to be considered a Greenroad. There are also 45 "Core Credits" that a project can choose to pursue in 5 different categories: Enviroment & Water, Construction Activities, Materials & Design, Utilities & Controls and Access & Livability. There are 4 additional credits that recognize innovation in teaming, strategy, development and delivery. Each voluntary credit is worth between 1 and 5 points based on research on lifecycle impacts associated with satisfactory performance of that practice.
Greenroads assigns a project score based on the number of points amassed by meeting the requirements and achieving credits. This score translates to one of four certification levels: Bronze, Silver, Gold and Evergreen.
It is applicable to all types and sizes of transportation projects, including new, rehabilitation, reconstruction, preservation, overlay and bridge projects and even rails and trails. (We've tested it, it's true.) For anything not on this list, we suggest you try a Pilot Project. If you're not sure, submit a screening application and we'll check it out for you.
In 2019, we are currently actively seeking pilot projects for a co-branded program called Greenrails.
Yes, we can score it but no, it cannot be certified until it is constructed. We have a few different ways to score a project in design. Please refer to the “Rate My Project” section on the Greenroads website here.
The Greenroads Rating System benefits roadway owners, transportation planners, designers, contractors, developers, policy makers, materials suppliers and students.
With existing knowledge, smarter design and available technologies, roads can be sustainable, connective and durable – starting today. Greenroads seeks to go beyond conventional practice and regulations to optimize various elements that contribute to roadway sustainability, including:
A Greenroads Certified Project provides many benefits including:
Roads and other surface transportation infrastructure only covers one-percent of the U.S. but the ecological effects are widespread. Environmental problems include pollution, noise, advancement of sprawl and degradation of natural habitat. Roads and rails create barriers to interaction in communities and divide ecosystems that need to be connected to survive. Here are some statistics:
And, 90% of new transportation development is happening outside developed countries around the world. 90%!
Road design standards, construction methods and measurements have remained relatively stagnant for the last five decades and are out of date in the modern world. Fifty years ago, roads were designed mainly for cars, with the goal focused simply on getting from one place to the other. Road construction was driven by the belief that they should be built as cheaply as possible, which often led to negative community impacts and environmental consequences.
Even if no new roads are built from this point forward, existing roads need to be fixed, and the system for designing and constructing transportation infrastructure needs to be updated. Just as buildings are being designed to be more resource-efficient, healthier and long-lasting, there are methods to design and build roadways to be sustainable, durable, and benefit the surrounding community and greater ecosystem. The Greenroads Rating System offers metrics to change practice in a sustainable way, and provides resources for effective ways to evaluate and incorporate the latest technologies and systems.
Greenroads was founded as a company in summer 2010 in Washington state by Jeralee Anderson and Steve Muench.

Yes! We fully respect and honor all requests for confidentiality. If your project is confidential (i.e. in a competitive bid), let us know when you submit your free screening application, and we will omit it from the public listing in the Project Directory. Note that our staff operates fully independently of your potential competitors and we do not share your information with others, or the owners.
If you are linked to a Project Team, you can access your Project Workspace from your personal Portfolio on your My Profile Page when you are logged in.
There are at least four ways to provide comments to Greenroads.
We try to return answers promptly and answer in the same level of formality that the comment was received.
We use an offsite learning management system located here: http://learn.greenroads.org. Note that there is no "www." You will need to use your Greenroads login credentials to access anything there.
Your STP Certificates are uploaded to your My Profile Page and can be downloaded once you are logged in. We grade exams and prepare certificates approximately once a month, starting the first week of the month. Depending on the size of the examinee pool for that month, it can take a bit of time for us to create and upload them.
The Greenroads Manual v1.5 was published in 2011. It still serves as perfectly good, free guidance on best practices for project teams. However all of the credit goals, requirements and documentation elements are now out of use in actual Certification. There are also several credits which have been dismissed from the system altogether. You can find it under Archived Resources.
Yes. There is precedence at all levels of government for use of many types of funds, including federal/national, state/provincial, and city/county/local. Greenroads is typically considered to be similar to a quality assurance expense by most owner agencies.
None that we are aware of specifically. If you find one, let us know. Many grants do have sustainability criteria as part of their award conditions, and Greenroads can help satisfy many, if not more of these criteria (including TIGER, TIGGER, MAP-21 criteria projects).
Staff and board members of Greenroads are actually some of the original authors for the Federal Highway Administration's free self-assessment tool (like our free checklist) called INVEST. They are fundamentally different tools that both fit the transportation discipline, and if you look closely at the credits in Greenroads and the criteria in INVEST, they are extremely similar, especially for project development. Hmmm....no surprise there. You will probably find it looks more like Greenroads V1.5 than Greenroads V2 though many of the original ideas from V1.5 are retained in V2.
INVEST is a great tool to use to prepare a project early on for successful Greenroads Certification, especially in early highway planning and development. Greenroads also offers 1 free INVEST rating for any Greenroads Registered Project with U.S. federal funds, by request, if for some reason you need it.
