Greenroads
The Transport Agency is using Greenroads® as a tool to assess the sustainability performance of high-value state highway improvement projects. Greenroads assessment and certification applies to the detailed design and construction stage of a project.
A recommendation to certify a project to Greenroads will be made at the detailed business case stage for state highway improvement projects with an estimated capital value over $15 million that will be delivered via design and construction, alliance or public-private-partnership delivery models.
If a selected project is consented, the Transport Agency will determine the appropriate Greenroads certification level and include that in the tender documents for detailed design and construction. During the procurement phase, project teams tendering for projects subject to Greenroads will be required to provide evidence that they can achieve the desired certification level.
Successful tenderers will be contractually required to seek Greenroads assessment during the detailed design and construction stage and certification by project opening.
Why Greenroads?
The Transport Agency delivers environmental and social outcomes as part of the design, construction and operation of state highway projects. These outcomes are delivered as part of the Agency’s commitment to environmental and social responsibility, and to address opportunities or risks raised during the public engagement and approvals processes.
By using Greenroads, the Transport Agency builds its understanding of how state highway environmental, social and economic outcomes rate against an international framework and can communicate these outcomes to interested parties. Greenroads allows project teams to be recognised for the outcomes they achieve. The Transport Agency is using Greenroads to understand how committed outcomes rate on an international scale, not to seek additional outcomes.
What is Greenroads?
Greenroads is an international sustainability rating system for roadway design and construction, which is applicable to any road construction project.
It provides a collection of sustainability best practices and awards points for achievement of credits. Four certification levels (ratings) are available depending upon the total score - bronze, silver, gold or evergreen.
A Greenroads rating is sought by the project team and certified by an independent third party, providing a benchmark against other roading projects in New Zealand and internationally.
