The Greenroads Rating System is an international sustainability rating system specifically relevant and weighted for surface transportation infrastructure projects. Waka Kotahi NZ Transport Agency introduced Greenroads in 2015 to assess the sustainability performance of selected high value state highway improvement projects during design and construction. Greenroads International, an independent non-profit organisation, provides a rigorous review of an entire project through its project planning, design and construction. 

The following state highway projects are currently seeking (or are required to seek) Greenroads certification.

Construction project teams lead the Certification process with intent to earn an as-built Certification award by delivering a project that meets the performance measures stated in the Rating System. Greenroads staff assess the project’s performance against mandatory Project Requirements and a range of sustainability categories covering environmental, social and economic aspects. Additional information can be found on the Greenroads website or by contacting the Technical Services Team at environment@nzta.govt.nz.

Introducing Greenroads has helped Waka Kotahi build an understanding of how state highway environmental, social and economic outcomes rate against an international framework (what ‘good’ looks like) and communicate these outcomes to interested parties. Greenroads allows project teams to be recognised for the outcomes that they achieve.

Who is the owner of Greenroads projects?

Waka Kotahi is the ‘owner’ of Greenroads projects and has oversight of the process. The construction project team lead the certification process on behalf of the ‘owner’.

Payment of Greenroads certification fees

The construction project team is required to pay for certification fees related to the project. Payment is made as per agreed with Greenroads through the payment plan and submittal schedule.

A project team can use the certification fees calculator on the Greenroads website to gain an estimate of how much certification fees will be for budgeting purposes.

What does it cost - resourcing and other considerations?

There will also be costs incurred by the Project for the time and resources it takes to develop and submit the documentation and evidence required by Greenroads and to respond to any outstanding matters. Some additional investigation of options to meet Greenroads credits may be required or desired although it is anticipated that many credits will be achieved as part of good design practice and construction methods. Aligning the project early with Greenroads will help avoid costly rework and reduce the Greenroads implementation costs. Efficiency is greatly improved if someone who understands Greenroads embeds Greenroads requirements into project processes and documentation.
