Decarbonising operations To support our Scope 3 targets, we are increasingly including contractual supplier requirements for the provision of low- carbon products and services, for example: switching to renewable energy and/or setting science-based GHG emission reduction targets. We also encourage suppliers under existing contracts to adopt similar low- carbon strategies. Currently, diesel Truck Mounted Attenuator (TMA) trucks are responsible for at least 30% of Scope 1 (fuel) emissions from Ventia’s operations on our NSW roads, due to idling during traffic management activities. To reduce these GHG emissions, Ventia has ordered an Electric TMA—an Australian first—that is expected to be operating on Sydney’s M2 Motorway in mid 2023. As part of a pavement trial on the M2 Motorway in NSW, recycled tyres were applied as crumb rubber asphalt. In road construction, crumb rubber is predominantly truck and car tyres, which is combined with aggregates in the dry manufacturing process before adding bitumen to produce crumb rubber asphalt. The trial content made up around 2% of the total asphalt, and it is estimated that approximately 563 equivalent passenger car tyres were recycled.
The Infrastructure Sustainability Council (ISC) manages and advocates the use of its Infrastructure Sustainability (IS) rating scheme to improve sustainability outcomes over the lifecycle of infrastructure assets in Australia and New Zealand. Version 1.2 of their Design and As Built rating tool has three rating levels—‘Commended’ (25–49 points), ‘Excellent’ (50–74 points) and ‘Leading’ (>75 points). We have committed to achieving at least Excellent IS ratings for the design and construction phases of all our major Australian projects. We set targets and monitor project management, procurement, environmental impact, community wellbeing, stakeholder engagement, and innovation performance throughout delivery to ensure IS ratings are met. We are continuing to work on achieving our first operations IS rating, for the M2 in Sydney. In North America, Transurban’s major project procurement process invites contractors and service providers to include sustainable development principles in proposals and solutions. From planning and preliminary engineering, design, construction and operation, all suppliers are required to provide solutions that mitigate risks and generate social and environmental benefits for both the communities where we operate and globally. Achieving project sustainability ratings
For example, for major projects, contractors are required to achieve an Envision rating from the Institute for Sustainable Infrastructure—the North American equivalent to the ISC. Under Envision, five levels of achievement are possible—Verified, Bronze, Silver, Gold and Platinum. To ensure all new major projects contribute to our emission reduction targets, we are enhancing our project specifications to help reduce direct fuel consumption and increase renewable energy and low-carbon material use. We are working to achieve an Envision Silver rating (rating tool Version 3) for the Fredericksburg Extension project’s design and construction, and have set an Envision Silver rating requirement for the 495 Express Lanes Northern Extension project. Our proposal for the Maryland Express Lanes Project—Phase 1 aims to achieve the Envision Platinum, including via significant above-regulation community and environmental programs and initiatives.
To support our Scope 3 targets, we are increasingly including requirements for the provision of low- carbon products and services in our contracts.
