Environmental leadership

Our major infrastructure projects remain the most resource intensive-area of our business—so they are also our biggest opportunity for reducing our environmental impacts. Our design and construction projects also serve as springboards for innovation, enabling the development of more sustainable materials and delivery methods. Engaging our suppliers We are engaging with our suppliers on GHG reduction and climate risk management through CDP Supply Chain reporting. Last year we engaged with our top 50 suppliers (by spend) to support them in establishing CDP reporting processes. This group represents 66% of our emissions from purchased goods and services so getting suppliers on board and having oversight of their progress is important to our success. So far: • 35% of disclosing suppliers’ total energy consumption is sourced from renewable energy • 25 of our top 50 suppliers reported having active GHG reduction targets in place. Decarbonising construction Rethinking the way we plan, design, construct and operate assets to reduce their whole-of-life impact is fundamental to achieving our Scope 3 GHG emission reduction targets for our supply chain and projects (see page 38). This means

continuing to work with our contractors and suppliers on low-carbon and circular- materials strategies while also reducing direct fuel consumption and waste and increasing renewable energy use. Project specifications and materials changes we’ve implemented with our partners to date have reduced GHG emissions by about 644,000 tCO 2 e across nine projects. 1 The production of many road construction materials (including concrete, steel and asphalt) currently relies heavily on fossil fuels. For example, production of cement— an ingredient used in concrete—accounts for about 8% of all global GHG emissions. 2 To meet our emission reduction targets, we are working with our contractors, government and industry partners to increase the use of low-carbon concrete and other materials. Out of 271,000 m 3 concrete poured on the M4–M5 Link project, we replaced 32% of cement with fly ash (a power-generation waste material) and other supplementary cementitous materials (SCM). This reduced emissions associated with cement production, diverted 35,000 tonnes of waste from landfill and far exceeded the project’s 5% SCM target. One of the key areas of focus in our journey to net zero is addressing indirect (Scope 3) GHG emissions from materials. In FY22, we continued our role as a founding partner with the Materials Embodied Carbon Leaders Alliance (MECLA). More than 150 industry representatives and government agencies participate in MECLA, which aims to drive reductions in embodied carbon in the building and construction industry. MECLA also aims to achieve a one million tonne carbon emission reduction by 2030. We participate in two of the organisation’s eight working groups, focused on identifying: • ways to create demand for low/zero embodied carbon materials • opportunities to reduce emissions associated with cement and concrete.

M4–M5 Link project highlights:

100% usable spoil reused/ recycled (target 80%)

97% construction and demolition waste reused/recycled (target 80%)

63% of 665,137 kl

water used during construction was reused, recycled

or reclaimed (target 15%)

32% cement replacement material used in concrete (target 5%)

21% forecasted
