Our Sustainable Approach and Defining Materiality

Our Sustainability Policy establishes a clear set of principles focused on creating lasting benefits socially, economically and environmentally.

It reflects our maturity and aligns with the sustainability focus and outcomes identified in Keeping WA Moving. We developed the policy in consultation with our portfolio partners and industry stakeholders, and it is underpinned by six key aspects:

1. sustainable transport

2. climate change

3. environmental footprint

4. behaviour

5. governance and performance

6. funding and financial matters

These key aspects help us translate and define our sustainability priorities and this flows through to the actions we take to deliver our road network. Corporate Executive receives quarterly sustainability reports to ensure we stay on track and as a check that our policy is delivering value for all Western Australians. Further information on our approach to sustainability, including our policy is on our website.

Defining Materiality

We ensure the relevance and validity of all areas of our business and stakeholder relations through a biennial desktop materiality review and internal stakeholder prioritisation workshops. These results are reported to Corporate Executive.

The review is conducted using a five-step process, informed by the Global Reporting Initiative (GRI) tests for materiality:

  • Step 1 - Analyse the inputs
  • Step 2 - Identify and interview stakeholders S
  • tep 3 - Ask stakeholders to score issues
  • Step 4 - Produce materiality matrix
  • Step 5 - Sense check

The analysis stage draws from our corporate and legislative commitments, key risks, corporate stakeholder engagement processes, media and Ministerial topics and our peers’ reporting practices.

The Matrix shows the results of our five-step materiality process, indicating what is important to our community and stakeholders. For a list of our stakeholders, please see our Additional Environmental and Sustainability Disclosures.

Road Safety

Western Australia’s road death statistic, 6.2 road deaths per 100,000 population, is the poorest of the mainland states – about 33 per cent above the national average. We believe no one should die or be seriously injured on our state’s road network, and we will manage the network for all road users to minimise the likelihood of road trauma.

Congestion and Freight Productivity

It is one of our core objectives to reduce the impacts on our community and economy from congestion on the road network and to provide more efficient access for our freight customers.

Indigenous Heritage and Native Title

We acknowledge the traditional custodians of Western Australia’s lands and aim to protect Aboriginal cultural values wherever possible. We recognise that there is an unacceptable level of disadvantage in living standards, life expectancy, education, health and employment experienced by Aboriginal peoples. We are committed to making a change in our industry and progressing reconciliation.

Local Communities

Our works and operations impact communities that live and work within close proximity. Acquisition of property, construction noise and business continuity are examples of issues that need to be carefully managed, require stakeholder engagement and impact our role as good neighbours.

Procurement Practices

We rely on our supply chain to deliver tasks critical to our overall success. We engage with a large number of suppliers of varying characteristics. In 2019-20 we engaged directly with more than 4,900 suppliers and made in the order of $1.753 billion in payments. We are aware that our terms of payment can impact the cash flow and solvency of various businesses and seek to minimise those impacts. We also leverage our relationship with our suppliers to deliver priority government policy which includes training, indigenous engagement and supporting local business.
