Austroads: Transport Research and Trends

The Austroads 2025 Environment and Sustainability Initiatives Stocktake examines how member agencies are developing and embedding sustainable practices across their organisations. The Stocktake included reviews of environment and sustainability strategies, policies, and practices related to transport assets, systems, and services, focusing on three key themes: overarching sustainability, biodiversity, and heritage.

Building on the 2023 and 2024 Stocktakes, the 2025 analysis offers deeper insights into the progress member organisations are making in integrating sustainability into their operations. Data was collected through a comprehensive survey and validated through focus group sessions. Agencies also completed a maturity self-assessment to reflect on their sustainability integration journey, helping inform the development of case studies showcasing best practice across Australia and New Zealand. Maturity indicators were created for each theme to support organisations in evaluating their current position and identifying opportunities for improvement.

The Stocktake also includes an international scan, reviewing policies and strategies from global counterparts, along with a detailed assessment of the policy, regulatory, and procedural landscape in Australia and New Zealand. This provides a clearer understanding of the complex environment influencing agencies’ ability to shape and implement sustainable outcomes.

During the webinar, we share the key findings from the 2025 Stocktake, highlight major trends and challenges, and explore the initiatives member organisations are undertaking to advance sustainability across the transport sector.
