Climate change and sustainability

Today’s investment decisions must identify and balance environmental, social and economic outcomes to ensure infrastructure is sustainable and equitable for future generations. Infrastructure decisions should seek to avoid and mitigate any negative impacts and align to a net zero emissions future.

With around 70% of Australia’s emissions associated with infrastructure-based projects, infrastructure has a very large role to play in meeting the net zero emissions by 2050 target.

Essential infrastructure in sectors such as housing, transport, energy and water is potentially at risk from sea-level rise, coastal inundation, intensifying weather events and bushfires. 

Strategic justification

Infrastructure has the potential to decrease impacts on the environment as well as introduce new pressures on it. Assets that accelerate progress towards net zero greenhouse gas emissions, renewable energy and the sustainable management of water resources, should be prioritised, recognising the crucial threat that climate change poses not just to the natural environment but also to wellbeing and the economy. This includes minimising the impacts of infrastructure on the environment, such as the generation of waste, habitat loss, pollution and the loss of amenity and cultural heritage. Further, planning for new infrastructure should recognise opportunities to enhance the delivery of these environmental and social outcomes.
