Respond to climate change

Transport is working to mitigate, adapt and respond to the climate crisis by reducing our greenhouse gas emissions and building climate resilience across our network of existing and future infrastructure projects.

Our goals

Net zero emissions by 2050

Consider climate change risks in all decisions

Why it's important

Climate change is the global challenge of our time.

Climate risks – such as extreme temperatures, a higher likelihood of drought, sea-level rise, extreme rainfall and bushfires – are a threat to our infrastructure assets across the state and the communities we serve.

Current greenhouse gas (GHG) emissions

We’re committed to rapidly reducing our greenhouse gas emissions, transitioning to low-carbon options and building climate resilience across our network.

Pie charts depicting the distribution of contributions to Green House Gas (GHG) emissions throughout Transport's network.

The wider transport sector represents about 20 per cent of NSW greenhouse gas emissions, with our services contributing around six per cent of the total transport sector emissions. Rail and buses total about 90 per cent of scope 1 (direct) and scope 2 (indirect) emissions from our services. Our ferries, depots, offices, street lights and vehicle fleet make up the remaining ten per cent of direct emissions.

Our challenges

The transport sector uses more energy than any other in the NSW economy. It is second only to the energy industry in greenhouse gas emissions but is predicted to be the largest source of emissions by 2030.

Encouraging emissions reductions outside of those we directly produce from our activities and operations is a crucial challenge. Road transport emission are currently the dominant source of emissions, with increases driven by heavy vehicles, aviation and shipping. Electrification can significantly reduce emissions from passenger and light commercial vehicles. However, there is no market-ready technology to significantly decarbonise heavy vehicles.

Our network is exposed to multiple climate change risks. We need to implement risk assessment processes consistently, identify which risks are the most severe and find the best value approach to mitigating risks.

Taking action

We’re transforming the Transport sector to net-zero emissions by 2050 through our Future Energy Strategy and Action Plan by:

Moving to net-zero electricity for the electric rail network by 2025

Implementing energy efficiency opportunities

Transitioning to zero emission buses which provide cleaner air quality, lower noise pollution and lower operating costs

Setting a challenge of transitioning the entire NSW fleet of 8000+ buses to zero emission vehicles with the Zero Emission Bus Transition Strategy


We conduct risk assessments using the latest data that consider the likelihood, consequence and severity of impacts to ensure our assets are climate resilient from planning to design, construction and operations.

We look for opportunities to strengthen climate resilience of our existing operational assets and implementing mitigation and adaptation measures through maintenance and upgrade programs.
