Downer EDI Ltd. has announced its commitment to supporting rail decarbonisation in Australia. The company is integrating emissions reduction strategies into the design, construction, and operation of rail fleets and depots, starting with the High Capacity Metro Trains $(HCMT)$ project in Victoria. As part of the Evolution Rail consortium, Downer has delivered 70 modern trains under a $2.4 billion project. The HCMT initiative has also served as a platform for monitoring and modeling greenhouse gas emissions, informing sustainability practices across Downer's operations. The company has pledged to achieve net zero Scope 1 and 2 greenhouse gas emissions by 2050, a target incorporated into its strategic planning. Downer is extending the learnings from the HCMT project to other projects, including the Queensland Train Manufacturing Program, to further embed sustainability across its portfolio.
