Transurban FY18 Sustainability Report

FY18 Sustainability Report Transurban 29

Energy and climate change

Energy performance


Managing our energy needs, and managing our consumption of resources, goods and services, are key to our success in creating operational efficiencies and reducing our greenhouse gas (GHG) emissions and climate change impacts. We have set two key targets to support our long-term goal of carbon neutrality, and to reduce risk and drive innovation. Energy management Transurban’s energy needs include fuel for operations and maintenance activities, and electricity for lighting, tunnel ventilation and offices. In FY18, our electricity use continued to decrease year-on-year while the extent of our operations increased. However, this energy reduction was offset by a significant increase in fuel usage. Reported fuel usage across our North American assets increased significantly as a result of improved contractor reporting processes and expanded operations. Our overall energy use increased in FY18 and is currently tracking above our long term 10 per cent reduction target. Several significant energy-reduction projects were initiated in FY18 including: a Clem7 ventilation trial; Lane Cove Tunnel ventilation study; and Cross City Tunnel and CityLink ventilation-optimisation studies. These projects, and follow-on initiatives, are expected to deliver significant energy reductions once fully implemented during the next two years and bring us back in line with our target.

FY18 key figures: • 568,370 GJ energy consumption • 123,545 tCO 2 e Scope 1 and 2 GHG emissions • committed to a 52 per cent reduction in Scope 1 and 2 GHG emissions by 2030 • 140 kW of installed renewable electricity generation capacity • Scope 3 GHG emissions mapped across full supply chain • Clem7 ventilation trials: six months of successful implementation, saving 300 GJ of energy and avoiding 236 tCO 2 e.
