Pioneering Fossil Fuel Free Construction at One Sydney Harbour Construction is responsible for 23 per cent of greenhouse gas emissions globally, with roughly 5.5 per cent of those emissions caused by powering construction machinery and equipment, largely from mineral diesel. But achieving fully electric, fossil fuel free construction sites is no small feat. That’s why Lendlease partnered with the University of Queensland (UQ) to research the pathway to get there. UQ’s study investigated how quickly the construction industry can decarbonise, using different low and zero carbon construction solutions to substitute mineral diesel. The paper, ‘Planning a Transition to Low and Zero Emission Construction Machinery’1, projected that there is no current pathway to achieving zero emissions construction by 2040 unless we see deep acceleration in the provision of electric construction machinery and equipment. The research highlighted the critical role of renewable diesel as a transition fuel for the construction industry in the short-medium term. With our sights set on reaching Absolute Zero Carbon (Scope 1, 2 & 3 ) within the defined Lendlease boundary and without the use of offsets in that timeframe, we translated these findings into a clear action plan for the industry in a companion report, ‘Stepping Up the Pace: Fossil Fuel Free Construction.’ We’ve begun transitioning towards fossil fuel free construction sites, working closely with our partners and supply chain. At One Sydney Harbour’s Watermans Residences (R3), we substituted diesel machinery and equipment for electric alternatives across all construction activities where options are available. This included a concrete pump, two tower cranes, two hoists, elevated work platforms and a formwork hoist. Altogether, this means that from April 2023 onwards, up to 94 per cent per cent of the monthly energy required to carry out construction work was met using electric machinery and equipment. Electricity powered by renewable sources was used to power the machinery and equipment, meaning it releases zero carbon emissions in operations. Like many decarbonisation challenges, fossil fuel free construction can only be achieved through collective action and systemic change. It’s hoped that by sharing our research, knowledge and lessons learnt along the way, we will inspire others to come with us on the journey. Carbon Neutral Construction In line with Lendlease’s commitment to Net Zero Scopes 1 & 2 by 2025, One Sydney Harbour is also offsetting Lendleases residual emissions generated through all the plant, equipment and machinery used for construction of the project. One Sydney Harbour is certified as carbon neutral for construction services by Climate Active.
