ESG & Strategic Sustainability
At the heart of sustainability is balancing growth with environmental stewardship and social welfare to deliver longterm value to stakeholders.
ESG (Environmental, Social, and Governance) represents a framework to identify, evaluate and manage non-financial issues relevant to both an organisation and its stakeholders.
– Environmentally it looks at impacts on the planet such as energy and water use, waste discharges and resources needed as well as development of sustainable products and services.
– Socially it drives awareness of, and improvement of workforce inclusivity and wellbeing, human rights and social equity, as well as relationships with local communities and stakeholders throughout the value chain.
– Governance considers the policies, decision-making rules, organisational structure, and systems of practice that guide how an organisation operates transparently and inclusively.
Enabling Resilience
Increasingly, ESG is redefining the value and risk exposure of an organisation. We have the knowledge, skills, and resources to enable your sustainability journey, from ideation to implementation, to create purpose-driven resilient operations that drive:
– Reliability and operational cost reduction

Demolition of Clyde Oil Refinery Including Duck Creek Bridge
AUSTRALIA
GHD’s role on the project was to provide assistance with the development of the demolition methodology, (including drawings) complete structural calculations, including provision for temporary works for pre-weakened structures. GHD completed the structural calculations for the induced collapse of the chimney stacks and the processing buildings. The refinery consisted of 5 concrete chimney stacks, steel and concrete process buildings and a pipe support bridge over a creek. The refinery had live underground jet fuel lines that service the Sydney Airport and had to remain live throughout the project.
The project was completed successfully while maintaining the ongoing services to the Sydney airport and meeting all key performance indicators.
Grid Impact Assessment on Coal Plant Decommissioning
PHILIPPINES
GHD conducted a grid impact assessment on the potential early retirement of a coal-fired power plant in the Philippines. As part of this exercise, GHD provided an assessment concerning the impact of the potentially early retirement of coal-fired power plant in the Philippines on power system security and reliability
Hazelwood Power Station Demolition AUSTRALIA
GHD provided risk management services for targeted demolition activities within Hazelwood Power Station to enable black start capabilities to be maintained. The work included a two-day demolition risk assessment for Engie, including both client representatives and the demolition contractor. Engie’s risk framework was applied systematically to the demolishment of the 50+ year old power station, for associated internal reporting and approval, prior to commencement of demolition. Additionally, a second risk assessment was conducted on a specific building and switchyard that needed to remain intact and ultimately operational on the site to maintain a legislated black start capability. This involved Engie (asset owner), Ausnet (transmission provider) and demolition contractor on the methodology and sequencing to be applied.
AGL Financial Provisioning Reassessment AUSTRALIA
GHD was initially engaged by AGL in the years 2016-17, and subsequently in 2019-20 and 2023- 24, to assist in estimating the appropriate liability provisions associated with the potential closure of AGL-owned power stations, mines, gas and renewable energy facilities including wind, battery energy storaged systems (BESS) and hydroelectric assets. In collaboration with AGL’s technical services, onsite operational, and finance teams, GHD developed a comprehensive understanding of the facilities, supporting infrastructure, and regulatory approvals at AGL’s various sites to inform the provision. GHD’s approach involved reviewing key information such as designs, decommissioning plans, site studies, and environmental assessments. Additionally, site visits, risk workshops, and cost workshops were completed with numerous stakeholders. The collaborative approach with AGL personnel including site visits and workshops provided invaluable information, including qualitative insights from the site personnel’s experience.
Origin Eraring Power Station Closure Cost Estimation AUSTRALIA
Origin Energy commissioned GHD to update its closure provision cost estimates for the Eraring Power Station for 2024. GHD previously estimated these provisions in 2019. Following changes to assumptions of closure strategy, dates, costs, risks, and underlying assumptions, GHD developed an updated closure provision cost estimation to assist with future planning and strategic decision-making. Throughout the project, GHD collaborated closely with Origin Energy to revise the closure base case scenario and related assumptions, as well as to review and test relevant information. This process included updating risk and uncertainty levels, meeting regulatory and contractual closure obligations, and addressing any data gaps.
APA Dandenong LNG Closure Estimates AUSTRALIA
GHD prepared a high-level cost estimate for demolishing an LNG tank and associated materials at the Dandenong LNG facility. We used GHD’s standard demolition cost model and confirmed key assumptions in a workshop. GHD defined the closure scenario for the site alongside key APA stakeholders and considered contingent risks, with the most probabilistic outcomes incorporated into the closure estimate.
Rio Tinto Closure Studies
NEW ZEALAND & AUSTRALIA
In August 2020, GHD was appointed by Rio Tinto to prepare preliminary closure studies for the New Zealand Aluminium Smelter and Bell Bay Aluminium Smelter, following the Closure Study Definition Guidance Note (CSDGN).
