Informed by our double materiality assessment, we have established environmental sustainability commitments in give key policy areas: climate change, energy, water, materials and resource circularity and biodiversity.

Climate Response
GPT considers and assesses the economic, environmental and social risks associated with climate change and nature degradation in relation to its business operations and strategy. We are taking steps to reduce our environmental impact, decarbonise our portfolio and mitigate the potential impacts of climate and nature-related risks on our business.
GPT values environmental sustainability by driving efficiency and reducing resource consumption and pollution associated with our operations, where possible. We are also investing in restorative offsets. In developing our strategies and policies on climate and nature, we consider industry relevant goals and targets of international agreements such as the Paris Agreement.
We integrate climate risk assessment and management into our operational, development and investment decision-making. Climate change impacts are examined across different time horizons, considering both high and low emission scenarios. We evaluate climate-related risks on GPT’s assets, including extreme weather events, transitional risks stemming from policy shifts and market changes, as well as opportunities that may arise from being proactive in this space.
For further details about our climate response, see our 2024 Climate and Nature Disclosure.
GPT’s Net Zero Plan
Our Net Zero Plan for an orderly transition to a resilient, low carbon economy, includes both decarbonisation goals with certified carbon neutral milestones and goals to improve climate resilience. GPT has set and is delivering on carbon neutral milestones for all material emissions (Scope 1 and Scope 2) where we have principal decision-making authority.

Energy
GPT is focused on five key areas to advance our decarbonisation.
- Energy efficiency remains a core priority. We monitor energy consumption, optimise building systems to maximise efficiency while maintaining occupant comfort and establish site-specific targets which are reviewed and monitored through audits, monthly and quarterly assessments. We also provide training and support to employees responsible for delivering key objectives, design for efficiency in new developments, and plan for lifecycle upgrades.
- On-site solar photovoltaics (PV) have been installed on a range of GPT assets, and we manage renewable energy certificates.
- Offsite renewable electricity is central to our approach, including a focus on renewable base building electricity contracts. GPT manages its own renewable energy certificate registry with the Clean Energy Regulator in alignment with the Greenhouse Gas Protocol market-based carbon accounting practice.
- Through the electrification of our buildings, we aim to eliminate the use of fossil fuels in our buildings by upgrading electrical heating systems at lifecycle and development opportunities.
- We target the use of low global warming potential (GWP) refrigerants by monitoring supplier contracts and ongoing equipment maintenance.
As well as targeting carbon neutrality, we’re reducing emissions from our energy use where we can by managing costs, improving demand flexibility, and investing in storage and backup systems.
GPT has partnered with Shell Energy to participate in demand management programs supporting a number of GPT’s Office and Retail assets to install Smart Energy Hubs which include on-site solar generation, batteries and Loadflex processes to adjust our demand profile in response to market events.
See our Sustainability Data Dashboard for how we monitor and report on our energy performance. See our 2024 Climate and Nature Disclosure to learn more about our energy management programs and outcomes.
Water
GPT is focused on potable water consumption in our assets and seeks to reduce consumption through water efficient design and management practices, including the use of recycled water.
Our actions include ensuring high efficiency fixtures in our assets, which are reviewed regularly for upgrades as part of lifecycle planning. We also prioritise the reuse of stormwater and grey water and implement onsite wastewater treatment to supplement potable water, where possible, in new developments and retrofits. In addition, we provide water meters for tenants to track and manage consumption.
See our Sustainability Data Dashboard for how we monitor and report on our water consumption.
Materials and circularity
GPT supports a shift to a circular economy through our efforts to minimise the waste we produce and maximising the lifecycle of materials. This includes eliminating waste where possible, considering materials selected for in our projects and taking steps to recover (or reprocess) everything in our control to its highest value. This approach also reduces the amount of waste sent to landfill, which is the principal source of Scope 3 emissions from our building operations.
GPT is focused on addressing materials and waste impacts in two areas:
- Operational waste generated by building occupants is managed through stakeholder engagement, including tenants, cleaning contractors and other supply chain partners, to implement waste recovery and source separation training programs. We set and report on waste targets, work with GECA Waste Collection Services Standard certification contractors, and participate in the NABERS Waste Rating.
- Construction materials and waste are managed by specifying materials in project design, collaborating with builders and contractors to enhance material reuse and recycling, implementing waste management plans across all projects, and providing education and training to our employees and contractors.
See our Sustainability Data Dashboard for how we monitor and report on our waste performance.
Biodiversity and nature
GPT takes action to understand and manage our biodiversity impacts and opportunities through our asset management activities, governance practices and stakeholder engagement. This includes project specific actions such as asset-based biodiversity assessments and management plans, sustainable sourcing in procurement, as well as establishing natural capital accounts and supporting learning and innovation with our people and external stakeholders.
We have also assessed our broader nature-related risks and opportunities in the context of our direct operations and upstream supply chains, including materials, utilities and land.
See our 2024 Climate and Nature Disclosure for more information.
Metrics and targets
GPT receives assurance over our environmental performance metrics and uses a number of third-party ratings and certifications, including NABERS, Greenstar and Climate Active to validate our buildings’ environmental performance.
See our Sustainability Data Dashboard for GPT’s sustainability performance metrics and targets, including building ratings and certifications.
