Sustainable properties

The material factors that guide our investment strategy include:

  • Customer attraction and retention

  • Sustainable design and management

  • Smart energy solutions

  • Climate risk and resilience

  • Carbon reduction strategies

  • Flexible and adaptable properties

The table below includes the specific targets we have adopted in relation to these key business drivers:

GMT’s modern property portfolio is strategically located across Auckland, close to consumers and key transport infrastructure. It provides customers with highly efficient and flexible spaces that help their businesses succeed. 

Maintaining these properties to a high standard and delivering outstanding customer service contribute to the strong relationships that underpin GMT’s financial results. A target occupancy rate above 95% (FY21 average 99%) ensures we are meeting the needs of our customers and developing only to meet demand.

The Trust’s successful development programme is increasingly focused on the redevelopment of strategic brownfield sites, within the portfolio. These innercity properties provide the greatest efficiency for logistics customers focused on last mile delivery, minimising travel distances and carbon emissions from transport. Replacing or repurposing obsolete buildings and remediating contaminated sites improves the quality and performance of existing building stock without consuming additional land, a diminishing resource in a growing city.

Goodman’s base-build specification has been reviewed to ensure our new warehouse and logistics facilities remain industry leading.

They are constructed from sustainably sourced building materials and we manage the development process to reduce waste and other environmental impacts. We work collaboratively with customers and consultants, incorporating the latest technology to maximise the operational performance and energy efficiency of these new buildings.

The redevelopment of Roma Road Estate is the latest example of this focus. The inner-city distribution hub will be a highly sustainable, carbon neutral development. The facilities will be 5-Star Green Star rated and are expected to feature the latest design innovations, including automated LED lighting, rooftop solar-energy systems and EV charging facilities.

Ongoing energy and waste monitoring across the portfolio allow us to benchmark our existing properties, comparing them against best-practice industry standards.

Improving the environmental performance of these buildings, which have an average age of around 12.5 years, continues to be a priority.

Five facilities at Highbrook Business Park are currently included in a pilot study using the Green Star Performance tool. With a baseline assessment of 3 Star (good practice), the rating of these buildings is expected to be improved
to 4 Star (best practice) with building management system optimisation and upgrades over the next two years.

The pilot provides valuable insights into how we can reduce the environmental impact of the existing portfolio.

Goodman’s base-build specification for new developments includes:

  • Energy-efficient design including automated LED lighting

  • Electrical sub-metering for performance monitoring and measurement

  • Charging points for electric vehicles

  • HVAC systems that utilise low emission refrigerants

  • Low-E double glazing to reduce noise and regulate thermal comfort

  • Low-flow water fittings together with rainwater harvesting

  • Use of low volatile organic compound materials and finishes

  • Bike racks and end of trip facilities (size dependent)

Managing climate risk

Acknowledging the threat of climate change, our sustainability programme includes ambitious emission reduction targets that align with the objectives of the Paris Agreement and the limiting of global warming to less than 2 degrees.

Mitigating the impacts of climate change by measuring and minimising greenhouse gas emissions (GHG) has become an essential business activity and we have partnered with Toitū to help us on this journey. With the completion of an audited Emissions Inventory and a detailed Emissions Management and Reduction Plan we have made substantial progress, achieving Toitū carbonzero certification this year.

The certification encompasses Goodman (NZ) Limited, Goodman Property Services (NZ) Limited and Goodman Property Trust. It includes emissions from operational activities and from the buildings and spaces within the portfolio where the Manager has operational control.

Assurance from Toitū confirms our GHG emissions have been measured in accordance with ISO 14064-1:2006 and that we have offset unavoidable emissions with the purchase of New Zealand sourced carbon credits.

The table above details the emissions profile of the business. The largest emission sources include refrigerant losses (HVAC system failures), electricity consumption, fleet vehicle use, corporate travel and waste.

A reduction in refrigerant losses, from 453 tCO₂e in FY20 to 158 tCO₂e in FY21, was the main contributor to the overall reduction in GHG emissions.

While we expect some volatility year to year our target objective is to reduce absolute emissions by 19.4% before 2025 (within five years of the 2020 base year).

This commitment includes improving the performance of the buildings within the portfolio, minimising the energy consumed, the waste produced, and the emissions generated.

With the construction and building sector contributing almost 20% of New Zealand’s emissions the level of embodied carbon within our developments is also being critically assessed.

As part of our commitment to being a sustainable business, new materials and building techniques will be adopted to mitigate these emissions. Future developments will also have the balance of the embodied carbon offset.

Solar energy pilot

OfficeMax is an existing customer that has recently committed to solar energy. The office product and business consumable reseller has had an 880-panel solar array installed on the roof of its warehouse at Highbrook Business Park. With an annual generation capacity of 374,000 kWh the system is expected to provide more than 20% of the customer’s electricity, enough to power 57 New Zealand homes for a year
