Location: The Overlooked Key to Truly Sustainable Property Development
In the realm of property development, sustainability conversations typically revolve around well-known elements such as solar panels, water-efficient fixtures, energy ratings, and recycled materials. These components are undoubtedly important and signify real advancements in minimizing the environmental impact of buildings. However, these discussions consistently miss addressing the single most critical factor that determines a dwelling's carbon footprint over its entire lifetime: location.
The Impact of Location on Carbon Emissions
Where people choose to live fundamentally shapes their travel patterns for decades. Research from the Bankwest Curtin Economics Centre (BCEC), detailed in its publication Perth’s Infill Housing Future, reveals that residents in car-dependent outer suburbs produce nearly double the annual greenhouse gas emissions compared to those in inner-city locations. This disparity is primarily due to transport-related energy use, which compounds daily across multiple residents throughout a building's operational life.
Perth, according to Real Insurance’s Real Commute Report 2025, holds the record for Australia’s longest average daily commute at 38 kilometers. This distance has a profound effect on the sustainability of dwellings, yet planning frameworks and green building certifications tend to prioritize building performance while treating location as a secondary concern. As a result, developments can earn sustainability accolades while inadvertently forcing residents into car-dependent lifestyles that generate substantial ongoing emissions.
Infrastructure and Environmental Costs
Every new suburb necessitates extensive infrastructure, including kilometers of roads, water pipes, sewerage systems, and electrical networks, all of which contribute significantly to carbon emissions. The same BCEC research found that automobile-oriented suburban fabric requires 288 tonnes of basic raw materials per person in infrastructure, in stark contrast to just 147 tonnes for dense walking-city fabric.
Infill development in established areas leverages existing infrastructure, meaning the embodied carbon cost has already been incurred. Additional dwellings in these locations represent only marginal increases to network capacity, rather than requiring wholesale new construction. This approach not only reduces carbon emissions but also minimizes resource consumption and environmental disruption.
Benefits Beyond Carbon Reduction
Proximity to employment, services, education, and amenities does more than just cut carbon emissions; it also reduces the time spent traveling. These saved hours have significant quality-of-life implications that extend beyond environmental considerations, yet they stem from the same fundamental source: whether development occurs in locations where people actually need to be.
Dense urban living further decreases per-dwelling land consumption. Every apartment building constructed in an established suburb represents land that remains untouched on the urban fringe, preserving native vegetation and biodiversity. This conservation effort is crucial for maintaining ecological balance and supporting sustainable urban growth.
Challenges and Realities in Planning
While Perth’s planning frameworks acknowledge the importance of infill development, community resistance and regulatory complexity often make fringe development more feasible, despite its greater environmental cost. This paradox highlights a critical gap in current sustainability practices.
Green building features deserve ongoing attention and improvement, but they cannot compensate for the carbon cost of a poor location. The most sustainably constructed dwelling in a car-dependent area will inevitably generate more lifetime emissions than a modest apartment in a walkable neighborhood. Genuine sustainability requires confronting this reality head-on. For the majority of developments, location determines environmental performance more than any other single factor, making it an essential consideration for future planning and policy reforms.
