Can't we just keep building greenfield/outer suburban developments?

When compared to densifying inner suburbs, the status quo of relying on greenfield developments to take the bulk of Victoria’s housing growth results in worse outcomes for residents, the city, and the environment.

Greenfield households emit an additional 4.4 tonnes of carbon dioxide annually than equivalent infill counterparts. It has been substantiated numerous times (Minx et al. (2013), Ala-Mantila et al. (2014) and Muñoz et al. (2020)) that urban living in developed economies produces the smallest relative carbon footprint. A major contributing factor to the differential gap in carbon footprints is the urban fringe-induced car reliance.  

A survey on people who moved to greenfield sites in Sydney showed that after relocating to greenfield sites, one-way commute times blew out from 34 minutes to 50 minutes which was “significantly associated with lower mental health scores and decreased [measurement] of subjective wellbeing”. The same study found that after moving to a greenfield site, car usage as a proportion of mode of transport increased significantly at the expense of public and active transport. This means that greenfield developments force their residents into worse commute times and physical and mental health outcomes.

The nature of greenfield developments means unlike infill developments, there little to no infrastructure is present in these regions before they’re redeveloped—however unlike in established suburban infrastructure, the relative costs of delivering it cost substantially more. An Infrastructure Victoria analysis suggests that infrastructure to support new greenfield homes can cost up to 4 times more than in established suburbs. This in essence means that low-density inner-city living is subsidised excessively by taxpayers paying high premiums for outer suburban infrastructure.

Newer greenfield sites are also often located in areas with much higher flood and fire risk. As the National Growth Areas Alliance stated: “we're building right on the outskirts of the city in places more vulnerable to climate change and natural disasters and yet we're putting thousands and thousands of families into new houses there every year.” Furthermore, urban sprawl is pushing further and further into Victoria’s food bowl areas which produce almost half the vegetables grown in the state. 

Lastly, one of the core reasons people choose to live in outer suburbia is the relatively cheaper housing costs—however, once you factor in transportation costs, the cost-benefit vanishes. Research suggests due to the aforementioned car dependency of greenfield areas combined with the lack of public transport options, residents face not only higher base transportation costs but are more sensitive to fuel shocks. 

All this forces us to ask: are the numerous trade-offs associated with greenfield developments worth it?

For Melbourne to grow sustainably it has to grow up, not out.
