How the house and car nexus is destroying biodiversity

"Australian houses are among the largest in the world, averaging 236 square metres of living space"

"Local urban greening outcomes are subjugated to state government housing priorities."

"Driveway area has increased on average by 57% from 29m2 to 46m2."

"Front garden area has reduced on average by 46% from 102m2 to 55m2."

"Redevelopment has reduced canopy cover by 62% at the lot scale."

"Middle-ring suburban Sydney is experiencing a quiet yet profound transformation. As redevelopment accelerates, larger houses with expansive footprints and additional driveways are steadily replacing traditional front yards and gardens. This study examines 370 properties across Northern and Greater Western Sydney to quantify these changes. In areas where older, low-density homes have been replaced by newer, larger detached dwellings, the average front garden area has declined by 46%, while driveways and other impervious surfaces have increased by 57%. Most notably, front yard canopy cover has fallen by 62%. These patterns are not due to a lack of policy, but to a planning system in which local controls have become discretionary under ongoing state-level legislative reforms. Broader social trends toward larger homes and greater car ownership further reinforce this shift. The cumulative effect is leading to a substantial loss of private green space, contributing to higher urban heat, reduced biodiversity, and diminished connections with nature. Urban planning reform is urgently needed to embed minimum standards..."

Turning gardens into roads - Supersized driveways are shrinking suburban front yards

"...In 30 years time we’ll suddenly wake up and go ‘Where have all our front gardens gone?’..You end up with this hard infrastructure – houses and driveways – that have this incremental dominance of the landscape."

"Tree canopy coverage was reduced by 62% as older houses were demolished and rebuilt."

"In contrast, the footprint of driveways and other artificial surfaces increased by 57% to 46 square metres."

"...Greater car ownership and households increasingly having multiple vehicles had also contributed to the loss of private green space.The loss of private green space contributes to higher urban heat, reduced biodiversity, and fewer connections with nature..." >>

Urban Heat

🌡️ HEAL project featured on Climate Adaptation Stories!

Urban heat islands challenge pedestrian mobility, especially for vulnerable groups. Our HEAL project uses participatory research & data-driven solutions to address heat stress.
The app calculates heat-avoidant routes using real-time sensors, shadow modeling & community input. Now expanding across Europe!

Contact us if your city could benefit from heat-resilient routing.

GOOD THREAD: One more consequence of too many parked cars in cities (and one more reason to replace surface parking with trees and people-places). All those parked cars are making hot cities even hotter. (at a minimum, choose a white car.) #UrbanHeat

Atlanta is embracing a cheap, effective way to beat urban heat: 'cool roofs'

White or reflective roofs significantly reduce temperatures. Atlanta is the latest city to mandate their adoption.

“Researchers have been saying for nearly 25 years that our Building Code needs to include standards for cooling homes…We’ve got to see a regime where people aren’t being cooked alive in their own house.” We badly need cooler homes by design as our cities, and world, gets hotter. #UrbanHeat

🌍 Pushing #ClimateModeling to the Next Level

What happens when you run global climate #simulations at the kilometre scale for multiple years

In our latest blog post, we share insights from a landmark #nextGEMS study using ECMWF’s Integrated Forecasting System coupled to high-resolution ocean–sea ice models.

These simulations capture fine-scale processes—from mesoscale #OceanEddies to #UrbanHeat patterns—that coarser models can’t resolve, offering a more realistic picture of our climate system. Along the way, the team tackled key challenges, from water and #EnergyConservation to improving the simulation of #ExtremePrecipitation and polar sea ice leads.

💡 The results point towards more accurate, actionable climate information—but also highlight the huge computational demands of this frontier.
