Many homes, parks and businesses in US cities stand on former manufacturing sites that may have left legacy hazardous wastes behind. A new book calls for more research into our urban industrial past.
Planning innovations around the world offer inspiration, but ultimately the innovations needed to make Australia’s sprawling cities more sustainable must be shaped by local conditions.
Rising e-commerce means more delivery trucks and urban gridlock. Lockers at transit centers, where carriers can leave packages for people who live or work nearby, are a potential solution.
The private car is the default transport option for many families. This reduces physical activity and increases greenhouse gas emissions, with unhealthy results for their children and the environment.
The city where the Kyoto Protocol was signed resolved some years ago to move away from cars and towards low-emission alternatives for getting around. And it’s making real progress towards that goal.

Australian cities are world-leading – in the worst sense – for resource use and greenhouse emissions. China-born residents have embraced these consumption patterns, which is bad news for the planet.
Barangaroo is an example of a development with admirable green credentials, but it is also an exclusive precinct that has played a role in displacing the disadvantaged from this part of Sydney.
Australia has yet to properly acknowledge that the Sustainable Development Goals aren’t just an issue for other countries. The problems that demand our attention are much closer to home.
Taking this step may improve the quality of life for vulnerable people and reduce the amount of air conditioning they use, making their neighborhoods less prone to power outages.
Many US cities are investing in bike infrastructure and shade trees. Properly located, these additions can make streets cooler, cleaner and safer for all users – even those who drive.
In many US cities, ride-hailing apps are luring riders away from public transit and increasing traffic congestion. But with the right rules, they could enhance public transit instead.
There’s no such thing as a one-size-fits-all plan for sustainable, healthy urban living. Urban diaries help identify what works – and doesn’t work – for tropical cities like Cairns or Townsville.

In an increasingly urban world, trees can make a major difference. One study found that, for every dollar invested in planting, megacities saw a $2.50 return on their investment.
Dozens of US cities have launched bike-share programs in the past decade. There have been bumps – critics want wider access, and cities want bikes stored out of the way – but bike sharing is on a roll.
Gentrification is not the only path for improving urban neighborhoods. A cleanup in Brooklyn and Queens offers another, more inclusive model that scholars have dubbed ‘just green enough.’
New York soon may charge a fee to drive into central Manhattan as a way of reducing traffic and raising funds for public transit. An urban scholar says this step is overdue in the United States.
