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.
Australia’s sprawling cities present many challenges to sustainability, but planning innovations can help achieve at least half of the UN Sustainable Development Goals.
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.
Children’s travel needs are a big factor in private car use.
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.
Most of Kyoto’s narrow streets could become no-car zones.
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.
Conspicuous consumption is one of the main ways that China-born migrants come to mirror Australian society.
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 a development on Sydney Harbour with strong green credentials, but it’s overwhelmingly the well-off who enjoy the benefits.
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 is a long way from achieving responsible consumption and production – SDG 12 – and China exposed the reliance on shifting the problem elsewhere when it stopped accepting waste for recycling.

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.
Planning and design for healthy, liveable communities in the Australian tropics can involve quite different considerations from those that apply down south.
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.
For a megacity, Tokyo is rich in trees.
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.
