The debate about the transition away from fossil fuels has focused on costs, but right here in Australia we have examples of the benefits of sustainable new energy sources for our cities.
Leonardo da Vinci's ideal city contained design features and engineering works not realised until hundreds of years after he died.
Trees clean urban air, store carbon, slow floodwaters and can be used to design safer streets. Scholars are starting to calculate what these services are worth – a fitting topic for Arbor Day.
Rather than mourn the end of a seven-year reign as 'world's most liveable city', Melbourne could raise its sights to become more liveable, healthy and sustainable for all who live in the city.
Starting in 2021, drivers will pay a fee to enter midtown and lower Manhattan during busy times of day. Will this clear New York's air and streets?
US cities were designed and engineered around cars. Now some are working to increase walking and biking, but the shift isn't easy.
Urban farming can make it easier for city residents to obtain healthy, affordable food. But to raise big yields from small pieces of land, farmers need training and support.
Minorities are driving the bicycling boom, but bike infrastructure investments often neglect their needs. A new study explores what riders in low-income and minority neighborhoods want.
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.
