New research quantifies the economic benefits of urban trees:

“Every tree in urban Tennessee provides an estimated $2.25 worth of measurable economic benefits every year. Might not seem like a lot, but with 284 million urban trees in the state, the payoff’s pretty big.

Through energy savings, air and water filtering and carbon storage, the urban trees of Tennessee account for more than $638 million in benefits, according to a report [PDF] conducted by the Forest Service of the U.S. Department of Agriculture and released earlier this year.”

Sustainable is not enough: a call for regenerative cities | The Global Urbanist

Urban resource consumption and waste disposal is widely seen as the root cause of many of the world’s environmental problems. Because so much damage has already been done to the world’s ecosystems, and solutions need to be found to reverse it, we need to start thinking of regenerative rather than just sustainable urban development.

Since the industrial revolution the process of urbanisation has become ever more resource-intensive, significantly contributing to climate change and to the loss of soil carbon, the natural fertility of farmland, and the world’s biodiversity. Our ravenous appetite for resources from the world’s ecosystems has severe consequences for all life on Earth, including human life. Cities have developed resource consumption and waste disposal habits that show little concern for the environmental consequences.

Fortunately in some places this seems to be changing. In the past decade concepts that capture the idea of how to future-proof our cities have arisen worldwide: smart cities, liveable cities, sustainable cities, intelligent cities, resilient cities.

Are Green Buildings Truly Sustainable? | This Big City
With the built environment accounting for over 40% of global  carbon emissions, sustainable buildings seem like an obvious place to  start as COP17 continues to address climate change. But is the trend for  ‘green’ buildings resulting in truly sustainable alternatives? Mayra Hartmann of Future Cape Town investigates.
A few weeks ago the GBCSA hosted its annual conference.  The topics were plentiful and there was a certain buzz in the air.  Unfortunately, I was only able to attend the afternoon sessions, but  nonetheless I was able enjoy the whiff of green air. There was an  eclectic mix of developers, designers, planners and even psychologists  discussing an array of topics, however a few major developments and  ideas were presented. As someone that follows the industry, the ideas  were not brand new, but the fact that they were discussed in such close  proximity was cause for lively discussions.
The discussions and presentations concentrated on three aspects of building;
the building itself
the effect of green design on office inhabitants and;
its integration with its surroundings.
The design feature that seemed to be particularly popular was the use  of large central atriums to promote natural light and airflow within  the building, something South Africa’s two highest rated green star  buildings both make use of. Atriums are also effective at reviving old  spaces. Chris Jofeh from Arup described the companies “cut and carve”  approach when retrofitting old offices and that atriums were an ideal of  way opening up and lighting an otherwise dull space. And dull spaces  don’t make for a good working environment.

Shopping Centers for Cutting Transportation Emissions

Many people use them, so why not make them more about community and more sustainable. I am talking about Shopping Malls. You get in your car, drive over, try to find a parking spot, get stressed out, and finally leave. What if malls were located on pedestrian streets that were easily accessible by bike, walking, and public transportation. Malls receive high traffic. By making them along pedestrian streets, you encourage the act of walking to them rather than driving to the mall. (If you look at maps, parking accounts for a vast portion of malls’ property.) 

Peter Calthorpe on ‘Resilient Cities: Urbanism in the Age of Climate Change’

From the California Academy of Sciences, via Fora TV:

This event is the second part of a two-part discussion featuring Bay Area architect and planner Peter Calthorpe, author of Sustainable Communities and Urbanism in the Age of Climate Change, discusses the aspects of a livable city.

Click here for part 1 featuring Timothy Beatley, author of Biophilic Cities and Resilient Cities. For more from Calthorpe check out his interview with Grist where he explains ‘Why urbanism is the cheapest, smartest way to fight climate change’.

Tube City: A sustainable water-purifying city for Delhi

Tube City is a design for a 21 km long tube running over the Yamuna River in the city of Delhi. Conceived by Abhinay Sharma, the tube itself would be a living sustainable city with in-house farms and residential, commercial and office zones. A central metro spine and road network would keep the tube well connected, and the structure could also draw in water from the river for purification and consumption.
