Green Cities Make People Happier and Healthier

Live Science reports on a study that people feel enhanced well-being in cities with more green space.  It’s clear that green cities are not just more pleasant; they’re good for us! Green cities make people happier and healthier.

Here’s another example. And another from a post I wrote in 2012.

So what do we do to create green cities? Lots of things, but one of the most crucial is improving the urban forest.

Greener Cities Are the Future of Sustainable Living

You’ve probably seen some of the lists of “best places” compiled by various magazines. Outside, Money, and others compile their lists based on their idea of relevant criteria. You see a lot of repeat winners, with Madison, Wisconsin, as a perfect example. It routinely wins a place on both lists.

I like the Outside list, as it shows cities and towns developing new amenities for recreation. What’s especially interesting is towns like this year’s winner, Richmond, Virginia, that have cleaned up previously polluted land and rivers. The James River, for example, was closed to fishing for 13 years due to extreme pollution. After extensive cleanup work, it’s now a recreational hub.

Another approach to list-making is evaluating and improving the sustainability of cities. As more than 80% of Americans and Canadians are now urban dwellers, it’s clear that cities have a major positive impact on the environmental health of our world, and on our people. Greener cities are the future of sustainable living

It may seem counter-intuitive that cities can be centers of sustainable living—in contrast to living on the land and growing your own food, and so on—but it makes sense when you think about it. When people live in dense cities, they need to drive less—or not at all—to reach all the places they need to go. Delivery of goods and services is more efficient when more people are clustered together. Housing is more efficient on multiple levels with shared walls, for example, than having a home with four walls losing heat to the outside. Food is grown where there’s room to grow a lot efficiently, then transported to the mass of buyers. Waste is a resource and can be re-used or recycled. And cities draw people from the countryside and lessen humans’ daily impact on some rural areas.

So looking beyond simple measures of what we like in a place, such as good schools, outdoor recreation, and short commutes, what makes a place sustainable? And what are the most sustainable cities?

Siemens Green City Index rates 9 criteria

One measure is the Green City Index, developed by Siemens Corporation and the Economist Intelligence Unit. They applied these 9 criteria to cities all over the globe:

  • CO2
  • Energy
  • Land Use
  • Buildings
  • Air
  • Water
  • Waste
  • Transport
  • Environmental Governance

In North America, the top four most sustainable cities, of 27 evaluated, were San Francisco, Vancouver, Seattle, and New York City. This is a useful metric, but cities also have a huge negative impact on the natural world. Bulldozing an entire field and building apartments and offices, even densely, removes wildlife habitat, as well as plants that absorb CO2 and produce oxygen. How do cities mitigate this destruction?

What’s missing from sustainability ratings

This blog at the Sustainable Cities Collective discusses adding more green elements to those sustainability scores, such as green-space percentage, natural areas, and biodiversity. Adding those elements to a sustainability ranking will add to people’s consciousness of their importance.

And why are they important? Green space not only makes our cities look better, people feel less stressed, the heat island effect decreases, plants clean the air of pollutants for us, trees add to property values, and provide a host of other benefits.

Green space, street trees, and natural areas can remediate pollution to create healthier, more enjoyable, more sustainable cities, while they also become the places where we play.
