Construction is everywhere. On most big city streets, you’ll see new developments and people working to get the next residential development up and on the market, with people moving in.

In July 2017 alone, the U.S. Census Bureau reports that 1.2 million residential building permits were issued, 1.16 million housing projects were started, and 1.18 million housing projects were completed.

What is the impact of producing and transporting materials for so many projects? How will new buildings affect the local environment? How much energy do they require?

As concerns about human impact on climate change grow, so does interest in sustainable building practices.

The U.S. Green Building Council developed the Leadership in Energy and Environmental Design (LEED) certification to provide a framework for businesses and organizations with an eye for sustainability. From concept to conception, LEED certification standards reduce the carbon footprint, energy costs, and overall negative environmental impacts of commercial and residential building projects.

But what cities are doing the best job in sustainable development?

The folks over at ABODO Apartments, took a look at LEED-certified projects nationwide in their latest report and found some very interesting developments.

On a national level, there is more than 1.32 billion square feet of LEED construction. This is nearly enough to cover Staten Island.

When looking at a statewide level, Texas (6,945), California (5,255) and New York (2,215) are leading the charge for total LEED-certified residential projects. And when you take a look at commercial and residential combined, the leader in the clubhouse is Washington, D.C. The city boasts more than 183 million square feet of residential LEED projects and more than 310 million square feet of LEED-certified commercial square feet.

At a city level, the top-10 places with the most LEED-certified residential projects are:

1. Dallas, TX
2. Washington, D.C.
3. Los Angeles, CA
4. Austin, TX
5. New York, NY
6. Cincinnati, OH
7. Seattle, WA
8. Philadelphia, PA
9. Jacksonville, NC
10. Miami, FL

Sustainability is a growing trend, and it’s growing hand-in-hand with new residential development. Although large metropolitan areas like New York and and Washington, D.C., have the most certified LEED square footage, smaller areas aren’t being left behind and are staying competitive with projects per capita.

The future looks pretty green.
