“As we embark on a new decade, the USGBC community is focused on helping more projects get on the path to LEED certification and a more sustainable future,” said Mahesh Ramanujam, president and CEO, USGBC. “Over the last year, the Top 10 states have certified projects that serve as incredible examples of how green building can create more sustainable and resilient spaces that improve our living standard. There is still much work to be done, but the progress made across these states shows us that our work is having a tangible impact on people’s lives. As we enter our next chapter, we are committed to helping more buildings, cities, and communities improve their sustainability performance through LEED.”

LEED-certified projects support personal health and well-being as well as use less energy and water, reduce carbon emissions, and save money for families, businesses, and taxpayers. The Top 10 list is based on 2010 U.S. Census data and includes commercial and institutional green building projects certified throughout 2019. Colorado certified 102 green building projects representing 4.76 square feet of LEED-certified space per resident. The state has made the Top 10 list each year but jumped to the top spot after ranking sixth in 2018. Minnesota and Oregon reemerged as Top 10 states after missing the list last year, coming in at number eight and nine respectively.

USGBC calculates the list using per capita figures to allow for a fair comparison of the level of green building taking place among states with significant differences in population and number of overall buildings. Despite Washington, D.C., not appearing in the official Top 10 list because of its status as a federal territory, it consistently leads the nation, and, in 2019, D.C. certified 52.86 square feet of space per resident across 143 green building projects. The nation’s capital has a strong legacy of sustainability leadership and has expanded its use of LEED from buildings to cities and communities to support its goals. In 2017, it became the first LEED-certified city, and, in 2019, it certified the Golden Triangle Business Improvement District LEED Platinum, the first business improvement district in the world to certify.

With green building expected to grow globally through 2021, the need for skilled professionals to support green building projects has never been more important. Across the U.S. there are more than 165,000 LEED green building professionals with the knowledge to help cities and communities transition to greener buildings and spaces. LEED professionals demonstrate a competency in green building principles that can set projects on the path to certification and help them consider ways to reduce their impact on the environment and provide people with healthier, more sustainable spaces to live, learn, work, and play.

As USGBC continues to advance green buildings, cities, and communities through the adoption of LEED and the latest version of the rating system, LEED v4.1, the organization is also considering a future that is focused on a more regenerative approach.

In November 2019 at the annual Greenbuild International Conference & Expo, USGBC introduced LEED Positive – a roadmap that will lay the foundation for a future of LEED that transitions away from strategies that only reduce harm and instead focus on those that help repair and restore. With a continued focus on performance, USGBC is laying the groundwork to ensure sustainable design, construction and operations of buildings, cities and communities remains focused on better buildings that contribute to better lives.
