Colorado, Illinois, New York Lead Nation In LEED Green Building

Massachusetts and Hawaii round out Top 5 on USGBC's Top 10 States for LEED, which recognizes current leaders committed to sustainable buildings, cities, and communities.

For the first time since 2011, Colorado has earned the top spot on the U.S. Green Building Council (USGBC) annual list of Top 10 States for LEED green building, which ranks states based on the number of LEED certified square feet per person. LEED (Leadership in Energy and Environmental Design) is the most widely used green building rating system in the world with more than 100,000 projects engaged. This year’s top 10 states are home to more than 105 million people, including more than 80,000 LEED green building professionals with the skills to support the sustainable transformation of buildings.

“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. The full rankings are as follows:

LEED Green BuildingDespite Washington, DC not appearing in the official Top 10 list because of its status as a federal territory, it consistently leads the nation and in 2019 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 certified the Golden Triangle Business Improvement District LEED Platinum, the first business improvement district in the world to certify.
