The Alliance for Sustainable Colorado received 501(c)(3) status from the IRS in June 2004. Later that year, the organization purchased a 100-year old warehouse building and adjacent empty lot in Denver’s historic Lower Downtown (LoDo) district and created the Alliance Center, Denver’s multi-tenant nonprofit center for organizations working on sustainability issues. The Alliance Center was renovated “Green”, becoming the first historic building in the country to earn two Leadership in Energy & Environmental Design (LEED) certifications, one for Existing Building (Gold) and the other for Commercial Interiors (Silver). It now provides offices, meeting space and shared services to a community of nonprofit tenants. The building creates synergies and fosters partnerships that accelerate progress on issues that affect the People, Planet, Profit practice, ensuring consideration of impacts on Colorado’s people, environment, and economy.


The mission of Alliance for Sustainable Colorado is to advance sustainability through collaboration among nonprofits, business, government and education.


Collaboration and the people, planet, profit practice, long-term perspective, are the central foci of our work.  We have deep commitment to sustainability and consider the impacts of decisions made today on future generations.  We believe that for decisions to achieve sustainability, they should have input and buy-in from many perspectives.  We are nonpartisan, broadly inclusive, promote diversity and lead by example.
