  • Mission:
  • To advance sustainability through collaboration among non-profits, business, government, and education; and to foster a culture of sustainability with long-term perspective, regard for future generations' welfare, and a balanced focus on social, environmental, and economic impacts of sustainability.

  • Overview:
  • The Alliance for Sustainable Colorado (“Alliance”) was established in 2004. Based in Denver, Colorado, our mission is to advance sustainability through collaboration among nonprofit, business, government, and education leaders. Our organization and mission grew out of a deep conviction that the habitability of the Earth is in danger and that collective action across all sectors of society is required to mitigate this risk. We believe that integrated planning, which brings people from the private business, non-profit, government, and education sectors together, is the best way to advance sustainability. The Alliance is the only statewide sustainability organization to engage in a truly cross-sector approach in collaborative problem-solving. We strive to be nonpartisan, broadly inclusive, and to lead by example. 

    The Alliance for Sustainable Colorado has three program areas: The Alliance Center, a multi-tenant nonprofit center for organizations working on sustainability issues; Public Policy, which advocates for policy change across Colorado to promote sustainability; and Education and Outreach, which brings together a statewide network of business and community leaders in conversations about sustainability. 

    1. The Alliance Center – In 2004, the organization purchased a 100-year old warehouse and adjacent empty lot in Denver’s Lower Downtown Historic District and created the Alliance Center, a multi-tenant nonprofit center for organizations working on sustainability. The Center was extensively renovated to green standards, becoming the first historic building to earn two U.S. Green Building Council LEED (Leadership in Energy and Environmental Design) certifications – Existing Buildings Gold and Commercial Interiors Silver – along with U.S. EPA Energy Star Leader status. The Center now provides offices and meeting space (at below-market rents), operations support, shared services and a culture brimming with opportunities for collaboration to a community of more than 30 diverse nonprofit tenants, all focused on some aspect of social, environmental and/or economic sustainability. The Center is a physical and intellectual hub for the statewide sustainability network being fostered by the Alliance, and each year more than 1,000 visitors are led on guided tours of the Center to learn about green building features, sustainability issues and solutions, and experience collaboration in action. 

A series of renovations designed to improve the quality of the facility available to our nonprofit tenants will be implemented over the next three years beginning in 2013.


Education and Outreach – Through its Education and Outreach program, the Alliance brings together an extensive statewide network – The Colorado Sustainability Collaborative – of key community players focused on the best policies and practices of sustainability. In Regional Roundtable meetings, educational events and informational resources, our efforts combine the wisdom and lessons of all participants to turn barriers into solutions – from local food production, recycling, and renewable energy financing, to efficient zoning codes and green jobs training. The program has catalyzed the establishment of 18 Regional Sustainability Councils across the state, with three more under development. These councils are comprised of non-profit, business, and local government leaders and citizens that work together on regional and statewide goals.


3. Public Policy – The Public Policy program is the means by which the Alliance and its partners, including tenants in the Alliance Center, advocate for sustainability in state and local policies by energizing coalitions, initiating legislation, arranging expert testimony to educate legislators, and connecting communities with their policy makers to engage constituents in the legislative process. Past successes include shepherding into law legislation requiring energy and resource efficiency in state-funded building projects, including low-income housing.

  • History:
  • 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 district and created the Alliance Center, Denver’s multi-tenant nonprofit center for organizations working on sustainability issues ranging from food production to clean energy. 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 Colorado’s people, environment, and economy.
