An overview of triple bottom line sustainability in the City of St. Louis

The City of St. Louis harnesses the strength and spirit of its diverse community to create an economically, socially and ecologically vibrant City for present and future generations -- one that dynamically serves those who live, work and play in the City's rich and celebrated historic landscape.

Mayor's Office of Sustainability

The City of St. Louis Sustainability Plan was formally adopted by the City's Planning Commission in January 2013.

The Mayor's Office of Sustainability is seeking sustainability volunteers/interns (unpaid) for 2018 to focus on new climate and urban ecology programs. Please send an email with interest, availability and resume to

In February 2013, former Mayor Slay announced his Sustainability Action Agenda of 29 priority sustainability efforts for implementation by 2018. A City of St. Louis State of Sustainability Report 2013-2016 has been developed to indicate progress made on those 29 Action Agenda items.

STL Climate Initiative

April 2017: A Climate Action & Adaptation Plan for the City of St. Louis Sustainability Plan was developed by Mayor Slay's Office of Sustainability. It contains recommended mitigation strategies for achieving 80% reduction of GHG emissions by 2050, and strategies for being a healthy, resilient, equitable and prosperous community.  

In 2016, the City was recognized with a national City Energy Project award to promote energy efficiency in large buildings. In February 2017, the City passed energy benchmarking legislation targeting existing buildings with 50,000 sq ft. (#70474). The Building Division hosts an Energy Technical Advisor, who supports the City's benchmarking and City Energy Project efforts. Energy Benchmarking information and free training opportunities can be found at

In 2015, former Mayor Slay joined with other local government officials around the world in committing to the Compact of Mayors, and pledging to gather GHG data, set a climate protection target and develop climate plans. The full 2015 GHG Emissions Inventory Report is available, and a 2015 Community GHG inventory summary shows emission trends since 2005. 

The Mayor's Office of Sustainability and Swedish Embassy co-hosted Good Climate is Good Business in 2015 at CORTEX.

Sustainability and the City

The City of St. Louis promotes sustainability in several ways, but is perhaps most visible in its efforts to capitalize on its dense area, existing infrastructure and rich heritage to preserve and restore buildings, many of which possess impressive historic features. Bicycle-friendly streets and widely available public transportation help decrease car usage, thereby reducing emissions and improving air quality. Sustainable practices such as low impact development and residential recycling are encouraged. The City also requires all new municipal buildings to meet energy efficiency and green building standards. With its Habitat for Humanity developments, St. Louis has one of the highest levels of LEED Platinum Homes in the country. St. Louis also ranks among the highest for historic building rehabilitations. The City has been successful in growing its population by revitalizing its downtown and diverse neighborhoods.

The City is moving forward with many important sustainability initiatives. Developing an overarching sustainability framework and climate action plan for the City are two examples of short-term efforts designed to have lasting, measurable impact. Increased emphasis is being placed on celebrating and communicating the sustainability successes of the City and its many partners, as well as expanding upon both current and prior successes in order for the City to become even more vibrant, sustainable and competitive in the years ahead.

The City developed an award-winning Sustainability Plan. The City started a robust public engagement effort in 2011, and issued a Draft For Public Review of its Sustainability Plan in October of 2012.  The City of St. Louis Sustainability Plan is both comprehensive and triple bottom line (economy, ecology, equity) in orientation. More information about the Plan and planning process can be found on the Sustainability Plan tab of this website. 

There have been 3 community-wide Mayor's Sustainability Summits since 2011 (view the program for the 2013 Mayor's Sustainability Summit III :: implement here)
