Founded in 1926 by the late Charles Stewart Mott, the Charles Stewart Mott Foundation (CSM) is a left-of-center grantmaking foundation that funds organizations and communities in four strategic subject areas: local issues related to Flint, Michigan; civil society; education; and the environment.  At its inception grants were focused in the United States, but it has expanded internationally with offices in three countries and grants made in 62 nations. 
Founded by Charles Stewart Mott and funded by wealth earned from General Motors stock, Mott’s original intent was to benefit the community of Flint, Michigan, where his business relocated in 1906 with grants focused to encourage the community and individuals to participate in their own development. 
Today the Mott Foundation invests in four primary areas; The Flint area, the environment, education, and civil society. 
In 2016 Mott Foundation made a five-year, $100 million commitment to the Flint area designed to revitalize downtown, improve the environment, get the community involved and raise the education levels of its people. 
Support for organizations like the radical environmentalist group Friends of the Earth, the liberal funding conduits Tides Foundation and Tides Center, anti-energy group Oil Change International, Hispanic identity politics faction UnidosUS (formerly the National Council of La Raza), the Civicus World Alliance for Citizen Participation, liberal “dark money” group NEO Philanthropy, and left-wing think tank Center on Budget and Policy Priorities are indicative of the Mott Foundation’s left-of-center grantmaking.

In 1931 Charles Stewart Mott acquired U.S. Sugar and later transferred ownership to the Charles Stewart Mott Foundation. In 1933 he transferred all but 35% of the foundation’s interest to the Mott Children’s Health Center as required by the IRS. Today the company is an ESOP (Employee Stock Ownership Plan) with the foundation (19%) and the health center (22%) continuing to hold control. Today, the Mott Foundation values its ownership interest at $153,547,300, a value discounted by $30,709,460 due to the privately held nature of the stock. 
Two controversies surround the company. First, is the concern over pollutants sent downstream by the sugar company to the Everglades and the communities and beaches that are south of the farm.  U.S. Sugar has worked with the state and federal governments to ameliorate the pollutants in the water sent south and continues to do so. 
Second, employee members of the ESOP filed a lawsuit in 2008 claiming that they were economically harmed by the company and foundation’s failure to inform them of an offer to buy U.S. Sugar. The company’s CEO stated in an interview that the offer was too low to present to shareholders..  All parties settled the case in 2009 with no party admitting wrongdoing.
