Jennifer Buffett is Co-Chair and President of the NoVo Foundation (Latin: create, change), a philanthropic organization focused on creating a more just and balanced world based on cooperation and partnership, primarily through the empowerment of girls and women. She oversees the foundation's strategic direction as defined by herself and her husband, composer and producer Peter Buffett.

NoVo works to achieve its vision by transforming social attitudes, relationships, and institutions that perpetuate injustice – primarily through the empowerment of girls and women. NoVo aims to unlock the potential of girls and women to be powerful agents of change, and help children grow into caring adults skilled at working cooperatively. The foundation approaches this effort by investing in long-term strategic initiatives that lead to systemic change, specifically ending violence against girls and women, unlocking the potential of adolescent girls, and advancing whole-child education and social and emotional learning.

NoVo is a major philanthropic partner with the Nike Foundation, fueling "The Girl Effect" – the social and economic change brought about when every girl has the power to participate equally in her community.

Jennifer and Peter are recipients of the Clinton Global Citizen Award for their "visionary leadership and sustainable, scalable work in solving pressing global challenges."

The Ms. Foundation for Women honored Peter and Jennifer's philanthropic boldness and commitment with a 2010 "Gloria Steinem Award." Barron's ranks them in the top 25 list of most effective philanthropists. In 2010, Jennifer was selected by President Clinton to be a founding member of the Clinton Global Initiative's young global leaders cohort, "CGI LEAD."

In addition, Ms. Buffett provides leadership and serves on the boards of the Nike Foundation, V-Day, CASEL (Collaborative for Academic and Social and Emotional Learning), BRAC USA, the International Center for Research on Women, and "Women Moving Millions."

Jennifer's work in philanthropy began in 1997 when Peter's parents, Susan and Warren Buffett, bequeathed Jennifer and Peter a small charitable fund.
