The Texas Public Policy Foundation (TPPF) is an American conservative think tank based in Austin, Texas. The organization was co-founded in 1989 by James R. Leininger and Fritz S. Steiger, who sought intellectual support for his education reform ideas, including public school vouchers. Projects of the organization include Right on Crime, which is focused on criminal justice reform, and Fueling Freedom, which seeks to "explain the forgotten moral case for fossil fuels" by rejecting the scientific consensus on climate change.
