Political career
Beginnings in state politics
As a Green Party politician, Hermann was elected to the Landtag of Baden-Württemberg in 1984, of which he was a member until 1988.
From 1992 until 1997, Hermann served as co-chair of the Green Party in Baden-Württemberg, alongside Dagmar Dehmer (1992–1993) and Barbara Graf (1995–1997).
Member of the German Parliament, 1998–2011
In 1998, Hermann was elected to the Bundestag. He was an MP of the Bundestag until 2011. In this capacity, he served as deputy chairman of the Committee on the Environment, Nature Conservation, Building and Nuclear Safety (1998–2005), member of the Parliamentary Advisory Board on Sustainability (2005–2009) and chairman of the Committee on Transport, Building and Urban Affairs (2009–2011). He was his parliamentary group's spokesperson on environmental policy (2002–2005) and on transportation policy (2005–2009).
While still in parliament, Hermann joined Gerhard Schick, Hans-Christian Ströbele and Anton Hofreiter in their successful 2011 constitutional complaint against the refusal of Chancellor Angela Merkel’s government to provide information on Deutsche Bahn and financial market supervision. In its judgment pronounced in 2017, the Federal Constitutional Court held that the government had indeed failed to fulfil its duty to give answers in response to parliamentary queries and to sufficiently substantiating the reasons.
Return to state politics
In 2011, Hermann went back to Baden-Württemberg state politics and became State Minister for Transportation in the cabinet of Winfried Kretschmann. He held this position until 2026. As one of his state's representatives at the Bundesrat, he served on the Committee on Transport. In the 2016 state elections, he was also re-elected to the Landtag of Baden-Württemberg.
