Career in state politics In 2008, Janecek achieved via a verdict through the
European Court of Justice that citizens under the impact of particulate pollution, could urge responsible authorities to reduce the pollution exceeding the legal threshold. As a consequence, Munich was forced to change its status quo and to establish a
low-emission zone. Janecek served as co-chair of the Green Party in Bavaria from 2008 until 2014, alongside
Theresa Schopper (2008–2013) and Sigi Hagl (2013–2014); at the time, he was the youngest person to ever hold that position. He is also the founder of the nonpartisan transatlantic thinktank
Die Transformateure.
Member of the German Bundestag, 2013–2025 From the federal elections of
2013, Janecek was the Green Party candidate of the Munich constituency 221 München-West/Mitte. He has always received his seat in the Bundestag through his position on the Green electoral list. In parliament, Janecek was a member of the Committee on Economic Affairs (2013–2025) as well as of the Committee on the Digital Agenda (2013–2021). He served as his parliamentary group's spokesperson on economic policy (2013–2017, 2021–2023), the digital economy (2018–present) and
industrial policy (2019–2025). Janecek also served as a member of the Study Commission of the Bundestag on "Artificial Intelligence – Social Responsibility and Economic, Social and Ecological Potential". In the negotiations to form a so-called
traffic light coalition of the
Social Democratic Party (SPD), the Green Party and the
Free Democrats (FDP) following the
2021 German elections, Janecek was part of his party's delegation in the working group on innovation and research, co-chaired by
Thomas Losse-Müller,
Katharina Fegebank and
Lydia Hüskens. ==Other activities==
