Lisa Mazzone (born 25 January 1988) is a prominent Green Party politician in Switzerland. She was elected to the Swiss parliament ("Nationalrat" / "Cussegl naziunal") on 18 October 2015, becoming Switzerland's youngest member of parliament in the process. Most of her political interventions to date have involved environmental issues. Provenance Lisa Mazzone was born in Geneva, the largest city in the francophone western part of Switzerland. She grew up in nearby Versoix, where she attended school and where until 2011 Luigi Mazzone, her father, Sergio Mazzone, served as a city councillor, representing the "Geneva Ecologist Party" ("Parti écologiste de Genève"). He is also a retired installer of solar panels. Her mother died in 2013: she had worked as a psychiatrist. Three of Lisa Mazzone's four grand parents emigrated from Italy to work at the CERN ("European Organization for Nuclear Research" / "Organisation européenne pour la recherche nucléaire") which occupies a large site straddling the Franco-Swiss frontier a short distance to the north of Geneva. Along with her Swiss passport she also carries an Italian passport. Her paternal grandmother, born Beatrice Gmur, who also worked at the CERN, came originally from St. Gallen, a politically conservative canton in eastern Switzerland. Parliaments In 2006, aged 18, Mazzone took part in the establishment of the Youth Parliament ("parlement des jeunes") at Versoix. She became a member of the national committee of the Swiss Federation of Youth Parliament in 2007/08. She joined the Green Party in 2008. She served as president of the Geneva party between March 2014 and March 2016. She then became Party Vice-President for the Suisse Romande region in succession to Robert Cramer on 16 April 2016. Bicycles and transport Many of the slopes around the foreshore at the western end of Lake Geneva are reassuringly gentle: Lisa Mazzone became a passionate advocate for cycling when she was barely a teenager. She worked as a co-ordinator for the Geneva Pro-Vélo association between 2010 and 2014. In 2014 she stepped down from that job in order to become Project Manager with the association. Since April 2015 she has also been vice-president at the "National Association for Transportation and the Environment" ("Association transports et environnement"). She has subsequently become the association's president for the francophone region surrounding Geneva. Political representative Mazzone sat as a municipal councillor ("Conseil communal") in Le Grand-Saconnex - the multi-cultural central Geneva municipality which includes both the city airport
