In the late 1980s, Poletti began to work with magazines and local radio stations in the province of Belluno, and for the journal Il Gazzettino.

[citation needed] In the autumn of 2004, he arrived on the national circuit with 7 Gold and the program Aria Pulita, where he manages to put together a real popular uprising to block a bipartisan proposal for the extension of electoral reimbursements also to elections.

In February 2006, Roberto Poletti accepts the nomination for election to the Federazione dei Verdi and he became a member following the resignation of Carlo Monguzzi.

On 3 February 2008, he announced on live TV that he will leave the Chamber of Deputies publicly declaring to be ashamed of earning a salary so generous without being able to do anything in Parliament.

From 2008 he holds a regular column in the newspaper every day on Libero, and he returned to TV working again for the political programs on Antenna 3 and Telelombardia.
