His articles appeared in a wide variety of Italian newspapers, ranging from the right-wing Il Foglio and Libero to the leftist Il Riformista; he is also a regular contributor to a number of right-wing international media, including Tech Central Station, National Review, and the EU Reporter, a heavily pro-industry Brussels-based newsletter. He edited the Italian edition of Steve Milloy's book Science Without Sense, with a preface by the Italian minister of Defense, Antonio Martino.
He maintains a personal blog in Italian campaigning against the Kyoto Protocol, renewable energy, for free gun ownership and pro-smoking . He wrote the book "Waco. A State Massacre in the US" (with a preface by Russian activist Vladimir Bukosvky) and was a contributor to Kendra Okonski's recent climate sceptic book Adapt or Die. He has strong links with the Bush administration and the anti-environmental lobby in Washington, DC: for example he interviewed the Chairman of US Senate Committee on Environment & Public Works, Sen. James Inhofe , and was quoted in a Wall Street Journal anti-Kyoto op-ed by Italy's Minister of Defense Antonio Martino .

He has authored a number of articles and essays opposing the Kyoto Protocol and other climate policies.
