Jürgen Trittin, a former federal minister, works as a speaker and author. After studying social sciences in Göttingen, he worked as a press secretary and freelance journalist.

Before leaving the German Bundestag in 2024, he served the Green Party in various capacities for forty years. He represented the party in the Lower Saxony State Parliament from 1985 to 1990. From 1990 to 1994, he served as Lower Saxony’s Minister for Federal and European Affairs. From 1994 to 1998, he was the federal chairman of Alliance 90/The Greens.

During his tenure as Federal Minister for the Environment from 1998 to 2005, he laid the groundwork for the energy transition through the phase-out of nuclear energy, the Renewable Energy Act, and the introduction of emissions trading. Twice—in 2009 and 2013—he led his party as the top candidate and parliamentary group leader in federal elections. As a member of the Bundestag, he served on the Foreign Affairs Committee and was a co-founder of the fund to finance the phase-out of nuclear energy.

He has been a member of the ICEM Strategic and Scientific Advisory Board since 2019.
