Pekka Haavisto

When Haavisto became Finland's environment minister in 1995, he was the first Green to sit in a European national cabinet. He later ran the UN Environment Programme's post-conflict assessments, which measured environmental damage from wars in the Balkans and Afghanistan, and as foreign minister from 2019 he handled Finland's NATO application, a striking role for a Green. He was runner-up in Finland's 2024 presidential election.
