Overview

• The draft "Baum-Gesetz" passed the Senate’s legal review, clearing the path for a parliamentary vote.
• The Senate must formalize its position by the end of July, after which the Abgeordnetenhaus has four months to approve the law or allow a public petition to proceed.
• The initiative targets an initial addition of 300,000 street trees and aims to reach one million new trees citywide by 2040.
• It mandates green cooling islands every 150 meters, one-hectare parks every 500 meters, plus the creation of 1,000 mini-parks and 100 extra green sites.
• Full rollout is estimated to cost €7.2–7.5 billion through 2040 and will be overseen by a new Climate Adaptation Council.
