Overview

• The Green caucus, led by Bettina Jarasch, urges a conscience vote by lifting the party whip and insists on passing the citizen draft without dilution.
• The Abgeordnetenhaus will open its Thursday sitting with a debate on the proposal, which mandates binding heat‑action plans and expands street trees and access to green space.
• After rejecting the draft in July over cost concerns, the CDU–SPD leadership says it supports the goals, has formed a working group, and is examining whether the bill can be taken over "im Wesentlichen."
• The initiative’s projected cost of about €7.2 billion through 2040 has prompted calls from coalition leaders for budget clarity before any adoption.
• With a statutory deadline of November 3 and the next feasible vote expected on October 9, organizers say they would start a December signature drive to seek roughly 170,000 backers for a possible September 20, 2026 ballot if the bill is not adopted.
