Overview
- The Senate’s Zwischenbericht 2025 shows emissions down 42.9% from 1990 as of 2023, with the latest interim figures 6.4% lower than in the previous report and official annual savings only confirmed after a two‑year lag.
- Hamburg targets a 70% reduction by 2030, and the report projects households, industry, and commerce/services are on track, while transport requires additional measures.
- Sector results since 1990 include cuts of 48.7% in industry, 45.7% in commerce/services, 39.1% in households, and 37.8% in transport.
- Mayor Peter Tschentscher says implementation is on a good path overall despite population and economic growth, though progress varies by sector.
- Environment Senator Katharina Fegebank cites the October referendum advancing climate neutrality to 2040 as momentum for faster action, as opposition parties press concerns over heat pump rollout and building renovation pace.
