Bremen's climate crisis deepens as emissions targets slip out of reach
Bremen is facing a climate crisis as it struggles to meet its emissions targets. Despite years of Green Party leadership in environmental policy, the city-state remains far behind its goals. Officials now warn that an 'emergency programme' is needed to avoid failure.
The Green Party has overseen Bremen's environmental policies since 2007, yet progress has fallen short. While some advances have been made at local and state levels, the city's overall climate performance remains weak. A report by the IFEU Institute revealed that Bremen taps only 20% of its potential in energy and waste management, with renewable electricity generation at 6% and wastewater reduction at 0%.
One major obstacle is the steel plant, responsible for half of Bremen's CO₂ emissions. Though the city sometimes excludes the plant from calculations to highlight progress elsewhere, its industrial output continues to hinder climate efforts. Between 2020 and 2025, industrial emissions dropped by roughly 15%, partly due to decarbonisation projects like green hydrogen trials at thyssenkrupp Steel Europe. The city's building sector is also lagging. In 2021, only 1.35% of buildings underwent energy-efficient retrofits—far below the 3.2% target for 2030. A planned consulting programme to unlock housing potential in existing buildings has yet to launch, and the Senate has delayed drafting its renovation strategy due to staff shortages. Transport policy faces similar challenges. The citizens' initiative *Simply Mobile* has pushed for a legally binding shift away from car traffic, but no concrete measures have been adopted.
Without urgent action, Bremen will miss its climate targets. The city must accelerate building retrofits, expand renewable energy use, and address industrial emissions. Officials acknowledge that current efforts are insufficient, leaving the need for a comprehensive emergency plan clear.
