Analysen und Empfehlungen zur Vereinbarkeit von bezahlbarem Wohnen und Klimaschutz

The document titled "Analysen und Empfehlungen zur Vereinbarkeit von bezahlbarem Wohnen und Klimaschutz" is published by the Bundesinstitut für Bau-, Stadt- und Raumforschung (BBSR). Authored by a team including Dr. Katja Schumacher and Dr. Johanna Cludius, among others, it addresses the interplay between affordable housing and climate protection in Germany, highlighting the need for comprehensive strategies to meet climate targets while ensuring housing affordability.

Germany has committed to achieving climate neutrality by 2045, which necessitates significant reductions in CO2 emissions across all sectors, including the building sector. The document emphasizes that past efforts in this sector have fallen short of climate targets, making it crucial to enhance energy efficiency and transition to renewable energy sources in buildings.

The energetic modernization of buildings can impact housing costs, with potential increases due to modernization efforts. Rising energy prices have exacerbated affordability challenges, particularly for low- and medium-income households. As construction costs and inflation rates rise, the document argues for a focused approach to ensure that climate protection does not render housing unaffordable.

The study recommends several measures, including reducing the modernization allocation to alleviate tenant burdens and redesigning the housing benefit system to reflect building conditions more accurately. It suggests a social climate fund to redistribute CO2 pricing revenues, aiding vulnerable households while discouraging blanket payments that do not consider income disparities.

Achieving climate protection goals involves activating various stakeholders: homeowners, landlords, tenants, and public entities. The report identifies the differing economic realities and motivations among these groups and the necessity of tailored support and regulatory frameworks to facilitate effective climate measures in the housing sector.

Clear communication and transparency are highlighted as essential for gaining acceptance of climate measures. The document stresses that successful implementation relies on perceived fairness and the provision of tangible benefits to tenants, reinforcing the relationship between landlords and tenants through open dialogue.

A robust data infrastructure is deemed essential for tracking the effectiveness of climate policies and their socio-economic impacts. The document calls for comprehensive data collection on building energy efficiency to inform policy adjustments and ensure effective climate actions.

The study delivers a scientifically grounded contribution to the discussion on balancing affordable housing with climate protection. It outlines actionable recommendations aimed at ensuring that the transition to sustainable housing does not adversely affect low- and medium-income households, reinforcing the need for a targeted approach that encompasses economic, social, and environmental factors.
