3. Local Laws Overview

Below are three key laws and regulations that govern energy, environment and ESG matters in Mannheim, Karlsruhe, Stuttgart and surrounding areas. Note the effective dates where applicable and how they interact with local practices in Mannheim.

• Erneuerbare-Energien-Gesetz (EEG) - 2023 Edition. This federal law supports renewable energy deployment and defines tariffs, priority access to the grid, and market mechanisms. The EEG 2023 generally took effect on 1 January 2024, shaping project development and subsidy eligibility across Germany, including Mannheim projects.
• Gebäudeenergiegesetz (GEG) - 2020 Update. The GEG merged energy efficiency rules for buildings from prior laws and regulates insulation, heating systems and energy performance certificates. It became effective on 1 November 2020, with subsequent amendments guiding new and renovated buildings in Baden-Wuerttemberg including Mannheim developments.
• Bundes-Immissionsschutzgesetz (BImSchG) and TA Luft. The BImSchG governs emissions from industrial facilities and energy plants, while the Technical Instructions on Air Quality Control (TA Luft) set specific limits. These frameworks apply to Mannheim’s industrial sector and any new emissions sources, with ongoing updates at the federal level that affect local compliance plans.

In addition to these federal rules, developments in ESG regulation at the EU and national levels influence Mannheim practice. Large German companies and their value chains face enhanced reporting duties and due diligence requirements that translate into practical compliance programs in Baden-Wuerttemberg. For strategic ESG planning, aligning with CSRD and Lieferkettengesetz expectations is increasingly important for Mannheim-based operations.
