What BAUM Consult does

B.A.U.M. Consult GmbH is a German sustainability, energy, climate and mobility consultancy headquartered in Munich, founded in 1991 as a spin-off of BAUM e.V. and operating today from six locations across Germany (Berlin, Munich, Hamburg, Hamm, Stuttgart) and Austria (Graz). The firm serves a diversified client base that includes large corporates (Mars, Messe Düsseldorf, COMPO, Alpensped, Baumit), municipalities and counties (Stadt Backnang, Gemeinde Sylt, Gemeinde Breuna, Landkreis Böblingen), and federal agencies such as Umweltbundesamt and Austria's BMK, with its Japanese arm B.A.U.M. Consult Japan extending reach into Asia via a joint venture with Okuyama & Partners.

The company's core services are built around regulatory-driven advisory and operational sustainability programs. Named practice areas span climate protection concepts, mobility concepts, energy concepts, environmental management systems, sustainability/CSR strategy, climate-friendly procurement, and a wide compliance stack including CSRD reporting, BISKO, Wärmeplanungsgesetz (WPG), EEG, Energieaudit, Abwärme, KSG and GoBD. The firm has audited 240+ companies since 2015, runs the ÖKOPROFIT club with 30+ member companies, and monitors 140+ projects per year on behalf of the Austrian Climate and Energy Fund, indicating a delivery model centered on multi-year programmatic engagements rather than discrete one-off projects.

BAUM Consult operates under a partner-led professional services model with three named managing partners (Hannah Witting, Michael Wedler, Johannes Auge) and an interdisciplinary team of approximately 67 employees spanning engineering, ecology, business administration, communication and social sciences. Revenue mechanics are project- and program-based consulting fees; no pricing, ARR, or revenue figures are publicly disclosed. Recent strategic activity — the Graz office (2024), the Hamburg and Stuttgart expansions (Feb 2026), the B.A.U.M. Consult Japan JV (2019), and the launch of a "Kommunale Wärmeplanung in der Praxis" training course — points to a firm investing behind the German and European regulatory compliance wave.

Core offering

B.A.U.M. Consult is a sustainability consulting firm that delivers project-based advisory services across energy management (ISO 50001, DIN 16247 audits), climate protection (municipal heat planning per WPG, integrated climate protection concepts), sustainable mobility, sustainability reporting (CSRD/DNK), and environmental management systems (EMAS, ISO 14001/45001) for companies, municipalities, and public authorities in the DACH region and broader Europe.

Product overview

BAUM Consult operates as a traditional sustainability consulting firm offering advisory services across five core practice areas: Energy, Climate, Mobility, Sustainable Business, and Environment. The firm provides a portfolio of consulting services rather than a unified software product, with offerings including ISO 50001 energy management systems, municipal heat planning, climate protection concepts, and mobility concepts. These services are delivered through advisory engagements, training programs, and program coordination support for public funding schemes. The company serves municipalities, businesses, and public authorities primarily in German-speaking regions with practical, customized, and innovative solutions.
