What Sustainable does

Sustainable AG is a Munich-headquartered management consultancy founded in 2008 that specializes in sustainability, climate, and ESG advisory services for enterprise clients across the DACH region (Germany, Austria, Switzerland). The firm employs over 100 sustainability specialists led by founder and CEO Jan Marten Krebs, and operates from its headquarters at Blumenstraße 28, 80331 München under the Sustainable Group brand.

The company's offering is organized around six core service lines — Transparency, Strategy Development, Transformation, Sustainability Implementation, Impact Communication, and Compliance Assurance — covering the full lifecycle from climate accounting and SBTi target validation through to regulatory compliance (CSRD, CSDDD, EU-Taxonomy) and stakeholder reporting. A separate Sustainable Akademie delivers webinars and training programs. The firm holds technology and consulting partnerships with organizations including osapiens, envoria, ESG Playbook, adelphi, Siemens, and the UN Global Compact, enabling integrated software-enabled advisory and certification support, but does not itself operate a proprietary technology platform.

Sustainable generates revenue through project-based, quote-based consulting engagements sold via direct enterprise sales to corporate clients. Its named reference clients span at least ten industries, including EOS GmbH, Zeiss, Tchibo, Stadtsparkasse München, DMK Group, FRÄNKISCHE Group, Optima, Seeberger, Stromnetz Berlin, Maschinenfabrik Reinhausen, and Zollern. The firm has been recognized three consecutive times with the Hidden Champions Award, named in BrandEins Best Consultants 2026, certified as a Great Place to Work, and listed as a Top Consultant for 2024/2025. Sustainable is privately held with no disclosed external funding, no parent company, and operates as an Aktiengesellschaft (AG) under German corporate law.

Direct peers

• South Pole Group: Global climate solutions and sustainability advisory firm helping companies set science-based targets, decarbonize, and meet ESG reporting obligations. Highly comparable to Sustainable AG on SBTi validation, climate strategy, and corporate transformation mandates, though larger and globally distributed.
• Carbon Trust: UK-headquartered sustainability consultancy advising corporates and governments on carbon measurement, target setting, and climate strategy. Overlaps with Sustainable on SBTi-aligned advisory, carbon accounting, and regulatory readiness, though UK-rooted and slightly broader scope.
• EcoAct: International sustainability consultancy and advisory firm specializing in carbon footprinting, net-zero strategy, and CSRD/ESG advisory. Directly comparable to Sustainable on climate accounting, decarbonization roadmaps, and corporate transformation engagements across European clients.
• denkstatt: Vienna-based sustainability and environmental consulting firm part of the euqila group, advising corporate clients on ESG strategy, climate reporting, and supply chain sustainability. Closely comparable to Sustainable's DACH regional practice and explicitly named in their partner ecosystem.
• Quantis: International sustainability consultancy guiding companies on climate strategy, footprinting, and science-based target setting. Comparable services portfolio to Sustainable across strategy, measurement, and transformation, with broader geographic reach.
• GUTcert (GUT Certifizierungsgesellschaft): German certification and verification body for environmental and sustainability management systems, named as an implementation partner in Sustainable's ecosystem. Overlaps with Sustainable on sustainability compliance, ISO 14001/EMAS advisory, and assurance-adjacent work for DACH corporates.
• adelphi: Berlin-based independent think tank and consultancy on climate, environment, and sustainable development, listed as a strategic partner in Sustainable's ecosystem. Comparable on policy-grade sustainability advisory and corporate sustainability transformation engagements.

Broad incumbents

• Sphera: ESG and operational risk software-plus-advisory provider offering sustainability reporting, carbon management, and supply chain compliance solutions. Competes with Sustainable on the same corporate buyer through technology-enabled services rather than pure consulting.
• KPMG ESG Advisory (DACH): Big 4 sustainability advisory practice with deep DACH presence covering CSRD assurance, climate risk, and ESG strategy. Competes with Sustainable on the same enterprise mandates at the upper end, with materially larger bench and cross-border delivery capability.

Emerging players

• osapiens: Mannheim-based ESG software platform for sustainability reporting and compliance, listed as a technology partner in Sustainable's ecosystem. Partial competitor and partial channel partner: its tooling could automate portions of Sustainable's manual advisory work, but the firm currently wraps consulting around osapiens deployments.
