Lean & Green

What Lean & Green does

Lean & Green is a consulting methodology and service brand offered by T&O Group that integrates Lean Management principles with environmental protection and resource efficiency for corporate clients. The offering is built on a structured portfolio: the Lean & Green Check diagnostic, a value stream thinking framework with environmental considerations, strategic target derivation methods, problem-solving and continuous improvement methodologies, and a sustainability-linked performance management system. These components are designed to translate abstract sustainability goals into operational routines embeddable inside ongoing lean processes.

The business model is professional services revenue: direct consulting engagements, training programmes on Lean and Green topics, and an annual Lean & Green Management Award combined with a Lean & Green Summit best-practice event. The go-to-market is sales-led, with a free initial consultation used to qualify opportunities, supported by a multi-channel marketing presence (LinkedIn, YouTube, Facebook, Instagram, newsletter) and direct enterprise outreach. Customer acquisition is reinforced by the annual award, which functions both as a benchmark platform and a demand-generation mechanism.

Lean & Green primarily serves manufacturing and industrial companies in the DACH region, addressing pain points around weak anchoring of sustainability in internal processes, lack of transparency on process-level impact, and the gap between external sustainability marketing and internal operational reality. Only one customer is publicly identified as a flagship (Gerhard Schubert GmbH, overall winner of the 2025 Award and host of the 2026 Summit). The brand sits within a broader T&O Group portfolio that includes other consulting brands (Mobility Maintenance, GEPRO, procon, agiplan.ch, Quadriga Consult, CIM AACHEN), and operates alongside related digital/Industry 4.0 services inside the parent's Industrial Excellence line.
