Turning sustainability ambition into structured progress for hospitality organisations
HOLITRA is a boutique hospitality consulting firm focused on sustainability systems for hotels and tourism organisations. We work with hotel groups, operators and investors across Austria, the DACH region and wider Europe to build credible sustainability strategies, achieve recognised certifications and embed responsible practices into the core of their operations.
Our work translates sustainability ambitions into clear structures, measurable progress and credible long-term positioning. We connect strategy, operational practices, certification frameworks and reporting requirements into a coherent approach that organisations can realistically implement.
The priority is always practical implementation that works within the operational realities of hospitality organisations.

We combine expertise from several professional domains relevant to sustainability in hospitality and tourism.
This integrated perspective allows hospitality organisations to connect sustainability strategy, certification, reporting and operational implementation into one coherent and manageable framework.
