Hospitality sustainability resources — the glossary and insights behind HOLITRA’s Hospitality Sustainability System.

Hospitality sustainability resources, in one place

The Knowledge Hub brings together HOLITRA’s hospitality sustainability resources: a glossary of standards-grounded definitions and an ongoing series of insights on strategy, certification, reporting and operational implementation.

Both are organized around the same six pillars as the HOLITRA Hospitality Sustainability System, so you can go from a single definition to the fuller picture of how it connects to strategy, standards, buildings, operations, reporting and continuous improvement.

FAQ – Knowledge Hub

HOLITRA’s hospitality sustainability glossary covers 68 terms spanning all six pillars of the Hospitality Sustainability System — from certifications and labels (GSTC, EU Ecolabel, Green Key, LEED, ISO 14001) to ESG and reporting terminology (CSRD, Scope 1/2/3, materiality) to building performance and day-to-day operations.

HOLITRA’s hospitality sustainability glossary includes terms across all six pillars, not just certifications. The Operations pillar covers terms for energy, water, waste and procurement; the Reporting pillar covers ESG, CSRD and disclosure terminology — the same breadth as the HOLITRA Hospitality Sustainability System itself.

The HOLITRA blog (Insights) covers hospitality sustainability strategy, certification and reporting topics in article form, while the glossary is a fixed reference: short, precise definitions of the individual terms, standards and frameworks used across the field.

HOLITRA’s hospitality sustainability definitions are grounded in recognised frameworks referenced throughout its advisory work, including GSTC, ISO 14001, EU Ecolabel, Green Key, LEED, WELL, BREEAM, DGNB and GRI, among others — not generic or self-defined terminology.

HOLITRA’s Knowledge Hub is updated on an ongoing basis: the blog publishes new articles regularly, and the glossary is reviewed and extended as hospitality sustainability terminology and standards evolve.
