Cluster 1

What is GSTC?

For hotel managers encountering GSTC for the first time

What does GSTC stand for, and what does it actually do?

GSTC stands for the Global Sustainable Tourism Council. It is a non-profit organisation that establishes global baseline standards for sustainable tourism and accredits independent third-party organisations — called Certification Bodies — to conduct audits against those standards. GSTC does not certify hotels directly. It sets the rules and authorises the auditors.

If GSTC doesn't certify my hotel, who does?

Your hotel is certified by a GSTC-Accredited Certification Body (CB) — an independent third-party organisation assessed and approved by GSTC to conduct hotel sustainability audits. The CB sends trained auditors to review your documentation and visit your property. If your hotel meets the standard's requirements, the CB issues certification. GSTC plays no role in individual hotel audits.

Is GSTC certification the same as a green star rating or eco-label?

No. GSTC certification is independently verified third-party certification — an external auditor confirms that your hotel meets specific documented requirements. A hotel either meets the standard or does not. There is no tier or star level within GSTC certification. It is not self-declared and it is not a label purchased from a membership body.

Why would my hotel want GSTC certification?

EU Directive 2024/825 (September 2026) requires sustainability claims made to EU consumers to be backed by independently-verified third-party certification — GSTC-H certification is one of the recognised pathways. Global booking platforms and corporate travel programmes increasingly require verified sustainability credentials. For hotels in UNESCO sites, national parks, or environmentally sensitive destinations, GSTC certification provides documented evidence of responsible operations to regulatory bodies and destination managers.

How do I find a GSTC-Accredited Certification Body?

GSTC publishes the list of accredited CBs at gstcouncil.org. CBs vary in regional coverage, sector specialisation, pricing, and timelines. Contact two or three for initial quotes and timelines before committing. The hotel may use any GSTC-Accredited CB — there is no requirement to use a local one.

The GSTC Hotel Standard — structure and scope

What it covers and how it is organised

What is the GSTC Hotel Standard v4.01 and what does it contain?

GSTC-H v4.01 is the current global benchmark for sustainable hotel operations, published by GSTC on 30 December 2025. It contains 205 performance indicators across four sections. A hotel certified under GSTC-H v4.01 has been independently audited against these 205 requirements by a GSTC-Accredited CB.

What are the four sections of GSTC-H?

→

Section A — Sustainable Management: The sustainability management system, legal compliance, staff training, reporting, and responsible facilities management.

→

Section B — Socioeconomic Benefits: Local employment, fair procurement from local suppliers, community investment, and accessibility.

→

Section C — Cultural Heritage: Protection of tangible and intangible cultural heritage and responsible tourism activities.

→

Section D — Environmental Stewardship: Energy, water, waste, GHG emissions, hazardous substances, supply chain, and biodiversity.

What is the difference between a criterion and a performance indicator?

A criterion is a top-level requirement — for example, "The hotel has an energy conservation programme." A performance indicator is the specific, auditable element beneath it — for example, "The hotel measures and records its total energy consumption by type on an annual basis." Certification is assessed at the performance indicator level. GSTC-H v4.01 contains 205 performance indicators.

Does GSTC-H apply to small independent hotels?

Yes. The standard is designed to be scalable and applies to hotels of all sizes. Where a requirement would be disproportionate for a micro-property, proportionality is considered. The CB's auditors assess each performance indicator against the hotel's specific operations, size, and context.

Cluster 3

How does certification work?

Process, roles, and timeline

What does the full certification process look like?

Five stages. The hotel self-assesses against the standard and prepares evidence. It then selects and engages a GSTC-Accredited CB. The CB conducts a Document Review remotely — assessing submitted evidence against the 205 performance indicators. The CB then conducts an Onsite Audit — visiting the hotel to verify that documented practice reflects actual operations. The CB issues a certification decision. If certification is issued, it is valid for three years, with annual surveillance audits during that period.

How long does the process typically take?

A well-prepared hotel with documented policies, monitoring records, and trained staff can move through Document Review and Onsite Audit within three to six months of formally engaging a CB. Hotels starting without a sustainability management system should budget six to eighteen months of preparation before engaging a CB for formal assessment.

What happens during the Document Review?

The CB receives and reviews the hotel's documented evidence against the standard's requirements. Auditors assess whether documented policies, procedures, records, and evidence satisfy each performance indicator. The CB may issue requests for clarification or additional documentation. Document Review is typically completed remotely.

What happens during the Onsite Audit?

An auditor or audit team visits the hotel. They verify that what is documented reflects actual practice — by inspecting facilities, observing operations, reviewing physical records, and interviewing staff at multiple levels. A hotel that has strong documentation but inconsistent practice will be identified at this stage. Onsite Audits typically last one to three days.

Is a GSTC consultant required?

No. A hotel can engage a CB directly without a consultant. Consultants are commonly used for gap assessment, documentation development, and audit preparation — particularly for hotels going through the process for the first time. Using a consultant does not influence the CB's certification decision.

Cluster 4

The Sustainability Management System

The most foundational concept in GSTC certification

What is a Sustainability Management System (SMS)?

A Sustainability Management System is the documented framework through which a hotel manages, monitors, and continuously improves its sustainability performance. Under Section A, the SMS must include at minimum: a written sustainability policy, documented sustainability targets linked to that policy, documented actions to implement the policy, and a regular review process (at least annual) to assess progress and update targets. It is not a single document — it is a system of interconnected documents, records, and processes.

What does GSTC-H specifically require in the SMS?

Section A requires the hotel to demonstrate that its SMS:

→Addresses all four sustainability dimensions: environmental, social, cultural, and economic

→Is proportionate to the hotel's size, capacity, and activities

→Includes both a sustainability policy and measurable targets

→Is reviewed at least annually, with documented evidence of that review

→Results in updated targets or actions when monitoring shows a need for improvement

My hotel already practises sustainability informally — does informal practice count?

Partially. Certification requires documented, verifiable evidence — not demonstrated intent. A hotel that separates waste, uses energy-efficient lighting, and sources locally but has no written records, policies, or monitoring data is likely practising sustainability but cannot evidence it to a CB. The process of preparing for certification typically involves formalising existing practices: writing the policy, starting measurement systems, and building a paper trail that reflects what the hotel already does.

What is the most common reason hotels fail their first audit?

Inadequate documentation of the SMS. This includes: no written sustainability policy, targets that are not measurable or time-bound, staff who are unaware of sustainability commitments, and no records of monitoring or annual review. The gap is rarely in what the hotel does — it is almost always in what the hotel can prove.

Evidence

What counts, what doesn't, and how to build it efficiently

What counts as evidence under GSTC-H?

Evidence is any documented proof that a performance indicator is met. This includes: written documents (sustainability policy, procedures, supplier contracts), records (utility bills, waste logs, training attendance sheets, purchase invoices), photographs (facility conditions, equipment), third-party certificates (staff training certificates, supplier certifications), and reports (annual sustainability reviews, community investment summaries). Evidence must be current and relevant to the specific performance indicator it is intended to satisfy.

Can one document satisfy multiple performance indicators?

Yes. A single document — for example, a comprehensive supplier selection policy that addresses local procurement, environmental standards, and fair labour practices — may satisfy performance indicators across Sections A, B, and D simultaneously. Structuring your evidence to serve multiple performance indicators substantially reduces the total volume of documentation required.

What are the most common evidence gaps hotels discover during preparation?

→No written sustainability policy

→No utility consumption monitoring records (energy and water by type)

→No documented staff training in sustainability topics

→No supplier assessment records

→No annual sustainability review with documented outcomes

My hotel doesn't have written policies yet. Can I write them now?

Yes, but with a critical condition: a policy written for the purpose of certification with no implementation history will not satisfy the standard. GSTC-H requires that policies be operational — communicated to relevant staff, reflected in actual practice, and generating records over time. The practical minimum is to implement the policy, communicate it to staff, begin monitoring, and accumulate records before submitting to the CB for Document Review.

Cluster 6

The 12 baseline performance requirements

Critical for all hotels; essential for GSTC-I transition

What are the baseline performance requirements in GSTC-H v4.01?

GSTC-H v4.01 introduces 12 mandatory baseline performance requirements — quantified minimum thresholds distributed across four areas: Responsible Procurement, Decent Work and Human Rights, Energy Conservation, and Water Conservation. Unlike most performance indicators, which require evidence of documented systems and practices, baseline requirements demand measurable performance above a defined threshold.

What does escalating thresholds mean in practice?

At Initial certification the threshold is set at a baseline level. At First Renewal (three years later) the threshold rises — the hotel must demonstrate improvement, not merely continuation. At Second Renewal (six years from initial) the threshold rises again. GSTC-H certification is structured as a continuous improvement pathway, not a once-and-done achievement.

I'm just starting the process — where should I focus first on baseline requirements?

Begin with measurement. You cannot demonstrate compliance with a threshold you are not measuring. Before Document Review, establish monitoring systems for all four areas: procurement spend by supplier category, employment and wage data, energy consumption by type (electricity, gas, fuel), and water consumption. Even if current performance falls below a threshold, having data is far preferable to having none.

Category 1

Responsible Procurement

→Minimum spend proportion with locally-owned suppliers

→Minimum proportion of consumables from sustainable or certified sources

→Documented supplier selection criteria including sustainability standards

Category 2

Decent Work & Human Rights

→Minimum wage compliance verified and documented for all staff

→Proportion of locally-resident employees at operational and supervisory levels

→Documented employment contracts in line with local labour law

Category 3

Energy Conservation

→Total energy consumption measured annually by type

→Scope 1 and Scope 2 GHG emissions tracked and reported

→Documented energy reduction target with year-on-year progress

Category 4

Water Conservation

→Total water consumption measured annually

→Documented water reduction target with year-on-year progress

→Water-efficient fixtures or practices documented and verified

Thresholds escalate at renewal

Initial certification → First Renewal (year 3) → Second Renewal (year 6). Each cycle requires demonstrated improvement, not continuation. Specific threshold values are set with your CB at the point of assessment.

Cluster 7

During the audit — nonconformities

For hotels in the certification process

What is a nonconformity?

A nonconformity is a formal finding issued by the CB when a performance indicator is not met. It is not an automatic failure of the overall certification — it is a documented gap that must be resolved. There are two categories: Major and Minor.

What is the difference between a Major and a Minor nonconformity?

A Major nonconformity is a finding where a fundamental requirement is absent — no sustainability policy, no environmental monitoring, or a significant legal compliance failure. A Minor nonconformity is where a requirement is partially met — a policy exists but has not been communicated to all relevant staff, or monitoring records are incomplete.

How long does my hotel have to resolve a nonconformity?

Under the GSTC Accreditation Manual v5.0 (Clause 8.15), a Major nonconformity must be resolved within 90 days of the finding. A Minor nonconformity must be resolved before the next annual surveillance audit — typically within 12 months. The CB verifies resolution before issuing or continuing certification.

What happens if a Major nonconformity cannot be resolved in 90 days?

If a Major nonconformity remains unresolved after 90 days, the CB cannot issue or maintain certification. The path forward depends on the nature of the finding and the CB's procedures. The CB advises on the specific process, which must comply with GSTC's accreditation requirements.

Cluster 8

After certification

For currently certified hotels and those with lapsed certification

How long is GSTC Hotel certification valid?

Certification is issued for a three-year period from the date of issue. Annual surveillance audits are required during the certification period. At the end of three years, the hotel undergoes a full recertification audit assessed against the current version of GSTC-H.

What is a surveillance audit?

A surveillance audit is a periodic verification conducted by the CB between initial certification and recertification. It confirms that the hotel continues to meet the standard's requirements and that the SMS is operating as documented. Surveillance audits are typically shorter than the initial certification audit.

My hotel's GSTC certification has expired — what do I do?

An expired certification means the hotel no longer holds current GSTC certification and should not be represented as GSTC-certified in marketing. Contact a GSTC-Accredited CB. The CB will assess the hotel's current state against GSTC-H v4.01. There is no accelerated pathway for previously-certified hotels — recertification follows the standard process.

Can my hotel use the GSTC certification mark in marketing?

Only hotels with current, active certification are authorised to use GSTC certification marks. Using a GSTC certification claim after certification has expired is not authorised and may constitute a misleading claim under consumer protection regulations including EU Directive 2024/825.

Cluster 9

Transition from GSTC-I and comparison with other standards

For hotels certified under GSTC-I or other sustainability programmes

What is GSTC Industry Standard, and how does it differ from GSTC-H v4.01?

GSTC Industry Standard (GSTC-I) was GSTC's previous accommodation standard — it applied broadly to all accommodation types. GSTC Hotel Standard v4.01, published December 2025, replaces GSTC-I for hotels. GSTC-H is more operationally specific: it introduces 12 mandatory baseline performance requirements with quantified thresholds, makes GHG Scope 1 and Scope 2 emissions tracking mandatory, and includes additional requirements around responsible procurement, circular economy practices, and EV charging infrastructure. GSTC-I is being phased out.

My hotel is currently certified under GSTC-I — do I need to transition?

Yes. All hotels currently certified under GSTC-I must transition to GSTC Hotel Standard v4.01 by 30 December 2028. The transition occurs at the next scheduled surveillance or recertification audit — hotels do not restart the process from the beginning, but their next audit will be assessed against GSTC-H v4.01.

What are the three most important things a GSTC-I certified hotel needs to prepare for?

→

Start measuring: The 12 baseline performance requirements have quantified thresholds. Hotels meeting GSTC-I through documented systems alone may fall short — begin monitoring procurement spend, energy, water, and employment data now.

→

Establish GHG tracking: Scope 1 and Scope 2 emissions monitoring is mandatory under GSTC-H and was not required under GSTC-I. Hotels not currently tracking emissions need to establish measurement systems.

→

Review procurement documentation: Responsible sourcing criteria are more specific under GSTC-H — supplier selection records should include environmental and social criteria, not just commercial terms.

I'm certified under Green Key, EarthCheck, or ISO 14001 — does that count for GSTC?

If your current certification scheme is listed as a GSTC-Recognised programme at gstcouncil.org, certification under it is broadly equivalent to GSTC certification for most commercial and regulatory purposes. If your scheme is not on the GSTC-Recognised list, it does not substitute for GSTC-H certification, though your existing documentation will provide a strong foundation for the GSTC certification process.

Can evidence from my previous GSTC-I certification cycle be used in my GSTC-H assessment?

Yes, where performance indicators are equivalent and evidence is current. Energy bills, training logs, community records, and policy documents remain valid if recent. Records more than two to three years old may be considered outdated for performance indicators requiring ongoing monitoring. The CB assesses currency and relevance.
