Who GSTC-AT applies to

What is GSTC-AT, and what does it certify?

GSTC-AT is the GSTC Attraction Standard. It is the global benchmark for sustainability at visitor attractions — covering museums, theme parks, heritage sites, wildlife venues, zoos, aquariums, adventure activity operators, botanical gardens, cultural centres, and similar visitor-facing operations. Certification confirms that the attraction manages sustainability responsibly across its operations, visitor experience, community relationships, and environmental impact — independently verified by a GSTC-Accredited Certification Body after a formal audit. GSTC does not certify attractions directly; it accredits the auditors.

Who does GSTC-AT apply to?

Any visitor-facing attraction that receives paying or non-paying visitors for tourism, recreation, education, or cultural experience. This includes:

→Museums, science centres, and galleries

→Zoos, aquariums, and wildlife sanctuaries

→Theme and amusement parks

→Heritage sites and historical monuments

→Botanical gardens and arboretums

→Adventure activity operators — zip-lining, diving, rock climbing, rafting

→Eco-tourism sites and nature reserves

→Cultural performance venues and living heritage centres

→Wildlife rehabilitation and conservation centres

The standard applies to attractions of all sizes and all levels of built infrastructure.

Does it apply to a small independent attraction?

Yes. The standard is explicitly scalable. A small community museum and a major theme park are both in scope. Evidence expected from a micro-operation differs in scale and complexity from what is expected of a large venue — but the requirement to demonstrate sustainable practice applies regardless of size. Where a specific requirement would be genuinely disproportionate, the CB assesses whether the spirit of the criterion is being met through alternative means proportionate to the attraction's scale and context.

Does it apply to an outdoor heritage site with no significant built infrastructure?

Yes. The standard covers outdoor sites, intangible heritage attractions, and operations with minimal built infrastructure. For attractions without significant physical facilities, Section D environmental criteria are assessed through operational practices — waste management in the field, transport, visitor behaviour management — rather than building operations. A walking heritage trail and a large indoor museum both fall within GSTC-AT scope.

Our hotel has a wildlife sanctuary open to visitors. Does that fall under GSTC-AT or GSTC-H?

It depends on how the sanctuary operates. If it is a distinct visitor-facing operation with its own programming, admission, and visitor management, it may be separately certifiable under GSTC-AT alongside the hotel's GSTC-H certification. If it is an amenity of the hotel without separate visitor management, it may fall within the GSTC-H assessment scope. Consult your CB to determine the appropriate standard and scoping. A hotel and its attraction can seek certification under different standards concurrently.

Why should I get certified?

The commercial and operational case

What are the concrete business benefits of GSTC-AT certification?

Market access

Destination management organisations, national park authorities, and conservation bodies increasingly require sustainability certification as a condition of operator access and partnership. International tour operators sourcing verified sustainable experiences require documented credentials from the attractions they include in their products. EU Directive 2024/825 (September 2026) requires independently-verified third-party certification to support sustainability claims to EU consumers — GSTC-AT is one of the recognised pathways.

Reputation and trust

For attractions working with wildlife, cultural heritage, or indigenous communities, independently-verified certification provides documented proof of responsible practice to stakeholders who scrutinise these areas closely — conservation bodies, animal welfare organisations, indigenous rights groups, and media. A self-declared “wildlife-friendly” label carries no weight with these audiences; GSTC-AT certification does.

Operations

The preparation process systematically surfaces animal welfare documentation gaps, visitor capacity risks, cultural heritage IP issues, and community relationship weaknesses that, once addressed, reduce operational and reputational risk.

My attraction already has strong sustainability practices. Why formalise them?

Because undocumented practice is not verifiable. An attraction with genuinely excellent animal welfare, responsible heritage interpretation, and strong community relationships that cannot document those practices has no credible evidence for tour operators, DMOs, or regulatory bodies that ask. The certification process converts practised sustainability into independently-verified proof — and reliably surfaces gaps that weren't visible before.

What does EU Directive 2024/825 mean for an attraction?

From September 2026, sustainability claims made to EU consumers — 'eco-friendly', 'responsible', 'wildlife-friendly', 'sustainable' — must be substantiated by independently-verified third-party certification. This applies to your website, OTA listings, social media, and any marketing reaching EU visitors. Attractions that rely heavily on EU inbound markets should be preparing for this now. GSTC-AT certification is one of the recognised compliance pathways.

My visitors haven't asked for sustainability certification yet. Should I still pursue it?

The window in which certification is a differentiator — rather than a baseline expectation — is closing faster in some markets than others. DMOs managing sensitive sites are beginning to require it as a condition of inclusion. Conservation bodies funding wildlife attractions increasingly ask for it. Beginning now means your animal welfare documentation, visitor management system, and evidence are built before demand requires it — not assembled under time pressure.

Cluster 3

What does GSTC-AT cover?

Structure, scope, and what's distinctive

What are the four sections of GSTC-AT?

→Section A — Sustainable Management — Sustainability management system, legal compliance, safety management for visitors and staff, staff training, guest experience management, and accurate representation to visitors.

→Section B — Socioeconomic Benefits — Local employment, fair wages, career development, community engagement, local procurement, and accessibility for visitors with diverse needs.

→Section C — Cultural Heritage — Respectful interpretation of cultural heritage and indigenous knowledge, community consent for cultural programming and exhibits, IP rights for cultural elements, and accuracy of cultural representation.

→Section D — Environmental Stewardship — Energy, water, waste, GHG emissions, hazardous substances, supply chain, biodiversity, and — for attractions with living animals — dedicated animal welfare criteria.

Sustainable Management

· Policy and targets
· Annual review
· Legal compliance
· Safety management
· Staff training
· Guest experience

Safety management is a specific assessed area unique to attractions

Socioeconomic Benefits

· Local employment and fair wages
· Community engagement
· Local procurement
· Community investment
· Accessibility

Cultural Heritage

· IP rights for cultural elements
· Community consent
· Accurate interpretation
· Guide training
· Cultural site protection

Explicit IP and consent requirements for indigenous or community cultural knowledge

Environmental Stewardship

· Energy and water conservation
· Waste management
· GHG emissions
· Biodiversity
· Animal welfare (living collections)

⚠ Animal welfare criteria — most scrutinised area in GSTC-AT audits

What makes GSTC-AT distinctive compared to other sustainability standards?

Three things set it apart. First, dedicated animal welfare criteria in Section D apply to any attraction holding live animals — this is the most operationally complex and intensively scrutinised area of the standard. Second, visitor management and carrying capacity are structured evidence requirements — not advisory guidance — meaning attractions must demonstrate active, documented management of visitor numbers relative to assessed site capacity. Third, Section C specifically addresses the use of indigenous or community cultural knowledge in exhibits and programming, with explicit requirements around IP rights and community consent that go beyond general cultural sensitivity.

How many performance indicators does GSTC-AT contain?

229 performance indicators across four sections. Each is independently audited. Certification requires all applicable performance indicators to be satisfied — there is no minimum pass rate on individual sections.

Does the standard apply differently to different types of attractions?

The same 229 performance indicators apply to all attractions, but relative emphasis shifts significantly by type. For a zoo or wildlife sanctuary, Section D animal welfare criteria are the dominant challenge. For a cultural heritage site using indigenous knowledge, Section C IP and consent criteria carry the greatest weight. For an adventure activity operator, Section A safety management receives close CB attention. For a theme park, visitor management, waste, and energy criteria are primary. The CB assesses each attraction against its specific operational context.

Cluster 4

Animal welfare — the most distinctive requirement

Applies to any attraction holding live animals in its care

What are the animal welfare requirements in GSTC-AT?

GSTC-AT requires that any attraction holding live animals — zoos, aquariums, wildlife sanctuaries, rehabilitation centres, farm attractions, petting zoos, aviaries, or any operation where animals are kept on-site — manage those animals to high, documented welfare standards. Requirements include: management protocols assessed against internationally recognised frameworks, specifically the Five Domains of Animal Welfare; continuous monitoring of animal health and wellbeing; species-specific care protocols; and restrictions on using animals in visitor activities in ways that compromise their welfare.

What is the Five Domains of Animal Welfare framework?

The Five Domains is an internationally recognised framework for systematic assessment of animal wellbeing. GSTC-AT expects attractions to demonstrate that all five are actively managed, documented, and monitored.

NutritionAdequate, appropriate food and water for the species

Physical environmentAppropriate living conditions — space, temperature, substrate, shelter

HealthDisease prevention, veterinary care, and prompt treatment of injury or illness

BehaviourOpportunity to express natural behaviours appropriate to the species

Mental stateAbsence of prolonged negative states — fear, frustration, boredom, or distress

My attraction offers animal encounter or educational demonstration programmes. What does GSTC-AT require?

GSTC-AT requires that any visitor interaction with animals be managed in accordance with science-based guidelines that prioritise animal welfare over visitor experience. Activities that cause stress or behavioural disruption — animal shows for entertainment, staged feeding demonstrations, guest handling of wild animals — are specifically flagged. The standard does not prohibit all animal interaction, but any interaction must be documented as compliant with animal welfare frameworks. Educational programmes designed with animal welfare as the primary consideration can be structured to meet the standard.

What evidence is required for animal welfare criteria?

→Documented species-specific welfare protocols covering all Five Domains

→Daily health observation records and veterinary care logs

→Welfare assessment records aligned with the Five Domains framework

→Third-party accreditations where held — WAZA, AZA, BIAZA, or national equivalents

→Documented protocols for visitor interaction management

→Evidence that animals are not used for performances that compromise welfare

→Staff training records in animal welfare appropriate to their roles and species

Animal welfare documentation is consistently the area CBs examine most closely in GSTC-AT assessments. Absent welfare protocols are a Major nonconformity regardless of actual welfare standards at the attraction — begin building documentation before anything else.

Cluster 5

Visitor management and safety

Structured evidence requirements, not advisory guidance

What does GSTC-AT require for visitor management?

GSTC-AT requires that attractions actively monitor and manage visitor numbers relative to the assessed capacity of the site. This is a documented evidence requirement — not an aspiration. The attraction must have an assessed carrying capacity, records showing visitor numbers are tracked against that capacity, and documented processes for managing situations where visitor numbers approach or exceed it. For sensitive natural or cultural areas within the site, visitor flow and impact management evidence is required.

What is carrying capacity assessment and how do I document it?

Carrying capacity is the maximum number of visitors a site can accommodate at one time while maintaining acceptable conditions for both visitors and the site's natural or cultural resources. GSTC-AT does not mandate a specific methodology — the approach should be proportionate to the attraction's scale and sensitivity. For a small cultural centre, a documented capacity limit with daily visitor count records may be sufficient. For a large outdoor site with sensitive ecosystems, a more detailed environmental impact assessment is expected. The key requirement is that carrying capacity is assessed, documented, and actively managed — not just posted as a sign and ignored.

My attraction offers adventure activities — zip-lining, diving, climbing. What safety criteria apply?

Section A includes safety management as a specific evidence area covering both visitor and staff safety. Evidence includes: documented risk assessments for all visitor activities, safety procedures and emergency protocols, records of staff safety training and activity-specific certifications, equipment maintenance and inspection logs, incident reporting records, and evidence that safety information is communicated to visitors before participation. For activities with regulatory licensing requirements — commercial diving, white-water rafting, paragliding — licence and permit compliance documentation is required.

What does GSTC-AT require for visitor communication and marketing accuracy?

Visitors must receive accurate, honest information about the attraction's sustainability commitments and — at sensitive sites — specific responsible behaviour guidelines. Sustainability claims in marketing materials must be documentably accurate. Exaggerated or misleading claims about wildlife, environmental practice, or cultural heritage in promotional materials or OTA descriptions are directly addressed in Section A. What is communicated publicly must match what can be evidenced.

Cluster 6

Cultural heritage and interpretation

IP rights, community consent, and accurate representation

What does Section C require for an attraction?

→IP rights: if the attraction uses cultural or historical elements — artefacts, symbols, stories, traditional knowledge, indigenous designs — in its exhibits, programming, or branding, it must respect IP rights and obtain necessary permissions from rights-holders

→Accuracy and consent: where the attraction presents cultural heritage or indigenous knowledge, it must do so with documented accuracy and community sanction — verified through collaboration with relevant community members, cultural experts, or heritage authorities

→Legal compliance: any cultural artefacts or historical items used in the attraction must be presented in compliance with relevant local and international laws governing their use

My attraction is built around indigenous cultural heritage. What specific obligations apply?

The standard requires documented evidence of community consent for the use of indigenous cultural knowledge, stories, practices, or materials; ongoing collaboration with relevant indigenous community representatives or cultural experts to ensure accurate, respectful, and community-sanctioned interpretation; and IP rights compliance for any cultural elements used commercially. An attraction that has been operating for years 'with community support' that is undocumented will need to formalise those relationships. Informal goodwill is insufficient evidence — the CB will look for documented engagement, consent, and collaboration.

How are guide and interpreter practices assessed?

Guides and interpreters are assessed on whether they have been trained to interpret the site's heritage accurately, respectfully, and in a way sanctioned by relevant communities or heritage authorities. Evidence: guide training records specific to the cultural or natural heritage of the site; documented interpretation guidelines reviewed with cultural experts; and evidence that guide performance is monitored. Attractions where guides improvise interpretation of sacred or sensitive cultural content without documented training and community review will face Section C findings.

My attraction's exhibits include historical artefacts. What does the standard require?

Artefacts must be used and presented in compliance with relevant local and international laws — including provenance documentation and any applicable repatriation or cultural property agreements. Section C also requires that exhibits present cultural heritage with documented accuracy. Where interpretation guides or signage describe the cultural or historical significance of artefacts, that interpretation should be reviewed with recognised cultural experts or heritage authorities, not sourced from internal assumptions about historical meaning.

Evidence and the certification process

What to produce and how to get certified

What types of evidence does an attraction produce?

→Management system documents — sustainability policy, targets, annual review report

→Safety management documentation — risk assessments, incident records, staff training certificates, equipment inspection logs, visitor activity safety briefing records

→Animal welfare records (if applicable) — welfare protocols, daily health observation logs, veterinary care records, welfare assessments, staff training records

→Visitor management records — carrying capacity assessment, visitor count records, crowd management protocols

→Cultural heritage documentation — IP permissions, community consent records, guide training records, interpretation guidelines

→Legal and licence compliance — operating permits, safety licences, environmental permits

→Energy, water, and waste monitoring records with reduction targets

→Community and employment records — local procurement, community engagement, accessibility measures

What is the minimum evidence set to begin?

Written sustainability policy covering all four dimensions. Legal compliance documentation — operating permits, safety licences, and any relevant environmental permits. Safety management documentation for all visitor activities. For attractions with living animals: documented animal welfare protocols covering all Five Domains — this must be in place before assessment proceeds. Records of at least one annual sustainability review. Without these, a CB cannot begin a meaningful Document Review.

How does the certification process work?

Self-assess against GSTC-AT's 229 performance indicators and build your evidence. Choose and engage a GSTC-Accredited Certification Body — find the list at gstcouncil.org. The CB conducts a Document Review remotely. The CB then conducts an Onsite Visit — inspecting facilities, observing operations, reviewing physical records, and interviewing staff. For attractions with living animals, the onsite visit includes direct observation of animal welfare conditions. The CB issues a certification decision. Certification is valid for three years, with annual surveillance audits.

How long does the process take?

A well-prepared attraction — with safety documentation, environmental monitoring, visitor management records, and animal welfare protocols already in place — can complete the process within three to six months of engaging a CB. Attractions starting from scratch, particularly those with living animals and no documented welfare system, should budget six to eighteen months. Animal welfare documentation is consistently the longest lead-time item for wildlife attractions.

What are the most common Major nonconformities for GSTC-AT?

A nonconformity is a CB finding that a performance indicator is not met. Major nonconformities must be resolved within 90 days; Minor within 12 months. The most common for GSTC-AT first-time applicants:

⚠No documented animal welfare management system — absent welfare protocols for living collections are a Major nonconformity regardless of actual welfare standards

⚠No written sustainability policy

⚠Visitor numbers not monitored against assessed site capacity

⚠No documented cultural heritage IP permissions or community consent

⚠No safety risk assessments for visitor activities

⚠No documented interpretation guidelines for guides at cultural or natural heritage sites

All of these should be in place before Document Review begins — not addressed after a finding is issued.

Cluster 8

After certification and other certifications

Validity, renewal, and existing credentials

How long is GSTC-AT certification valid?

Three years from the date of issue. Annual surveillance audits are required during the three-year period. A full recertification audit is conducted at the end of three years against the current version of GSTC-AT.

I hold Green Globe, Green Key, or another sustainability label. Does that count?

GSTC maintains a list of GSTC-Recognised programmes at gstcouncil.org. If your existing certification is under a programme with current GSTC recognition, it carries broadly equivalent status. Most sector-specific labels and local green tourism schemes are not GSTC-Recognised for the attraction segment specifically — verify current recognition status before assuming equivalence. Your existing documentation provides useful evidence for GSTC-AT performance indicators and reduces preparation work regardless.

My attraction holds WAZA, AZA, or BIAZA accreditation. Does that help?

Yes, significantly. WAZA, AZA, and BIAZA accreditation are evidence of high animal welfare standards and are directly referenced in GSTC-AT's animal welfare criteria. Your accreditation documentation and assessment reports serve as evidence for Section D animal welfare performance indicators. They do not substitute for a full GSTC-AT assessment across all four sections, but they substantially reduce the evidence-building workload for the animal welfare cluster — the heaviest cluster for wildlife attractions.

My attraction's certification has lapsed. What is the path back?

Contact a GSTC-Accredited CB. Existing documentation from before the lapse — welfare records, safety documentation, environmental monitoring — is useful where still current. Address gaps, update the sustainability policy and targets, and reestablish active monitoring and community engagement records. Recertification follows the full process. There is no accelerated pathway for previously-certified attractions.
