GSTC MICE Standard

v1.0 · 451 performance indicators · Venues, Event Organisers, and Events/Exhibitions

The GSTC MICE Standard v1.0 is the global benchmark for sustainable practice across the meetings, incentives, conferences, and exhibitions sector. It is the most structurally complex GSTC standard — assessing three distinct entity types independently across 451 performance indicators in four sections: venues, event organisers, and events or exhibitions, each with their own certification pathway.

Who GSTC-M applies to and how the three entity types work

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

GSTC-M is the GSTC MICE Standard. It is the global benchmark for sustainable practice in the meetings, incentives, conferences, and exhibitions sector. Unlike every other GSTC standard, GSTC-M certifies three distinct entity types — Venue, Event Organiser, and Event/Exhibition — each independently, with their own performance indicators and evidence requirements within the same standard. A convention centre, a professional conference organiser, and a major trade exhibition are all within scope, but they are assessed differently. Certification is issued by a GSTC-Accredited Certification Body after an audit of the entity's sustainability management system, operations, and documented evidence.

What are the three entity types in GSTC-M?

→Venue: A physical facility that hosts events — convention centres, conference hotels, exhibition halls, ballrooms, and dedicated event spaces. The Venue is assessed on its permanent physical infrastructure, operational systems, and the sustainability services it provides to event clients. Venue certification is ongoing and not event-specific.

→Event Organiser: A company or organisation that plans, produces, and manages events on behalf of clients or as a business — professional conference organisers (PCOs), event management companies, corporate event teams, and association management organisations. The Event Organiser is assessed on its organisational sustainability management system and how it applies sustainability principles across the events it produces. Certification covers the organiser's entire practice, not individual events.

→Event/Exhibition: A specific recurring event or exhibition assessed as a standalone entity — a named trade fair, annual conference, or regular exhibition. The Event/Exhibition is assessed on the sustainability of each occurrence of the event itself. This pathway applies when an event owner (which may be an association, corporation, or DMO) wants certification for a named event regardless of which organiser or venue is used.

Can one organisation pursue more than one entity type at the same time?

Yes — and it is common. A convention centre that also operates its own event production unit can pursue Venue and Event Organiser certification simultaneously. A trade fair association that owns both a recurring exhibition and in-house organising capacity can pursue Event/Exhibition and Event Organiser. Each entity type is audited independently against its own performance indicators, but the evidence bases overlap substantially, making dual certification significantly more efficient than two separate certification processes.

My company organises corporate incentive travel, not conferences. Does GSTC-M apply?

Yes. Incentive travel programmes — hosted buyer trips, reward experiences, group travel products organised for corporate clients — fall within the Event Organiser scope when they involve organised group events with managed logistics, accommodation, programming, and catering. The 'I' in MICE is explicitly in scope. The standard's criteria for community impact, local employment, transport, and cultural interaction are directly applicable to incentive travel.

Does GSTC-M apply to a hotel that has a meeting room?

GSTC-M's Venue pathway is designed for facilities where MICE is a material part of operations — convention centres, conference hotels, and purpose-built event spaces. A hotel with incidental meeting room capacity is more typically assessed under GSTC-H. If MICE revenue and event hosting constitute a significant portion of the hotel's operations, the relevant CB will advise on whether GSTC-M Venue certification is appropriate alongside or instead of GSTC-H.

Why should a MICE business get certified?

The commercial and operational case

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

Corporate buyer requirements

Corporate event buyers — particularly large multinationals with ESG commitments — are increasingly requiring venues and organisers to hold independently verified sustainability certification as a condition of procurement. A venue or organiser without certification is being excluded from shortlists that previously required only self-reported sustainability statements. This shift is most advanced in European and North American corporate travel programmes, and is accelerating in Singapore and the broader Asia-Pacific MICE market.

Association and government events

International associations and government procurement bodies increasingly mandate sustainability certification for event venues and organisers in their RFP requirements. ISO 20121 and GSTC-M are the two most commonly referenced standards. GSTC-M provides an internationally recognised, independently verified credential that satisfies these requirements.

EU regulatory alignment

EU Directive 2024/825 (September 2026) requires independently-verified third-party certification to substantiate sustainability claims made to EU consumers. For venues and organisers marketing to European clients and associations, GSTC-M certification is one of the recognised compliance pathways for claims about event sustainability.

Destination credentialing

Convention bureaux and destination marketing organisations promoting a city or region for MICE business increasingly use the sustainability certifications of their venues and organisers as destination differentiators. A cluster of GSTC-M certified venues strengthens a destination's positioning for sustainability-conscious international event bids.

How does GSTC-M differ from ISO 20121?

ISO 20121 is a process management system standard — it certifies that an organisation has a functioning management system for sustainable events, structured around continual improvement. GSTC-M is a performance standard — it specifies what the organisation must actually be doing and documenting across sustainability, social, cultural, and environmental dimensions, and certifies that those requirements are met. ISO 20121 certification means the process is in place; GSTC-M certification means specific sustainability outcomes are being achieved and independently verified. Some organisations hold both; the management system evidence built for ISO 20121 provides strong foundations for GSTC-M preparation.

My venue already has a green building certification. Does that count?

Building certifications — Green Mark (BCA), LEED, BREEAM — certify the physical infrastructure and its environmental performance. GSTC-M certifies the sustainability of operations, stakeholder management, community relationships, and the event experience. Green building certification provides strong evidence for a subset of GSTC-M Section D criteria (energy, water, waste), but does not cover the management system, social impact, cultural heritage, GHG emissions management, transport, or the event-specific criteria that make up the majority of GSTC-M's 451 performance indicators.

Cluster 3

What does GSTC-M cover?

Four sections, three sub-groups in Section D, and what's distinctive

What are the four sections of GSTC-M?

→Section A — Sustainable Management — 9 criteria covering sustainability policy and plan, risk management, legal compliance, reporting, staff engagement, stakeholder collaboration, destination sustainability alignment, sustainable materials, and purchasing.

→Section B — Socioeconomic Benefits — 9 criteria covering community support, local employment, community services, local livelihoods, code of conduct, exploitation and human trafficking, access for all, employment equality, and decent work.

→Section C — Cultural Heritage — 3 criteria covering cultural interactions, protecting cultural heritage, and the presentation of local culture.

→Section D — Environmental Stewardship — 11 criteria in three sub-groups: conserving resources (energy, water); reducing pollution (GHG, transport, wastewater, solid waste, harmful substances, general pollution); and conserving biodiversity (biodiversity, invasive species, wildlife interactions).

Sustainable Management

· Sustainability policy and plan
· Risk management
· Legal compliance
· Reporting and communication
· Staff engagement
· Purchasing and contracting

Criteria vary by entity type — Venue, Event Organiser, and Event/Exhibition have different performance indicators

Socioeconomic Benefits

· Community support
· Local employment
· Code of conduct
· Exploitation and trafficking
· Access for all
· Decent work

Exhibitors are a distinct stakeholder group in MICE — managed through B5 code of conduct and B6

Cultural Heritage

· Cultural interactions
· Protecting cultural heritage
· Presenting local culture
· IP rights for communities
· Indigenous community consent

Event Organiser must not include orphanage visits in event programmes (C1) — MICE-specific

Environmental Stewardship

· Energy conservation
· Water stewardship
· GHG Scope 1/2/3 emissions
· Transport and delegates
· Solid waste diversion
· Biodiversity conservation

⚠ Scope 1/2/3 GHG emissions (D2.1) — most demanding environmental requirement across all GSTC standards

What makes GSTC-M distinctively complex compared to other GSTC standards?

→Three independent entity types: 451 performance indicators are distributed across Venue, Event Organiser, and Event/Exhibition — many criteria have different performance indicators for each type, a small number apply identically to all three ("All"). No other GSTC standard requires this three-way differentiation.

→Scope 1, 2, and 3 GHG requirements: D2.1 requires measurement of emissions across all three scopes, including "areas of significant influence" in Scope 3. Delegate travel — the single largest source of event carbon footprint — sits in Scope 3. No other GSTC standard requires Scope 3 measurement, making GSTC-M the most demanding environmental standard in the GSTC suite.

→Post-event per-client reporting: A4 requires venues to produce a post-event sustainability report for each event client, containing event-specific data on waste, energy, and water. This is operationally demanding — data must be captured and reported at event level, not just annually.

→Exhibitors as a governed stakeholder group: Exhibitors are explicitly named in purchasing (A9), harmful substances (D2.5), waste (D2.4), biodiversity (D3.3), and code of conduct (B5) criteria. No other GSTC standard has a distinct stakeholder class of this kind — managing exhibitor behaviour is a unique MICE governance challenge.

→Destination site selection: A7 requires Event Organisers to have a documented process for evaluating the sustainability of event destinations during site selection. No other GSTC standard requires the entity being certified to assess the sustainability of third-party locations as part of its own practice.

How many performance indicators does GSTC-M contain, and how are they distributed?

451 performance indicators in total across 22 criteria. Section A has 9 criteria, Section B has 9, Section C has 3, Section D has 11 across three sub-groups. Sections A and B contain the largest number of entity-specific variations — the same criterion title applies to all three entity types, but the specific performance indicators differ. Section D's GHG criterion (D2.1) and Section B's code of conduct and exploitation criteria apply identically to all three types. The overall count of 451 is the sum of applicable performance indicators across all entity types.

The three entity types in practice

How Venue, Event Organiser, and Event/Exhibition are assessed differently

How does a Venue's certification differ from an Event Organiser's?

Venue

Assessed on its physical infrastructure, permanent operational systems, and services provided to event clients. Evidence is operational and ongoing: energy monitoring by meter, water systems, waste contracts, safety risk assessments for the facility, accessibility features, staff training programmes. The Venue must also provide post-event sustainability reports to clients (A4), maintain a sustainable purchasing policy for building materials and decor (A9), and pursue green building certification for any significant new construction (A8). Venue certification is not event-specific — it covers the facility's year-round sustainability practice.

Event Organiser

Assessed on its organisational sustainability management system and how it applies sustainability across all events it produces. Evidence spans the organiser's own office operations (energy, water, waste) and the events it manages (transport, purchasing, exhibitor management, community impact, GHG reduction per attendee). The Event Organiser must also have a documented destination sustainability evaluation process for site selection (A7) — assessing the sustainability credentials of venues and destinations before committing to them.

Event/Exhibition

Assessed per occurrence of a named recurring event. Evidence is event-specific — capturing what happened at each instance of the conference or exhibition. GHG emissions are calculated per occurrence and per attendee. Waste diversion is measured per event. Community support, local employment, and transport data are collected for each event. The Event/Exhibition pathway suits associations, corporations, or DMOs that own a recurring event and want the event itself certified regardless of which organiser or venue delivers it.

Which criteria apply identically to all three entity types?

Several criteria are assessed with the same performance indicators regardless of entity type — the standard labels these 'All'. They cover areas where the responsibility is the same across Venue, Event Organiser, and Event/Exhibition:

→A5 — Staff engagement: training, anonymous feedback, multilingual materials

→A6 — Stakeholder collaboration: feedback systems, corrective action

→B4 — Local livelihoods: not restricting community access to transport, residences, resources

→B5 — Code of conduct: expectations for staff, suppliers, exhibitors, and attendees

→B6 — Exploitation, harassment, and human trafficking: policy, training, supplier contracts

→B8 — Employment inclusion and equality: anti-discrimination in all roles

→B9 — Decent work: ILO compliance, safe working environment, fair wages

→C3 — Presenting culture and heritage: authentic local culture, IP rights, community consultation

→D2.1 — GHG emissions: Scope 1/2/3 measurement, IPCC-aligned targets, verified offsets

→D2.4 — Solid waste: measurement, diversion targets, guidance to stakeholders

→D3.2 — Invasive species: guidelines to stakeholders, native plants in landscaping

Our convention centre hosts events but also organises some events in-house. Do we need both Venue and Event Organiser certification?

If your in-house event production is a material part of operations — you are producing events as principal, not just providing a facility — then both entity types are relevant and dual certification is appropriate. The CB will assess your Venue operations under Venue criteria and your in-house event production under Event Organiser criteria. In practice, the management system, purchasing, and environmental monitoring evidence overlaps substantially, so dual certification is more efficient than it might appear. Consult your CB on scoping before deciding — the boundary is whether you are acting as organiser (principal) or as a facility provider (venue only).

Cluster 5

Exhibitors and supply chain

A stakeholder group unique to the MICE standard

Why are exhibitors a distinct governance challenge in GSTC-M?

Exhibitors are independent businesses operating within the controlled space of an event, bringing their own materials, displays, chemicals, food products, and staff. They are beyond the direct employment and procurement control of either the venue or the event organiser — yet their behaviour directly affects the event's waste volumes, chemical safety records, carbon footprint, and cultural sensitivity. GSTC-M explicitly addresses exhibitors as a named stakeholder group in multiple criteria. Managing exhibitor sustainability compliance is an evidence requirement, not an aspiration.

What do GSTC-M criteria require for exhibitor management?

Exhibitor-specific requirements appear across four sections:

→A9 — Purchasing: the Event Organiser must provide exhibitors with guidance on sustainable procurement, particularly of booths and displays; exhibitor contracts must include environmental sustainability requirements

→D2.4 — Solid waste: guidance on minimising waste is explicitly required to be provided to exhibitors; the waste diversion rate counts exhibitor waste

→D2.5 — Harmful substances: the Event Organiser must request safety data sheets (SDS) for any harmful substances brought on-site by exhibitors, and request that exhibitors substitute harmful substances with certified alternatives where available

→D3.3 — Wildlife interactions: the Event Organiser must ensure that exhibitors providing wildlife or products from the wild comply with local regulations and CITES requirements

→B5 — Code of conduct: the code of conduct is communicated to exhibitors, not just staff and suppliers

What is the most practical approach to exhibitor compliance evidence?

The most effective approach is contractual: sustainability requirements embedded in exhibitor participation agreements, with specific obligations on SDS submission, sustainable procurement, and code of conduct acknowledgement. Pre-event exhibitor briefing packs documenting what is required, confirmed as received. On-site spot-check records. Post-event waste data aggregated from exhibitor booth teardown. The CB looks for a system — not perfection, but documented expectations, communication, and follow-through. An organiser who has sent a sustainability guidance email to exhibitors but has no contracts, no confirmations, and no records will not satisfy these criteria.

Cluster 6

GHG emissions and transport — the defining environmental challenge

Scope 1/2/3 measurement, delegate travel, and the per-attendee metric

What does GSTC-M require for GHG emissions?

Criterion D2.1 applies to all three entity types and is the most demanding environmental requirement in any GSTC standard. Requirements:

→Measure GHG emissions across Scope 1 (direct), Scope 2 (purchased energy), and areas of significant influence in Scope 3 (indirect)

→Set specific reduction targets aligned with recent IPCC guidance

→Maintain a written plan to avoid and reduce emissions from operations and areas of influence

→Actively implement the plan

→Collaborate with suppliers to reduce their significant emissions

→Offset some or all remaining emissions after avoidance and reduction

→Prefer carbon removal offsets over avoidance offsets; offsets must be additional, permanent, and verified by a credible body

Scope 3 for an Event Organiser or Event/Exhibition includes delegate travel — by far the largest source of event carbon. Measuring and reporting delegate travel emissions requires data collection from attendees, which is operationally demanding. Begin building delegate travel data collection into registration processes before attempting certification.

What does the transport criterion (D2.2) require, beyond GHG?

D2.2 is separate from GHG measurement — it addresses active transport behaviour management:

→Venue: actively encourage staff, clients, and suppliers to use the cleanest and most resource-efficient transport available; implement strategies to minimise single-occupancy vehicle use for transfers between arrival points and the venue

→Event Organiser/Event: written policy to minimise transport requirements and prefer cleaner transport; encourage staff, exhibitors, attendees, and suppliers toward public transit and low-emission options; implement strategies to minimise single-occupancy vehicle use by attendees

Evidence: documented transport policies; pre-event communications promoting sustainable travel options; shuttle service or public transit information provided to attendees; data on transport mode uptake where collected.

What waste requirements are distinctive in GSTC-M?

D2.4 requires that the waste diversion rate (recycled and reused waste as a proportion of total) equals or exceeds the national or municipal average recycling rate for the venue/event location. This is a comparative performance benchmark — not an absolute target. For high-recycling-rate countries, this is a demanding bar. Evidence required: waste measured by stream (food, recyclables, landfill, incineration); a written solid waste management plan covering reduction, reuse, donation, and recycling; a separate battery and electronics recycling programme; guidance provided to clients, exhibitors, suppliers, attendees, and staff. Waste data at event level is required for Event/Exhibition certification.

Our events have significant food waste from catering. Is that addressed?

Yes — D2.4 explicitly requires that the solid waste management plan addresses food waste. For Events/Exhibitions and Event Organisers, this means procurement planning (right-sizing catering orders), redistribution agreements with food banks or community organisations, composting arrangements, and measurement of food waste volumes. A catering contract that doesn't address waste measurement and diversion is insufficient. Venues providing catering services must also address food waste within their D2.4 evidence.

Cluster 7

Evidence and the certification process

What each entity type produces, and how the audit works

What does a Venue's evidence portfolio look like?

→Management system — sustainability policy and multi-year plan, approved by senior management; annual review records

→Operational monitoring — energy, water, and waste metered and recorded by type with annual targets and reduction trend data

→Post-event reports — per-event sustainability data reports provided to clients (required by A4)

→Risk assessment — documented health and safety risk analysis for events; emergency management plan

→Purchasing — written sustainable purchasing policy; supplier contracts with sustainability clauses

→Staff — training records across sustainability, safety, and accessibility roles

→Accessibility — facilities audit; request and service records for additional access requirements

→Community and employment — local staff proportion data; community support records

→GHG — Scope 1 and 2 emissions inventory; reduction plan; offset documentation

→Legal — all permits, licences, and certificates current and on file

What does an Event Organiser's evidence portfolio look like beyond the Venue requirements?

→GHG — Scope 1, 2, and 3 emissions covering delegate travel; per-event per-attendee calculation; IPCC-aligned reduction targets; verified offsets

→Transport — written transport policy; pre-event sustainable travel communications to attendees; modal shift data where collected

→Destination evaluation — documented site selection process including sustainability criteria for venues and destinations (A7)

→Exhibitor management — exhibitor participation contracts with sustainability clauses; SDS requests; pre-event sustainability briefings; post-event exhibitor waste data

→Per-event reporting — post-event sustainability performance data for each event produced

→Procurement — sustainable purchasing policy applied to event materials, catering, AV, and temporary structures; exhibitor procurement guidance

→Community — local employment and supplier data per event; cultural interaction records for events involving site visits

How does the certification process work for MICE entities?

The entity self-assesses against the applicable GSTC-M performance indicators and assembles its evidence portfolio. It engages a GSTC-Accredited CB — find the list at gstcouncil.org. The CB conducts a Document Review remotely, assessing all submitted policies, records, reports, and contracts. The CB then conducts an Onsite Visit — for a Venue, this involves a facility inspection and operational review; for an Event Organiser, an office audit and records review; for an Event/Exhibition, an on-site audit during an actual event occurrence. The CB issues a certification decision. Certification is valid for three years with annual surveillance.

How long does the process take?

A Venue with mature energy/water monitoring systems, event-level reporting already in practice, and a documented management system can complete certification within four to eight months of engaging a CB. An Event Organiser without Scope 3 GHG measurement and without exhibitor management systems in place should budget twelve to eighteen months — the delegate travel data collection and exhibitor compliance infrastructure take time to build. An Event/Exhibition certification requires at least one audited occurrence, which constrains the timeline to the event's own calendar.

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

Major nonconformities must be resolved within 90 days. The most common across all three entity types:

⚠No Scope 3 GHG measurement — particularly delegate travel; absent in nearly all first-time Event Organiser applicants

⚠No post-event sustainability report provided to clients — Venue A4 requirement frequently overlooked

⚠No written solid waste management plan with food waste addressed

⚠No exhibitor sustainability requirements in participation contracts

⚠No documented destination sustainability evaluation process for site selection (Event Organiser A7)

⚠No safety data sheets (SDS) system for exhibitor chemicals (D2.5)

⚠Waste diversion rate below local municipal average with no documented improvement plan

⚠No annual sustainability policy review records

Build GHG measurement, exhibitor contracts, and post-event reporting infrastructure before Document Review — these take the longest to establish and are the most common cause of delayed certification.

Cluster 8

After certification and related standards

Validity, renewal, and the GSTC ecosystem

How long is GSTC-M certification valid?

Three years from the date of issue, with annual surveillance audits during the period. For Event/Exhibition certification, each occurrence of the event is audited as part of the annual surveillance cycle. A full recertification audit is conducted at the end of three years against the current version of GSTC-M v1.0.

Can a venue pursue both GSTC-M and GSTC-H certification?

Yes. A conference hotel that operates significant MICE facilities may pursue GSTC-H for its hotel operations and GSTC-M Venue for its event facilities. The two standards share common structure and considerable overlap in management system, community, and environmental criteria — building both evidence bases simultaneously is efficient. The CB will advise on scoping to avoid duplicate assessment and will structure the audit to cover both standards where possible.

How does GSTC-M relate to the destination's GSTC-D certification?

GSTC-D criterion A4 requires the destination to actively promote GSTC-Recognised certification schemes to businesses — and to maintain a list of certified enterprises. A MICE venue or event organiser holding GSTC-M certification is direct A4 evidence for any destination pursuing GSTC-D. Additionally, GSTC-M criterion A7 requires Event Organisers to evaluate the sustainability of destinations during site selection — a destination with GSTC-D certification has independently verified governance credentials that an organiser can use in its A7 site selection assessment. The two standards are designed to reinforce each other.

My event organiser holds ISO 20121. What does GSTC-M add?

ISO 20121 is a management system standard — it certifies that your processes for sustainable event management are structured, documented, and subject to continual improvement. GSTC-M certifies that specific sustainability outcomes are being achieved: GHG measured to Scope 3, waste diverted at or above the local average, exhibitor chemicals managed, delegate transport actively managed, community impact positive. The management system evidence from ISO 20121 maps strongly onto GSTC-M's Section A criteria and reduces preparation workload — but does not substitute for the performance evidence GSTC-M requires across Sections B, C, and D.
