Sustainability Standards for Major Events: What Organisers Need to Know

What Are Sustainable Events?

Sustainable events are designed to minimise environmental impact, support social responsibility, and deliver measurable long-term value for organisers, attendees, and communities.

A sustainable event considers every stage of the event lifecycle, from planning and procurement to delivery and post-event reporting. This includes reducing waste, lowering emissions, and aligning with broader ESG (Environmental, Social, Governance) objectives.

At a venue like the Gold Coast Convention and Exhibition Centre, sustainability is embedded into operations, from infrastructure to catering and waste management.

For organisers, sustainability is no longer optional. It is increasingly expected by stakeholders, sponsors, and attendees, particularly across corporate, government, and association events.

Key Sustainability Standards and Frameworks

Aligning with recognised sustainability frameworks ensures credibility, compliance, and measurable outcomes.

ISO Standards for Events

One of the most widely recognised frameworks is ISO 20121, the international standard for sustainable event management.

This framework helps organisers:

• Identify and manage environmental impacts
• Integrate sustainability into event planning processes
• Improve resource efficiency
• Demonstrate accountability to stakeholders

Why it matters:
Using ISO-aligned practices provides a structured, globally recognised approach to event sustainability standards.

ESG Considerations

Sustainability is increasingly assessed through an ESG lens.

Environmental:

• Carbon footprint reduction
• Energy and water efficiency
• Waste management

Social:

• Accessibility and inclusivity
• Community engagement
• Ethical sourcing

Governance:

• Transparent reporting
• Supplier accountability
• Compliance with regulations

For large-scale events, aligning with ESG principles is critical for meeting organisational and stakeholder expectations.

Practical Ways to Make Events More Sustainable

Sustainable event planning is achieved through practical, measurable actions across waste, energy, and procurement.

Waste Reduction Strategies

Reducing waste is one of the most impactful steps in environmentally conscious event planning.

Key strategies include:

• Eliminating single-use plastics
• Using digital materials instead of printed collateral
• Implementing recycling and composting systems
• Designing reusable signage and assets

Example:
Switching to digital event apps can significantly reduce paper waste while improving attendee experience.

Energy Efficiency

Energy use is a major contributor to event-related emissions.

Best practices:

• Choose venues with energy-efficient infrastructure
• Use LED lighting and efficient AV systems
• Optimise heating and cooling systems
• Schedule events to maximise natural lighting where possible

Venues like GCCEC are designed to support efficient operations at scale, helping reduce overall energy consumption.

Sustainable Catering

Catering plays a significant role in event sustainability.

Consider:

• Sourcing local and seasonal ingredients
• Offering plant-based menu options
• Reducing food waste through accurate forecasting
• Donating surplus food where possible

Impact:
Sustainable catering not only reduces environmental impact but also aligns with attendee expectations around responsible consumption.

Sustainable Event Planning Checklist

A structured checklist helps ensure sustainability is embedded across every stage of your event.

Planning phase:

• Define sustainability goals and KPIs
• Select a sustainable venue
• Engage suppliers with strong ESG credentials
• Choose digital over print materials

Delivery phase:

• Implement waste sorting systems
• Monitor energy and water usage
• Encourage sustainable transport options for attendees

Post-event:

• Measure environmental impact
• Report on sustainability outcomes
• Identify opportunities for improvement

Measuring and Reporting Sustainability

Measurement is essential to validate sustainability efforts and demonstrate impact.

Key metrics to track include:

• Total waste generated and diverted from landfill
• Energy consumption
• Carbon emissions
• Water usage
• Supplier sustainability performance

Example use case:
An organiser tracks waste diversion rates and achieves a 75% reduction in landfill waste compared to previous events.

Reporting these outcomes:

• Strengthens stakeholder confidence
• Supports ESG reporting requirements
• Provides insights for continuous improvement

Benefits of Sustainable Event Planning

Sustainable events deliver both environmental and commercial value.

Key benefits include:

• Reduced environmental impact through lower emissions and waste
• Enhanced brand reputation as a responsible organiser
• Increased attendee satisfaction
• Alignment with corporate ESG goals
• Potential cost savings through resource efficiency

For organisations prioritising ESG, sustainable events are a key component of broader business strategy.
