The Future of Events: Why Sustainability Is No Longer Optional..

As the global events industry continues to evolve, sustainability has emerged not just as a trend, but as a critical pillar of future success. From climate-conscious attendees to cost-efficient operations, event organisers are under growing pressure to rethink the environmental and social impact of their work. Here’s why sustainability matters more than ever and how event professionals can build more responsible, impactful experiences.

Sustainability by the Numbers

- 62% of event organisers plan to prioritise sustainability by 2025.

- 54% already consider it a top priority, and 47% have action plans in place.

- 90% of attendees say sustainability influences their participation.

- Sustainable events report 20% higher attendance and 25% better ROI.

- The global events industry is expected to grow from $1.23 trillion (2024) to $1.35 trillion (2025).

Why Sustainability Matters for Events

Beyond compliance and good PR, sustainable events are proving to be more efficient, engaging, and resilient. Hybrid formats reduce emissions, energy-efficient venues lower operating costs, and transparent practices attract eco-conscious sponsors and partners. Standards like ISO 20121 and EIC Sustainable Event Standards are helping define best practices across the industry.

How to Measure Sustainable Impact

Tracking sustainability isn’t guesswork it’s data-driven.

Here are key KPIs to monitor:

- Waste diversion rate (recycling vs landfill)

- Energy usage per attendee

- Carbon emissions from travel and power

- Water consumption

- Attendee travel modes

Use standards like ISO 20121 or GRI Event Organiser Supplements, and sustainability tech like SAM to automate reporting.
