Sustainability is no longer an optional extra for the meetings and events sector. It has become a core requirement, shaping how conferences, venues and organisers operate.
Across the industry, there is growing recognition that events need to demonstrate measurable environmental responsibility, particularly as organisations face increasing pressure to reduce emissions and provide credible ESG reporting. Recent industry data highlights just how significant this shift has become.
Events are under increasing carbon scrutiny
Research shows that a single major conference can produce around 1,200 metric tons of CO₂e, depending on scale and attendee travel patterns, with transport often representing the largest share of the footprint.
In fact, studies suggest that 70% to 90% of total event emissions come from attendee travel, reinforcing why venue choice, hybrid attendance models and sustainable transport are now central to event planning decisions.
This growing awareness is driving action across the sector. Recent analysis found that 89% of event organisers now plan to offset 100% of their event emissions, signalling a clear shift from awareness to active carbon management.
Sustainability is now influencing venue choice and delegate expectations
Beyond operational emissions, sustainability is increasingly shaping decision-making across the sector. A recent survey showed that 83% of industry professionals now identify sustainability as a top priority, with organisations actively integrating ESG principles into event planning and procurement processes.
Attendee expectations are also changing. Research shows that 71% of millennial and Gen Z delegates consider sustainability to be a key factor when choosing events, while 75% report higher satisfaction when sustainable practices are communicated clearly.
This shift is having a direct impact on how event organisers choose their venues. Spaces are being evaluated not only on location and cost, but on their ability to demonstrate credible sustainability performance and environmental action.
Venues are responding with stronger sustainability frameworks
In response, venues are investing in energy efficiency, waste reduction, and transparent reporting systems. However, there is also a growing emphasis on independent verification and certification , as events planners look for proof that a venue’s sustainability claims are credible and measurable. This reflects a wider industry trend: sustainability is moving from voluntary reporting into structured accountability supported by third-party validation.
For venues and organisers wanting to formally demonstrate their commitment, our Green Meetings award provides a sector-specific framework designed for conferences, hotels, and event spaces. It independently verifies sustainability performance across people, places, and planet, helping venues provide clear, credible evidence of their environmental and social impact.
Sustainability is now firmly embedded in the expectations of the events sector. With emissions under scrutiny and delegates prioritising responsible choices, venues and are under growing pressure to show measurable, verified progress.
The direction of travel is clear: sustainability is no longer a differentiator; it is becoming a baseline requirement for successful events.
