Our Sustainable Events MOT is a practical audit of your live event, assessing performance across nine key sustainability themes and scoring each from 1 to 5.
We can observe your event in action, review attendee communications and work with your organisers, suppliers and stakeholders to build a complete picture of your sustainability performance. You’ll receive a clear scorecard, practical recommendations and a roadmap for continuous improvement.
For organisations looking to embed sustainability more deeply, we also support teams in implementing the ISO 20121 framework and preparing for certification with an accredited body. From gap analysis and documentation to coaching and hands-on guidance, we’ll help you build a robust management system and achieve certification with confidence.
We believe sustainability should be practical, not overwhelming.
Drawing on experience across a wide range of events, we help teams take realistic, achievable steps that deliver meaningful impact. By balancing ambition with practicality, we help you make informed decisions with confidence.



Abena and her fantastic team at Legacy Events were impressive in supporting our sustainable cycle race series over the last two years. The knowledgeable and insightful team fully and seamlessly integrated into our event operation. Abena & Legacy understood and addressed the needs of sustainable event operations and delivered these at the highest level.
Richard Bate, EBK

Legacy Sustainable Events training was insightful, informative and engaging. The course was a careful balance of education, discussion, Q&A and importantly; tangible tools for planning and how to integrate sustainability into the execution of any event. The interactive sessions, working together as a team was great to get a sense of how much knowledge is already out there – and how much more work, collectively there is to do. I would highly recommend this course to any company that takes sustainability seriously – especially those who are not quite sure how to approach or integrate it. Legacy have created a very honest, welcoming, fun and safe space to genuinely explore this subject.
Events team, Permira

Abena provided a thorough and insightful training course with excellent examples of how to implement sustainability into our upcoming events. The interactive session allowed our group to discuss topics and better understand them in order to apply them to our daily job responsibilities. Abena was incredibly knowledgeable and informative in a totally non- intimidating way so our group felt at ease to ask any question. I would thoroughly recommend Legacy's services..
