The convention and events industry has a unique opportunity to make a positive impact in an era when sustainability and environmental consciousness are gaining paramount importance. Convention bureaus, as key players in this industry, have a crucial role to play in promoting and fostering sustainability practices. This article explores the influence convention bureaus wield in shaping a sustainable event industry, examining their role, initiatives, challenges, and the potential benefits of their efforts. Convention bureaus serve as intermediaries between event organisers and destinations, providing support and resources to navigate the destination and engage with local suppliers. The Strategic Alliance of the National Convention Bureaux of Europe recognises the urgent need for transformative change and is committed to sustainability efforts. They advocate for action, collaboration, and alignment with international goals and initiatives. Convention bureaus can implement certification programs, provide education and training, and foster collaboration and partnerships to drive sustainable initiatives. Sustainable practices offer benefits such as reducing environmental impact, promoting social responsibility, and creating economic opportunities. However, challenges include financial constraints, lack of awareness, and measuring impact and accountability.
