Going big and going green can work together for Hong Kong mega-events

Hong Kong's thriving mega-event economy hosted over 130 events in the first half of 2026, attracting 1.75 million visitors and generating HK$5.8 billion for the local economy. Key events like Coldplay and Blackpink concerts, as well as the 2025 Hong Kong Sevens, showcased the economic benefits. However, behind the glitz and glamour, these events also prioritize environmental sustainability.

Coldplay's 94% return rate for LED wristbands and a 59% reduction in tour emissions exemplify this commitment. Blackpink's YG Entertainment introduced carbon tracking for their 2026 Hong Kong concert, and the 2024 Paris Olympics achieved a 50% reduction in carbon emissions. As sustainability gains importance, Hong Kong should actively contribute to greening its mega-event economy.

A report from Our Hong Kong Foundation estimates that greening events could bring in an additional HK$1 billion annually while reducing emissions. While some may fear strict environmental rules deter events, Singapore's experience shows otherwise; MICE events grew after the introduction of a sustainability roadmap in 2022. With the upcoming Climate Action Plan 2050 update, Hong Kong can position its event industry as a global leader in sustainability.

The government should make green events a strategic priority in the update and create a decarbonisation road map for large-scale events. By mandating green event plans for flagship events like Art Basel and the Hong Kong Sevens, the government can showcase sustainable best practices and secure global visibility. Incorporating green operating clauses into tenders for MICE events and establishing a centralised green supplier directory can further promote sustainability.

A potential "green premium" subsidy scheme can help offset the higher costs of sustainable alternatives. Overall, integrating green standards into the event infrastructure will ensure Hong Kong's continued success as a premier event host.
