Ranked 9th in the prestigious Global Destination Sustainability Index (GDS-Index) in 2024 — higher than any other UK or Irish city — Belfast is proving that sustainability and growth can go hand-in-hand. From pioneering net-zero hotels to a thriving food scene that champions locally sourced ingredients and zero-waste practices, the city is setting new standards for responsible tourism and ethical dining. But does it truly deserve the title of the most sustainable city in the region? Let’s explore the data, initiatives, and culinary leaders shaping Belfast’s green revolution.

Belfast has emerged as a beacon of sustainability, not only within the UK and Ireland but also on the global stage. In late 2024, the city secured 9th spot among 100 international destinations in the Global Destination Sustainability Index (GDS-Index), positioning it as the most sustainable visitor destination in the UK and Ireland.
This remarkable achievement is the result of collaborative efforts by Visit Belfast, Belfast City Council, and a wide range of tourism industry partners.
