The Global Destination Sustainability Index (GDS-Index) has released its 2025 results, marking the programme’s 10th anniversary with a striking snapshot of progress.
Helsinki once again takes the leadership position with a score of 93.52%, while Adelaide has been crowned the year’s most improved destination.
Helsinki’s tourism director Nina Vesterinen welcomed the achievement: “We are so happy with this result because Helsinki invests substantially in sustainable development, and this recognition reaffirms our right direction.” The Finnish capital’s accomplishments include ending its coal era and securing near-universal sustainability certification across hotels, convention centres, and major attractions.
Adelaide rose 23 places in the rankings, a remarkable leap in only its second year of participation. Business Events Adelaide CEO Damien Kitto called the recognition a milestone: “It is fantastic to see such a significant improvement in such a short time.” The city’s progress was anchored by its Integrated Climate Strategy 2030 and the achievement of carbon neutrality at Adelaide Airport.
The 2025 theme, Shifting Tides, reflects a global industry in transition. Guy Bigwood, CEO of GDS-Movement, noted: “Every destination featured in the GDS-Index has demonstrated leadership and commitment – each one deserving recognition for its efforts to build a more regenerative future.”
