Olympic Games Sustainability Calculator
Evaluate the ecological, social, and economic sustainability of 18 Olympic Games from 1992 to 2024 using the Olympic Sustainability Model by Müller et al. published in Nature Sustainability.
About This Calculator
The Olympic Games Sustainability Calculator evaluates how sustainable each Olympic Games has been since 1992 across three key dimensions: ecological impact, social responsibility, and economic efficiency. Built on the Olympic Sustainability Model developed by M\u00fcller et al. (2021) and published in Nature Sustainability, this tool provides a comprehensive sustainability score for all 18 Olympic Games from Barcelona 1992 to Paris 2024.
The model assesses each Olympic edition across nine indicators: ecological factors include new construction intensity, event size, and visitor footprint; social factors include public approval, social safety of affected communities, and rule of law changes; economic factors include budget balance and cost overruns, financial exposure through public funding, and long-term venue viability. Each indicator is scored from 0 (not sustainable) to 100 (very sustainable), then averaged within each dimension and normalized to produce a total out of 100.
Regional Notes
Global: This calculator covers Olympic Games hosted across the world, including North America, Europe, Asia, South America, and Oceania. The sustainability model applies equally to all host nations and regions.
Key Findings: Salt Lake City 2002 ranks highest at 71/100, while Sochi 2014 ranks lowest at 24/100. The overall trend shows declining sustainability over time, with no Olympic Games achieving the 75-point threshold for full sustainability. The Paris 2024 Olympics scored 40/100, ranking 11th, with its strongest performance in economic efficiency and lowest in social impact due to displacement of residents and severe legal restrictions.
Frequently Asked Questions
How does the Olympic Games sustainability calculator work?
Select an Olympic Games year from the dropdown. The calculator uses the Olympic Sustainability Model developed by M\u00fcller et al. (2021) published in Nature Sustainability, which evaluates each event across nine indicators divided into three dimensions: ecological (new construction, event size, visitor footprint), social (public approval, social safety, rule of law), and economic (budget balance, financial exposure, long-term viability). Each indicator is scored 0-100, averaged per dimension, and normalized to produce a total sustainability score out of 100.
Which Olympic Games was the most sustainable?
According to the Olympic Sustainability Model, the 2002 Salt Lake City Winter Olympics is the most sustainable Olympic event since 1992 with a total sustainability score of 71/100. It performed exceptionally well across all three dimensions, particularly in economic efficiency with minimal cost overruns and high venue reusability.
Which Olympic Games was the least sustainable?
The 2014 Sochi Winter Olympics is the least sustainable Olympic event since 1992 with a score of 24/100, driven by massive cost overruns (estimated US$50 billion), low public approval, and poor long-term venue viability. The 2016 Rio de Janeiro Summer Olympics also scored poorly at 29/100 due to social disruptions and underutilized post-event venues.
What is the Olympic Sustainability Model?
The Olympic Sustainability Model is a systematic evaluation framework developed by researchers at the University of Lausanne and published in Nature Sustainability in 2021. It measures sustainability across three dimensions: ecological (new construction, event size, visitor footprint), social (public approval, social safety, rule of law), and economic (budget balance, financial exposure, long-term viability). Each dimension comprises three indicators scored from 0 to 100.
What is a good sustainability score for the Olympics?
A sustainability score of 75 or higher out of 100 is considered the minimum threshold for a completely sustainable Olympic event. Scores between 50-74 indicate good sustainability, 35-49 moderate sustainability, and below 35 poor sustainability. No Olympic Games since 1992 has achieved a score above 75, with Salt Lake City 2002 ranking highest at 71.
How can the Olympics be made more sustainable?
Based on the research by M\u00fcller et al., three key actions would make Olympic hosting more sustainable: first, greatly reducing the size of the event including the number of athletes, venues, and visitors; second, rotating the Olympics among the same host cities to leverage existing infrastructure; third, enforcing independent sustainability standards and accountability measures for host committees.
How do Summer and Winter Olympics compare in sustainability?
Winter Olympics generally have a smaller visitor footprint and displace fewer people due to smaller scale, but Summer Olympics tend to have higher long-term venue viability and greater public approval. Neither category is inherently more sustainable, as shown by Sochi 2014 (Winter) being the least sustainable and Salt Lake City 2002 (Winter) being the most sustainable.
