Olympic Sustainability Impact Tracker
Overview: This tool utilizes the Olympic Sustainability Model, developed in 2021, to provide estimates of the Olympic Games' impact across three key dimensions: ecological, social, and economic. It helps users understand the event's sustainability score, which evaluates factors like new construction, event size, and visitor footprint.
Our free online calculator utilizes the Olympic Sustainability Model to provide clear, data-driven insights into the real sustainability performance of the Olympic Games. This scientific calculator offers approximate estimates, answering your key questions about the event's comprehensive ecological, social, and economic impacts.
Understanding the Olympic Sustainability Model
The International Olympic Committee (IOC) formally integrated sustainability as a core pillar in 1992. Following various Olympic events guided by IOC strategies, researchers Müller et al. introduced a systematic Olympic sustainability model in 2021. This model, detailed in "An evaluation of the sustainability of the Olympic Games," provides a structured assessment across three critical dimensions.
The Three Dimensions of Sustainability
1. The Ecological Dimension
This area assesses the event's material and environmental footprint, focusing on key factors.
- New construction: Evaluates the raw materials and resources required for building or renovating competition venues.
- Event size: Considers the number of accredited persons relative to venue capacity and usage.
- Visitor footprint: Accounts for transportation fuel consumption and the spatial requirements for accommodating all participants.
A larger number of athletes and spectators typically leads to increased flights and other transport modes, elevating the ecological impact.
2. The Social Dimension
This dimension examines how the event meets the needs of the host city's population and affects marginalized groups.
- Public approval: Gauged through polling data and general community support.
- Social safety: Measures the number of people displaced due to the Games' infrastructure and operations.
- Rule of law: Assesses the extent and severity of legislative changes enacted for the event.
Measures such as banning public demonstrations, implementing widespread surveillance, or significant police mobilization, as observed in some host cities, can substantially lower the social dimension score.
3. The Economic Dimension
Economic efficiency analyzes how effectively financial resources are utilized for hosting.
- Budget balance: Scrutinizes cost overruns and how such funds could have been allocated to other public projects.
- Financial exposure: Looks at the proportion of public funding diverted to the Olympics from other potentially beneficial investments.
- Long-term viability: Evaluates the amount of reusable venues, aiming to avoid underused "white elephant" facilities.
The 2014 Sochi Games remain the most expensive, with estimated costs around US$50 billion, raising significant questions about economic efficiency.
How to Calculate the Sustainability Score
The Olympic sustainability score operates on a 0 to 100 scale, where 100 represents the ideal outcome with minimal negative impact or highest efficiency. Let's examine the Barcelona 1992 Olympics as a case study.
For each dimension, individual criterion scores are averaged. For example:
Ecological Score = (Criterion_1 + Criterion_2 + Criterion_3) / 3
The underlying data and specific criteria for scoring are derived from comprehensive academic research.
Comparing Summer and Winter Olympic Games
When using the calculator, you can select between Summer and Winter Games, as this choice influences the overall assessment. Notable differences exist between the two.
- Winter Olympics generally have a smaller visitor footprint and require less urban infrastructure, affecting fewer residents.
- Summer Olympics often boast greater long-term venue viability and may receive higher public approval due to broader community involvement.
However, a smaller scale does not automatically guarantee higher sustainability, as demonstrated by Sochi 2014's poor performance. Interestingly, Winter Games tend to report lower estimated CO2 emissions overall.
Assessing the Sustainability of Paris 2024
Applying this model, the Paris 2024 Olympics achieved a sustainability score of 40 out of 100, placing it 11th in the historical rankings.
- Its weakest aspect was the social dimension, scoring 26.67, largely due to significant resident evictions and strict legal restrictions.
- Ecologically, challenges included the massive event scale and logistical complexities.
- Economically, it performed better, with a focus on building venues for long-term, eco-friendly use.
Despite these challenges, Paris 2024 is projected to have one of the lowest carbon footprints in Olympic history, with an estimated 1.75 Mt CO2 eq, second only to Beijing 2022. A full and final assessment may require more time after the event's conclusion.
Frequently Asked Questions
How can the Olympics become more sustainable?
To enhance sustainability, organizers should control visitor numbers, reduce the overall event size, rotate event locations within host cities, and strictly enforce sustainable practices and standards.
Which Olympic Games was the most sustainable?
According to the model, the 2002 Salt Lake City Winter Olympics is ranked the most sustainable event, with a total score of 71 out of 100.
Which Olympic Games was the least sustainable?
The 2014 Sochi Winter Olympics was the least sustainable, scoring an average of 24 out of 100, with particularly low economic efficiency. The 2016 Rio de Janeiro Summer Olympics also scored poorly (29/100) due to social disruption and poor post-Games venue use.
What is the IOC Sustainability Strategy?
Launched in 2017, the IOC Sustainability Strategy is a framework designed to integrate sustainability into all aspects of the Olympic Games and the broader Olympic Movement, aligning with the United Nations Sustainable Development Goals (SDGs).
What constitutes a good sustainability score?
A score of 75 is considered the minimum threshold for a fully sustainable Olympic event. Achieving this requires effective management and positive outcomes across all ecological, social, and economic impact areas.
