The Olympic Movement, Environmental Protection, and Climate Change

As early as the 1990s, the IOC faced pressure to review its impact on the environment and establish policies to minimize it. This pressure was triggered by a combination of the severe effects that the Games—especially the Winter Games—had on local ecosystems, the increasing awareness of environmental problems among the general global public, and the unique nature of the Olympics as mega-events with an almost universal reach.Footnote ³ In response, by the mid-1990s, the Olympic Movement had put environmental protection prominently on its agenda and developed several initiatives and policies for its implementation.Footnote ⁴ Cooperation with the UN Environmental Programme facilitated this work.Footnote ⁵

Recently, the IOC has started a more comprehensive reform process to react to increasing societal demands towards the sports sector. To this end, it launched its Agenda 2020, a list of forty recommendations on the Olympic Movement's future, which includes two recommendations specifically on sustainability and the environment.Footnote ⁶ The IOC also aligned with the UN Agenda 2030 and its Sustainable Development Goals, which cover climate change in Goal 13.Footnote ⁷ To implement these policy advances, the IOC developed a Sustainability Strategy outlining its contribution to sustainability across three spheres: the IOC as an organization, as the owner of the Olympic Games, and as leader of the Olympic Movement.Footnote ⁸

Two aspects need to be considered when addressing climate change in the Olympic context: First, sports mega-events such as the Olympics often leave a significant environmental footprint. As such, they negatively impact the climate by being responsible for large amounts of greenhouse gas emissions through factors such as travel of teams and fans, energy use during the events, and construction.Footnote ⁹ Second, large sporting events are also prone to be affected by climate-related impacts. In the context of the Olympics, this is true for both Summer and Winter Games, with the latter being mainly at risk. Winter sports are dependent on weather conditions that are becoming increasingly scarce in many regions. A recent study led by the University of Waterloo found that if greenhouse gas emissions are not drastically reduced, only eight of the last twenty-one host cities of the Winter Olympics would provide reliable enough weather conditions to host the games by 2050.Footnote ¹⁰ Non-winter sports can be significantly affected as well. For example, high temperatures may increase health risks for athletes and spectators at outdoor events; extreme temperatures, storms, or coastal erosions may damage sports venues.Footnote ¹¹

The Olympic Movement's Contribution to Tackling the Challenges of Climate Change?

In the Paris Agreement governments agreed to “[h]olding the increase in the global average temperature to well below 2°C above pre-industrial levels.”Footnote ¹² Even though only states (plus the EU) are parties to it, the Agreement emphasises that climate action includes all levels of society.Footnote ¹³ Integration of non-state actors is also facilitated by the bottom-up approach that the Agreement adopts. Thus, states must communicate extensive climate action plans, so-called “nationally determined contributions.”Footnote ¹⁴ Here they can integrate non-state actors in manners most adequate to meet their commitments.Footnote ¹⁵ Such a collaborative spirit is also present at the transnational level. Several initiatives between the UNFCCC and non-state actors were launched with the approval of the Conference of Parties. A prominent example is the Global Climate Action Portal (NAZCA), where actors from all segments of society can display their climate change commitments. Similar to states, non-state actors determine their own contributions to tackle climate change. To date 26,975 actions by 18,119 actors are listed.Footnote ¹⁶ The Sports for Climate Action Initiative, jointly developed by the UNFCCC and the IOC in 2018, is among the non-state actors listing its commitments on NAZCA.Footnote ¹⁷

The UNFCCC also published the Sports for Climate Action Framework.Footnote ¹⁸ Various sports actors, such as federations, clubs, or Olympic Organising Committees (OCOGs), have signed up to it.Footnote ¹⁹ Participants pledge to make concrete commitments and apply verified standards for measuring, reporting, and reducing emissions.Footnote ²⁰ To this end, the Framework asks signatories to develop a “climate action agenda for sport” that sets out commitments based on five principles:

• Principle 1: Undertake systematic efforts to promote greater environmental responsibility;

• Principle 2: Reduce overall climate impact;

• Principle 3: Educate for climate action;

• Principle 4: Promote sustainable and responsible consumption;

• Principle 5: Advocate for climate action through communication.Footnote ²¹

Principle 2 is central and requires some more elaboration: Its goal is for sports actors to achieve climate neutrality for their organization and events.Footnote ²² The Framework provides critical steps through which this can be accomplished. The first step is to “measure and understand.”Footnote ²³ Here, information on activities is gathered, and a quantitative measure of the greenhouse gas emissions is established. This data is then used by decision-makers to understand the overall climate impact of their organization and activities and to determine which activities have the most significant effect.Footnote ²⁴ In a second step, the Framework asks organizations to take action to mitigate their carbon footprint. It suggests a hierarchical approach starting with avoidance of emissions, followed by their reduction and substitution, and finally, by their compensation through UNFCCC recognized mechanisms. An additional, important step is reporting the climate footprint and the actions taken to mitigate it.Footnote ²⁵

To understand how the Framework is implemented, let us now turn to the IOC and its main deliverable—the Olympic Games. On the transnational level, the IOC, rather than providing a detailed list with requirements, only sets out the general direction. Thus, in its Sustainability Strategy, the IOC has promulgated the goal of achieving “carbon neutrality by reducing direct and indirect GHG emissions, and by compensating emissions as a last resort” by 2030.Footnote ²⁶ This is to be achieved through “effective carbon reduction strategies” aligned with the Paris Agreement's goals outlined above. The Sustainability Strategy provides a list of requirements, which are applicable to the Olympic Games from 2026 onwards:

• – OCOGs and host cities [are] to minimise the Olympic Games’ carbon emission;

• – OCOGs [are] to compensate their “direct”/“owned” emission,

• – OCOGs and host cities [are] to promote low carbon solutions for and through the Olympic Games in the host country, [and]

• – Candidate cities, OCOGs, and host cities [are] to take into account the potential consequences of climate change when selecting Olympic Games locations.Footnote ²⁷

These requirements are included by reference into the IOC Host City Contract's Operational Requirements, specifically the Sustainability and Legacy Section, and thus made binding for host cities.

The Sustainability and Legacy Section further obliges the respective OCOG to develop a sustainability strategy where it must identify its specific sustainability objectives in line with the requirements in the IOC's Sustainability Strategy.Footnote ²⁸ This is done in cooperation with host country authorities, and the IOC, which also needs to give its approval before publication of the objectives.Footnote ²⁹ The OCOG's sustainability strategy must be complemented with implementation plansFootnote ³⁰ and a sustainability management system that is in line with ISO 20121:2012 on Sustainable Events Management.Footnote ³¹ Furthermore, OCOGs must prepare three sustainability reports (two pre- and one post-Games), which outline the host country's progress in delivering the sustainability strategy. These reports must conform to internationally recognized reporting standards (such as the Global Reporting Initiative standards).Footnote ³²

Additionally, OCOGs also need to develop a specific Carbon Management Plan to measure and minimize carbon emissions. For that purpose, the IOC published the Carbon Footprint Methodology Guideline, a technical document covering aspects such as methodological principles and technical guidance for measuring and calculating carbon footprints.Footnote ³³ The Guideline uses a methodology consistent with the Greenhouse Gas Protocol, ISO 14064 and the European Commission's Organisation Environmental Footprint.Footnote ³⁴ Based on it, OCOGs are to set up an iterative process where they first estimate the carbon footprint of the Games based on planning documents and assumptions. This constitutes a basis for the carbon management plan and is part of the initial carbon footprint report. In a second step, a carbon footprint reduction plan is developed and implemented. Based on this, a revised carbon footprint report is published. Finally, after the Games, the actual footprint is measured and reported.Footnote ³⁵

As this section showed, climate change regulation in the context of the Olympics is predominantly implemented contractually. Critically, the sucess of this approach depends on the capabilities of the host cities and the ability of the IOC to steer and support them. In the past, the IOC did not always succed in ensuring compliance with sutainability requirements.Footnote ³⁶ A particular problem was a sunk cost dynamic that set in once the Games were awarded. Even though host city contracts give the IOC a lot of power to determine even minor details of the events, it is difficult to enforce some of the more overarching issues, especially as the event approaches. The ultimate “stick,” the revocation of the Games, would not only affect the host city but would also be extremently damaging to the IOC. In anticipation of such problems the bidding process has become more stringent in recent years, and the IOC is more involved at the application and preparation stage providing assistance to potential host cities.Footnote ³⁷ Parts of the newer sustainability requirements are also helpful in facilitating commitments. As they emphasise the reuse of existing infrastructure and venues, they lower the burden on host cities, and make implementation easier. However, as the next section will show, successfully lowering emissions of a mega-event like the Olympics remains a challenging endeavor.

Climate Change Actions on the Ground—A Closer Look at Tokyo 2021

The OCOG of the Tokyo Olympics is a signatory of the Sports for Climate Action Framework and, thus, adheres to the Five Principles outlined above.Footnote ³⁸ Moreover, the IOC's Sustainability Strategy sets out a list of requirements, which, as mentioned, are directly and fully applicable to the Olympic Games from 2026 onwards. However, even though these requirements are not binding on Tokyo 2021, the Tokyo OCOG has aligned its practices with them.

Lowering carbon emissions already featured prominently in Tokyo's application file. One of the three pillars of its proposed sustainability strategy was to achieve “minimal impact Games,” which encompassed “carbon-neutral Games by reducing energy and resource consumption and carbon emissions, using renewable energy, public transport, and low-energy vehicles, and zero-waste policies.”Footnote ³⁹ This translated into five proposed key approaches in the sustainability strategy, which were predominantly focusing on avoidance and reduction: strategic site plan (reusing venues, and planning new ones also to reduce transport emissions), low carbon and energy facility and venues, use of renewable energy facilities, low emission, and fuel-efficient vehicles, and a carbon reduction campaign for the broader community.Footnote ⁴⁰

When awarded the Games, the bids made in the application file became binding through and together with the general obligations in the host city contract.Footnote ⁴¹ Accordingly, the OCOG must develop a sustainability strategy including a carbon management plan; there must be an implementation plan and a management system in place. Furthermore, at least three sustainability reports must be published.Footnote ⁴²

Thus, the OCOG developed the Tokyo 2020 Olympic and Paralympic Games Sustainability Plan, which includes a carbon strategy.Footnote ⁴³ The main direction in the carbon strategy is “towards zero carbon.” However, this does not mean the planners expect to arrive at zero carbon emissions, but instead refers to the ideal path actions should take.Footnote ⁴⁴ In line with the iterative approach outlined in the Carbon Footprint Methodology Guideline, the OCOG first measured the initial carbon footprint by calculating “the sum of all the activity levels multiplied by their corresponding greenhouse gas (GHG) emission intensity.”Footnote ⁴⁵ Based on this calculation, three actions (aligned with the actions under Principle 2 of the Sports for Climate Action Framework) are taken to reduce the carbon footprint: “Avoidance measures,” “Reduction measures,” and “Offset measures.”Footnote ⁴⁶

These three measures are further specified through concrete items, targets, and indicators. To illustrate this: one item in the section of emission avoidance is “strategic venue planning for the maximum use of existing venues and transport networks.” This translates into the target of reusing “a ratio of 58% of existing competition venues,” and an indicator consisting of “the number of existing competition venues used vs. the total number of competition venues.”Footnote ⁴⁷ In total, twelve items and nineteen targets are identified in the Plan. Some have already been achieved, but, overall, results are still preliminary as the Games have not yet taken place. So far, the OCOG calculated that the measures combined have led to a reduction of 0.279 million t-CO₂ compared to the business as usual scenario.

However, despite avoidance and reduction measures, 2.730 million tons of CO₂ have been or will still be emitted, so there is a significant need for offset measures. To this end, the Organisers have implemented a carbon offset program with the assistance of the Tokyo Metropolitan Government and the Saitama Prefectural Government. Businesses who participate in the cap-and-trade programs of these two administrations can implement energy-saving measures. Credits earned in this way may then be designated to offset carbon emissions from the Olympic Games.Footnote ⁴⁸ In February 2020, credits for 3,149,739 tons of CO₂ have been obtained by both programs, and the OCOG expects “to offset a certain amount of carbon emissions from the Games.”Footnote ⁴⁹

Concluding Observations and Outlook

Like many globally operating industries, the sports sector and, at its forefront, the IOC have joined the Paris pledge to reduce carbon emissions with ambitious goals that do signal a serious commitment. As with other energy-intense industries, success will depend on whether these can be successfully implemented on the ground. The main legal instrument to ensure these commitments are host city contracts. Those set binding requirements future host cities must implement. However, the ongoing preparations for the Tokyo Olympic Games show that truly reducing emissions at an event of the Olympic Games’ size is easier said than done. So far, reductions only amount to 9.2% compared to the business as usual case. The Paris Agreement and the Sports for Climate Action Framework mandate that future Games such as Paris 2024 and Los Angeles 2028 must meet their higher reduction targets.Footnote ⁵⁰ At this point it is too early for a conclusive evaluation of whether these reforms will achieve their intended outcome.
