Pаssаge 5: The оrgаnizers оf the Paris Olympic Games have оutdone their predecessors in trying to make the Games the most sustainable in the decades since climate change became a concern. But with an estimated 11 million tourists converging on the City of Light for the Olympics, including 1.5 million from abroad, the Games can only be so green.On the plus side, organizers have been serious in their efforts to reduce carbon emissions. They measured the expected carbon footprint of the Games, reduced emissions through energy efficiencies, limited new construction by using existing facilities, added bike lanes, minimized the use of fuel-powered generators and sourced sustainably produced goods for medals and podiums and much of the event materials.Still, international travel is a big contributor to the overall carbon impact of the Games. Organizers of the Rio Olympics in 2016 predicted that slightly more than half of the carbon emissions would come from spectators. Of that amount, 80 percent was expected to be generated by international fans traveling to and from the Games. Organizers saw a low potential to reduce those emissions and said they would need to compensate elsewhere in the preparation and running of the events.What else is to be done? If the world is serious about reducing carbon emissions, the Olympics, like so much else, will have to change even more. Jules Boykoff, who has written extensively about the Olympic Games, rightly argues in Scientific American that “the Games need to reduce their size, limit the number of tourists who travel from afar..”Thanks to television and social media, those of us who live far from the host city can still follow along in real time without traveling to the Games. Tokyo 2020, actually held in 2021, and Beijing 2022 did not have international fans because of the Covid pandemic. The planet was better off for it.In the Rio Games, organizers claimed that a “significant” part of spectator emissions, including from travel, were offset by the planting of trees, and Paris organizers hope to similarly offset emissions with reforestation and renewable energy projects. But these offsets are not a panacea.For all the efforts in Paris to reduce the carbon impact of the games, and they have been considerable, the sheer scope of future Games must be rethought. A smaller-scale Olympics wouldn’t solve everything, but it would make these events more sustainable. Which of the following are primarily used by the author to support the claim that international travel contributes significantly to the carbon emissions of the Olympics?
