The Paris 2024 Olympics showcased significant progress in reducing the environmental impact of hosting such a global event, achieving a remarkable 54.6% reduction in carbon dioxide emissions compared to previous Games in London and Rio. This milestone was announced by the organizers, marking a promising shift toward more ecologically responsible sporting events.

The emissions for the Paris Olympics totaled 1.59 million tonnes of carbon dioxide, which, while substantial, signals a move toward sustainability within the framework of large-scale international competitions. This achievement is part of a broader commitment by the Paris 2024 organizers to host a "more responsible" Games, focusing on environmental, social, and economic aspects.

Despite these advancements, the Games were not "carbon neutral". A significant portion of the emissions—more than half—was attributed to spectator travel, a challenging aspect to mitigate given the global nature of the event. This continues to pose questions about the full environmental impact of the Olympics and highlights areas where further improvements are necessary.

The approach taken by Paris can serve as a valuable learning tool for future hosts. Looking ahead to the Los Angeles 2028 Olympics, there are critical takeaways and opportunities for even greater reductions in environmental impact. Lessons from Paris 2024 emphasize the importance of addressing transportation emissions, promoting local attendance, and possibly integrating digital viewership solutions to reduce travel demand.

Additionally, Los Angeles can build on the sustainable initiatives of Paris by investing in more comprehensive carbon offset projects and innovating in green technologies. By planning for eco-friendly infrastructure and renewable energy sources, LA 2028 has the potential to set a new standard in sustainable event hosting, drawing on the lessons learned from Paris to not only repeat but also enhance the achievements in reducing the carbon footprint of the Games.

Given the ongoing climate crisis, the message is clear: future Olympic Games must continue to embrace and push for sustainability, making environmentally conscious decisions central to their operational planning. This approach not only benefits the planet but also sets a precedent for other large-scale events worldwide.
