During Billie Eilish's July shows at Manchester's Co-op Live Arena, the venue reduced food-related emissions by 47 percent by offering a fully plant-based menu. This initiative also conserved 3.5 million litres of water and showcased options such as plant-based burgers, hot dogs, saucy chips, and the "Billie Burrito" with vegan ingredients. Executive chef director James Hart noted that fans embraced the plant-based options, and he predicted more plant-based food offerings at the arena in the future.

As part of the same tour, the London O2 Arena also implemented a plant-based menu at Eilish's request. Each show featured a short film about veganism and sustainability efforts, along with an educational 'Eco Village.' This sustainable approach aligns with Co-op Live Arena's existing green initiatives, including solar panels, rainwater harvesting systems, and a zero waste-to-landfill policy. Overall, the success of Billie Eilish's plant-based menu highlights the positive impact of showcasing sustainable practices in the entertainment industry.
