Nike unveiled a big new sustainability initiative as millions around the world prepared to strike for action on climate change

Though the runners came just shy of breaking two hours — elite runner Eliud Kipchoge ran the fastest marathon in history at two hours and 25 seconds — it demonstrated Nike's dedication to product innovation.

According to their findings, "under current trends climate change could decrease time spent on the field by up to two months in parts of Louisiana, Texas and Mississippi by 2050."

"Las Vegas is one of the fastest warming cities and this summer I really experienced that heat," she said. "It was very different than any of the other summers when I've been training. It felt like I was walking in an oven just going to do my warm-up lap."

"That's why I chose an indoor sport," Olympic fencer Ibtihaj Muhammad quipped.

According to the Climate Impact Lab's findings, the average number of global "quality" snowboarding days has decreased by 7% in the last 30 years and could decline as much as 22% by 2025.

The company has invested significantly in its circular design efforts, which focus on the core principles of sustainable material choices, recyclability, waste avoidance, and green chemistry, among others.

Move to Zero also includes eliminating single-use plastics on global Nike campuses and investing in existing circular design products, such as its FlyKnit shoes and jerseys, which are constructed from recycled plastic bottles.

Nike operates Reuse-A-Shoe and Nike Grind programs that convert shoes into new products, as well as running tracks and courts.

"We know we can't do this alone. Climate change is a massively complex problem that's going to require complex solutions and relentless partnership across our industry and beyond, and frankly, even with some of our direct competitors," he said.
