It’s “Techno-forward Tuesday” in GSB News & Notes column. First, we take a dive into a new global list of the 50 biggest solar systems at stadiums and arenas. Then we look at Nike and its commitment to reduce its carbon emissions, and those of its supply chain, via the tenets of the Science Based Targets initiative. Adhering to those tenets means the Beaverton, OR company would be doing its part to keep global carbon emissions at levels that will keep the world below a 2°C increase vs. pre-industrial levels.
INDIANAPOLIS MOTOR SPEEDWAY LEADS THE LIST OF 50 BIGGEST SOLAR SYSTEMS AT STADIUMS AND ARENAS
Szabolc Magyari, writing in the September 5th issue of SolarPlaza, a Rotterdam, Netherlands-based newsletter about all things solar, compiled a list of the 50 biggest solar systems at stadiums and arenas, with “biggest” defined as the amount of power generated per system. Click here for the list.
Three nuggets stood out to me.
1. Auto Racing Leading on Big Solar Installations: Auto racing venues’ prominence at the top of the list — three of the four biggest solar installations at stadiums/arenas are in the motor sports world — may be surprising to many at first glance. After all, burning copious amounts of fossil fuels is an essential part of the sport itself (save for the notable exception of the all electric vehicle Formula-E circuit) and, in the United States at least, the perception — if not the reality — is that the epicenter of auto racing fandom is in states where climate change denial is highest. So why are auto racing venues going solar so…bigly?

When you realize that the footprint (size, not carbon) of a raceway or speedway is 3-4X that of the biggest stadium, then it makes sense that their solar arrays would be much bigger, too. And the fact that the cost curve is decreasing rapidly makes solar an economically wise choice. And it may well be that the motor sports industry is ahead of a portion of its fan base on climate change, at least as of now. Hopefully, these solar installations, in at least a small way, will help bring some of those fans around.
2. The Netherlands Punches Way Above Its Weight, Solar Stadium/Arena-Wise. The USA leads the way on the Solar Top 50 list with 21 stadiums/arenas or 42 percent, an impressive showing, especially considering the US only represents 4.4 percent of the world’s population of 7.5 billion.
Even more impressive is the Netherlands’ solar-stadium performance: It has seven stadiums/arenas on the list which represents 14 percent of the total. But at 17 million and change, the Netherlands represents only 0.2 percent of the world’s population. Thus, it has 85 times more solar-topped stadiums and arenas than its population would indicate. Hartelijk gefeliciteerd*, Netherlands!

3. How Great Is It That There Is a Top 50 Solar Stadium/Arenas List At All?! If there’s a Top 50 list of solar stadiums and arenas, that means there must be many more such buildings who didn’t make the list. Which is a great thing, indeed.
NIKE STEPS UP ITS GREEN GAME: JOINS SCIENCE BASED TARGETS INITIATIVES; LAUNCHES ‘SUSTAINABLE LEATHER’ SHOE
Nike, a leader in the sustainable athletic apparel world, recently committed to set corporate emission reduction targets through the Science Based Targets (SBT) initiative, pushing the number of companies pledged to the scheme beyond 300.
The SBT initiative, a partnership between CDP, WRI, WWF and the UN Global Compact, judges a corporation’s greenhouse gas (GHG) emissions targets to qualify as “science-based” if they are in line with the level of decarbonization required to keep the global temperature increase below 2°C compared to preindustrial temperatures, as described in the Fifth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC).
All firms looking for the SBT initiative stamp of approval will need to take the necessary steps to embed science-based targets amongst their suppliers. This is particularly acute for the apparel world in general and the athletic apparel segment in particular as more than 90 percent of apparel brand emissions are located in the supply chain.
In 2017 alone, more than 90 companies have joined the initiative. Aside from Nike, that list includes global corporate heavyweights Colgate-Palmolive, HP, Mars^, Nestlé, and SAP.
Conspicuous by its absence to this point in the SBT initiative is adidas, Nike’s chief global competitor, and a true Green-Sports leader. Puma, an early Green-Sports adapter, is part of the initiative.
According to Matt Mace, writing in the September 18 edition of edie.net, companies that have joined the Science Based Targets initiative represent around “$6.5 trillion in market value and are responsible for 0.750 metric gigatonnes of CO2 emissions annually” — or 7.8 percent of the 9.74 metric gigatonnes# of CO2 that were emitted globally in 2015.
“As more and more companies see the advantages of setting science-based targets, the transition towards a low-carbon economy is becoming a reality,” said Lila Karbassi, UN Global Compact’s chief of programmes. “This is becoming the new ‘normal’ in the business world, proving that a low-carbon economy is not only vital for consumers and the planet, but also for future-proofing growth.”
Flyleather will help Nike move towards its Science Based Targets
Nike, while on the right path emissions reduction-wise, has a long way to go (as do practically all companies) to actually achieve its target for a 2°C or less world. Its latest eco-sartorial innovation, the recently launched Flyleather — a sustainable leather material made with 50 percent recycled leather fibers — is a step in the right direction.
While the product looks and feels just like premium leather, the process used to produce it is 180 degrees different than the traditional curing, soaking and tanning approach.
During a typical leather manufacturing process, up to 30 percent of a cow’s hide is discarded. To make Flyleather shoes, Nike collects the discarded leather scrap from the floors of tanneries and turns them into fibers. The recycled fibers are then combined with synthetic fibers and fabric through a hydro process with a force so strong it fuses everything into one material.
Nike partnered with E-Leather, which pioneered the process, to develop the new material, which they claim is 40 percent lighter and five times as durable as traditional leather due to its innate structural strength and stability. The process to produce Flyleather also uses 90 percent less water and has an 80 percent lower carbon footprint than traditional leather manufacturing. And because Nike Flyleather is produced on a roll, it improves cutting efficiency and creates less waste than traditional cut-and-sew methods for full-grain leather.
The first product to feature Nike Flyleather is the Nike Flyleather Tennis Classic, an all-white version of the premium court shoe.

“One of our greatest opportunities is to create breakthrough products while protecting our planet,” said Hannah Jones, Chief Sustainability Officer and VP of the Innovation Accelerator at Nike. “Nike Flyleather is an important step toward ensuring athletes always have a place to enjoy sport.”
