At outdoor clothing supplier Patagonia, it is already a tradition to give the discount battle at the end of November a wide berth, so to speak. At German outdoor specialist Deuter, too, Black Friday is not black, but green: instead of throwing discounts around during Black Week, 10 percent of online store sales are donated to sustainable causes. Planting trees is already part of the concept at clothing label Nikin, but from November 25 to 28, two trees will be planted for every product sold. At backpack and accessories manufacturer Osprey, 20 percent of all purchases in the Green Friday sale will go to the European Outdoor Conservation Association to directly support two nature conservation projects.

Even outside of the sports industry, the signs are not only pointing to Black Friday, but also Green Friday: furniture giant Ikea is not offering a discount battle, the concept is also geared towards sustainability: the furniture store buys back used items and pays double the calculated value.
