Under Armour has retracted its science-based climate targets, increased absolute emissions, and disclosed almost no supply chain decarbonization strategy. The company reports Scope 3 emissions but provides zero category breakdowns. Biodiversity, water stewardship, and circular design remain largely unaddressed despite significant exposure in cotton and synthetic supply chains.
