Namaste — and [redacted] off Lululemon: Over 1.6k (and counting) yoga teachers and students from 30 countries have published an open letter to global athletic apparel brand Lululemon, calling on the company to “practice what [it preaches]” when it comes to mindfulness and wellness. Lululemon markets itself as eco-friendly and sustainability-focused, notes the Guardian. But this is at odds with its reliance on coal, which is used to power almost half of its factories, the letter’s signatories say, calling on Lululemon to commit to immediately phasing out coal and sourcing 100% renewable energy across its supply chain.
