Angie, I should clarify. I know they're trying and I applaud them for that. It's a very complex business and I appreciate how futile it is to hold retailers to an unrealistic standard when the whole machine is so close to breaking point.
On the other hand, the fast fashion model is built around selling large volumes of low cost garments with a limited lifespan which can't be realistically recycled or otherwise disposed of in the volumes they're currently being produced. This is a very valid criticism, it's an enormous environmental burden, hence the accusations of greenwashing aimed at H&M.
To put it another way, I think large retailers like H&M (who are far from the biggest offender here) could do a great deal more for sustainability by reframing the business model and actively helping to rethink the way we consume clothes. For example, I'm quite certain Uniqlo are no better in terms of environmental policy at the front end, but I deeply appreciate their commitment to supplying a well designed, durable product with a focus on lifestyle rather than the current fashion cycle.
Anyway. I hope I haven't derailed the thread into a discussion about sustainability in fashion, because as usual I'm overthinking all this. Please carry on.
