Episode notes
Clothing's Big Climate Footprint
- The fashion industry generates about 10% of global greenhouse gas emissions, making clothing a major climate actor.
- The most sustainable garment is one already used, so buying secondhand usually beats buying new.
Don't Trust Vague Green Labels
- Avoid vague marketing like "natural" or "biodegradable" without supporting evidence or certifications.
- Look for specific certifications, measurable targets, and detailed company reporting before trusting claims.
Recycling Isn't Usually Closed-Loop
- 'Recycled' often means synthetic fibres from other sources, not closed-loop garment-to-garment recycling.
- Only about 1% of discarded textiles enter true closed-loop recycling today.
