Why Eco-Friendly Fashion Is More Relevant Than Ever
Fashion is one of the most polluting industries in the world. Think:
- 10% of global carbon emissions
- 20% of global wastewater
- Over 100 billion garments made annually — most of which end up in landfills
In a world increasingly affected by climate change, fast fashion’s glossy façade is cracking. More shoppers (especially Gen Z and Millennials) are demanding transparency, ethical practices, and better-quality pieces that last.
And guess what? The industry is finally responding — and doing so with serious flair.
How to Spot a Truly Sustainable Brand
Let’s get one thing straight: “greenwashing” is real. Just because a brand slaps on a “conscious” label doesn’t mean it’s doing the work. So how do you spot a genuinely eco-conscious brand?
Look for:
- Transparent supply chains
- Use of recycled or organic materials
- Fair wages and safe working conditions
- Carbon-neutral or low-impact production methods
- Take-back or resale programmes
Bonus points for brands that publish sustainability reports, share their factory info, or use third-party certifications (like GOTS, OEKO-TEX, or B Corp).

Switching to a greener wardrobe doesn’t mean throwing out everything you own. Start small, get intentional, and have fun with it.
Quick Wins:
