When people think about green laundry, they think about detergent. But the detergent is usually not the biggest part.^†

Quick answer: studies suggest most of a load's footprint comes from energy: heating water and running the dryer. Washing cold and line drying are the biggest wins.^†

The big pieces

What matters most

1. Wash cold (read it).
2. Line dry when you can (read it).
3. Run full loads.
4. Pick lighter packaging and formats.^† for any shipping-weight claim about sheets.

The dryer is a big energy user. The clothesline is a big energy saver. Science!

Where detergent fits

Detergent still matters for packaging, shipping and what goes down the drain. It's just one piece of the picture.
