Tasks like washing clothes are certainly mundane and time consuming. Well, for those who can’t bear the thought of washing and drying their jeans, heed advice from the CEO of Levi Strauss.

Recently, Chip Bergh gave a talk at Fortune's Brainstorm Green conference. The most important topic discussed pertained to sustainability, specifically the company’s pledge to going green.

Bergh’s biggest concern is water usage. Surprisingly, he revealed the pair of jeans he was wearing at the event hadn't been washed at all in roughly a year.

The company strives to reduce water usage overall and as a suggestion Bergh asked owners of Levi jeans to take that idea home with them and stop washing their jeans altogether.

Clearly, that isn’t something a lot of people would be willing do, but there are other planet-saving options, like purchasing a pair of the company’s new conservation-friendly Waterless jeans.

Levi’s is also working on a technique that would reduce the amount of energy and water needed to make Dockers.
