Eco-fashion retailer H&M's latest environmental campaign will support WaterAid. With the Water collection, complete with swimsuits and other summer must-haves for the beach, H&M plans to donate 25 percent of those sales to the international nonprofit.

Beyoncé, who embarks on her Mrs. Carter Show World Tour today, will appear in commercials for the campaign and debut new song, "Standing on the Sun," in May. 

WaterAid improves access to clean water and sanitation for communities in need across the globe. The organization works on the ground to implement sustainable projects and on the policy floor to support water protection.

Over the past ten years, H&M’s initiative with WaterAid has raised $3.9 million. The collection will be available in stores and online in May.
