Good Housekeeping recently published a list of tips from celebrity moms on going green. Julia Roberts actually turns to her yoga instructor, Sophie Uliano, with all her eco questions. Uliano actually started a green group for Roberts and her pals to teach them about nontoxic cosmetics and safe cleaners. The result? One of America’s sweethearts making her own eco friendly cleaning spray, keeping a journal on her environmental concerns, checking labels, and planting an organic garden. Go Julia! You can get Uliano’s advice in her new book, Gorgeously Green.

“I’ve made homeopathic treatments and aromatherapy treatments. I’m constantly looking for the best products out there, and I helped my hairdresser launch a line of organic hair-care products, free of animal products as well as parabens and sulfates called David Babii for WildAid. Ten percent of the money goes toward protecting endangered species,” shares bouncy Kate Hudson on her green habits. Kate’s also pretty creative with her vegetables.
