San Fransico-based Method Products, Inc announced last week that it has received Cradle to Cradle (C2C) product certification on more than 15 of its eco-friendly cleaning products as their green steps.

These products include Method’s liquid dish soap, hand wash, and foaming hand wash. The company is in the process of certifying another 20  products.

C2C certification involves a thorough evaluation of a product’s ingredients, manufacturing, and packaging. Key components of C2C certification include the use of: healthy and environmentally safe materials,renewable energy, and corporate practices that promote social responsibility.

“Method is committed to making products and packaging that are green to the core, like our business,” says Adam Lowry, Method co-founder and chief greenskeeper.“Obtaining third party verification from the people who literally wrote the book on cradle to cradle design reinforces the work that we’re doing, and it tells consumers that in a category filled with green noise, Method is a company they can trust.”

“Method welcomes investigation and scrutiny of our products and our business practices,” Lowry concludes. “We encourage consumers to examine not only what a company puts on the shelf, but what it does behind closed doors. At Method, we believe a green product can only come from a truly green company.”
