What Drives Us

Responsible Sourcing Network (RSN), a project of the nonprofit organization As You Sow (www.asyousow.org), is dedicated to ending human rights abuses and forced labor associated with the raw materials found in products we use every day. RSN builds responsible supply chain coalitions of diverse stakeholders including investors, companies, and human rights advocates. Currently, RSN works with network participants to leverage their influence in the areas of conflict minerals from the Congo and forced labor in the cotton fields of Uzbekistan to create positive change for brands, consumers, and the impacted communities.
