This Return on Investment (ROI) study was sponsored by Winrock International through its USAID-funded Developing a Sustainable Cookstove Sector project. It examines the organizational impacts of Empowered Entrepreneur Training Handbook (EETH) activities, which were developed to support organizations that engage women entrepreneurs or sales agents in order to ultimately enhance the distribution and sale of cleaner cookstoves through increasing the personal agency, business skills, and leadership skills of entrepreneurs (particularly female entrepreneurs) that sell cleaner cookstoves.
