The document provides guidance for green entrepreneurs in developing a green business. It outlines a step-by-step process for sketching an initial business idea, identifying problems and needs the business aims to address, building the business model, testing it, and implementing/improving the business. The workbook uses three case studies to illustrate the process, including an energy services company providing solar energy to rural communities in Algeria. The case studies show entrepreneurs working to address issues like unreliable electricity access, e-waste management needs, and creating organic cotton products. The workbook guides entrepreneurs through exercises to flesh out their business idea and model at each step of the process.
