Zipline delivers medical products via unmanned aerial vehicles (UAVs). With its expansion to Ghana in 2019, Zipline became world's largest medical drone-delivery service, reaching over 25 million people. Founded in 2014 by Keller Rinaudo (CEO) and Keenan Wyrobek (CTO) in Half Moon Bay, California, Zipline is different from its Silicon Valley peers and has big ambitions: to serve 700 million people in need of medical supplies by 2024. The case study sheds light on the company, its drone technology and its new approach to the delivery of medical supplies. It also illustrates the difficulties ahead as it expands operations.

Tom Hermans, CEO of EMMA Safety Footwear, is excited about the idea of developing the world's first circular safety shoe - one that adheres to the cradle-to-cradle design principles. This could be a transformational strategy, differentiating EMMA from the crowded safety shoe market in Europe and extending a long tradition of social responsibility since its establishment in 1931. Careful consideration and research are required because this would impact almost every aspect of EMMA's operation - the business model, internal operations, the global supply chain, and the company culture. Questions remain about whether this is the best way to differentiate EMMA. What kind of change management would EMMA and its suppliers need to deploy the circular initiative? How could the business model be reinvented to capture the economic benefits of circular shoes? Can Tom and his team push through this drastic change in a conservative company in a conservative market?

This case is the continuation of EMMA Safety Shoes (A): Designing a Circular Shoe. EMMA reached 100% circularity in shoe design at the end of 2019, but this impressive achievement did not mean its journey to the circular economy was over. EMMA Safety Footwear - Implementing the Circular Business maps out several milestones in the transition of its business model, recycling logistics, supply-chain management and internal culture to make the circular shoe a sustainable business. A series of events between 2019 and May 2020 push the company in the right direction, but to be truly successful means taking the lead for the entire safety footwear industry, getting stakeholders such as customers, dealers, business partners, and competitors on board.

Corporations are increasingly held responsible for the products they source and the sustainability of their supply chains. It was to meet this need that EcoVadis, a sustainability rating agency, was founded in 2007 by Pierre-François Thaler (INSEAD MBA, 1999) and Frédéric Trinel to bridge the information gap between corporate buyers and their suppliers. Following an EcoVadis sustainability assessment, suppliers receive a "scorecard" of their performance which they can then share with clients, while corporate buyers can monitor suppliers' sustainability performance via the EcoVadis platform. The combination of technology, expertise and network effects propels the rating agency onto the global stage, with over 650 employees in 10 offices on 5 continents, and over 55,000 assessments completed. However, the co-founders need to adjust their strategy in an increasingly competitive and technologically sophisticated market. How can they scale up its human capital and technology capabilities to drive growth in the next decade, and ultimately make the corporate world more sustainable?
