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?

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?

The global population is expected to reach 9.6 billion by 2050, of which 70% will be living in cities. Over the past 40 years, however, 30% of the world's arable land has become unproductive. Given the scarcity of land and rising demand for food, there is an urgent need for solutions that require less land and labour yet produce higher yields. Vertical farming uses three-dimensional space to achieve more than a hundred-fold increase in crop production over traditional agriculture. However, such farms involve extremely high capital and operating costs. The case study reviews the the technologies on which vertical farms depend and the conditions under which they can become economically viable.
