Case Studies of Good Businesses
Business case studies serve as examples of successfully implemented sustainable business models, which not only benefit the planet and the people but also lead to an increase in profit. To inspire and highlight how purpose-driven brands acquire a competitive advantage, we brought a couple of instances, broken down by category, based on The Guardian’s Sustainable Business Case Studies. They illustrate our core belief, how economic growth, social prosperity, and sustainability go hand in hand.
Communicating sustainability
To build the solar light market in rural Africa, SolarAid set up SunnyMoney, a social enterprise to develop a unique distribution model. They worked with headteachers, appointing them to promote the benefits of solar lights and the dangers of toxic kerosene, reaching the heart of communities in areas with weak transport and communication infrastructures.
Buying solar lights reduced the carbon footprint of people, saving each family money and allowing children to study an extra hour each day with the new lights. SolarAid can serve as a role model for future leaders, creating demand in a difficult environment, while also enabling people to live more sustainably. They achieved this through putting environmental and social objectives ahead of financial imperatives.
