Cold Call Harvard Business Review

Özyeğin Social Investments was founded by Hüsnü Özyeğin, one of Turkey's most successful entrepreneurs, with a focus on education, health, gender equality, rural development, and disaster relief in Turkey. Harvard Business School senior lecturer Christina Wing and Murat Özyeğin (MBA 2003) discuss how the company is a model for making a significant impact across multiple sectors of society through giving and how that legacy can be sustained in the future.

In the spring of 2021, Raymond Jefferson (MBA 2000) applied for a job in President Joseph Biden’s administration. Ten years earlier, false allegations had been used to force him to resign from his prior U.S. government position as assistant secretary of labor for veterans’ employment and training in the U.S. Department of Labor. Jefferson filed a federal lawsuit against the U.S. government to clear his name and used his entire life savings to pursue the case for eight years. Why, after such a traumatic and humiliating experience, would Jefferson want to work in government again?

Harvard Business School professor Frances Frei and Paul English, one of the most imaginative and successful innovators of his generation, discuss how to tell the difference between a good idea and a bad one, the importance of iteration, and taking a systematic (but fast) approach to developing new ideas.

Harvard University aims to be fossil-fuel neutral by 2026 and totally free of fossil fuels by 2050. As part of this goal, the university is trying to decarbonize its supply chain and considers replacing cement with a low-carbon substitute called Pozzotive®, made with post-consumer recycled glass. Harvard Business School professor emeritus Robert Kaplan and assistant professor Shirley Lu discuss the flow of emissions along the supply chain of Harvard University’s construction projects, the different methods of measuring carbon emissions, including the E-liability approach, and the opportunity to leverage blockchain technology to facilitate the flow of comparable and reliable emissions information.

In 2015, Apple debuted the iPhone 6S, which employed a default encryption system preventing both Apple and government authorities from accessing data stored on the device. But since then, global governments have questioned whether Apple’s desire to protect customer privacy interferes with public health and safety. Harvard Business School senior lecturer Henry McGee and professor Nien-hê Hsieh discuss how Apple CEO Tim Cook manages this tension.

Ethanol had already transformed Brazil, where flex-fuel vehicles dominated the streets. Raízen, a bioenergy company headquartered in São Paulo, sought to prove that second-generation ethanol (E2G) could do the same for the world – especially in hard to decarbonize sectors, such as aviation and shipping. E2G is made from a byproduct of sugarcane that doesn’t compete with food production, Paula Kovarsky, Raízen’s chief strategy and sustainability officer, was confident the company could become a global green energy champion. But she faced a complex challenge: how to expand the market for second-generation ethanol and other sugar-cane waste biofuels, in order to ensure Raízen’s long-term growth.
