George Serafeim is the Charles M. Williams Professor of Business Administration at Harvard Business School, where he co-leads the Climate and Sustainability Impact Lab in the Digital, Data, and Design Institute. He teaches the course "Risks, Opportunities and Investments in an Era of Climate Change" (ROICC) that he designed for the MBA program. With a focus on operating and business models, ROICC has three tracks, entrepreneurial, managerial and investment, for students developing skills to excel in creating or joining startups, moving to managerial positions, or joining an investment firm. It explores growing opportunities in energy transition (such as electric vehicles, heat pumps, off the grid solar energy systems, green hydrogen, renewable energy generation, and bioethanol for clean cooking), materials and product utilization (such as circular models for reuse or recycle, plant based food, and lab grown agriculture), and enabling solutions (such as energy storage, carbon capture and storage, digital and AI driven models, carbon accounting, carbon credits and markets, risk management, and innovative financing). Professor Serafeim co-chairs the executive education program Unlocking Growth with Climate Change Innovation and regularly teaches in the school's custom executive education programs for senior leaders of global companies.
