Scientists agree that humanity must vastly reduce anthropogenic (human-caused) greenhouse gas emissions in order to avoid the worst effects of climate change. Most of these reductions will need to be made by companies changing their energy use and de-carbonizing production processes. Many these companies are in infrastructure sectors, with significant legacy capex, commodity margins, and they are often publicly listed. We need these companies to successfully transition, but the challenge is significant. In a system of private enterprise, this will only happen once companies find it in their interest to do so. The course will focus on how companies can find a business strategy for decarbonization, how they can create a financial model that will enable a decarbonization strategy, and what has to be aligned within an organization - both internally and with respect to investors - in order for this to succeed. We will adopt the lens of the executive team leading a firm. Government policy will be an important consideration, but we will be thinking of policy from the perspective of a firm to whom the policy applies, not from the perspective of the policy-maker. You should expect the course to be highly interactive. You know that climate is a hard problem and we do not have all the answers. The class will be built around some key cases drawn from energy-intensive commodity industries facing this challenge-steel, fertilizer, automobiles, oil and gas-and on the role of finance in relation to all of them. Together, we will try to develop frameworks and strategies to address these challenges.
