The global economy is undergoing a fundamental transformation to low-carbon technologies from electric vehicles becoming mainstream and large-scale solar, wind, and even battery installations. Many countries and companies understand that this fourth industrial revolution will change everything, and face risks as well as opportunities. Some countries are establishing policies that decarbonize their economy to avoid the worst effects of a 2 degrees Celsius rise in temperatures. Organizations should start to develop and implement a 2 degrees Celsius strategy by clearly understanding their exposure to climate-related risks and identifying best practices for adapting to new carbon regulation, along with transforming their businesses by deploying sustainable energy practices. Understanding greenhouse gas (GHG) emissions, including how to calculate them and the importance of reporting them publicly, is vital to understanding how to identify sources of emission and how to reduce them. This course teaches students how to measure, report, and reduce GHG emissions with an eye toward understanding the roles that energy choices and usage play in reducing emissions.
