The Clean Energy and Sustainability (CES) Program now offers workforce training in clean energy and sustainability at both undergraduate and graduate levels. The CES graduate certificate comprises four courses, including an internship/practicum component. Clean energy is one of the fastest growing sectors globally, according to Clean Edge, and Massachusetts is in the forefront of this trend. Markets and career opportunities are also growing rapidly in energy efficiency, smart grid, carbon trading, and related financial and professional services. In business, managers in every sector and every function, from operations and marketing to accounting and finance need to become knowledgeable about sustainability management and reporting. Similarly, this topic is increasingly important for people working in government, education, and nonprofit organizations.
