University of Cambridge (CISL) · Online, United Kingdom
Unlike most things called a 'Cambridge certificate', this is a real University of Cambridge academic award: 60 CATS points at master's level — a third of a master's degree — earned fully online over about eleven months alongside a job. Part 1 is an open online course; Part 2 is selective, assessed and rigorous, and graduates can progress to CISL's Master of Studies in Sustainability Leadership. The strongest online credential in the corporate-sustainability field, priced accordingly.
