Most full-time MBAs are graduating with a mountain of debt and are counting on a big salary bump in their post-MBA careers. Many MBAs working in sustainability careers do make less than their peers, but not necessarily for the reasons MBA students would expect. Salary has more to do with the organization than the job function. As a general rule, big companies hire more MBAs and pay more in starting salaries than small companies, startup ventures, and nonprofit organizations. As many MBA alumni will attest, the reward of doing a job they love at an organization they are completely committed to is worth more than money. Some individuals thrive in entrepreneurial environments, others need the structure of a big company or the mission-oriented nature of a nonprofit. Spend MBA students time finding the right role for they at the right organization for them.
