From the field
The same lessons come up again and again from people actually doing the job:
People assume sustainability is a feel-good job for environmentalists. It's actually one of the most data-heavy, strategic roles in the business — I measure carbon, drive change across departments, and answer to regulators. It's serious work.

When I started, this was a nice-to-have. Now ESG disclosure is mandatory, investors demand it, and there's a seat at the board. The field exploded, and the demand for skills is enormous.

The hardest part is driving change when you don't run the departments — you have to win people over with data and persuasion. But seeing a company genuinely cut its impact, and prove it, makes it worth it.
