Sustainability consulting is the field everyone wants to break into and few understand the door to — and the question underneath all the others is "how do I actually get in without it being a vague ESG job?" The real answers: it's a technical specialty layered on a design/engineering base, LEED AP is table stakes not a career, and the money is in energy modelling and hard building performance, not slideware.

Same credential, different money, depending on where you take it.
Energy modelling, decarbonization, embodied carbon, and measurable building performance — the technical work clients pay real money for and can't easily replace.
Best for: People with the engineering/building-science chops to go deep.
Every figure above is what sustainability consultants get paid. It is not what you charge once you run your own green-building consulting practice. Your rate has to carry the hours you are not on the tools, the truck, the tools themselves, WSIB, insurance, the quote you wrote and lost, and the holdback sitting in someone else's account for 60 days. Contractors who set their rate off their old hourly wage are the ones who work every weekend and still cannot say whether the year was profitable.
The step from paid by the hour to paid by the jobPrincipal, your own green-building practice, in-house sustainability leadership at a developer or corporation, or deeper into the technical specialties (building-envelope performance, energy modelling, embodied-carbon/LCA). As codes tighten toward net-zero and ESG reporting becomes mandatory, the trajectory is strongly upward — but it rewards the people who stayed technical over the ones who stayed general.
AEC Stack handles incorporation, insurance, proposals, invoicing, and chasing the money, so a green-building consulting practice runs with an office behind it from the first client.
