SUSTAINThe most rigorous sustainability audit we've seen applied to hospitality operations.
— Financial Times, Responsible Business 2025
“They saved our group $1.2M in year one.
The planet was a bonus.”
“Sustain doesn't sell green. They sell math.”
— Eater, "The New Kitchen Economics"

“I came in thinking this was an environmental exercise. Sustain came back with a spreadsheet that showed I was paying a disposal company $4,800 a month to haul away product I could have sold as staff meals, donated for a tax credit, or composted for a fraction of the cost. That conversation changed how I run my kitchen.”

“Our board wanted ESG metrics that would hold up in a due diligence process. Our previous reporting was basically a PR document. Sustain rebuilt it from the kitchen floor up — supplier audits, energy baselines, waste-stream accounting. When our Series C investors reviewed it, they called it the best they’d seen from a company our size.”

“Our investors don’t want greenwashing and neither do we. Sustain gave us a framework that survived legal review, third-party verification, and a journalist who spent three weeks trying to find a gap. There wasn’t one. That’s what accountability looks like.”
