Carbon Counting

2018

Freelance work from 2018, through Stephan Ye Design. The craft has moved on since. The problem hasn't.

CarbonCloud, led by food and climate researchers, helps producers and restaurants calculate the climate impact of what they serve. As a Product Designer, I spent 6 months turning customer research into a tool chefs could use daily and diners could trust.

Kitchens are unpredictable. Dishes change with what's in season, what sold out at lunch, what a supplier swapped in. Chefs needed to log climate impact as fast as they built the menu, not as a separate chore afterward.

The dish editor became mobile-first: add an ingredient, watch the CO2 estimate update, done. The same editor scaled up to a full week's planner on desktop, for the manager laying out the whole menu at once.

On the restaurant side, a dashboard turned that same data into something the business could act on, emissions, wasted portions, and revenue side by side.

Once a menu was set, it had to reach the people eating it. The web app translated each plan into printed menus and the guest-facing app, shareable via API, so a diner choosing between two dishes could see the climate difference before ordering.
