Carbo Farm Calculator

Valio needed a tool that could take a serious carbon-accounting model and put it in the hands of dairy farmers who have never used anything like it. I was the only designer on the project, and we had about four months to go from nothing to launch.

The calculator now covers 1,900+ farms and 60% of Finland's milk production. It's Carbon Trust certified. I designed everything from the system tokens to the final screens, trying to make something scientifically rigorous feel simple enough that a farmer would actually use it.

The Problem

Carbon accounting for a farm is structurally messy. Emissions come from feed, herd composition, manure, energy, soil, transport, and machinery, each with different rules and dependencies. The underlying model was scientifically rigorous; the user needed a path through it that did not feel like accounting software.

There was no established category pattern to borrow from. This was a 0→1 product problem: build trust in the methodology while keeping the interaction model understandable for people whose job is running farms, not decoding climate frameworks.

My Role

Solo Lead Designer · ~4 months

I owned the end-to-end product surface: input architecture, screen design, the supporting design system, results views, and reporting outputs. I worked directly with Valio's sustainability specialists to understand the IPCC-based model well enough to decide where the complexity should stay visible and where the interface should absorb it.

That distinction mattered. The point was not to simplify the science. The point was to make a rigorous method legible, navigable, and useful in day-to-day decision-making.

Interaction Model

The first design task was structural: map every required input, understand the dependencies, then decide how much of that complexity the product should handle for the user. That produced a grouped input architecture organized around how farmers think about their operations rather than around the raw logic of the emissions model.

The product then used progressive disclosure to keep detailed sub-categories available without making the whole workflow feel like a wall of forms. The result layer translated the calculation outputs into a clearer picture of current footprint, reduction opportunity, and what to work on next.

Why It Landed

The credibility of the product came from two places working together: the methodological rigor behind the calculation and the interface clarity that let users engage with it confidently. That is the core design achievement here. Farmers did not need a simplified story. They needed a dependable one they could actually use.

The product's reach later made that clear. This was not a speculative prototype. It became part of a real national sustainability program operating across a large share of Finland's dairy supply chain.

The hardest part wasn't the interface. It was earning the trust of people who know carbon science far better than I do, and making something they'd actually endorse putting in front of farmers.
