Work/4/5/Case study

A carbon footprint calculator for single products, at ClimatePartner.

The list of Product Carbon Footprint calculations: totals at the top, then each product with its emissions, how they are split, its data quality and its status

One product’s calculation: its total footprint, the share of materials, logistics, production and packaging, its identifiers and production site, and the table of its materials

Uploading a data collection template: a drop zone for CSV, XML, JSON and XLSX files, and the six products found in the uploaded file — Upload a template

The panel for editing a product’s general details, open beside its calculation, with two fields marked as invalid — Edit the details

Brief

ClimatePartner helps companies calculate, reduce and communicate their emissions. The Product Carbon Footprint is a new product on that platform: it works out the emissions of one product from cradle to gate, across its materials, packaging, production and inbound logistics.

Outcome

We cut the time a Product Carbon Footprint calculation takes from weeks to minutes.

My part

As Staff Product Designer I led its design end to end: user research, concept, prototyping, testing and iteration, working closely with product managers and developers.

Decisions

Key decisions.

1/3

Every footprint says how sure it is

A calculation carries a data quality rating, from very low to very high, in the list and for every material inside it. No number stands without a word on how solid its data is.

Eight calculations in the list: how each one’s emissions are split, a data quality rating from very low to high, and a status from in data collection to validated

2/3

Many products in one upload

A data collection template can hold several products. It goes in as CSV, XML, JSON or XLSX, the products it contains are listed and ticked, and they are calculated together.

The upload page: the drop zone, and under it the uploaded file with its six products, each one ticked and marked as uploaded

3/3

Errors show where they are made

A product’s details are edited in a panel beside its calculation. A city that cannot be located or a postal code that is not valid is flagged in the form, and marked in red on the page behind it.

The products and figures on these screens are sample data.
