Petra Carbon Index, for Slattery.
Slattery host Australia's first Carbon Index Calculator. It lets a construction project estimate embodied carbon from verified Australian cost and construction data, early enough in the process to change a decision.
The brief was never "build a calculator". It was to work out what the index should measure, who it is for, and what it has to prove before anyone will use it to make a call. We ran product strategy, design and front-end engineering in a weekly cycle with Slattery's own team, shipping in slices rather than holding the work back for a single reveal.

Clicks and sessions are measured in different systems over different windows, so read them as scale rather than as a funnel. The product converts strongly once people reach it.
