Case Study: Build a Dynamic Decarbonization Chart in Claude
Most sustainability charts have the same problem. They are built once, frozen immediately, and rebuilt every time something changes. The logic stays in your head. The file captures only one scenario. And the next stakeholder question sends you back to square one.
This workflow solves that permanently.
The case study: A decarbonization waterfall chart — one of the most common and most rebuilt charts in sustainability work. Base year emissions, a 2030 reduction target, business growth projections, and five reduction levers: efficiency, renewables, electrification, offsets, and certificates. Built once. Adjustable in real time.
What changes after this workflow: Instead of rebuilding the chart when your CFO changes the growth assumption from 6% to 8% — you open the link, move the slider, and show the updated gap live in the room. The decision gets documented. The screenshot goes back into the presentation. The rationale is traceable.
What you own at the end: A live chart. A documented prompt. A portfolio entry. Intellectual property that travels with you.
Who this is for: Any sustainability professional who has built the same chart more than once and lost the logic the moment the file was closed.
