I Built an Emissions Calculator App in 8 Hours (With Zero Coding Skills)

Over the weekend, I built an entire Emissions Calculator app — dashboards, heat maps, Scope 1 & 2 reports — from scratch.
Total time: Less than 8 hours.
Coding experience: Zero.
And it cost me 0$.
Shocked? So was I.

During my master's thesis, I spent months digging deep into Scope 3 emissions — how to calculate them, how to help companies overcome the endless challenges along the way.
It was complicated then, and it’s still complicated today.

Back then, I tried to develop Excel templates for Scope 1, 2, and 3 emissions. But every change in the data meant hours of manual updates. Every dashboard, every highlight — all built manually, piece by piece.
It was tedious. It was slow. It was frustrating.

So I shelved the idea. Life moved on.

Fast forward to today — the era of AI, where every conversation seems to circle back to "how easy things have become."
I decided to revisit that old idea sitting in my drawer.
The surprise?

In just 8 hours, with zero coding experience, I built a functioning emissions calculator app.

A tool that:

• Reads Excel inputs

• Calculates full Scope 1 and 2 emissions

• Generates dynamic dashboards

• Creates a heat map showing hotspots

• Summarizes everything you need for reporting

It shocked me how easy it had become.

🎥 See It in Action:

I recorded a quick walkthrough showing how the app works — from uploading an Excel file to getting full Scope 1 and 2 calculations, dashboards, and a heatmap... all in just a few clicks.

Trust me, it’s worth a few minutes.

🔔 Why This Matters:
The gap between idea and execution is collapsing.
You don't need to know how to code.
You don't need months.
You need the right idea... and a willingness to explore.

If you're not experimenting with AI, no-code, and automation today, you're not just standing still — you're falling behind.

Imagine what you could build in just one weekend.

🛠️ How I Built It (Without Coding Experience):

While I had the domain knowledge — understanding Scope 1 and 2 emissions, calculations, and reporting requirements —
I had zero traditional coding experience to build an actual working app.
I had no idea how to program a backend, how to design a frontend, or how to build charts — none of it.

So how did I do it?

I used two tools:
