Measure your website’s carbon footprint for free

I’ve been diving deep into the hidden environmental cost of our digital lives lately. It’s easy to forget, but every kilobyte of data we transfer actually grid-powers a server somewhere, leaving a real-world footprint.

To help fix this, I just built a completely free Website Carbon Calculator: 1clickimpact.com/website-carbon

How it works : You just plug in your URL, and it analyzes the data transferred during a page load, factors in the energy intensity of the data centers, and checks if the host uses green energy. It takes about 5 seconds to give you a full breakdown.

The coolest part? Instead of just giving you a sad number and leaving it there, you can embed a small, clean badge into your site. It tracks your footprint in real-time and automatically offsets the impact as people browse.

(And if you want to bake this directly into your own products or dev workflows, I also exposed the endpoint as a simple API: docs.1clickimpact.com/website-carbon)

If you want to see how your site stacks up, test it out here: 1clickimpact.com/website-carbon

I'd love to know your scores and if you find any surprisingly heavy assets slowing things down!
