See the data behind the calculatorHow accurate is this?
It's a strong first estimate, built from your real activity, and honest about what's estimated. Good enough to open the conversation and to know where better data matters.
How the estimate worksWhat if someone is waiting on an answer?
If a customer, platform, or investor has asked you for emissions data, send us the request. We'll tell you what it actually needs before you commit to anything.
Send us the requestQuestions before you start
01Is it really free?
Yes. There's nothing to pay and no trial. We ask for your name and work email before showing full results, and that's it.
02Do I need to be a sustainability expert?
No. The questions are about your business: electricity bills, fuel, travel, spending. Every question explains where to find the answer, and "don't know" is always an option.
03How long does it take?
About ten minutes. Faster if you have your utility bills or spend numbers nearby; you can also estimate now and refine later.
04Can I give the result to my customer or investor?
Treat it as a first estimate, not a full assessment. The PDF is labeled accordingly and shows what would make it stronger. Before you answer whoever asked, collect the listed evidence, or send us the request and we'll tell you what it actually needs.
05What happens to my data?
We use your answers to calculate your result and to follow up about sustainability support. We don't publish them or share them with your customer. See our privacy policy.
