The problem

Your biggest client just emailed: “We need your carbon data by Friday.”

You open the attachment. A 40-page questionnaire. Scope 1, Scope 2, Scope 3. GHG Protocol alignment. Emission factors. Year-on-year reduction targets. You have none of it.

Here's what happens when you don't have it:

AASB S2 mandatory climate reporting starts July 2026 for Group 2 entities — with director personal liability for false or misleading disclosures.

Large customers already need your emissions data to meet their own Scope 3 obligations. If you can't provide it, they'll find a supplier who can.

Without a system in place, producing your first carbon report takes weeks or months of manual work with spreadsheets and consultants charging $15,000+.

External assurance (audit) is required from year one — and spreadsheets won't survive an auditor's review.

The solution

Your compliance gap closes this afternoon.

Emisso is purpose-built for businesses that need to meet climate reporting requirements fast — without hiring consultants, wrestling with spreadsheets, or spending months on a framework you'll use once a year. Your first report is hours away, not months.

Your report is three steps away

No consultants. No spreadsheets. No six-figure software bills.

Still on the fence? Fair enough.

Here are the questions every first-time visitor asks — answered honestly.

My business only has 10 people. Do I need carbon reporting?
Even if your business isn't directly subject to AASB S2 reporting, your larger customers likely are — and they'll need your emissions data to meet their own Scope 3 obligations. Emisso is built specifically for businesses with 5 to 500 employees. Our free plan covers Scope 1 & 2 with one annual report, which is often all a small business needs to satisfy their first enterprise request.
Will enterprise clients actually accept an Emisso report?
Yes. Our reports are aligned with the GHG Protocol Corporate Standard — the same framework used by the vast majority of Fortune 500 companies. Every report includes methodology notes, emission factor references (DEFRA, EPA, NGA), data quality badges, and a full evidence bundle — the same standard enterprise procurement teams expect.
I know nothing about carbon accounting. Can I still use this?
That's exactly who we designed this for. You don't need to know what a Scope 3 Category 1 emission is — our guided wizard walks you through every step in plain language. If you can read an electricity bill and upload a CSV from your accounting software, you can produce a credible carbon report.
What if I'm already working with a consultant?
Emisso works great alongside a consultant — or as a replacement. Consulting engagements for a basic carbon footprint can run $15,000 or more, so having your own tool to manage data and produce reports can significantly reduce costs. Either way, you own your data and can produce reports independently.
Can I cancel anytime?
Yes, with one click from your account settings. No cancellation fees, no lock-in contracts, no awkward phone calls. If you're on the free plan, you keep access to Scope 1 & 2 and your existing reports forever — even if you never pay us a cent. We'd rather earn your business every month than trap you in a contract.
How is my data protected?
Your data is encrypted at rest and in transit. We never share, sell, or provide your data to third parties — full stop. You retain complete ownership of all data and reports, and you can export or delete everything at any time.

Your climate reporting deadline won't wait.

Your competitors are already reporting. The businesses that get audit-ready first protect their contracts, satisfy their customers, and avoid the last-minute scramble. Don't be the supplier who can't provide the data.
