Frequently Asked Questions

If you don’t see your question listed, bring it to the demo. We're always happy to answer your queries.

Can I use Avarni alongside spreadsheets?

chevron down

Avarni is designed to enhance your existing sustainability consulting practices, not replace them. With the ability to export all results and reports directly to Excel, you can seamlessly incorporate Avarni's outputs into your existing manual workflows.

Is my client data secure with Avarni?

chevron down

Yes — Avarni handles some of your client’s most sensitive data, so we operate with the strictest security practices. We are SOC 2 complaint and you always own any data loaded onto Avarni, and can remove it whenever you like. For more info, check our Security page.

Can I see emission factors used by Avarni?

chevron down

Yes—without this capability, Avarni would be useless for audit purposes. All emission factor coefficients, details, and source links are visible in Avarni calculations.

How much does Avarni cost?

chevron down

Because you already know carbon accounting, we don’t have to provide much support to you (although we will be there when you do need us). This means that we can provide you with a discounted rate per client compared to our regular pricing. Contact us to get a custom quote.
