## Before you start

### Are these really free?

Yes. Nothing on this page costs anything. Most of it needs no account. The few that do are marked "Free, sign-in". The green loan check and the sample ESG report ask for your email.

### Do you keep the bill I upload without an account?

No. Without an account nothing is stored on our side. The result stays in your browser for 24 hours. Sign in if you want to keep it as a record.

### Is a free check the same as an accredited verification?

No. The free tools give you an estimate or a record built from your own bills. Accredited verification is done by an independent verifier, and carbon credits are issued by a registry.

### Where should I start?

If a buyer or bank asked for your carbon footprint, upload one electricity bill. If you export steel, aluminium, cement or fertiliser to the EU, start with the CBAM cost calculator.

Start with one electricity bill: [upload it](https://senseible.earth/) and see the CO2 and the factor behind it. No account needed.
