How GreenScore Works

Your GreenScore is calculated by using data science to process the transactions you make on your Zero personal account and card. We have partnered with Doconomy to provide an estimate of the carbon impact of each transaction.

If you link your Zero account to your other bank accounts using our open banking feature, we will also process the transactions in those other accounts to give you a more accurate GreenScore.

We will seek your consent to process any additional data before we use it.

If you have more questions about GreenScore, there is some more information in the GreenScore section of our FAQs.
