At Accountex earlier this month I was reminded of some software called Ecologi which links to Xero and can analyse your spend to identify your environmental impact and potential savings.
If you’re aiming to be a net zero business then it’s a useful tool in helping to focus on the high usage areas. You can also use the website to plant trees to offset the carbon that you do use.
So far it only links to Xero but I would expect to see them expanding to QBO then perhaps other bookkeeping software.
