r/sustainableFinance

Hi, i'm gonna take a degree in accounting/finance and actually i'm cery interested in green accounting/finance but i still struggle to understand how we know the environmental number's being reported are actually reliable.

Let's say if a project says it removed 10.000 tonnes of CO₂ of restored 5.000 hectares of land, what happend behind the scenes to come up with those numbers?

Is there a specific metric, methodology, or verification process that people in sustainbale finance usually look at first?

I'd be curious to hear approach this, especially when comparing differenet projects.
