We use these names only to describe the exam this study aid is designed for (nominative use). Other product and organization names are the property of their respective owners.
Estimates and environmental claims
The Scope 2 estimator and other tools give planning estimates from the inputs and factors you provide. They are not a verified greenhouse gas inventory, an audit, a guarantee of savings or a claim that any facility has reached net zero.
No guarantee
The app is a study aid and does not guarantee an exam result. Site guidance is general and is not engineering, legal or medical advice. Validate decisions with qualified professionals, applicable codes and local regulations.
