Report a bug

What is a bug?

Something that does not work as it should: a wrong or impossible result, a button or field that does nothing, an error message, text in the wrong language, or a printout or PDF that is broken.

• A result that contradicts the standard or source the tool refers to
• A page that does not load, freezes or shows raw codes
• Translations that are wrong or missing

What to include

Send an e-mail to Co2Calc@proton.me with the subject "Bug" and:

• which tool, which language and which country or standard you selected
• what you did, step by step, so we can repeat it
• what you expected and what was shown instead
• the saved project file (the Save button in the tool, a .json file) – it contains all your inputs
• screenshots of the problem, if possible
• browser and device (e.g. Chrome on Android, Safari on iPhone, Edge on Windows)

What happens next

Every report is read. Confirmed bugs are fixed in a coming update and listed in the changelog. We cannot give design advice for individual installations.
