Best would be a software, where event organizers type in all the data and they automatically can apply for a "green event certification": eg in Austria it is handled like this:
https://www.umweltzeichen.at/file/Richtlinie/UZ%2062/Long/UZ%2062%20Green%20Meetings%20und%20Green%20Events%202022-1.pdf

Green event checklist example:
https://infothek.greenevents.at/upload/file/Checkliste_Green_Events_Austria.pdf

Goal is to implement all that data and get results automatically as:
Event Carbon Footprint report
etc
