The original idea by our green party was a "1-2-3 Ticket" which means 365€ for one state, double for two states, and triple for all states (per year for all public transport).
They just renamed the "3" ticket to climate ticket when they introduced it, meanwhile work on "1" and "2" is still ongoing in some places afaik.
