Because they think all the ratepayers are stupid and will think that “low-emission Euro6 technology” is some fancy electric bus instead of the reality which is a DIESEL powered bus.

Council remains committed to delivering Australia’s most modern public and active transport. We have launched 10 new articulated buses which run on low-emission Euro6 technology and installed Speed Awareness Monitors across 100 locations, contributing to Brisbane’s reputation as a New World City.Graham Quirk, Lord Mayor February 2018 Living in Brisbane
