Vera Wong, our consultant, has done an excellent job again This edition is the first time that these themes have been this year in preparing the Bulletin.

Environmental Indicators for Metropolitan Melbourne – Bulletin 7 3 AT A GLANCE – A SUMMARY OF WHAT’S BEEN HAPPENING The ‘Envirometer’ gives a snapshot of the key messages from the data presented. However it is not a quantitative measurement. Readers should not interpret the Envirometer in isolation from the detailed data and commentary provided. The committee has based the Envirometer ‘score’ on the condition of each issue presented. Air Emissions Motor Vehicles are the top source of pollution in the Port Phillip Airshed Region, accounting for 20% of all pollution. Chemical manufacturing was the next biggest source (14%), followed by domestic wood fires (5%). Petrol passenger vehicles accounted for the majority of motor vehicle emissions in Victoria (65% CO, 88% NH3, 42% NO and 71% VOC), except for particles. 60% of motor vehicle particle emissions were produced by diesel fuelled The Envirometer x Air emissions are improving, but motor vehicles.
