Melbourne has reduced and offset its emissions to become a certified carbon-neutral city under Australia’s National Carbon Offset Standard (NCOS). The city has also launched several programmes to reduce its energy consumption and emission production as part of the Net Zero Emissions strategy.
- Commercial sector; Reduce emissions by 25% from business-as-usual levels by 2020
- Residential sector; Cut emissions by 20% by 2020
- Transport: 20% reduction in emissions from public transport by 2020, 15% emission reduction from cars and 100% increase in use of bicycles
- Power sector; 19% emission reduction from energy production by 2020
The city council has helped several businesses and buildings improve their energy efficiency and has also conducted energy audits of 12,000 homes across the city. Clean transport has been encouraged through innovative programmes like the Cycle Melbourne scheme. Small-scale solar power generation to reduce dependence on fossil fuels have also been encouraged.
While the city is believed to have achieved significant emission reductions from these measures, it is believed to have offset its emissions through the NCOS, Australia’s voluntary carbon offset scheme.
“The NCOS Carbon Neutral Program, administered by Low Carbon Australia, allows Australian organisations, products and events to be certified as carbon neutral,” they write on their website. “This means that net associated emissions are equal to zero. Consumers can have confidence that organisations, products and events bearing the NCOS trademark have achieved carbon neutrality in a way that achieves a genuine reduction in overall emissions.”
The centre-piece of the city council’s sustainability efforts is the Council House 2 (CH2). A plethora of measures have been implemented in this building to reduce energy consumption, waste generation and enhance captive power generation.
The building has a cogeneration plant which generates 30% of its total power demand. The waste heat generated from this plant is used for air-conditioning. The building is also fitted with a small 3.5 kW solar photovoltaic system and elevators that generate electricity while braking. Hot water is provided through solar water heaters. The building purchases 100% accredited green power.
The western facade of the building features recycled timber shutters. These shutters close with varying speeds during summer and winter to optimise the inside temperature and allow natural light to enter the building. The building is equipped with several water conservation and recycling equipment as well. These include sewer mining, re-use of fire sprinkler test water, and rainwater harvesting.
Low Carbon Australia certified the city for achieving the carbon neutral status. Low Carbon Australia’s CEO Meg McDonald, while congratulating the city council, said;
Global leading cities like City of Melbourne are responsible for an extraordinary range of economic activities and services and are critical to our move to a low carbon future. Quantifying the carbon footprint of such an organisation and reducing carbon emissions is a mammoth task, but one that can have substantial benefits for the environment, the city and for ratepayers. Councils taking this type of leadership position are important in showing the way in their communities for a prosperous low carbon future.
