URBAN DEVELOPMENT The City of Carbon Neutrality It appears that the City of Churches is looking to pull off a miracle, with Adelaide Lord Mayor Martin Haese speaking at COP21 about the goal to make his city carbon neutral by 2025. The plan was officially announced in April, when the South Australian

Between 2007 and 2013, the City of Adelaide reduced its carbon emissions by 19%, while gross regional product increased by more than $4 million. According to Haese, this is proof that “the whole argument that you can’t grow your economy without increasing your greenhouse gas emissions has been decoupled”. This city-wide reduction can be attributed to largely the greening of the electricity supply — including large-scale wind and solar projects, rooftop solar photovoltaics — and further energy-efficiency

• a new waste strategy to reduce the city’s landfill by diverting 70% of metropolitan household waste by 2020; • an expression of interest calling on low-carbon energy providers to service 100% of the government’s electricity usage; • an additional $300,000 funding for three projects, creating new jobs in the state’s waste and recycling sector; • an ongoing investigation into the opportunities to convert the government’s 4500-strong car fleet to zero-emission vehicles. According to Haese, the plan could be just what’s needed to improve Adelaide’s ranking as the fifth most livable city in the world.

Greener, cooler cities The Cooperative Research Centre for Water Sensitive Cities (CRCWSC) has welcomed the federal government’s plan to make Australia’s cities greener and cooler. In a recent speech to the Sydney Business Chamber, Acting Cities

“Green cities — cities with high levels of trees, foliage and green spaces — provide enormous benefits to their residents,” Hunt said. “They can improve the quality of air in our cities by absorbing some types of airborne pollutants, reduce soil erosion, minimise water run-off and limit the amount of particulate matter entering our waterways; and increase urban amenity.”

CRCWSC urban climate researcher Professor Nigel Tapper, from Monash University, said there is strong evidence that a green, leafy park, tree-lined street or urban waterway could drop the local temperatures by several degrees. “This cooling is extremely important for reducing heat-related deaths, particularly during the very hot days of the year, which
