CFC ban helped avoid scorched earth scenario
A new study from Lancaster University in the UK has revealed that continued deterioration of the Earth’s ozone layer could have had catastrophic effects on our planet, exacerbating global warming and impacting all plants and animals. The work also reinforces the importance and success of the Montreal Protocol, which phased out ozone-destroying CFCs with the […]

Reflective roads paving the way to cooler cities
Researchers in MIT’s Concrete Sustainability Hub have been modelling lighter-coloured and more reflective roads in a bid to lower air temperatures. Dark asphalt is known to raise the surrounding air temperature. Approximately 40 per cent of urban areas are paved, and by absorbing and reflecting heat it can increase the urban heat island effect. The researchers believe […]

Exposing hidden emissions in embodied carbon
A new report warns that embodied carbon could become a primary source of built environment emissions unless Australia acts now. Embodied Carbon & Embodied Energy in Australia’s Buildings was developed by the GBCA and thinkstep-anz with support from the Australian Government’s Department of Industry, Science, Energy and Resources. It says that without action, embodied carbon […]

Shape-memory alloy could replace HFCs
A small company in Ireland has developed a new type of air conditioning system that could negate the need for hydrofluorocarbons (HFCs). Researchers at Exergyn, based in Dublin, worked in secret collaboration with another company – believed to be Carrier – for two years on the project. The system uses a shape-memory alloy (SMA) called […]

Improving refrigerant recovery from split systems
A new report from Refrigerant Reclaim Australia (RRA) has highlighted the concerning volume of refrigerant lost when split systems reach end of life in Australia. It estimates that each year, hundreds of tonnes of refrigerant are not being reclaimed. Factoring in the global warming potential of the gases, this could equate to more than a […]
