Global warming has been taking effect on the Earth’s environment since the 1950’s creating dramatic changes and dangerous new records. In the last three decades the Earth’s average surface temperature has each been successively warmer than any previous decade since 1850 as a result of increase greenhouse emissions (IPCC 2014). This temperature rise is impacting some of the most vulnerable ecosystems on the planet such as the polar regions, coral reefs and tropical rainforests. Climate change can also be connected to an increase in extreme weather events such as flooding from increased precipitation or glacier melting, drought, cyclones and hurricanes and fires (Tollefson, J 2015). To avoid these dangerous outcomes a multi-nation agreement to limit global warming to less than 2 degrees above pre-industrial levels was formed with the intent of working towards decarbonising the global economy (IPCC 2014). Moving towards a low carbon economy in Australia will include major technological transitions in many sectors, each holding both challenges and opportunities.

Extensive research into the world’s climate and monitoring of the atmospheres greenhouse gas concentrations has shown increasingly clear evidence that climate change is a result of anthropogenic emissions. Since 1880, the mean global surface temperature shows an overall heating of 0.85°C (IPCC 2014) while carbon dioxide has risen from pre-industrial levels of 320ppm to 400ppm today (nature). These rising temperatures…
