Summary
The true impact of fluorinated compounds in the atmosphere. This project aims to improve the underpinning science that is incorporated into atmospheric chemistry models so humanity can better understand, predict and respond to the impact of emitting large volumes of fluorinated compounds. This project expects to challenge assumptions currently used to model the atmospheric chemistry of organic fluorine compounds, as well as to evaluate the environmental impact of replacements. Expected outcomes ....The true impact of fluorinated compounds in the atmosphere. This project aims to improve the underpinning science that is incorporated into atmospheric chemistry models so humanity can better understand, predict and respond to the impact of emitting large volumes of fluorinated compounds. This project expects to challenge assumptions currently used to model the atmospheric chemistry of organic fluorine compounds, as well as to evaluate the environmental impact of replacements. Expected outcomes include a general model of organic fluorine photochemistry and refined atmospheric chemistry models. This should provide significant benefits in that humanity can avoid an environmental disaster and new, environmentally benign products can be developed.Read moreRead less
The long-term impact of short-lived, fluorinated pollutants. In 1987, the Montreal Protocol has regulated the manufacture and use of compounds that deplete the ozone layer. Industry has innovated to produce new compounds that do not affect ozone levels, for use in refrigeration and other applications for modern society. We have discovered that the current generation of compounds called hydrofluoroolefins decompose in the atmosphere to produce the worst global warming gas known. We hypothesise th ....The long-term impact of short-lived, fluorinated pollutants. In 1987, the Montreal Protocol has regulated the manufacture and use of compounds that deplete the ozone layer. Industry has innovated to produce new compounds that do not affect ozone levels, for use in refrigeration and other applications for modern society. We have discovered that the current generation of compounds called hydrofluoroolefins decompose in the atmosphere to produce the worst global warming gas known. We hypothesise that other HFOs will also decay into global warming compounds. In this project we will determine the atmospheric consequences of modern refrigerants. Expected benefits include determination the best and worst compounds for environmental impact, and data to guide industry and legislators.Read moreRead less
