Based on recent electricity grid decarbonisation forecasts, facility emissions from grid electricity use could fall significantly by 2030. With further R&D around Industry 4.0 technologies for refrigeration energy efficiency, additional reductions in grid electricity emissions could occur. Other key technologies for decarbonisation have not changed significantly since the 2019 report, but heat pumps have become more available and competitive for hot water generation. There has also been rapid growth in the implementation of on-site solar PV systems.
The report recommends individual plants develop site-specific carbon footprints, to help build strategies for further decarbonisation opportunities. It also suggests companies with overseas partners or ownership should review emission reduction targets created by applicable international governments, as these targets may not align with the Australian government targets.
