Energy use refers to the amount of energy required to produce goods and provide services. Fashion products put high demands on energy use throughout their whole life cycle. This starts with fiber production, manufacturing, distribution and retail, and continues through to domestic laundering and maintenance during use. At the stage of disposal, incineration, depositing in landfill, and recycling, all require a high energy input. All these processes rely mainly on non-renewable resources such as fossil fuels, which not only depletes natural resources but also causes further environmental damage by high CO2 and greenhouse gas (GHG) emissions. While considerable savings in energy use and emissions per unit have been achieved through research progress and technological innovation, these benefits are virtually lost because of the constantly escalating speed and volume of fashion production, consumption and waste generation.(1)
