Description: Textile production is one of the most polluting industries, producing 3.29 billion tonnes (6.7%) of CO2 equivalent (CO2eq) per year (2016), which is more emissions than international flights and maritime shipping combined. The current review was conducted using two different approaches: in the first approach, the different combinations of textiles and garment manufacturing processes were investigated that can be used to make an apparel product. It was found that to produce a 100% weft knit cotton (carded) garment, a total of 48 processing steps are required, while to produce such garment using same fabric manufacturing process from 100% polyester dope dyed flat filament yarn (D2F2Y), only 18 processing steps are required. In the second approach, the greenhouse gas emission was tabulated for each textile processing steps. It was discovered that while to produce a 100% cotton T-shirt (250 gram) with standard textile specifications, 3.65 kg CO2 is emitted that includes cotton fibre cultivation (1.82), fibre to yarn transformation (0.96), yarn to fabric transformation (0.16), wet processing (0.63) and garment formation (0.08). However, if garments are produced from D2F2Y, two major polluting processing steps such as fibre to yarn transformation and wet processing are no longer required. The findings of the current review may be surprising; however, understanding textile processing is the first steps for individuals to contribute in reducing greenhouse gas emission.
