Climate change is affecting all citizens on Earth; the bra manufacture sector should understand the problems and help reduce the impacts of climate change from the bra manufacturing. What is the carbon footprint of a bra and the opportunities to reduce its GHG emissions? Bra production mapping is aimed to find out the answers and initiate sustainable thinking and practice in bra design and manufacturing in China and Hong Kong. The objectives are to account and report the carbon footprint of a bra. This helps the bra-manufacturing sector to incorporate sustainable thinking into the decision making for suppliers, materials, product design and manufacturing processes, to take interesting challenges in adopting a low-carbon approach. The study may serve as a learning source for the participants along the life cycle of a bra. A padded moulded bra, the best selling product of a Chinese bra manufacturing company (unnamed), was selected for the calculation of the carbon footprint.

The project examined the life cycle of a padded moulded bra for the preliminary study. It helps to frame the knowledge of the impacts of the bra from the raw materials to the disposal, and to set goals and scopes for the carbon footprint assessment. The assessment accounted both direct and indirect emission sources from the production. The emission sources of the user phase and the disposal were not included.The objective is met with the exception of few uncertainties in the data, but the study can be a reference to implement more accurate GHG emissions accounting
and reporting in the future.

The results found out that the majority of the emissions are from the bra distribution and moulding process. The Bra industry
should focus on these areas for GHG reductions.
