WHAT IS CARBON FOOT PRINTING (CFP)?
GHG emission caused directly or indirectly by an
individual, event or product
Measure of environmental impact
Considers CO2 and GHG emissions
Unit: t CO2e
-
8/3/2019 1 CFP for Textile Industries Final Web
3/29
Accounts energy inputs and emission outputs
Limited to emissions effects on climate change
Consider life cycle assessment
APPROACHES
-

4/29
Organisational carbon foot print
deals with entire activities
Product carbon foot print (single product / activity /
service)
deals with life of product
All activities and products through the supply chain Considers right from production to until end use
TYPES OF CFP

INTRODUCTION
Textile industries are the biggest sources of GHGs
Clothing industry accounts for 4% of global CFP
>1 million tons of textiles are thrown away each year
They do not decompose quickly
Generate methane while decomposing (e.g. woolen
garments)

SIGNIFICANCE
Significant in entire processes from cotton growing to
until delivery to retailers and final disposal
Cotton cultivation practices chemicals & machineries,
Ginning electricity
Spinning humidification & other electrical applications
Wet processing heat & chemicals
Garment, carpet, woollen, jute - electricity & chemicals
Logistics to retailer transportation : fossil fuels
Ultimate Result global warming

GLOBAL IMPACT
For producing 60 billion kg of fabric every year 132 million metric tons of coal is burnt and
9 trillion litres of water is used
In 2009, first carbon foot print for textile and
related products were released in UK

CFP REDUCTION OPTIONS
Energy efficiency measures
Use ofrenewable energy
-
8/3/2019 1 CFP for Textile Industries Final Web
15/29
Spinning potential to reduce energy use by 10%
Water treatment potential to reduce about 20%
emissions reduction
Dyeing Some of the new technologies and organic
dyestuffs reduce emissions by about 20%
Finishing old machinery replacement and
elimination of diesel generators reduce emission by
15%
