CARBON FOOTPRINTS IN
WHAT IS CARBON FOOTPRINT
The total sets of greenhouse gas emissions caused by
an organization, event, product or person.
Wright, Kemp, and Williams, writing in the
journal Carbon Management, have suggested a
more practicable definition:
A measure of the total amount of carbon
dioxide (CO2) and methane (CH4) emissions of a
defined population, system or activity, considering
all relevant sources, sinks and storage within the
spatial and temporal boundary of the population,
system or activity of interest. Calculated as carbon
dioxide equivalent (CO2e) using the relevant 100year global warming potential (GWP100)
WHY IT IS NECESSARY
Climate changes characterized as global warming are
leading to large-scale irreversible effects at
continental and global scales.
TODAY CARBON FOOTPRINT = GLOBAL WARMING
LAYERS OF CARBON FOOTPRINTS
Primary footprint - monitors carbon emission
directly through energy consumption - burning fossil
fuels for electricity, heating and transportation, etc.
Secondary footprint- relates to indirect carbon
emissions (Life cycle of products and Sustainability).
HOW TO CALCULATE CARBON
Calculation of carbon foot prints totally depends on
type of energy used types of natural resources and
size of any organization.
NEED OF CARBON FOOTPRINT AUDIT IN
The Textile Industry in India is expected to grow
from an estimated size of US$ 70 billion today to
US$ 220 billion by 2020, which would
proportionately increase impact on our Carbon
In 2008, annual global textile production was estimated at
60 billion kg of fabric. The estimated energy and water
needed to produce such quantity of fabric is considered to
1,074 bn kWh of electricity
132 mn MT of coal.
about 6-9 tn liters of water.
Thus, the thermal energy required per
metre of cloth is 4,500 - 5,500 Kcal and the electrical
energy required per metre of cloth is 0.45 - 0.55 kwh.
APPROACH TO REDUCE CARBON FOOTPRINT
Substituting Organic fibres for conventionally grown
Modern machines and equipments helps to reduce
Optimize process sequence
Usage of chemicals and dyes
Waste water treatment
WAYS TO REDUCE CARBON FOOTPRINTS IN
Use of metals such as chrome, cadmium, lead, nickel and other heavy
metal residues are considered unfriendly to the environment, since
these metals release residues that are harmful to the human skin.
Recycling of small pieces of waste fabrics into shoddy items and/or
wipe clothes in the unit.
Co-ordination between design and production department
Biodegradable materials should be preferred against synthetic
CAD and CAM systems can be used to gain optimum fabric utilization.
Suggestions for general resource usage
Car pool system or keeping office vans for certain
routes can be set up for work.
Keeping tyres properly inflated increases the
efficiency of fuel. Turning off the vehicle’s engine at
red light saves 20% of the fuel.
Avoid large number of flights as air transportation
has a largest carbon footprint than any other means.
Prefer making conference calls.
Dimmer switches which reduce energy consumption
by up to 20% can be installed.
In the present times when global warming is a major
issue worldwide, it is our responsibility reduce our
contribution to carbon footprints. Besides reducing
waste and consequent reductions in air and land
pollution, it will lead to number of individualized
benefits. It will allow textile industry to demonstrate
their commitment to reducing their negative impact
on the climate and the planet.
