The term 'Carbon Footprint' has
become a topic of hot discussion all over the world. But what is carbon foot
print? It can be described as the extent of damage caused to the environment
due to some actions. It is the measure of severity of our activities on the
environment, especially on the climate change. Many of the activities in our
everyday life produce emissions, through the burning of fossil fuels for
electricity, heating etc. These activities have carbon footprint, producing
large amount of greenhouse gases, causing a disastrous effect on the
environment.
Greenhouse gases and global
warming:
Greenhouse gases are produced
by human activities, which result in global warming. Carbon-dioxide is a major
gas that accounts for almost 80% of the emissions. Burning of fossil fuels,
oil, natural gas, and petrol releases carbon-dioxide. Methane, nitrous oxide,
sulphur hexafluoride, perfluorocarbons etc are a few other greenhouse gases
originating from industrial processes. These gases accumulate and absorb infrared
radiation from the atmosphere, affecting the balance between energy received
from the sun and the energy that escapes.
Adverse Effects:
Due to these emissions, there is
a rise in the temperature. During the past 100 years, the earth's temperature has
risen on an average of 0.74 0.18C. It
is estimated that if the current scenario continues, by 2100 global temperature
may rise in the range of 1.4- 5.80C. This will result in floods in low coastal
areas, unpredictable and extreme weather changes with storms, drought, and
sudden wild fires. The ecosystem will be disturbed, and may put some species to
extinction. Vital diseases may spread across the globe.
Carbon Footprint of Textile
Industries:
Textile industry is chemically
intensive. From dyes to transfer agents, around 2000 different varieties of
chemicals are used in textile industries. Clothing industry is accountable for
4% of the carbon footprint developed in the world. More than 1 million tones of
textile are thrown away each year out of which 50 percent are recyclable. These
wastages need a landfill, and they do not decompose quickly. Woolen garments
while decomposing generate gases like methane which results in global warming.
Wet treatment of textiles like
desizing, prewashing, mercerizing, dyeing, printing etc includes a lot of
chemical applications on the fibres or fabric. Desizing of fabrics to remove
these chemicals releases large volume of residues in the water. Some fibres
need to be bleached with chlorine before dyeing. This causes organo-chlorine
compounds to be released, which are very dangerous to the environment. During
the process of wet treatment, huge quantity of fossil fuels are consumed, which
have carbon content and react with oxygen to form carbon-dioxide. This results
in acidification, fossil fuel depletion, and ultimately; global warming.
Creating a Carbon free
environment:
Mahatma Gandhi once said "one
must care about a world one will not see". It is every one's
responsibility to take care of the world, which we leave for the future
generations. Minimizing the emissions is vitally important in slowing and even
reversing the climate change.
