Mobile phones, also called cell phones, have become daily
necessities of adults and children nowadays, though they were once
luxury items over two decades ago. According to statistics published
by the Office of the Government Chief Information Officer, cell
phone ownership has reached 152% in 2007, meaning each Hong Kong
resident has an average of 1.5 cell phones. A scene that we encountered
inside the MTR compartment where everyone in a row of six was holding
different latest model of cell phones, while only one person was
actually communicating, the rest were either surfing the internet
or playing games. Everyone with the head buried in cell phone seems
inevitable in digital era, while no cell phone in hand seems a shame.
The huge cell phone market enables rapid innovations. From the first
generation used only for communicating, to ˇ§smart phoneˇ¨ now integrates
different functions of photo-taking, music-playing, internet-surfing,
and so forth. Cell phone producers keep launching new models, generating
a trend like fashion and accessories, and tempting users to replace
their phones frequently to gain more profits. A study conducted
by Friends of the Earth (HK) earlier revealed that teenagers change
their personal cell phones in less than 20 months on average, i.e.
600 days. Within the year end of 2008 to October 2009, the market
has launched over 60 new cell phone models, which equals to incredibly
6 models per month on average!
A research pointed out that nearly 80% of CO2
emissions from cell phones come from the manufacturing process.
In other words, changing cell phones frequently will indirectly
increase greenhouse gas emissions and exacerbate climate change.
According to a worldwide statistic, it reached 4.6 billion cellular
subscriptions by the end of 2009 globally. Producing each cell phone
emits 16 kg of CO2, it implies a release
of 73 million tonnes of CO2, equivalent to
taking 54 million round-trip flights from Hong Kong to London!
Using cell phones also emits CO2 because
of energy consumption in cell phone communication facilities such
as receiving stations. A report revealed that calling with cell
phone for one minute produces 0.057 kg CO2,
which means 1,250 kg of CO2 will be emitted
in a year if one cell phone is used one hour per day.
In view of the advancing mobile communication technology, ˇ§smart
phoneˇ¨ starts to gain popularity, which is predicted to trigger
more CO2 emission directly and indirectly.
Itˇ¦s no doubt that cell phones have contributions to our lives,
but as a responsible consumer who cares for the environment, we
should avoid blindly pursuing the new models whenever they launch.
Choose a cell phone with functions that suit your needs, and try
to prolong its life-span by not changing new model frequently, it
does not only help reducing electronic waste, but also benefits
in alleviating climate change.
Nowadays, social media is so popular that many cell phones are equipped
with internet functions, allowing users to communicate with friends
and share information on the internet at anytime. Network service
providing is essential, yet it is one of the main contributor of
CO2 emissions. We will further discuss this
topic in the next e-Bulletin.
