Over the last 30 years, Greenland’s melt zone has expanded by 30 percent, and now the cap loses 100 to 150 cubic km of ice every year - more than all the ice in the Alps (Reuters.com)

A total melting of Greenland’s ice sheet would raise sea levels by seven meters (23 feet), threatening to submerge cities located at sea level, such as London and LA (national geographic, 2004)

Global Warming is not a theory, it is a FACT

The worrisome trend; continuous rise of global temperature

According to the National Academy of Sciences, the Earth's surface temperature has risen by

about 1 degree Fahrenheit in the past century, with accelerated warming during the past two

decades. There is new and stronger evidence that most of the warming over the last 50 years

is attributable to human activities. (source:US-EPA)

Who are the main culprits?

Economically less active continents such as Africa are nearly non-existent, whereas the US

and China are culprits of nearly 50% of the world’s GHG emissions

According to Wikipedia, South Korea is the #9 nation in terms of green house gas emissions

South Korea

The IT industry accounts for 2% of global CO2 emissions

IT related CO2 emissions are rising 5.5 times faster than global CO2 emission levels

What is Green IT?

CO2 reductionthrough smart

convergence of ITwith non-IT related

industries

CO2 reductionof infrastructure

and corporate activitiesinside the IT industry

Green of IT Green by IT

Green IT covers all activities on“Green of IT” & “Green by IT”

‘Green of IT’ reduces the burden of IT on the environment while ‘Green by IT’reduces the burden through the use of IT

The Asian Green IT business is expected to grow58% on average per annum

Multipoint video conferencing services reduces CO2 emissions by 96.6% compared to traditional business

trips. The Korean video conferencing market has an annual growth rate of 20%, 7% higher than the global

average CAGR

If KT substitutes 10% of its traditional meetings with video conferencing, 2.2 billion wons worth of cost can

be saved and used for other areas. This equals to 250 thousand tons in carbon dioxide reduction annually
