Greenhouse gases naturally blanket the Earth and keep it about 33 degrees Celsius warmer than it would be without these gases in the atmosphere. This is called the Greenhouse Effect.
The greenhouse effect is important. Without the greenhouse effect, the Earth would not be warm enough for humans to live. But if the greenhouse effect becomes stronger, it could make the Earth warmer than usual. Even a little extra warming may cause problems for humans, plants, and animals.
A carbon footprint is a “measure of the impact human activities have on the environment in terms of the amount of greenhouse gases produced in our day-to-day lives through burning fossil fuels for electricity, heating and transportation.
The carbon footprint is a measurement of all greenhouse gases we individually produce and has units of tonnes (or kg) of carbon dioxide equivalent.
All electric power for Caterpillar’s FG Wilson manufacturing plants in Northern Ireland is supplied by Airtricity, a renewable electricity that develops and owns onshore and offshore wind farms.
This is Caterpillar’s first production site to be 100 % supplied by renewable electricity. The companies say the facilities will reduce CO2 emissions by approximately 11,000 tons per year.
Wind power is the conversion of wind energy into a useful form, such as electricity, using wind turbines.
Although wind currently produces about 1% of world-wide electricity use,it accounts for approximately 19% of electricity production in Denmark, 9% in Spain and Portugal, and 6% in Germany and the Republic of Ireland (2007 data).
South Korea announced plans to cap greenhouse gas emissions at 2005 levels for the next five years, despite South Korea not required to make cuts under the Kyoto protocol.
In a policy report to President Lee Myung-bak, Environment Minister Lee Maan-ee presented the ministry’s initiative to contain emissions of carbon dioxide, the main greenhouse gas, at 2005 levels.
