The Carbon Dioxide Information Analysis The Carbon Dioxide Information Analysis Center (Center (CDIACCDIAC) and the United Nations ) and the United Nations Framework Convention on Climate Framework Convention on Climate Change (Change (UNFCCCUNFCCC). ).
For the present investigation the data set For the present investigation the data set provided by the CDIAC is used because it provided by the CDIAC is used because it gives data sets for a larger number of gives data sets for a larger number of countries / areas as compared with the countries / areas as compared with the UNFCCC.

TREND ANALYSIS OF CARBON DIOXIDE EMISSION …
For understanding the trends of the carbon dioxide emissions a linear trend equation based on the last ten years data is obtained for each country / area.
The investigation is based on the data of 1998 to 2007.
1010
TREND ANALYSIS OF CARBON DIOXIDE EMISSION …
The assumption of linear trend is justified because of smaller number of observations.
This assumption appears to be more reasonable for understanding the annual growth rate.
1111
TREND ANALYSIS OF CARBON DIOXIDE EMISSION …
Out of the two hundred nine thirty four countries / areas (16.3%) reveal negative annual growth rates (showing decreasing emission).
The linear trend equations disclose that China has the highest annual growth rate (394016) while Germany has its lowest value (-7488).
1212
TREND ANALYSIS OF CARBON DIOXIDE EMISSION …
This shows that the emission over the years has decreased in Germany.
The descriptive statistics of the two countries are obtained.
