『Abstract
Electricity generation in China mainly depends on coal and its
products, which has led to the increase in CO2
emissions. This paper intends to analyze the current status of
CO2 emissions from electricity generation
in China during the period 1991-2009, and apply the logarithmic
mean Divisia index (LMDI) technique to find the nature of the
factors influencing the changes in CO2 emissions.
The main results as follows: (1) CO2 emission
from electricity generation has increased from 530.96 Mt in 1991
to 2393.92 Mt in 2009, following an annual growth rate of 8.72%.
Coal products is the main fuel type for thermal power generation,
which accounts for more than 90% CO2 emissions
from electricity generation. (2) This paper also presents CO2 emissions factor of electricity consumption,
which help calculate CO2 emission from final
electricity consumption. (3) In China, the economic activity effect
is the most important contributor to increase CO2
emissions from electricity generation, but the electricity generation
efficiency effect plays the dominant role in decreasing CO2 emissions.
