on Carbon Emissions in China During 1978-2008," Environmental Impact
Assessment Review, Vol. 36, pp. 1-8.

Description: Annual Carbon emmission (1000s of million-ton carbon),
population size (10^7), urbanization rate (%), working age population (%),
household size (person/hhold), and per capita expenditure (CNY).
Primary model fit (with many autocorrelation checks):
ln(carbon emission) = ln(b0) + b1*ln(Pop) +b2*ln(urbanization)
+b3*ln(working age pop) + b4*ln(hhold size) + b5*ln(pc expenditure)
Fit ridge regression model.
