CO2 Emissions
= Population × (GDP/Population) × (Energy/GDP) × (CO2 /Energy) David Richardson Kyoto Protocol 2002 2005 x=1 x=0 % change? What can we do? CO2 Emission x:
1. GDP
2. GDP per capita
3. Forestation area
4. Total population
5. Population density
6. Electricity generation
7. Dummy: developing/underdeveloped/developed
8. % of secondary school education
9. 1997 emission,Carbon dioxide emissions (CO2)
10. Industries value added
y: CO2 Emission y=
B0+
B1(GDP)+
B2(GDP per capita)+
B3(Forest Area)+
B4(total population) +
B5(population density) +
B6(Electrical energy) +
B7(Dummy: least developed country) +
B8 Dummy: developing country) +
B9(% of secondary school education) +
B10(1997 CO2 emission) +
B11(Industries value added)
Counter- intuitive signs of parameters
Multi-collinearity Variance inflation factor(VIF)
Data Transformation 1. GDP * Electrical energy
2. GDP * % of secondary school education
3. Electrical energy * industrial production
4. 1997 CO2 * Production 1. Low P-value
2. Significant T
3. + beta that fits our hypothesis Most Significant X Variables y=0.062636+0.050244x
Signed countries: y=0.062636
Unsigned countries: y=0.11288
Conclusion Therefore... DSE2020E Group 2
Global Waming: CO2 Emission CO2 Emissions
= Population × (GDP/Population) × (Energy/GDP) × (CO2 /Energy)
