The Correlation Between WIP and Emissions

World Industrial Product (deflated world `GDP' in real value - i.e. World physical production).

CO2 emissions (in CO2 mass units: Doubling time = 29 years. Data: CDIAC; statistics: GDI.

The correlation between the WIP and the CO2 emissions is still however very high.

Efficiency Limitations to Emissions Reduction

Per capita emissions reduction through Pilzer 1st law substitution(Technology change = resource use change)

Rate of Per Capita Emissions Reduction

The Future2008

Per capita emissions reduction through thermodynamic efficiency

Total per capita emissions reduction

Conclusion: It is essential that R& D into substitution technologies occurs now in order to ramp up Pilzer first law substitution later and avoid thermodynamic constraints. This is not happening in Australia

Affect of Leakage on Geosequestration

Source: CANA (2004). Carbon Leakage and Geosequestration, Climate Action Network Australia.

"The assumption of exclusive reliance on storage may be an extreme one, however the example illustrates that emphasis on energy efficiency and increased reliance on renewable energy must be priority areas for greenhouse gas mitigation. The higher the expected leakage rate and the larger the uncertainty, the less attractive geosequestration is compared to other mitigation alternatives such as shifting to renewable energy sources, and improved efficiency in production and consumption of energy."
