  1. On Global Climate Change and Greenhouse Gases 2009 Summit

  2. Proposal • Acceptance of wedges to best meet United States goals on climate change and GHG emissions • Acceptance of national and international CDMs

  3. Current Situation • If we follow a “business as usual policy” we would have: • Rising global temperatures • Rising atmospheric CO2 levels and emissions • Rising sea levels • Decreasing global ice mass • Decreasing stratospheric ozone levels

  4. Wedges • Wedges are strategies to reduce carbon emissions zero to 1 GtC/year in 50 years • Main goal of wedges is to stabilize carbon emissions in 50 years so it would be the same as levels today • For example, if 8 wedges were implemented, we would have 8 less gigatons of carbon emitted per year in 50 years

  5. Wedges Easier CO2 target Billions of Tons Carbon Emitted per Year 16 ~850 ppm Stabilization Triangle Interim Goal Historical emissions 8 Flat path Tougher CO2 target ~500 ppm 1.6 0 1950 2000 2050 2100

  6. Wedges Billions of Tons Carbon Emitted per Year 16 GtC/y 16 Eight “wedges” Goal: In 50 years, same global emissions as today Historical emissions 8 Flat path 1.6 0 1950 2000 2050 2100

  7. Possible Wedges for the US • Double the fuel efficiency of US cars • Double the efficiency of US electricity production • Increase energy efficiency in commercial and private buildings • Install 1 million 2 MW windmills to replace coal based electricity • Implement carbon capture and storage (CCS) at 800 GW coal electric plants • Implement CCS at 1600 GW natural gas electric plants • Implement CCS at 180 coal synfuels plants • Triple Nuclear Power production and efficiency

  8. Additional possible wedges • Install 20,000 km2 of solar panels for dedicated use • Increase the capacity of hydrogen plants tenfold • * All proposed wedges are to be implemented in no more than 50 years for it to be effective

  9. CDMs • CDM – Clean Development Mechanism provided by the Kyoto Protocol • Designed to promote environmentally friendly technologies and sustainable development especially for Annex B countries • Allows GHG emissions to be reduced at a lower cost by financing projects in developing countries rather in industrialized countries

  10. CDMs in the US and North America • Our main goals in developing countries are to: • Utilize CO2 capture and storage strategies • Improve our pollution control • Invest more in alternative energy solutions and lessen our reliance on fossil fuels

  11. CDMs in the US and North America • Generate less unclean amounts of energy such as coal and fossil fuels • Regulation and control of numerous mining industries and their pollution • Establish logging forests and plant others • Develop more public transportation systems

  12. International CDMs • Hybridization of vehicles • Establishment of alternative energy sources to replace coal and fossil fuels • Reforestation • Conservation tillage • CO2 sequestration • Increased composting projects • Better pollution control and regulation

  13. Temperature Projections (Normal) + 2.47 degrees C (Transportation fuel efficiency wedge) + 2.29 degrees C (Nuclear efficiency wedge) + 2.28 degrees C

  14. Atmospheric Carbon Projections (Normal) + 1404.99 Billion Metric Tons (Transportation fuel efficiency wedge) + 1343.07 Billion Metric Tons (Nuclear efficiency wedge) + 1340.15 Billion Metric Tons
