  1. TECHNOLOGICAL AND BIOLOGICAL MITIGATION POTENTIALS AND OPPORTUNITIES major findings from the IPCC WG III contribution to the Third Assessment Report JOSÉ ROBERTO MOREIRA Biomass Users Network - Brazil CLA Chapter 3 WG III July 18, 2001

  2. NO SHORTAGE OF FOSSIL FUELS

  3. DECOUPLING BETWEEN ECONOMIC GROWTH AND C EMISSION HAS OCCURRED BUT NOT ENOUGH USA Former USSR Japan China

  4. DECOUPLING BETWEEN ECONOMIC GROWTH AND C EMISSION HAS OCCURRED BUT NOT ENOUGH

  5. TRANSPORTATION IS A MAJOR CONCERN

  6. Mitigation options • Energy efficiency • Decarbonisation • energy sources • CO2 removal and storage • Biological carbon sequestration • Reducing other greenhouse gases from industry, agriculture, waste management

  7. GHG emissions per kilometer for different vehicle technologies gCeq/km Source: Moomaw et al, IPCC, 2001

  8. Mitigation options • Energy efficiency • Decarbonisation • energy sources • CO2 removal and storage • Biological carbon sequestration • Reducing other greenhouse gases from industry, agriculture, waste management

  9. Long term technical potential renewable and nuclear energy supply 2100 Total Energy Demand for SRES scenario ranges 515-2737 EJ/yr Nuclear 77-4620 EJ/yr on average over 100 years

  10. Mitigation options • Energy efficiency • Decarbonisation • energy sources • CO2 removal and storage • Biological carbon sequestration • Reducing other greenhouse gases from industry, agriculture, waste management

  11. Carbon dioxide storage capacities Emissions to be avoided: 300-1500 GtC up to 2100 Source: Moomaw et al, IPCC, 2001

  12. Mitigation options • Energy efficiency • Decarbonisation • energy sources • CO2 removal and storage • Biological carbon sequestration • Reducing other greenhouse gases from industry, agriculture, waste management

  13. Biological mitigation potential: 100GtC up to 2050 Emissions to be avoided: 300-1500 GtC upto 2100

  14. Mitigation options • Energy efficiency • Decarbonisation • energy sources • CO2 removal and storage • Biological carbon sequestration • Reducing other greenhouse gases from industry, agriculture, waste management

  15. Mitigation potential till 2020(cost<$100/tC) Compare to: 3,000-15,000 MtC/yr average to be avoided over 100 years Source: Moomaw et al, IPCC, 2001

  16. Technology improvements have the potential to reduce emissions by 2010 and 2020 to levels below those in 2000 SRES Range Carbon Equivalent Emissions Technological Opportunities 2000 2010 2020

  17. Conclusions • Technologies are available in the short term to stop the growth of global GHG emissions • Technologies are available today to mitigate climate change in the long term • The real problem of controlling emissions is to overcome the many political, economic, social and behavioural barriers to implementing mitigation options
