TECHNOLOGICAL AND BIOLOGICAL MITIGATION POTENTIALS AND OPPORTUNITIES

major findings from the IPCC WG III contribution to the Third Assessment Report

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

USA

Former USSR

Japan

China



TRANSPORTATION IS A MAJOR CONCERN OCCURRED BUT NOT ENOUGH


Mitigation options OCCURRED BUT NOT ENOUGH

  • Energy efficiency

  • Decarbonisation

    • energy sources

    • CO2 removal and storage

  • Biological carbon sequestration

  • Reducing other greenhouse gases from industry, agriculture, waste management


GHG emissions per kilometer for different vehicle technologies

gCeq/km

Mitigation options technologies

  • Energy efficiency

  • Decarbonisation

    • energy sources

    • CO2 removal and storage

  • Biological carbon sequestration

  • Reducing other greenhouse gases from industry, agriculture, waste management


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


Mitigation options supply

  • Energy efficiency

  • Decarbonisation

    • energy sources

    • CO2 removal and storage

  • Biological carbon sequestration

  • Reducing other greenhouse gases from industry, agriculture, waste management


Carbon dioxide storage capacities supply

Emissions to be avoided: 300-1500 GtC up to 2100

Source: Moomaw et al, IPCC, 2001


Mitigation options supply

  • Energy efficiency

  • Decarbonisation

    • energy sources

    • CO2 removal and storage

  • Biological carbon sequestration

  • Reducing other greenhouse gases from industry, agriculture, waste management


Biological mitigation potential: 100GtC up to 2050 supply

Emissions to be avoided: 300-1500 GtC upto 2100


Mitigation options supply

  • Energy efficiency

  • Decarbonisation

    • energy sources

    • CO2 removal and storage

  • Biological carbon sequestration

  • Reducing other greenhouse gases from industry, agriculture, waste management


Mitigation potential till 2020(cost<$100/tC) supply

Compare to: 3,000-15,000 MtC/yr average to be avoided over 100 years

Source: Moomaw et al, IPCC, 2001


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


Conclusions emissions by 2010 and 2020 to levels below those in 2000

  • 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
