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

Technology improvements have the potential to reduce emissions by 2010 and 2020 to levels below
those in 2000
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
