Global Warming - Mitigations Low carbon green growth economy Energy efficiency, conservation efforts Introduce carbon tax system UN climate change initiatives Kyoto Protocol expires in 2012 New Protocol in Copenhagen, Dec. 2009

Copenhagen Protocol UNFCCC (Framework Convention on Climate Change) 192 Member States (S/N Korea 포함 ) COP-15 held in Copenhagen, Dec New legally binding protocol by 2012 Each MS commits to GHG emission level Major polluters expected to ratify

Global Warming Summary Mechanism : CO2 greenhouse gas from burning fossil fuels Consequence : climate change, ecology disruptions National strategy : low carbon, green growth – Post-Kyoto, Copenhagen Protocol – Carbon tax, credit trading – Develop alternate energy sources Personal strategy – Energy conservation, back to nature

Alternatives to Fossil Fuel Energy Electricity – Present: coal, oil, hydro, nuclear, natural gas – Alternate: wind, solar, tidal, fusion Transportation – Present: oil, coal – Alternate: electric, hybrid, hydrogen Process heat, space heating – Present: coal, oil – Alternate: high efficiency, insulation

CO2 Emissions = Wealth? Per Capita CO2 Emissions for the World

World Energy Production by Source (not including wood or biomass) 86% of World Energy Produced by Fossil Fuels

Renewable Carbon-free Energy Alternatives Hydro power – Potential sites already developed Wind power – Low energy density, site limitations, expansion Solar power – High capital cost, site limitations, expansion Tidal power – Very high capital cost, only special sites

Hydro Supplies 20% of Global Electricity Production

China, Canada and Brazil Lead in Hydroelectric Generation

Photo-Voltaic Panels are too Expensive for the Grid

Toyota Highlander Hybrid Energy-efficient Gas-Electric Hybrid Energy-efficient Gas-Electric Hybrid Transportation is the Greatest Challenge for CO 2 Emissions Reduction

10 Personal Conservation Means (1) Change light bulbs – From regular bulb to fluorescent light – 1 bulb effect : 70 kg CO2 savings/year Drive less – Walk, bicycle, metro subway, public trasport – Every 10 km not driving: 4 kg CO2 savings Recycle more – Home garbage separation for recycle – Half recycle: 1200 kg CO2 savings/year/house

10 Personal Conservation Means (2) Check your tire air pressure – Proper pressure ~3% better gas milage – 1 liter fuel saving: 3 kg CO2 savings Use less hot water – Save hot water while shower, washing Avoid products with a lot of packaging – Resource conservation, reduce wastes Adjust room temperatures – Summer less air-con, winter 1-2 degrees lower 1,000 kg CO2 savings/year/house

10 Personal Conservation Means (3) Plant a tree – 1 tree : 1 ton CO2 absorption/30 year Turn off electric devices – Unused lights, TV, PC, DVD, stereo etc. Be a part of the solution –

Understanding Nuclear Power Double faces of the atom – Military: Hiroshima, Nagasaki – Peaceful: nuclear electricity, nuclear medicine, agriculture, water, etc. Pro/cons on nuclear electricity – Pro: no carbon, no pollution, large scale High-tech infrastructure – Con: nuclear proliferation, waste disposal concerns
