- 2. WHAT WE KNOW The level of greenhouse gases in the atmosphere have increased, causing the Earth’s temperature to rise. One greenhouse gas in particular, carbon dioxide (CO2) has steadily increased over the past century largely due to human activity (anthropogenic). We know that emissions have a significant impact on the world around us. How can we reduce the amount of carbon that is emitted?
- 3. What is mitigation? • To decrease force or intensity. To lower risk. • Earthquake mitigation • Flood mitigation • Climate change mitigation
- 4. How can we reduce carbon emissions? • Work in pairs to talk about ways in which we could reduce (mitigate) carbon emissions in the following areas. Feel free to write your answers in the appropriate column on the board: – Transportation – Heating and Cooling Buildings – Industry Carbon Output – Electricity Use
- 5. Mitigation Strategy #1: Transportation Efficiency A car that gets 30 mpg releases 1 ton of carbon into the air for every 10,000 miles of driving Fuel efficient cars get more miles per gallon (mpg) Increasing the fuel efficiency of cars will reduce the amount of CO2 emitted into the atmosphere
- 6. Mitigation Strategy #2: Transport Conservation With more cars on the road, the amount of CO2 emitted steadily increases. Reducing the time and number of cars on the road will reduce emissions. Increasing the use of public transportation would reduce the amount of individual driving time.
- 7. Mitigation Strategy #3: Building Efficiency Providing electricity, transportation, and heat for buildings produces high levels of CO2 emission. Reducing heating and energy use would reduce the amount of carbon released into the atmosphere. Insulating buildings, using alternative energy sources, and solar water heating are ways to reduce emissions.
- 8. Mitigation Strategy #4: Efficient Electricity Production 25% of the world’s carbon emissions come from the production of electricity at coal plants. Since nearly 50% of electricity comes from coal combustion, improving coal plant efficiency will significantly reduce carbon emission. To do this requires alternative ways of using coal to produce electricity.
