Do Developed or Developing Countries Emit More Carbon Dioxide Into the Atmosphere? A Data Management Culminating Project Presentation by Mathew Hall, Dr. G.W. Williams S.S. Aurora, Ontario Thesis Statement As the indicating factors of a country’s development increase, that country will emit more carbon dioxide into the atmosphere because of increased motor vehicle transportation, energy consumption, and urbanization. Background Information Carbon Dioxide Emissions (CO2) Carbon dioxide is an essential gas in the Earth’s Atmosphere It is classified as a “greenhouse gas” Greenhouse gasses trap the suns radiation in the atmosphere, maintaining the temperature of the Earth Carbon dioxide is second to water vapor as the leading greenhouse gas in the atmosphere (Greenhouse Gas 2005) Carbon dioxide levels have risen by 31% since 1895 (The Greenhouse Gasses 2004) One tonne of carbon burned ? 3.7 tonnes of CO2 (The Greenhouse Gasses 2004) 22 billion tonnes of fossil fuels are burned each year (The Greenhouse Gasses 2004) Developed vs. Developing Countries No real scale to judge development World Bank states that a country with GDP per capita of under $6000 US is developing (development- categorizing countries 2005) United Nations uses different indicators such as: life expectancy, literacy rate, enrolment in schools, urban population levels and GDP per capita (development- categorizing countries 2005) In General: Developed Countries ? - higher GDP - more urban population Analysis Causes of CO2 Emissions Fuel combustion accounts for the greatest proportion of CO2 emissions There is an extremely strong linear correlation between total fuel emissions and CO2 emissions Transportation Fairly strong correlation between gasoline consumption and CO2 emissions Inference: Countries that consume more gasoline will emit more CO2 Developed countries consume more gasoline, on average, than developing countries Developed countries consume 2.5 times more gasoline Thesi
