1. Greenhouse Gases Decomposition of Emission Growth Session 5(b) Neil Leary Changing Planet Study Group July 19-22, 2010 Cooling the Liberal Arts Curriculum A NASA-GCCE Funded Project

2. Emissions of CO2 from energy use and industrial sources. Graph generated from CAIT, July 2010: http://cait.wri.org/http://cait.wri.org/ CO 2 emission trends: 5 country comparison

3. Kaya Identity & decomposition C = Pop x GDP/Pop x E/GDP x C/E Emissions = population x per capita income x energy intensity x carbon intensity For small changes: % Δ CO 2 = % Δ population + % Δ per capita income + % Δ energy intensity +% Δ carbon intensity

4. Graph trends in CO 2 drivers with CAIT Login to CAIT: http://cait.wri.org/ Select “CAIT” Select “Graph Trends” Select “Compare Countries”

5. Using pull down menus – Select variable to be graphed – Select time period – Select countries to be displayed – Click “Update”

6. Graphs generated from CAIT, July 2010: http://cait.wri.org/http://cait.wri.org/ Five Country Comparison
