× N2O emission factor (lbs CH4/kWh) / 2204.62 lbs/metric ton) × 310 GWP = CO2e Emissions (metric tons) GWP is based on CO2 to calculate the CO2e for CH4 and N2O. FORMULA APPLIED As an example, a fictitious flexo plant in Bohemia, NY wants to calculate Scope 2 of its carbon footprint for 2010. During that year the plant used 5,359,000 kWh of electricity. Ac- cording to U.S. EPA’s eGrid, NPC Long Island’s Annual Total Output Emissions rates for 2007 (most recent year available) were reported as: CO2 = 1,418.74 lb/MWh CH4 = 90.50 lb/GWh N2O = 13.10 lb/GWh CO2 Calculation: 1,418.74 lb/MWh = 1.41874 lb/kWh (5,359,000 kWh x 1.41874 lb/kWh) / (2,204.62 lbs/metric ton) = 3,448.68 metric tons CO2 CO2e from CH4 Calculation: 90.50 lb/GWh = 0.00009050 lb/kWh (5,359,000 kWh x 0.00009050 lb/kWh) / (2,204.62 lbs/metric ton) x 21 GWP = 4.62 metric tons CO2e CO2e from N2O Calculation: 13.10 lb/GWh = 0.00001310 lb/kWh (5,359,000 kWh x 0.00001310 lb/kWh) / (2,204.62 lbs/metric ton) x 310 GWP = 9.87 metric tons CO2e Total Scope 2 Emissions 3,448.68 + 4.62 + 9.87 = 3,463.17 metric tons of CO2 and CO2e These equations can be used whether a facility is reporting Scope 2 emissions for a year or breaking it down monthly. It cannot be overstated that when doing any of these calcu- lations, the sources of the emission factors must be docu- mented. Otherwise, it will be impossible to make comparisons from year-to-year or between facilities with any confidence. The fuel sources of your local utility will have a significant impact on the conversion factors and resultant total emissions for any particular location. n Editor’s Note: This multi-part series of articles, which first began appearing in August 2011, is being developed as a joint effort of the FTA Sustainability Committee.

GREEn PAckAGInG tO REAch $212 BILLIOn In 2015 World demand for green packaging is projected to rise 5.7 percent per year to $212 billion in 2015, according to World Green Packaging, a new study from The Freedonia Group, Inc. The Asia/Pacific region will see above-average gains and remain the largest regional market in the world, due to its large food and beverage industries. Central and South America, Eastern Europe, and the Africa/Mideast region will also experience above-average growth The United States, which accounted for 23 percent of global sales in 2010, is the largest national green packaging mar- ket in the world by a wide margin. Other large, generally mature markets include Japan and Germany.
