Flexo Sustainable : Fall 2011
Air Travel: CO2 emissions in air travel vary by length of flight, ranging from 0.24 kg CO2 per passenger mile for short flights down to 0.18 kg CO2 per passenger mile for long flights. (Source: U.S. EPA Climate Leaders, http://www.epa. gov/climateleaders/documents/resources/commute_travel_ product.pdf) Rail Travel: The CO2 emissions for rail travel vary by distance of the trip. On average, commuter rail and subway trains (< 20 miles) emit 0.35 lbs CO2 per passenger mile (or 0.16 kg per mile), and long distance trains (>20 miles) emit 0.42 lbs CO2 per passenger mile (0.19 kg per mile). Transportation conditions vary in real life beyond what can be estimated. To ensure that rail calculations fully cover a trip, add 10 percent to the total mileage of the trip to account for potential detours, stops, and other issues.

Inner city commuting buses (< 20 miles) emit 0.66 lbs CO2 per passenger mile (0.30 kg per mile), and long distance bus trips (>20 miles) emit 0.18 lbs CO2 per passenger mile (0.08 kg per mile). Road and transportation conditions vary in real life beyond what can be estimated. To ensure that calculation fully covers a trip, add 10 percent to the total mileage of the trip to account for potential traffic jams, detours, and pit-stops that may arise.

For upscale hotels, emissions are calculated at 33.38 kg CO2 per room day (Source: U.S. Environmental Protection Agency, http://www.epa.gov/chp/ documents/hotel_casino_analysis.pdf) Meals: The average person's diet contributes 2,920 kilograms CO2e to the atmosphere each year. By dividing by 365, it is deduced that a person emits, on average, 8 kg CO2e a day from their meals. This calculation is based on an average US, non-vegetarian diet. The emissions for food preparation are not included in this calculation.

With nearly 60 percent stating that the trend to become more sustainable was increasing, flexo printers need to take action. And, there is a real possibility that carbon footprinting and reduction of carbon emissions may become regulatory requirements for printers someday. Be proactive and prepared. This article has provided the most current technical infor- mation to calculate the carbon footprint a flexo facility. As this information will most likely expand and change, it is impor- tant to research the most current conversions. For example, eGrid conversions to determine the carbon emissions from purchased electricity change annually, but updates will be available online. There are quite a few online calculators that can be used to at least calculate portions of a facility 's carbon footprint. For other calculations, spreadsheets can be created. Docu- ment the sources of the conversions and each element of the inventory. If you're using online calculators document that as well. 1Editor's Note: This article was developed as a joint effort of the FTA Sustainability Committee. For additional information, contact Doreen Monteleone, FTA director of EHS, member- ship & special projects at email@example.com. For examples of calculations, based on information contained in the charts presented here, see FLEXO's August, September, October and November editions.
