SOH Event Carbon Counter Template - Sydney Opera House

Sydney Opera HouseEvent Carbon Counter TemplatePosters & Brochures Emissions CalculationsOverviewPosters and brochures can be a minor source of emissions for the festivalA comment on recyclingThe main emissions sources are: Where the posters are recycled, the emissions from waste are treated as zero emissionsEmbodied emissions in the manufacturing of the paperWhere recycled paper is used to print posters the emboddied emissions are actually higher than for virgin paper due to the extra processingEmissions from the printing processTransport emissions for the distribution of printing materialEmissions from the waste associated with posters sent to landfillEmbodied emissions in the paper are calculated in the table below based on the volume of paper (by weight)Emissions in the printing process are allowed for by using an emissions factor that captures both paper emissions and printing emissionsTransport and distribution emissions are captured elsewhere in the Logistics worksheet1.

Emissions factor source and descriptionPaper & Poster manufacturing emissions factorsEmissions factors recommended by EPA Victoria are: 100% recycled content 1.907 kg CO2-e per kg of paper consumed, Virgin fibre content 1.867 kg CO2-e per kg of paper consumed (ref http://www.epa.vic.gov.au/climate-change/carbon-management/Worksheet_4-Paper.pdf)Calculation by Energetics for the recent Carbon Expo, modelled in Simapro LCA software by Energetics, produced an emissions factor of 1.39 kgCO2-e/m2Calculations by Energetics for another client recently, based on office paper use, using Simapro’s Ecoinvent 2 database arrived at an emissions factor of 1.83 kg CO2-e/kg paperIn the interest of conservatism and ensuring that emissions are not underestimated we have used the higher emissions factorPrinting emissions factorsEmissions from the printing process have not been included. They are likely to me immaterial in the overall event emissions and the calculations are quite complex.Printing of posters and paper has been included in the calculation via an adjustment to the emissions factor. An average factor from the ecoinvent 2 database has been used. “ printer, laser jet, b/w, per kg printed paper/RER U” 0.24 kg CO2e/kg printed paper. This is for a b/w laser jet office printer, but should be a reasonable proxy. We have increased the emissions factors for posters and papers by this amount.Paper waste emissions factorsThe emissions factor provided for general paper and paperbord waste in the NGA factors is 2.5 t CO2-e / T waste (NGA Factors 2010 , Table 41 )3.
