Calculating CO2 for a Tetra Pak Carton

MoreInfo

Scope of the CO2 calculator

The results from our carton CO2 calculator show the CO2 footprint of the carton under European conditions up to the moment when the packaging material leaves our factories. An assessment across the full life cycle requires additional data that varies locally, and with each specific product. For example distribution distances vary depending on where each package is filled and sold; some filled packages are stored chilled while others not; some packages will be recycled, others not.

Moulding of caps and tops in the filling machine is not included in the results. This is relevant for the Tetra Top and Tetra Evero Aseptic packages, and any direct injection moulding concept (DIMC) caps.

Indicative results

The calculated results are not exact; they are indicative and based on a number of simplifications. To get the exact CO2 footprint of a package you need to know its specific material composition, in which converting factory it was produced and whether raw materials were brought to Tetra Pak by train or truck. We have used the most common material specification for each package as the basis for the calculation of the results.

Package specifications and weights vary locally and with product protection requirements. CO2 footprint data will necessarily change over time as methodologies and data are refined.

Use of the results

The results should not be used to support comparative assertions made to the public nor directly for labelling. Any such use would fall outside of the requirements of the relevant ISO standards.

Comments on this version

The results should not be compared with those generated in earlier versions of the CO2 calculator. In this updated version, made available June 2017, changes were made to the package portfolio. Emission factors and material specifications were last updated October 2016.

Bio-based caps and packages are now included in the CO2 calculator. For the bio-based caps, it is the HDPE (high density polyethylene) part that is bio-based, made from renewable HDPE derived from Brazilian sugar cane.

Calculations

The calculations were made with latest (as available January 2016) available industry average data and for European conditions. For production of liquid packaging board average data as presented by The Alliance for Beverage Cartons and the Environment (www.ace.be) was used, for plastics data as presented by Plastics Europe was used (www.plasticseurope.org), and for aluminium foil data as presented by European Aluminium Association was used (www.eaa.net). Data for production of bio-based PE was sourced from the LCA made available by Braskem in 2013 (www.braskem.com.br).

For the converting operations global average data from Tetra Pak's sites have been used, representing the performance in 2015. The impact of the transport of raw materials to the converting factory is included in the converting result. Transport modes and distances are averages as presented by The Alliance for Beverage Cartons and the Environment (www.ace.be).

Uptake or release of biogenic carbon to and from the material is not included in the results. Biogenic carbon embedded in the material is reported separately.

The methodology employed is in line with the ISO standard on LCA (ISO 14040 and 14044).
