The data presented in this section covers Tetra Pak's scope 1, 2 and 3 greenhouse gas (GHG) emissions. The GHG emissions are accounted according to the GHG Protocol principles developed by the World Resource Institute and the World Business Council on Sustainable Development. Our scope 1 and 2 GHG accounts have been audited by an independent third party since 2006 and our scope 3 accounts since 2013.
Our GHG accounting methodology was revised and updated in 2021. The figures for 2019 and 2020 have been restated in line with this new methodology.
Our operations climate impact comprises of both scope 1 & 2 emissions and category 6. Scope 1 includes direct emissions from our own operations, including fuel consumption, the use of refrigerants and solvents. Scope 2 includes indirect emissions related to purchased electricity, heat, steam or cooling. Our scope 2 was calculated using the “market-based” methodology. This means that we have used supplier-specific emission rates where available, in line with the GHG Protocol Scope 2 Quality Criteria. The main drivers to reduce emissions have been actions to further improve energy efficiency at our sites as well as increased use of renewable electricity. The main contributor to our scope 1 & 2 emissions is purchased electricity to our sites.
The energy use reported includes purchased and on-site generated electricity, the use of fossil fuels such as natural gas and district heating (hot water/steam). Electricity is the main source of power for our operations. Fuels are used both for heating and for process-specific purposes such as drying printing inks. The charts depict the total energy consumption across our operations around the world. Energy use has remained relatively stable, despite increases in production. Our packaging material converting factories are the most energy intensive operations and they consumed 75% of the total energy used across our operations in 2021.
Purchased electricity is the main energy source used in our operations. Of the electricity that we consume, 80% came from renewable sources in 2021.
We monitor the energy intensity of our packaging material operations by measuring the energy used to produce a million standard packages. As shown in the chart, this indicator has improved steadily over the years as a result of dedicated energy audits and energy efficiency projects at our facilities. In the recent years we see this improvement gradually decreasing as most of the main energy saving opportunities have been realized.
Emissions of ozone depleting substances result from CFCs/HCFCs* leakages. Tetra Pak policy is to replace CFCs, halon and all other substances with high ozone depleting potential with alternative substances that have a lower environmental impact. Since implementing this policy our emissions from ozone depleting substances have dropped to marginal levels.
*CFCs: ChloroFluoroCarbons, HCFC: HydroChloroFluoroCarbons
VOC emissions arise mainly from solvents used in printing inks and, to some extent, from printing plate production at our packaging material converting factories. The data represents total VOC emissions to air, after abatement equipment. It includes both process emissions, stack emissions, as well as fugitive emissions. In order to reduce these emissions, we have been installing Regenerative Thermal Oxidizers (RTOs) at many of our sites. Furthermore, we are continuously innovating our processes to reduce the use of organic solvents in our production.
The graph shows our VOC emissions per million standard packages produced.
Material waste is measured as the difference between raw material consumed and the packaging material produced. The material waste rate shown here is the factory weighted average waste percentage. The figure shows the steady reduction of packaging material waste over the years. This improvement is driven through our World Class Manufacturing approach.
Reported waste covers the handling of all solid waste produced in our production and equipment assembly sites, including production waste and any other types of waste from sites. The chart shows the proportions of waste that is recycled, incinerated either with or without energy recovery, and sent to landfill.
The data in this section depicts total water withdrawal across the Tetra Pak sites. The amount of water we withdraw is modest; nevertheless, we seek to minimize usage withdrawal as far as possible. Our converting factories account for the largest percentage of water use, followed by those operations that assemble machines and equipment. In order to understand which of our sites are located in water stress areas we have used the WRI Aqueduct Water Risk Atlas tool do the assessment. It is assumed that all water withdrawn for our sites is fresh water.
Tetra Pak goes well beyond legal requirements and applies international environmental standards to ensure that environmental issues and impacts are managed in a systematic way. Certification status at the end of 2021 at our manufacturing sites:
We collect recycling data from all markets we operate worldwide. Reported used carton package recycling rate is based on the share of cartons collected and sent for recycling versus cartons deployed. We use recycling information from public sources when available, e.g., The Alliance for Beverage Cartons and the Environment, Packaging Recovery Organizations, etc. and also consolidate an internal reporting with inputs from our local recycling teams to make sure to have the broadest possible set of data.
