Our 2020 climate goal is to cap greenhouse gas (GHG) emissions across the value chain at 2010 levels while continuing to grow our business. In 2016 we made significant progress against this target, achieving a 16 per cent reduction against the 2010 baseline, at the same time as achieving a 19 per cent increase in the number of packages sold.
The breakdown of the total value chain emission according to the GHG Protocol’s scopes is presented in the table below. Emission reduction is calculated by comparing the absolute value chain emissions to previous year and to 2010 (which is the baseline year for our 2020 climate goal). Scope 3 results per category can be viewed on Tetra Pak’s CDP Climate disclosure.
Over 90 per cent of the GHG emissions in our value chain come from our suppliers in the production of raw materials and from our customers’ sites when they use our processing and packaging equipment.
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 total for 2016 was calculated using the “market based” methodology. This means that we have used supplier-specific emission rates where available, in line the GHG Protocol Scope 2 Quality Criteria, and that our results reflect the use of renewable electricity at our sites. Along with achieving a reduction in our value chain emissions, we have also reduced our Scope 1 and 2 emissions.
The main contributor to our scope 1 and 2 emissions is purchased electricity across our sites accounting for approximately 75%. The main driver for the reduction of our scope 1 and 2 emissions has been the increased use of renewable electricity as well as initiatives to improve energy efficiency in our sites.
We monitor the emissions of our packaging material operations per million standard packages produced.
The energy use reported includes purchased 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 below depict total energy consumption across our operations around the world. Energy use has remained relatively stable, despite increases in production. Our converting factories consume 81 per cent of the total energy used across our operations.
We monitor the energy efficiency of our packaging material operations by measuring the energy used to produce a million standard packages. As shown in this chart, this indicator has remained stable in recent years with no major fluctuations.
Purchased electricity is the main energy source used in our operations. Of the electricity that we consume 35% came from renewable sources in 2016.
In 2016, our renewable mix stood at 35 per cent, up from 22 per cent in 2015.
The data in this section covers the raw materials used to produce our carton packages, including laminates, closures, straws, strips and film.
The chart below shows the relative proportions of each type of raw material that go into our packages.
Material waste is measured as the difference between raw material consumed and packaging´material produced. The material waste rate is the factory weighted average waste percentage. The figure below shows the steady reduction of packaging material waste over the years.
Waste handling covers all solid waste produced in our packaging and additional material
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 table depicts total water consumption across the Tetra Pak sites. The amount of water we use is modest; nevertheless, we seek to minimize usage as much as possible.
The main water source for Tetra Pak is municipal water supplies (63 per cent) followed by groundwater (30 per cent). In 2016, office locations were not asked to report their water withdrawal sources in annual environmental data collection from sites and thus their water use is reported as other/unspecified.
Our converting factories account for the largest percentage of water use, followed by those operations that assemble machines and equipment.
In much the same way as we measure energy intensity, we monitor the water used in our operations per million standard packages.
Emissions from ozone-depleting substances result from CFC/HCFC leakages. Tetra Pak policy is to replace CFC, 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.
VOC emissions arise mainly from solvents used in printing inks and, to some extent, from printing plate production. The data below represents total VOC emissions to air, after abatement equipment.
We also measure VOC emissions per million standard packages.
The number of FSC-labelled packages we deliver to our customers has been steadily growing since 2007, when we launched the first FSC-labelled beverage carton.
Post-consumer recycling is an essential part of our environmental agenda. In 2010, we set ourselves a goal of doubling our recycling rate to 40 percent by 2020 and since then we have succeeded in increasing the numbers of packages recycled annually.
