Our ambitious climate impact target covers every aspect of the value chain, from the raw materials we source all the way through to how our products are handled after use. Our biggest single climate impact results from energy consumption in our own operations and elsewhere in the value chain: more than 80% of the carbon emissions related to our products actually come from our suppliers in the production of raw materials and from our customers’ sites when they use our processing and packaging equipment.
Data validated for 2015 showed CO2e emissions across all parts of the Tetra Pak value chain down 15% from a 2010 baseline, despite a 16% increase in production over the same time period.
Since 2010 and compared with the baseline set at the time, we have avoided 6.7m tonnes of CO2e across our value chain. This is equivalent to the annual emissions of 1.4 million passenger vehicles.* Just half of this CO2e saving would be equivalent to reducing emissions from our own production sites to zero for each year since 2010.
We set clear criteria to ensure that all the raw materials we use come from sustainable sources wherever possible, and have minimal impact on the environment. We will only work with suppliers that share those values, and we encourage them in identifying opportunities to cut energy losses and make the supply chain more efficient.
Every year, we evaluate the operations and environmental performance of our suppliers, including of paperboard, polymers, aluminium and ink. Greenhouse gas emissions are a key parameter in the evaluation process.
Electricity consumption in our factories has remained almost flat since 2005, while our business has grown more than 30% during the same period. Audits of our own factories carried out by external energy experts have identified additional opportunities to reduce energy use by 10-12%. We are currently implementing these recommendations and sharing best practice across all our sites. By the end of 2015, we had implemented around 63% of identified savings and were on track to reach 91% by the end of 2017.
The 2015 climate efficiency result for Supply Chain Operations Packaging Material showed an improvement of 21% compared with the 2010 baseline. Our work to increase efficiency covers use of all resources, as well as energy, and includes our customers’ operations.
At the same time, we are looking to the future and exploring ways of continuing to manage our impact even after we have maximized our efforts to reduce consumption. One way is by increasing our use of renewable energy.
We are already using energy from renewable sources at selected sites. We currently have solar panel installations in seven factories, while four are purchasing 100% green electricity. A programme to generate renewable electricity onsite has already reached a capacity of 1MW and we are working to expand the programme. Through these efforts, we are achieving annual carbon savings equivalent to 29,059 tonnes of CO2. We are also investing in renewable energy projects in developing countries – including Turkey, China and Taiwan – via the GoldPower renewable energy certificate scheme. Since 2005, our renewable energy purchases have resulted in avoided emissions equal to 400,000 tonnes of CO2e – equivalent to the total emissions of our own global operations for a whole year. Avoided emissions are always reported separately and not deducted from our total greenhouse gas results.
In addition, we have strengthened our commitment by signing up to RE100 – a global network of businesses that have made a public pledge to procure 100% of their electricity from renewable sources within a specified timeframe.
We look for ways to reduce the impact of transportation and travel, both of products and of people:
We support our customers to reduce their carbon footprint and costs in many different ways, including by creating and delivering more efficient processing and filling solutions and developing services to reduce energy use, water consumption, waste and food loss at their sites. These recent initiatives are helping customers reduce their environmental impact at the same time as improving operational efficiency:
Ultrajaya is Indonesia's leading producer of aseptically packaged dairy products and one of our key customers. Ultrajaya’s commitment to protecting the environment and supporting the local community includes supporting projects to plant trees, provide materials for local schools and improve infrastructure – and working to make its own operations more efficient. When Tetra Pak learned that the Ultrajaya factory was facing stoppages due to low water supply, we started to look at ways to reduce the amount of water consumed by their filling machines. Analysis showed that reusing 50% of the water from the machines’ compressors would solve the problem. Not only did this solution reduce time lost through stoppages and therefore increase production, it helped to conserve water – daily consumption has been cut by 32.4m3.
A new version of our Carton CO2 calculator is giving our customers an even clearer view of the carbon footprint of the packages they use, across a wider section of our portfolio. The calculator shows the CO2e footprint of our cartons under European conditions up to moment when the packaging material leaves our factories, enabling our customers to make a better-informed choice of packaging. The new version, launched in March 2016, now includes more cartons and caps, including those made from bio-based materials, and moves us closer to our ambition of having a calculator that covers our entire portfolio. It also reflects our latest data on performance and emissions, giving a more accurate picture of overall climate impact.
When used carton packages go to landfill, they can decompose and contribute to climate change. We’re working to reduce this by increasing recycling of used Tetra Pak beverage cartons; we are also working to increase the recycling of the materials used in our own operations.
