During the past year, we have made significant progress in identifying and prioritising those aspects of our business which have the greatest stakeholder impact. We spent nine months working alongside sustainability experts on a rigorous materiality assessment, applying the Global Reporting Initiative principle of materiality, as well as reflecting our wider contribution to the 17 UN Sustainable Development Goals (SDGs). This work builds on our ongoing commitment to the UN Global Compact and its ten principles, to which we have been a signatory since 2004.
Together with partners and customers around the globe, we work towards our vision of making food safe and available everywhere, which is widely recognised as one of the most pressing issues of our time.
We expanded our involvement in school feeding programmes, working with governments and other partners to bring nutritious beverages in Tetra Pak packages to more than 72 million school children in 58 countries. We have been engaged in these programmes for more than half a century.
And we broadened our “deeper in the pyramid” activities, working with customers in various parts of the world to help bring a wide variety of affordable, safe, nutrient-rich products to the market. In doing so, we offered a broad range of services, based on our long experience in this area. From helping customers to identify nutritional gaps, develop product concepts and define regionally-appropriate recipes, to working with them to negotiate funding alliances, develop distribution solutions and secure local suppliers.
When it comes to protecting people, one of our principal areas of focus is our Occupational Health and Safety (OHS) agenda, designed to help ensure the wellbeing of all who work for, or with, our company. In 2017, we completed the certification of all our manufacturing sites in accordance with OHSAS 18001. About 110 OHS officers received training and each factory now has a three-year plan for OHS.
On another level, our commitment to protecting people is about supporting the development of our employees, offering rewarding careers with opportunities for progression and continuous learning. Last year we launched our Future Talent programme, which reflects our long-term commitment to hiring a steady stream of graduates from around the world, offering them a structured agenda of on-the-job training and development, as part of their career with Tetra Pak.
Following the commitment, we made in 2016 to be using only renewable electricity by 2030, last year we made further progress towards that goal, with five of our factories now purchasing 100 per cent green electricity. By the end of the year our proportion of renewable electricity passed 40 per cent of our total consumption.
The year also marked the tenth anniversary of the decision to use paperboard sourced from forests that are certified by the Forest Stewardship Council™ (FSC™). In the decade since, we have delivered more than 300 billion FSC-labelled packages to customers across the globe and we have achieved full FSC Chain of Custody certification of our converting plants and market companies. It means we can now supply FSC-labelled packages from anywhere in the world.
Also in 2017, we became the first company in the food packaging industry to have our climate reduction targets approved by the Science Based Targets (SBT) initiative. We are committed to reducing our operational greenhouse gas emissions by 42 per cent by 2030 and by 58 per cent by 2040, from a 2015 baseline.
SBT is a global partnership between CDP, the World Resources Institute, World Wide Fund for Nature and the United Nations Global Compact, to which over 210 companies have committed.
Post-consumer recycling remains a top priority for Tetra Pak and we continue to make good headway in many geographies. For example, in 2017 we passed a key milestone in the US when it was confirmed that more than 60 per cent of households now have access to carton recycling. It means cartons can now carry a “Please Recycle” logo, without the additional caveat “where facilities exist”.
