Our approach to sustainability
Sustainability touches every part of our organisation and operations, from meeting net zero targets, to upholding human rights across our supply chain and maintaining a safe and inclusive workplace for our employees.
Our approach is anchored in three pillars: Planet; People and Partnerships; and Performance and Prosperity.
