In the words of the UN Environment Programme: “The state of the planet affects us all – both now and in the future. No matter who and where you are, everyone alive right now has a critical role to play for the future of land.” Every year, World Environment Day reminds us of our collective responsibility to protect the planet. In the UK, local authorities are at the forefront of this mission, striving to meet ambitious sustainability targets that are driven by national legislation, regional initiatives, and international commitments.
