#OnlyOneEarth: World Environment Day 2022

Join with us as we highlight the urgent need for environmental action this World Environment Day (5 June) alongside the UN Environment Programme (UNEP).

World Environment Day is a United Nations (UN) Environment initiative held annually on the 5th June. It has highlighted important global issues since its origins in 1974 – including climate change, marine pollution and wildlife crime. Each year we work to champion the initiative in the UK and beyond – and 2022 is no different!

As noted by the UN, the 2022 World Environment Day global campaign #OnlyOneEarth calls for transformative changes to policies and choices to enable cleaner, greener, and sustainable living in harmony with nature.
