For eight years, the Planet Mark Awards celebrated our community and those driving continuous positive change. Now, we’re building on that legacy with the Sustainability Summit, a daytime event incorporating interactive sessions, engaging learning experiences, and meaningful networking.
Taking place on November 3rd, the Summit brings together expert-led discussions and powerful stories from our Award winners and the impactful work of our Planet Mark Members. Attendees will exchange ideas and learn from shared challenges, ensuring valuable takeaways for all.
We’re delighted that the Summit is taking place at the Barbican Centre, one of the UK’s architectural treasures and one of the world’s leading arts centres. The majestic Barbican Conservatory will be open to attendees to explore its vibrant collection of 1,500 species of plants and trees.
