Celebrating a year of outstanding achievement at the iiE Awards 2025
This year’s event featured an inspiring talk from a leader in nature restoration, unmissable networking opportunities, and expert-led workshops.
Held at KingsGate Peterborough on Thursday 20 November, the iiE Awards 2025 saw members come together to recognise the green achievements of businesses and organisations across the membership and beyond.
Attendees had the opportunity to exchange ideas and quiz environmental specialists during morning of sustainability-themed workshops on carbon footprinting, transport, nature, social impact, and more.
Introduced by event compère Sarah Mukherjee MBE (CEO of ISEP and a former BBC environment correspondent), this year’s keynote speaker was Archie Struthers, CEO of world-leading nature restoration company Nattergal.
