Phil Williams / Plan-it Eco (Sustainability Champion)

Sustainability and global citizenship is our collective future. There is no getting away from it. As consumers, each and every one of us has the ability to make informed and positive choices about how we choose live and work, and so through the aggregation of sometimes marginal gains, we can affect change. We all know this to a greater or lesser degree, and some of us even act upon it. There are few however amongst us, brave enough to set aside an otherwise successful career, in dogmatic pursuit of really making a difference and changing the world.


Phil Williams is a truly inspirational character and just such a man. Through imagination, personality and sheer force of will, he has captured the hearts and minds of people and businesses across the globe with his practical and pragmatic messages. Critically, he has also saved businesses a great deal of cold hard cash in the process.

If your business isn’t quite as sustainable as it could be; Phil is your guy
