The Symposium is aimed at investors, portfolio owners and project developers and provides an invaluable opportunity for open discussion around sustainability in real estate, sharing best practice, debate and forecasting.  The format of the conference provides ample opportunity for informal discussion with speakers and delegates, making it one of the key events to attend for those in the real estate sector.


"To come to a 40 Percent Symposium is to join a committed and thoughtful audience of like-minded property and investment professionals who understand the need to deliver a sustainable future in property."

John Pike, 40 Percent Symposium Founder
