Hammerson was one of the first major property developers to address sustainability considerations seriously and systematically. Our developments from 2003 onwards saw a series of innovations, ranging from local employment programmes to natural ventilation. With our development activity again increasing, we are focusing on designing and delivering buildings that will operate efficiently over the next 50 years or more. This means ensuring that environmental and social sustainability are designed into a scheme alongside economic sustainability, from the outset. It also means reflecting on the many social, environmental and technological changes that will take place over that period.
