Although market forces driving investors and occupiers are moving faster than regulations right now, new legislation is on the horizon at an international, national and most stringently at a city level. Policies from 16 global cities covering carbon, energy, buildings circularity, biodiversity and resilience show a wide spectrum of commitment and action. For instance, ‘Climate Progressive’ cities such as New York, Paris and Amsterdam are rolling out an array of policy instructions covering new and existing commercial and real estate. New York has introduced several pioneering local laws, while Paris is taking the lead in considering embodied carbon and Singapore has set out a holistic approach to greening its buildings.
