Transitioning to a net-zero world is one of the greatest challenges humanity has faced. It calls for nothing less than a complete transformation of how we produce, consume, and move about. Within organisations this transformation is driven by the chief sustainability officer (CSO). The CSO is emerging as the guiding light in the organization and is being asked to interpret changes in the external sustainability environment and work out the strategic consequences for their organisations. The CSO is also charged with influencing, communicating, and cutting through the organisational complexity to allow their firm to deliver on ESG commitments. The role of the CSO is evolving as organizations have a long way to go before sustainability is fully embedded into every function, process, and person. Net Zero Professional will deliver the latest technology, processes and thought leadership to guide CSOs and other executives and managers charged with delivering the net-zero promise.
