Based upon 15 years of international experience in sustainability strategy and implementation, we have developed a process tool to assist companies with the conception of sustainability as a key element of business strategy. The tool, called GLOBE-US, finds its basis in the Business Model Generation-approach of Osterwalder and Pigneur. GLOBE-US is comprised of 7 steps, starting with the original business model. Through the relevant material issues, the tool focuses on value creation and ultimately redesigning business models.
