A business model canvas is a methodology that a strategy designer should use to help stakeholders understand the impact of making sustainability a new core value on current products and services. A business model canvas is a tool that helps describe, design, and evaluate the key elements of a business model, such as value proposition, customer segments, revenue streams, cost structure, and key resources. It helps assess the desirability, viability, and feasibility of a product or service, and identify opportunities and risks for improvement or innovation.
