Definitions of social innovation abound and a casual observer can quickly become entangled in a debate over meaning and nuance. We’re not too hung up about it so we’ve adopted a simple working definition: Social innovation refers to the creation, development, adoption, and integration of new concepts and practices that put people and the planet first. Social Innovations resolve existing social, cultural, economic, and environmental challenges. Some social innovations are systems-changing – they permanently alter the perceptions, behaviours, and structures that previously gave rise to these challenges.
