The UK government’s new Sustainable Development Strategy, Securing the Future, places greener innovation and local action at its foundation. Yet these two themes are considered apart: greener innovation is presumed to be an industrial concern, whilst local action is identified with the community dimension of sustainable development. In practice, the grassroots has often pioneered highly innovative approaches to sustainable development, and it continues to experiment with social and technical innovations today. Participants in this one-day conference will learn more about the innovative potential of grassroots activities.
