This report considers potential policy options to promote ‘systemic innovation’ that foster decarbonisation, with a specific focus on the EU. By using the term ‘systemic’, we point to a variety of domains in which innovation can occur – not only technological, but also organisational innovation, (brought about by disruptive new business models); institutional (by revising both legal and economic incentives); and societal (requiring a change in consumption and behaviour), and emphasise how entire systems (e.g., energy, mobility, shelter) can be transformed through socio-economic change.
