The IIIEE conducts research to advance strategies for sustainable solutions pursued by public authorities, businesses and communities – internationally, nationally and locally. The IIIEE's research synthesises insights from natural sciences and engineering on sustainability challenges, targets and scenarios with ideas from social sciences --- including economics, political science, organisational, legal and behavioural studies, --- which explain how societies, communities and organisations react to these challenges, develop and transform.

The IIIEE advances strategies for sustainable solutions through identification, evaluation and development of visions, pathways, and scenarios for sustainability; policy, economic and business tools and models for supporting transitions to sustainability as well as processes of strategic change towards sustainability. The research at the IIIEE is structured around the following themes:
