RIFS conducts research with the goal of understanding, advancing, and guiding processes of societal change towards sustainable development.

The issue of justice is increasingly playing a greater role in the transformation towards sustainability. Calls to improve justice outcomes touch on a variety of issues, in particular the distribution of the costs and benefits of transformations as well as the burdens of climate change and environmental degradation. Other claims target procedural aspects: Who should have access to decision-making about transformation towards sustainability? A third set of justice claims focuses on recognition: Which groups are or should be recognized as rights-holders or as affected or especially vulnerable populations?

Air pollution and climate change are closely related. The main sources of CO2 emissions – the extraction and burning of fossil fuels – are not only key drivers of climate change, but also major sources of air pollutants.

While there is still hope that risks from climate change can be limited by cutting greenhouse gas emissions, there is also a perception that ‘time is running out’. This perception of a looming watershed has given rise to calls for research on intentional, large-scale interventions into the climate system, referred to as either ‘climate engineering’ or ‘geoengineering’.

By endorsing the 2030 Agenda for Sustainable Development, the international community signalled its commitment to tackling global challenges through cooperation. The Agenda provides a blueprint for reconciling economic growth with social justice and environmental sustainability.

Economic activities and consumer behaviour in developed countries are currently based mainly on the use of fossil-based raw materials, and their emissions are largely responsible for anthropogenic climate change. In efforts to reduce human effects on the climate, the avoidance of carbon dioxide (CO2) emissions is and remains the most important measure. But high CO2 emissions go hand in hand with a demand for carbon in the form of many of the goods that we need on a daily basis, for example for the production of plastics or fuels. Can it therefore make sense to consider the greenhouse gas carbon dioxide (CO2) as a source of carbon? Since the 1970s, scientists have been researching carbon capture and utilization (CCU) technologies. The aim of these technologies is to re-cycle the CO2 contained in emissions as a feedstock for industrial processes. This captured CO2 could replace fossil-based carbon as a component of materials and energy carriers, thereby creating a carbon cycle.

In the coming decades, the development of renewable energy sources (RES) such as wind and solar will play a major role in reducing our reliance on fossil fuels and making our energy system more sustainable. But the places where RES are available or would be most efficient are often located far away from the densely populated and industrial areas where the energy is needed: on the open sea in the case of offshore wind and in sunnier climes in the case of solar. This means that the construction of new power lines needs to go hand in hand with RES development. In Germany for instance, expanding the electrical grid has become a crucial precondition for the success of the Energiewende.
