Reverse emissions or influence solar radiation: Is “geoengineering” worthwhile, feasible and if so, at what price?
SWISS ACADEMIES FACTSHEETS, VOL. 13. NO. 4, 2018
The aim of the Paris Agreement is to limit global warming to well below 2 degrees Celsius, if possible even 1.5 degrees Celsius. Various scenarios show that very great efforts are necessary to achieve these goals through emission reduction measures alone. This motivates the search for additional solutions. Technical interventions in the climate system, often referred to by collective terms such as “geoengineering” or “climate intervention”, are therefore discussed. However, most of these measures are associated with costs, risks and undesirable side effects that have so far been very difficult to assess. While some measures only exist in theory, others have been tested in small format, but nevertheless there is a lack of knowledge about the effects of an application on the required large scale. Since the measures would not have the same effects in different parts of the world, ethical questions of global and regional justice are also particularly important and should be covered by international regulations.

Ethical guidelines for animal experiments
The Swiss Animal Welfare Act permits the use of animals for certain scientific purposes; at the same time, however, it requires that the dignity of animals be respected and their welfare protected. For researchers, reconciling these various societal interests can be challenging. The ethical guidelines for animal experiments (2025) are designed to clarify the margin of discretion left by the legislation and to encourage researchers to reflect on the handling of animals in their experiments. The decisive factors for updating the previous version from 2005 were new scientific knowledge and research methods on the one hand, as well as changes in the legal framework on the other.
