Evaluation of the KlimAdapt project

With a focus on the German Climate Preparedness Portal

After five years of operation, a comprehensive evaluation of the KlimAdapt project, consisting of the German Climate Preparedness Portal (KLiVO-Portal) and its accompanying network, was carried out in 2024. The aim was to examine the impact and use of the portal, particularly from a user perspective. The evaluation is divided into five main questions, which were answered through a secondary analys...read more

Towards a standardised approach to Regional Enviromental Management Plans in the Area

The International Seabed Authority (ISA) aims to develop Regional Environmental Management Plans (REMPs) in marine regions where there is an interest in deep-sea mining. The REMPs will be a sectoral management tool and offer the opportunity to implement an ecosystem-based management approach. The presented study aims to contribute to this discussion by recommending a standardised approach for the...read more

The benefit sharing regime of the International Seabed Authority

The member states of the International Seabed Authority are currently negotiating a comprehensive code for deep seabed mining in areas beyond the limits of national jurisdiction. This study aims to take a holistic approach to the problems of equitably balancing the economic and financial benefits that may arise under the law of the sea. We present the legal requirements, analyse the issue of benef...read more

Test mining in the Area: Legal, regulatory, environmental governance and scientific perspectives

The International Seabed Authority, ISA, controls the areas beyond national jurisdiction and its mineral deposits and has the obligation to effectively protect the marine environment from the potentially harmful effects of exploration and extraction activities. What is required is appropriate mining techniques and that tests are carried out to ensure that there will be no adverse effects. In the c...read more

Report on typical GHG emission values for the cultivation of agricultural raw materials for NUTS 2 regions or a more disaggregated level in Germany according to RED II

This report explains the calculation of the updated typical greenhouse gas emission values for the cultivation of agricultural raw materials for NUTS 2 regions in Germany and presents the results. The calculations for eleven energy crops are based on updated input variables consisting of standardized factors and comprehensive data sources such as yields, fertilizer consumption and diesel consumpti...read more

Solar Radiation Modification (SRM)

Concepts, Risks and Governance of intervention in the global climate system through solar geoengineering

Solar Radiation Modification (SRM) can neither conserve the current nor restore the pre-industrial climate. It would create an unpredictable new global climate with significant regional impacts. This brochure explains the risks of SRM for food security, justice and actual climate action. It explains the various SRM approaches and how they are supposed to work. It also describes the state of regula...read more

Optimisation potential with regard to the processing and recycling of waste oil

Evaluation of the collection categories with regard to their suitability for regeneration and the effects of changes in mobility and technology on the distribution and composition of the collection categories

On the one hand, the research project updated the calculation basis of the model used by the Federal Environment Agency to calculate waste oil flows, and on the other hand, analyses of waste oils were carried out to examine their reprocessability. Here, suitable waste oils from certain areas of application were identified only in individual cases for waste oils assigned to collection category 2 of...read more
