Since net zero targets have become a keystone of climate policy, more thought is being given to actively removing carbon dioxide from the atmosphere while continuing to drastically reduce emissions. The ocean plays a major role in regulating the global climate by absorbing a large proportion of...

If the EU wants to achieve net zero emissions by 2050, enacting conventional climate change mitigation measures to avoid emissions of greenhouse gases will not be enough. To compensate for unavoidable residual emissions, unconventional measures to remove CO2 from the atmosphere will also be...

Climate policy in the European Union (EU) and Germany changed significantly with the adoption of net-zero emissions targets. A key new development is the growing importance of carbon management. The umbrella term includes not only the capture and storage of CO2 (carbon capture and storage, CCS),...

Following the conclusion of the 'Fit for 55' package, European Union (EU) climate policy will enter its next phase. One of the most important decisions will be how to set the economy-wide emissions reduction target for 2040, which will form the starting point for the next round of revisions of...

The ongoing global financial crisis has been preceded by a steady rise in global current account imbalances. Recently, in the course of the global recession, global imbalances have declined, albeit without having disappeared completely. As the outlook for global growth gets brighter, it is...

Diminishing emission budgets and increasing risks of catastrophic damages from climate change require analyses of rapid response options including geoengineering options such as ocean iron fertilization (OIF). To decide whether or not OIF might be such an option an assessment of its potential as...

Despite large uncertainties in the fertilization efficiency, natural iron fertilization studies and some of the purposeful iron enrichment studies have demonstrated that Southern Ocean iron fertilization can lead to a significant export of carbon from the sea surface to the ocean interior. From...
