    Description: Net-zero climate policies foresee deployment of atmospheric carbon dioxide removal wit geological, terrestrial, or marine carbon storage. While terrestrial and geological storage would be governed under the framework of national property rights, marine storage implies that carbon is transferred from one global common, the atmosphere, to another global common, the ocean, in particular if storage exceeds beyond coastal applications. This paper investigates the option of carbon dioxide removal (CDR) and storage in different (marine) reservoir types in an analytic climate-economy model, and derives implications for optimal mitigation efforts and CDR deployment. We show that the introduction of CDR lowers net energy input and net emissions over the entire time path. Furthermore, CDR affects the Social Cost of Carbon (SCC) via changes in total economic output but leaves the analytic structure of the SCC unchanged. In the first years after CDR becomes available the SCC is lower and in later years it is higher compared to a standard climate-economy model. Carbon dioxide emissions are first higher and then lower relative to a world without CDR. The paper provides the basis for the analysis of decentralized and potentially non-cooperative CDR policies.

    Description: Limiting global warming to 1.5°C requires a large-scale removal of carbon dioxide from the atmosphere. The oceans have been proposed as one possible storage option, however, not without environmental consequences. Adverse impacts on ecosystems are expected to increase in the amount of carbon stored. The question arises whether the removed carbon should be stored in a small area, e.g. a bay, or spread out across the oceans. We study this question in an analytic model with two types of ocean boxes, characterised by their carbon content. Storing a lot of carbon in the small box (a bay) may cause the local ecosystem to cross a tipping point, whereas spreading out in the large box (the rest of the ocean) may avoid this, while still causing ecosystem damages. The model gives rise to two different steady state solutions. A “destroy” steady state, where the tipping point in the small ocean box has been crossed, and a “diffuse” steady state without destruction. We analytically and numerically study the optimal amount of carbon stored, and the optimal distribution of carbon sequestration across the two boxes.

    Description: Article A potential drug should specifically interact with its intended target in order to limit unwanted side effects. Here, the authors fabricate a biodegradable polymer nanoparticle with a fluorescent hepatic uptake transporter ligand to achieve targeted in vivo siRNA delivery and imaging of delivery.
