A global database of measured values of Li/Mg, Mg/Ca, Sr/Ca, Ba/Ca, U/Ca and Sr-U for coral and coralline algae paleoenvironment calibrations

Calcifying marine organisms provide a valuable means to access high-resolution historical records of the marine environment captured within their skeletal geochemistry. These records are essential for comprehending the effects of human-induced climate change and reducing uncertainties in future projections. Integrating investigations across various taxa, depths, and geographic locations can help identify universal environmental proxies and serve as a basis for targeted studies in the future. Here, we provide a comprehensive georeferenced database of measured values of Li/Mg, Mg/Ca, Sr/Ca, Ba/Ca, U/Ca and Sr-U in coral and coralline algae compiled from the scientific literature (1950-2021; http://www.webofknowledge.com, accessed 2022-09-30) for the purpose of interrogating and refining global, mineralogy specific and/or taxon-specific proxies for seawater temperature and barium. We include metadata relating to the source, timing and location of each study, the methodology used, and environmental and experimental information. The dataset presents an opportunity to quantify uncertainty and test the robustness of trace and minor element proxies for past environmental conditions, of which will be of value within the fields of geochemistry, ecology, climate, and palaeobiology. Full methodology and additional information provided in Williams et al. (2024).

Introduction of a Carbon Border Adjustment Mechanism (CBAM) in the EU

The EU will introduce a carbon border adjustment mechanism (⥠CBAM⥠) on October 1, 2023. The main idea is to apply the same carbon price to imported emission-intensive goods as if they had been produced under EU carbon pricing rules (EU ETS). This is intended to prevent the relocation of domestic industry, which has to bear rising ⥠CO2⥠costs within the EU ETS, to countries without comparable carbon pricing. This would not protect the climate. The factsheet explains the objectives and functioning of the new climate protection instrument. Quelle: www.umweltbundesamt.de

Einführung eines CO2-Grenzausgleichssystems (CBAM) in der EU

Die EU führt zum 1. Oktober 2023 ein CO2-Grenzausgleichssystem (CBAM) ein. Die Grundidee besteht darin, im Ausland produzierte emissionsintensive Güter mit dem gleichen CO2-Preis zu belegen wie in der EU hergestellte Güter. Damit soll verhindert werden, dass die heimische Industrie, die im Rahmen des EU-ETS steigende CO2-Kosten zu tragen hat, in Länder ohne vergleichbare CO2-Bepreisung verlagert wird. Dies wäre nicht im Sinne des Klimaschutzes. Das Factsheet erklärt Ziele und Funktionsweise des neuen Klimaschutzinstruments. Quelle: umweltbundesamt.de

Carbon border adjustment in the EU (CBAM): relevance of foreign trade and CO2 - costs

This analysis is intended to contribute to classifying the effects of the introduction of the CBAM on the affected industrial sectors in Germany in relation to exports. It analyses the export intensity and the costs for the purchase of certificates compared to the average value of exports of the respective product group. Quelle: www.umweltbundesamt.de

CO2-Grenzausgleich in der EU (CBAM): Bedeutung von Außenhandel und CO2-Kosten

Der geplante CO2-Grenzausgleichsmechanismus der EU (CBAM) umfasst nach Vorschlag der EU- Kommission nicht die Ausfuhren aus der EU. Wenn bei der Produktion in der EU Kosten durch den Europäischen Emissionshandel (EU-ETS) entstehen und beim Export kein Ausgleich dieser Kosten vorgenommen wird, kann dies die Wettbewerbsfähigkeit europäischer Exporte senken. Die vorliegende Analyse soll helfen, die Auswirkungen des CBAM auf die betroffenen Industriebranchen in Deutschland in Bezug auf die Exporte einzuordnen. Dazu werden die Exportintensität der jeweiligen Industrieprodukte ermittelt und die Kosten für den Zukauf von Zertifikaten ins Verhältnis zum durchschnittlichen Wert der Exporte der jeweiligen Produktgruppe gesetzt.

The EU CBAM and a climate club: synergies and potential obstacles for full integration

This discussion paper analyses potential synergies between climate clubs and CBAMs. It presents a case study of the concrete proposals currently debated for implementation: 1) the EU CBAM which looks set to be adopted by the EU Council and Parliament later this year and 2) the proposal for a climate club that was adopted by the G7 at their summit in June 2022. Chapter 2 introduces the two instruments and explains how they interrelate. Chapter 3 discusses potential obstacles to a full integration of both instruments. Chapter 4 shows how product-specific standards can be a tool at the intersection of both instruments, thereby augmenting synergies between them. The paper is directed at policy makers as well as the general scientific community that conducts research on the topics described above. Quelle: www.umweltbundesamt.de

Mg, Li, Sr and B/Ca in the calcareous red alga Lithothamnion corallioides

Data showing B/Ca, Mg/Ca, Li/Ca and Sr/Ca measured in the calcareous red alga Lithothamnion coralliodes lived-collected at different sites and depths across the Mediterranean Sea (Aegadian Islands, 40 m depth; Elba, 45 m depth; Pontian Islands, 66 m depth) and in the Atlantic Ocean (Morlaix Bay, 12 m depth). Element concentrations have been measured using an Agilent ICP-QQQ 8900 quadrupole ICP-MS coupled to an Excimer laser ablation system (193 nm wavelength), at 50 μm spots crossing the algal growth direction.
