A carbon central bank (CCB) that translates carbon removals into allowances would transform the European Union Emissions Trading System (EU ETS) from a fiat allowance to a gold standard system, ensuring unchanged net emissions on the path to net-zero greenhouse gas (GHG) targets. Meeting such...

The 2030 Agenda for Sustainable Development includes a set of 17 sustainable development goals (SDG) with 169 specific targets. As such, it could be a step forward in achieving efficient governance and policies for global sustainable development. However, the current indicator framework with its...

[Einleitung] Der Begriff Climate Engineering (CE) fasst verschiedene Technologien zusammen, mit denen bewusst in das Klimasystem der Erde eingegriffen wird, um den anthropogenen Klimawandel zu begrenzen. Dabei lassen sich die CE-Technologien von den herkömmlichen Vermeidungs- und...

Under the European Union Emissions Trading System (EU ETS), operators must surrender allowances corresponding to the emissions of greenhouse gases (GHG) from their installations. The supply of allowances in the EU ETS decreases linearly and, all else equal, is expected to end around 2057. An...

Christoph M. Schmidt, RWI und Ruhr-Universität Bochum, sieht in der Ratspräsidentschaft Deutschlands eine Möglichkeit, einen Neuaufbruch der europäischen Klimapolitik einzuleiten, mit einem einheitlichen und umfassenden CO2-Preis als Leitinstrument des European Green Deal. Dass die...

Intentionally removing carbon from the atmosphere with negative emission technologies (NETs) will be important to achieve net-zero emissions by mid-century and to limit global warming to 2 °C or even 1.5 °C (IPCC 2018). Model scenarios that consider NETs as part of mitigation pathways are...

To maintain the chance of keeping the average global temperature increase below 2°C and to limit long‐term climate change, removing carbon dioxide from the atmosphere (carbon dioxide removal, CDR) is becoming increasingly necessary. We analyze optimal and cost-effective climate policies in...

Selecting appropriate indicators is essential to aggregate the information provided by climate model outputs into a manageable set of relevant metrics on which assessments of climate engineering (CE) can be based. From all the variables potentially available from climate models, indicators need...

Increasing attention is being given to the option of engineering the climate via Solar Radiation Management (SRM) as a potential component in future climate policies. We set up a quantitative model to analyze efficient levels of SRM deployment against the climatic and economic background...

Most states have implemented quite strict measures designed to slow down the spread of the coronavirus among their populations. For most sectors, these measures have resulted in a significant reduction of economic activity, output, and hence also output-related emissions. Commitment to these...
