Time-Consistent Carbon Pricing: The Role of Carbon Contracts for Differences

Carbon pricing decisions by governments are prone to time-inconsistency, which causes the private sector to underinvest in emission-reducing technologies. We show that incentives for decarbonization can be improved if complementing carbon pricing with carbon contracts for differences, where the government commits to pay a fixed carbon price level to the investors. We derive conditions under which the ...

EU ETS up to 2030: Adjusting the Cap in Light of the IPCC1.5°C Special Report and the Paris Agreement: Ressortforschungsplan

Wir leiten ein mit dem Pariser Übereinkommen kompatibles EU-ETS-Budget auf Basis von Kosteneffizienzkriterien her mit dem Ziel, die globale Erwärmung mit einer Wahrscheinlichkeit von 50 bis 66% auf 1,5 Grad Celsius zu begrenzen und übersetzen es in einen Pfad der Cap-Reduktion. Unsere Berechnungen ergeben ein Budget von ca. 30 Gt CO2e für das EU ETS für 2016-2050. Unter aktuellen ETS-Parametern werden ...

Technology Policy and Market Structure: Evidence from the Power Sector

We show how policies to trigger clean technologies change price competition and market structure. We present evidence from electricity markets, where regulators have implemented different policies to subsidize clean energy. Building on a multi-unit auction model, we show that currently applied subsidy designs either foster or attenuate competition. Fixed, price-independent output subsidies decrease ...

Between Stranded Assets and Green Transformation: Fossil-Fuel-Producing Developing Countries Towards 2055

Climate-related asset stranding refers to the depreciation of assets – such as resource reserves, infrastructure, or industries – resulting from the unanticipated changes, such as the tightening of climate policies. Although developing countries – especially fossil-fuel exporters – may be most concerned by this issue, its analysis in development (economics) has so far been limited.We aim at enhancing ...

Atomkraft international: Ausbaupläne von Newcomer-Ländern vernachlässigbar

Atomkraft spielt in der globalen Primärenergieversorgung mit 4,4 Prozent eine geringe und rückläufige Rolle. Der aktuelle Kraftwerkspark ist überaltert, ca. 200 Abschaltungen im kommenden Jahrzehnt stehen lediglich 46 Neubauprojekte gegenüber. Dennoch verbreitet die Atomwirtschaft, insbesondere die World Nuclear Association (WNA), das Narrativ eines großen Interesses vieler Länder an der Neu-Einführung ...

Nuclear Power Worldwide: Development Plans in Newcomer Countries Negligible

At just 4.4 percent, the contribution made by nuclear power to meeting the world’s primary energy requirements is marginal and on the decline. The current nuclear power fleet is outdated with around 200 plants due to be phased out over the next ten years compared to as few as 46 new nuclear power plants under construction worldwide. Yet the nuclear industry, particularly the World Nuclear Association ...

Energy Transition Pathways to a Low-carbon Europe in 2050: the Degree of Cooperation and the Level of Decentralization

In the framework of the Paris Agreement, the European Union (EU) will have to firmly set decarbonization targets to 2050. However, the viability on these targets is an ongoing discussion. The European Commission has made several propositions for energy and climate “roadmaps”. In this regard, this paper contributes by analyzing alternative pathways derived in a unique modelling process. As part of the ...
