While the international community has agreed on the long-term target of limiting global warming to no more than 2°C above pre-industrial levels, only a few concrete climate policies and measures to reduce greenhouse gas (GHG) emissions have been implemented. We use a set of three global...

Governments worldwide have agreed that international climate policy should aim to limit the increase of global mean temperature to less than 2oC with respect to pre-industrial levels. The purpose of this paper is to analyse the emission reductions and related energy system changes in various...

This paper proposes a forward-looking metric of transition risk that relates financial performance and incremental carbon costs at the firm level. To this end, we use a consistent dividend discount framework augmented with emission costs of firms and climate scenario projections from four...

Deutsch-französischer Neuanfang in der militärischen Zusammenarbeit. Wie kann - rechtzeitig zum 40. Jahrestag des Elysée-Vertrages - dem deutsch-französischen Verhältnis und zugleich auch der Europäischen Sicherheits- und Verteidigungspolitik (ESVP) ein neuer Schub gegeben werden? Durch...

Carbon prices in the EU emissions trading system (EU ETS) are a key instrument driving Europe’s decarbonization. Between 2017 and 2021, they surged tenfold, exceeding 80 €/tCO2 and reshaping investment decisions across the electricity and industry sectors. What has driven this increase is an...

The transport sector is a crucial bottleneck in the decarbonization challenge. To study the sector's decarbonization potential in the wider systems perspective, we couple a large-scale integrated assessment model, Regionalized Model of INvestments and Development (REMIND), to a detailed...

Transportation accounts for a substantial share of CO2 emissions, and decarbonizing transport will be necessary to limit global warming to below 2êC. Due to persistent reliance on fossil fuels, it is posited that transport is more difficult to decarbonize than other sectors. We test this...

Lemoine and Rudik (2017) argue that it is efficient to delay reducing carbon emissions, because there is substantial inertia in the climate system. However, this conclusion rests upon misunderstanding the relevant climate physics: there is no substantial lag between CO2 emissions and warming,...

Mitigation-Process Integrated Assessment Models (MP-IAMs) are used to analyze long-term transformation pathways of the energy system required to achieve stringent climate change mitigation targets. Due to their substantial temporal and spatial aggregation, IAMs cannot explicitly represent all...

Auf dem Weltklimagipfel in Kopenhagen im Dezember 2009 wird ein globales Klimaabkommen verhandelt. Können dort Strukturen geschaffen werden, die einen effizienten und kostengünstigen Klimaschutz ermöglichen? Entscheidend sei es, nach Meinung von Hubertus Bardt, Institut der deutschen...
