Langfristig werden Speicher wichtig: Fünf Fragen an Wolf-Peter Schill

Impulse für die Klimapolitik im Koalitionsvertrag

Das Ziel der Bundesregierung ist es laut Koalitionsvertrag, "die Erderwärmung auf maximal zwei Grad Celsius zu begrenzen und Deutschlands Vorreiterrolle beim Klimaschutz beizubehalten". Zum Erreichen dieses Ziels sollen die deutschen Treibhausgasemissionen bis zum Jahr 2020 um 40 Prozent gegenüber 1990 reduziert werden. Der Artikel erörtert die ökonomische Rechtfertigung für solch eine unilaterale ...

Innovation in Concentrating Solar Power Technologies: A Study Drawing on Patent Data

Better understanding the innovative process of renewable energy technologies is important for tackling climate change. Though concentrating solar power is receiving growing interest, innovation studies so far have explored innovative activity in solar technologies in general, ignoring the major differences between solar photovoltaic and solar thermal technologies. This study relies on patent data to ...

Innovative Activity in Wind and Solar Technology: Empirical Evidence on Knowledge Spillovers Using Patent Data

This paper studies technological change in renewable energies, providing empirical evidence on the determinants of innovative activity with a special emphasis on the role of knowledge spillovers. We investigate two major renewable energy technologies - wind and solar - across a panel of 21 OECD countries over the period 1978 to 2004. Spillovers may occur at the national level, either within the same ...

Commitments through Financial Options: An Alternative for Delivering Climate Change Obligations

Governments willing to commit themselves to maintain carbon prices at or above a certain level face the challenge that their commitments need to be credible both for investors in low-carbon technology and for foreign governments. This article argues that governments can make such commitments by issuing long-term put option contracts on the price of CO2 allowances. This mechanism gives investors the ...

Understanding the Roles and Interactions of International Cooperation on Domestic Climate Policies: Editorial

Introduction: The United Nations Framework Convention on Climate Change defines the principle of common but differentiated responsibility (Art. 4.1 of UNFCCC). It is the common responsibility of all countries to pursue mitigation actions so as to achieve climate stabilization. The differentiated nature of historic responsibility, capabilities and economic situation creates a responsibility for developed ...

Policy Targets: Lessons for Effective Implementation of Climate Actions

Policy targets are used to improve the implementation of domestic and international actions, in a national context and in international frameworks. But how can domestic and international experience be useful for climate policy? Case studies point to the value of defining policy targets more broadly than final outcomes, which in the case of climate policy are CO2 emission reductions. There is a need ...

A History of Conditionality: Lessons for International Cooperation on Climate Policy

This article surveys the experience of conditionality provisions applied by the World Bank, the IMF, bilateral donors, and the European Union's accession process. Ownership is essential for effective cooperation and requires domestic climate policies to be country-driven and decision-making to be equitable. Bilateral cooperation allows for a direct exchange of expertise and long-term relationships. ...

Energie- und Klimaschutzpolitik: USA holen langsam auf

Vor dem kommenden UN-Klimagipfel in Kopenhagen blickt die Welt vor allem auf die USA. Sie sind neben China mit Abstand der größte Emittent von Treibhausgasen. Spürbare Fortschritte beim globalen Klimaschutz setzen einen erheblichen Beitrag der Amerikaner voraus. Spielraum für eine deutliche Senkung der Emissionen ist vorhanden. So ist der Energieverbrauch pro Kopf in den USA immer noch etwa doppelt ...
