This paper examines how optimal renewable energy (RE) support (RES) policies need to be adjusted to account for carbon prices. We show theoretically and empirically that changing carbon prices requires adjusting RE production subsidies due to two different motives: First, RE premiums need to be...

Electricity generation based on renewable energy (RE) sources such as wind and solar replace the most expensive generators that often rely on fossil fuels. In response to RE promotion, wholesale electricity prices and carbon emissions are therefore expected to decrease. In interconnected...

Accounting for nearly 8% of global annual carbon dioxide (CO2) emissions, the cement industry is considered difficult to decarbonize. While a sizeable number of abatement levers for Portland cement production are technologically ready for deployment, many are still viewed as prohibitively...

Carbon emissions from German manufacturing have increased over the past decade, while carbon intensity (emissions per Euro of gross output) has declined only slightly. We decompose changes in emissions between 2005 and 2017 into scale, composition (changes in the mix of goods produced) and...

Drastic emission reductions are necessary to combat climate change. However, despite several climate policies, carbon emissions from German manufacturing have actually increased between 2005 and 2017. In this paper, we provide evidence of how the policy mix overall has affected the German...

International carbon markets are frequently propagated as an efficient instrument for reducing CO2 emissions. We argue that such markets, despite their desirable efficiency properties, might not be in the best interest of governments who are guided by strategic considerations in negotiations. We...

It is widely believed that an environmental tax (price regulation) and cap-and-trade (quantity regulation) are equally efficient in controlling pollution when there is no uncertainty. We show that this is not the case if some consumers (firms, local governments) are morally concerned about...

Das Instrument des Emissionshandelssystems (EHS) wird von Umweltökonom:innen an prominenter Stelle zur Bewältigung der ökologischen Krisen sowohl im wissenschaftlichen Diskurs als auch in der Politikberatung empfohlen. Wir arbeiten drei implizite normative Prämissen des Lehrbuchmodells eines...

We study the effect of a state level mandate on renewable heating technologies on the housing market. The mandate requires a minimum share of 10 % renewable energy sources when changing the heating system in the existing building stock. As renewable energy sources are still more expensive than...

The cost and revenue earnings potential of alternative power generation sources has shifted considerably in recent years. Here we introduce the concept of Levelized Profit Margins (LPM) to capture the changing unit economics of both intermittent and dispatchable generation technologies. We apply...
