Emission-free hydrogen (H2) is crucial to decarbonize energy supply and to tackle the climate crisis. To unlock the potential of H2, pipelines infrastructures and related investments are required to enable trade. However, it is uncertain what future H2 infrastructure will be needed. The paper...

We estimate the long-run effect of a uniform carbon tax on energy consumption by using a new and unique dataset in which effective tax rates of OECD countries are calculated in terms of carbon dioxide emissions. The effective tax rates account for the widely discussed tax deductions for specific...

This paper investigates the impacts of the Swiss CO2 levy on households' heating demand. Using a difference-in-differences approach combined with inverse probability of treatment weighting, we test whether the 2016 carbon tax rate increase had a short-term impact on Swiss households' heating...

The expansion of digital payment services like retail Central Bank Digital Currencies (rCBDCs) built on innovative ICT infrastructure, notably datacenters, raises questions regarding potential environmental consequences due to electricity consumption. The design of such systems is critical for...

The European Union (EU) has redefined the energy sphere in Europe over the last three decades. Transnational policies targeting liberalization and integration, energy efficiency, renewables, carbon pricing, and energy security have led to major steps forward in terms of a more secure,...

Our analysis is the first of its kind to explore patterns of subsidization and CO2 emissions in China’s electricity producing sector. Applying data for all power plants across China and controlling for the age, capacity and location of generating stations, we find that plants attracting a...
