This paper presents results from a model intercomparison exercise among regionalized global energy-economy models conducted in the context of the RECIPE project. The economic adjustment effects of long-term climate policy aiming at stabilization of atmospheric CO2 concentrations at 450 ppm are...

Die Zweifel wachsen, ob allein die Höhe und der Verlauf des Bruttoinlandsprodukts ausreichen, den Wohlstand einer Gesellschaft zu messen. Um diese Frage zu diskutieren, hatte der Deutsche Bundestag Anfang 2011 eine Enquete-Kommission eingerichtet, die im Frühjahr 2013 ihren Abschlussbericht...

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...

Compared to most countries, China's value-added tax (VAT) system is not neutral and makes it less advantageous to export a product than to sell it domestically, as exporters may not receive a complete refund on the domestic VAT they have paid on their inputs. However, the large and frequent...

Border adjustments are currently discussed to limit the possible adverse impact of climate policies on competitiveness and carbon leakage. We discuss the main choices that will have to be made if the European Union implements such a system alongside with the EU ETS. Although more analysis is...

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...
