The European Commission has recommended that the European Union should cut greenhouse gas emissions by 90 percent by 2040 compared to 1990. Modelling shows that this target is feasible technically and is in line with social acceptability and global fairness objectives. Achieving it will require...

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...

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...

Germany has an ambitious climate target for 2030 that cannot be achieved without reducing the high share of coal in power generation. In the face of this, the country has set up a commission to phase out coal. A UK-style carbon price floor is one of the options being considered. Yet implementing...

Germany aims to phase out coal to achieve its 2030 climate target, for which a UK-style carbon price floor is considered. But this measure comes with risks related to the uncertainty about what price level is sufficient, and the waterbed effect arising from unilateral policy under the EU-ETS....

The stringency of the EU’s Emission Trading System (ETS) is bound to be ratcheted-up to deliver on more ambitious goals as put forth in the EU’s Green Deal. Tightening the cap needs to consider the interactions with the Market Stability Reserve (MSR), which will be reviewed in 2021. Against...

The EU Green Deal calls for climate neutrality by 2050 and emission reductions of 50-55% in 2030 in comparison to 1990. Achieving these reductions requires a substantial tightening of the regulations of the EU emissions trading system (EU ETS). This paper explores how the power sector would have...

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...
