Open AccessSRM on the table: the role of geoengineering for the stability and effectiveness of climate coalitions
Geoengineering, including solar radiation management (SRM), has received increasing scrutiny due to the rise of climate extremes and slow progress in mitigating global carbon emissions. This climate policy opt...

Low-emission pathways in 11 major economies: comparison of cost-optimal pathways and Paris climate proposals
In order to evaluate the effectiveness of climate policy, it is important to understand emission trends and policies at the national level. The 2015 Paris Agreement includes (Intended) Nationally Determined Co...

The influence of economic growth, population, and fossil fuel scarcity on energy investments
This paper examines the dynamics of energy investments and clean energy Research and Development (R&D) using a scenario-based modeling approach. Starting from the global scenarios proposed in the RoSE model en...

Article
Will economic growth and fossil fuel scarcity help or hinder climate stabilization?
We investigate the extent to which future energy transformation pathways meeting ambitious climate change mitigation targets depend on assumptions about economic growth and fossil fuel availability. The analys...

Innovation benefits from nuclear phase-out: can they compensate the costs?
This paper investigates whether an inefficient allocation of abatement due to constraints on the use of currently available low carbon mitigation options can promote innovation in new technologies and have a p...

Harmonization vs. fragmentation: overview of climate policy scenarios in EMF27
This paper synthesizes results of the multi-model Energy Modeling Forum 27 (EMF27) with a focus on climate policy scenarios. The study included two harmonized long-term climate targets of 450 ppm CO2-e (enforced ...

Open AccessModeling meets science and technology: an introduction to a special issue on negative emissions
This article introduces the Climatic Change special issue dedicated to negative emissions technologies, also known as carbon dioxide removal (CDR) from the atmosphere. CDR is the only class of mitigation optio...

Open AccessDirect air capture of CO2 and climate stabilization: A model based assessment
This paper provides a novel assessment of the role of direct air capture of CO2 from ambient air (DAC) on the feasibility of achieving stringent climate stabilization. We use the WITCH energy-economy-climate mode...

Article
Time to act now? Assessing the costs of delaying climate measures and benefits of early action
This paper compares the results of the three state of the art climate-energy-economy models IMACLIM-R, ReMIND-R, and WITCH to assess the costs of climate change mitigation in scenarios in which the implementat...

Article
The value of technology and of its evolution towards a low carbon economy
This paper assesses the economic value associated with the development of various low-carbon technologies in the context of climate stabilization. We analyze the impact of restrictions on the development of sp...

Technology innovation and diffusion in “less than ideal” climate policies: An assessment with the WITCH model
This paper examines the dynamics of innovation in low-carbon energy technologies distinguishing between research and development and technology diffusion as a response to alternative climate policies. We asses...

Open AccessCounting only the hits? The risk of underestimating the costs of stringent climate policy
This paper warns against the risk of underestimating the costs—and the uncertainty about the costs—of achieving stringent stabilization targets. We argue that a straightforward review of integrated assessment ...

Open AccessA Chinese commitment to commit: can it break the negotiation stall?
Preparatory talks to the next round of negotiations seem to indicate that a comprehensive agreement to mitigate climate change will not be easily attainable, despite the intentions of the US administration and...

Delayed action and uncertain stabilisation targets. How much will the delay cost?
Despite the growing concern about actual on-going climate change, there is little consensus on the scale and timing of actions needed to stabilise the concentrations of greenhouse gases. Many countries are unw...
