An Effective Federal Climate Change Act Needs Leading Indicators

To reach the climate targets, the course towards a climate-neutral society must be set now. However, the current monitoring instruments in the Climate Change Act do not provide sufficient information to policymakers and society on the effectiveness of policy instruments and programs, as they focus exclusively on greenhouse gas reduction targets, which are subject to uncertainty. Moreover, they only ...

Does Green Public Procurement Trigger Environmental Innovations?

Green public procurement has gained high political priority and is argued to be an effective demand-side policy to trigger environmental innovations. However, the empirical evidence on its innovation impact is limited. We construct a novel firm-level dataset to investigate the effect of winning public procurement tenders with additional environmental award criteria on firms’ introduction of environmental ...

Impacts of Power Sector Model Features on Optimal Capacity Expansion: A Comparative Study

The transition towards decarbonized energy systems requires the expansion of renewable and flexibility technologies in power sectors. Many powerful tools exist to find optimal capacity expansion. In a stylized comparison of six models, we evaluate the capacity expansion results of basic power sector technologies. The technologies under investigation include base- and peak load power plants, electricity ...

The Implication of the Paris Targets for the Middle East through Different Cooperation Options

The core of the 36th round of the Energy Modeling Forum project shows that it is more likely that major fossil-fuel exporters, such as the Middle East, are highly affected because of the decrease in fossil-fuel extractions required for the worldwide fulfillment of the Paris agreement. We employ a multi-region, multi-sector computable general equilibrium model of global trade and energy to examine the ...

How Can Solar Geoengineering and Mitigation Be Combined under Climate Targets?

So far, scientific analyses have mainly focused on the pros and cons of solar geoengineering or solar radiation management (SRM) as a climate policy option in mere isolation. Here, we put SRM into the context of mitigation by a strictly temperature-target-based approach. As the main innovation, we present a scheme that extends the applicability regime of temperature targets from mitigation-only to ...

A Scheme for Jointly Trading off Costs and Risks of Solar Radiation Management and Mitigation under Long-Tailed Climate Sensitivity Probability Density Distributions

Side effects of “solar-radiation management” (SRM) might be perceived as an important metric when society decides on implementing SRM as a climate policy option to alleviate anthropogenic global warming. We generalize cost-risk analysis that originally trades off expected welfare loss from climate policy costs and risks from transgressing climate targets to also include risks from applying SRM. In ...

Chances and Barriers for Germany’s Low Carbon Transition: Quantifying Uncertainties in Key Influential Factors

With the energy sector being one of the largest sources of global greenhouse-gas emissions, a swift change in the ways of energy generation and consumption is needed for a fulfilment of climate goals. But while the existence of global warming and the resulting need for action are widely agreed upon, there is a lot of discussion around the concrete measures and their timeline. A major cause of this ...

Emission Pathways Towards a Low-Carbon Energy System for Europe: A Model-Based Analysis of Decarbonization Scenarios

The aim of this paper is to showcase different decarbonization pathways for Europe with varying Carbon dioxide (CO2) constraints until 2050. The Global Energy System Model (GENeSYS-MOD) framework, a linear mathematical optimization model, is used to compute low-carbon scenarios for 17 European countries or regions. The sectors power, low- and high- temperature heating, and passenger and freight transportation ...

Climate Neutrality Requires Coordinated Measures for High Quality Recycling

For Europe to reach climate neutrality by mid-century, it needs to move toward a circular economy. Waste avoidance, reuse, and recycling save primary resources and avoid emissions in the production of basic materials like steel, cement, and plastics. Without exploring circular economy potentials, switching production to climate-neutral processes alone would result in significant costs and tremendous ...

Optimal Discounts in Green Public Procurement

We consider a Green Public Procurement setting where the procurer provides a bid discount to environment-friendly technologies to foster their use. We assume that, before the auction, firms may switch to green technology via a publicly observable costly investment. We show that investment acts as a signaling device. This mitigates the effect of incomplete information on firms’ costs, thereby triggering ...
