Green Transition

The green transition is a key topic of our time. In a broader sense, it describes the comprehensive change in the German and European economy towards a more sustainable, environmentally friendly and future-proof way of doing business. In a narrower sense, the green transition is understood as a process of generating energy in an increasingly greenhouse gas-neutral way.

This transition is undisputed. It is necessary to combat climate change and offers immense opportunities for innovation, growth and the creation of new jobs in Germany – provided it is strategically planned and implemented correctly.

What is the Green Transition About?

At its core, the green transition is about replacing fossil fuels with renewable energy, increasing energy efficiency and establishing a circular economy.

The green transition requires considerable investment in new technologies and infrastructure as well as adjustments to legislation and regulation. Firms need to change their production processes, develop new business models, and offer sustainable products and services.

On the one hand, economic research and policy advice support areas that are negatively affected by the green transition, such as the German coal-mining regions, which are receiving funding for structural changes. On the other hand, economic research focuses on economic sectors that are growing, such as digitalisation and robotics.

The Role of the Halle Institute in the Green Transition

This structural change affects all areas of the economy, from industry and the service sector to agriculture. Energy-intensive sectors in particular face the challenge of drastically reducing their emissions while remaining competitive.

This structural change requires innovative approaches and close cooperation between business, science and politics. The Halle Institute for Economic Research (IWH) is facing this challenge and is positioning itself at this interface with its research and policy advice.

Among other things, the researchers at the Institute analyse the economic impact of the green transition, evaluate the effectiveness of political measures, and provide important findings for the design of funding programmes and regulations. Through well-founded analyses and forecasts, they contribute to mastering the challenges of structural change and making the best use of its potential.

All of this takes place within a European and international framework: Through networked research projects, conference participation, and the exchange of visiting academics, the Halle Institute's research and policy advice are at the cutting edge. They are linked to other key topics at the institute, including research on business cycles, financial stability, productivity, and demographics.

The European Dimension of the Green Transition

The green transition offers an opportunity to successfully position Germany as a leader in sustainability and innovation. By developing and exporting green technologies and solutions, the German economy can benefit not only ecologically but also economically.

For this to succeed, however, Germany must avoid taking a unique economic path and instead proceed in a coordinated manner across Europe, as it does in other areas. The Halle Institute also advocates market-based instruments to support this process. 

According to the Halle Institute, the European Union (EU) is the key driver of the green transition, along with price incentives. In order to increase public acceptance, CO2 reductions should take place where it is most cost-effective within the EU.

In a strategy paper published on 18 June 2024, entitled “Six Points for an Efficient Green Transition” ("Sechs Punkte für eine effiziente grüne Transformation"), Reint Gropp and Oliver Holtemöller, President and Vice President of the Halle Institute, therefore state that energy production and consumption should not be regulated in a piecemeal manner. Instead, the authors recommend a set of coordinated points for the green transition that are only effective as a package.

A Multi-Model Assessment of Inequality and Climate Change

Marie Young-Brun et al.

in: Nature Climate Change, Vol. 14 (12), 2024

Abstract

Climate change and inequality are critical and interrelated issues. Despite growing empirical evidence on the distributional implications of climate policies and climate risks, mainstream model-based assessments are often silent on the interplay between climate change and economic inequality. Here we fill this gap through an ensemble of eight large-scale integrated assessment models that belong to different economic paradigms and feature income heterogeneity. We quantify the distributional implications of climate impacts and of the varying compensation schemes of climate policies compatible with the goals of the Paris Agreement. By 2100, climate impacts will increase inequality by 1.4 points of the Gini index on average. Maintaining global mean temperature below 1.5 °C reduces long-term inequality increase by two-thirds but increases it slightly in the short term. However, equal per-capita redistribution can offset the short-term effect, lowering the Gini index by almost two points. We quantify model uncertainty and find robust evidence that well-designed policies can help stabilize climate and promote economic inclusion.

Climate-resilient Economic Development in Vietnam: Insights from a Dynamic General Equilibrium Analysis (DGE-CRED)

Andrej Drygalla Katja Heinisch Christoph Schult

in: IWH Technical Reports, No. 1, 2024

Abstract

In a multi-sector and multi-region framework, this paper employs a dynamic general equilibrium model to analyze climate-resilient economic development (DGE-CRED) in Vietnam. We calibrate sector and region-specific damage functions and quantify climate variable impacts on productivity and capital formation for various shared socioeconomic pathways (SSPs 119, 245, and 585). Our results based on simulations and cost-benefit analyses reveal a projected 5 percent reduction in annual GDP by 2050 in the SSP 245 scenario. Adaptation measures for the dyke system are crucial to mitigate the consumption gap, but they alone cannot sufficiently address it. Climate-induced damages to agriculture and labor productivity are the primary drivers of consumption reductions, underscoring the need for focused adaptation measures in the agricultural sector and strategies to reduce labor intensity as vital policy considerations for Vietnam’s response to climate change.

Deutschland braucht eine klare wirtschaftspolitische Strategie

Reint E. Gropp

in: Wirtschaft im Wandel, No. 3, 2024

Abstract

Die deutsche Wirtschaft steht unter Druck, doch die aktuellen Maßnahmen der Regierung führen kaum zu einer nachhaltigen Erholung. Unternehmen sind mit Unsicherheiten konfrontiert, die Investitionen hemmen – insbesondere hinsichtlich der Energieversorgung und der damit verbundenen Kosten. Viele Betriebe schieben deshalb notwendige Investitionen auf – genau die Investitionen, die das wirtschaftliche Wachstum antreiben könnten.

Analyse der Effekte des Atomausstiegs auf die deutschen Großhandelsstrompreise 2023

Christoph Schult

in: Wirtschaft im Wandel, No. 3, 2024

Abstract

Seit dem Atomausstieg am 15. April 2023 sind die Großhandelsstrompreise in Deutschland deutlich gesunken. Innerhalb des deutschen Merit-Order-Systems galten Atomkraftwerke als die kostengünstigste Form der Stromerzeugung. Hätten die Atomkraftwerke weiterbetrieben werden können, wären die Großhandelsstrompreise für den Zeitraum vom 16. April 2023 bis zum 31. Dezember 2023 voraussichtlich um 1% bis 8% niedriger gewesen. Insbesondere im Oktober hätte der Weiterbetrieb der Atomkraftwerke die Großhandelsstrompreise gesenkt, vor allem in Zeiten hoher Stromnachfrage und geringer Verfügbarkeit erneuerbarer Energien.

Optimal Monetary Policy in a Two-sector Environmental DSGE Model

Oliver Holtemöller Alessandro Sardone

in: IWH Discussion Papers, No. 18, 2024

Abstract

In this paper, we discuss how environmental damage and emission reduction policies affect the conduct of monetary policy in a two-sector (clean and dirty) dynamic stochastic general equilibrium model. In particular, we examine the optimal response of the interest rate to changes in sectoral inflation due to standard supply shocks, conditional on a given environmental policy. We then compare the performance of a nonstandard monetary rule with sectoral inflation targets to that of a standard Taylor rule. Our main results are as follows: first, the optimal monetary policy is affected by the existence of environmental policy (carbon taxation), as this introduces a distortion in the relative price level between the clean and dirty sectors. Second, compared with a standard Taylor rule targeting aggregate inflation, a monetary policy rule with asymmetric responses to sector-specific inflation allows for reduced volatility in the inflation gap, output gap, and emissions. Third, a nonstandard monetary policy rule allows for a higher level of welfare, so the two goals of welfare maximization and emission minimization can be aligned.
