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.

Begleitende Evaluierung des Investitionsgesetzes Kohleregionen (InvKG) und des STARK-Bundesprogramms ‒ Zweiter Zwischenbericht vom 31.10.2024

Matthias Brachert Katja Heinisch Oliver Holtemöller Florian Kirsch Uwe Neumann Michael Rothgang Torsten Schmidt Christoph Schult Anna Solms Mirko Titze

in: IWH Studies, No. 1, 2025

Abstract

<p><strong>Gutachten im Auftrag des Bundesministeriums für Wirtschaft und Klimaschutz</strong></p> <p>Das Klimaschutzgesetz (KSG) sieht eine Reduktion der deutschen Treibhausgasemissionen bis zum Jahr 2030 um 65 Prozent gegenüber den Emissionen im Jahr 1990 vor. Der Ausstieg aus der thermischen Verwertung der Kohle (vor allem der Braunkohle) leistet einen substanziellen Beitrag zum Erreichen dieser Ziele. Der Kohleausstieg stellt die Braunkohlereviere (und die Standorte der Steinkohlekraftwerke) jedoch vor strukturpolitische Herausforderungen. Um den Strukturwandel in diesen Regionen aktiv zu gestalten, hat der Bundestag im August 2020 mit Zustimmung des Bundesrats das Strukturstärkungsgesetz Kohleregionen (StStG) beschlossen. Über dieses Gesetz stellt der Bund bis zum Jahr 2038 Finanzhilfen von 41,09 Mrd. Euro zur Verfügung. Im Fokus der Politikmaßnahmen stehen verschiedene Ziele, vor allem gesamtwirtschaftliche (Wertschöpfung, Wachstum, Steueraufkommen), wettbewerbliche (Produktivität), arbeitsmarktpolitische (Beschäftigung, Beschäftigungsstrukturen), verteilungspolitische (regionale Disparitäten) sowie klimapolitische (Treibhausgasreduzierung, Nachhaltigkeit). Die im StStG vorgesehenen strukturpolitischen Interventionen umfassen ein breites Maßnahmenbündel. Das Gesetz fordert eine begleitende wissenschaftliche Evaluierung des Gesetzes. Bei dem vorliegenden Bericht handelt es sich um das zweite Dokument in diesem Evaluierungszyklus. Der erste Bericht liegt seit Juni 2023 vor und präsentierte ein erstes Lagebild nach dem Start der im Rahmen des Investitionsgesetzes Kohleregionen (InvKG) und des STARK-Bundesprogramms geplanten Maßnahmen. Nachdem nunmehr zahlreiche Maßnahmen in die Umsetzung gehen, nimmt der Strukturwandel an Fahrt auf. Der aktuelle Bericht nimmt eine Aktualisierung vor und erweitert Aussagen zu deren möglichen Effekten. Auch für diesen Bericht bleibt zu berücksichtigen, dass viele der geplanten Maßnahmen noch nicht oder gerade erst begonnen haben, was bei einer fast zwanzigjährigen Laufzeit des Programms durchaus naheliegend ist. Die in diesem Bericht vorgelegten empirischen Analysen basieren auf dem Datenstand vom 30.06.2024, also fast vier Jahre nach Programmstart.</p>

Ecological Preferences and the carbon Intensity of Corporate Investment

Michael Koetter Felix Noth

in: IWH Discussion Papers, No. 2, 2025

Abstract

<p>Lowering carbon intensity in manufacturing is necessary to transform current production technologies. We test if local agents’ preferences, revealed by vote shares for the Green party during local elections in Germany, relate to the carbon intensity of investments in production technologies. Our sample comprises all investment choices made by manufacturing establishments from 2005-2017. Our results suggest that ecological preferences correlate with significantly fewer carbon-intensive investment projects while investments stimulating growth and reducing carbon emissions increase by 14 percentage points. Both results are more distinct in federal states where the Green Party enjoys political power and local ecological preferences are high.</p>

The German Energy Crisis: A TENK-based Fiscal Policy Analysis

Alexandra Gutsch Christoph Schult

in: IWH Discussion Papers, No. 1, 2025

Abstract

<p>We study the aggregate, distributional, and welfare effects of fiscal policy responses to Germany’s energy crisis using a novel Ten-Agents New-Keynesian (TENK) model. The energy crisis, compounded by the COVID-19 pandemic, led to sharp increases in energy prices, inflation, and significant consumption disparities across households. Our model, calibrated to Germany’s income and consumption distribution, evaluates key policy interventions, including untargeted and targeted transfers, a value-added tax cut, energy tax reductions, and an energy cost brake. We find that untargeted transfers had the largest short-term aggregate impact, while targeted transfers were most cost-effective in supporting lower-income households. Other instruments, as the prominent energy cost brake, yielded comparably limited welfare gains. These results highlight the importance of targeted fiscal measures in addressing distributional effects and stabilizing consumption during economic crises.</p>

A Multi-Model Assessment of Inequality and Climate Change

Marie Young-Brun et al.

in: Nature Climate Change, October 2024

Abstract

<p>Climate change and inequality are critical and interrelated defining issues for this century. Despite growing empirical evidence on the economic incidence of climate policies and impacts, mainstream model-based assessments are often silent on the interplay between climate change and economic inequality. For example, all the major model comparisons reviewed in IPCC neglect within-country inequalities. Here we fill this gap by presenting a model ensemble of eight large-scale Integrated Assessment Models belonging to different model paradigms and featuring economic heterogeneity. We study the distributional implications of Paris-aligned climate target of 1.5 degree and include different carbon revenue redistribution schemes. Moreover, we account for the economic inequalities resulting from residual and avoided climate impacts. We find that price-based climate policies without compensatory measures increase economic inequality in most countries and across models. However, revenue redistribution through equal per-capita transfers can offset this effect, leading to on average decrease in the Gini index by almost two points. When climate benefits are included, inequality is further reduced, but only in the long term. Around mid-century, the combination of dried-up carbon revenues and yet limited climate benefits leads to higher inequality under the Paris target than in the Reference scenario, indicating the need for further policy measures in the medium term.</p>
