Power Sector Effects of Green Hydrogen Production in Germany

The use of green hydrogen can support the decarbonization of sectors which are difficult to electrify, such as industry or heavy transport. Yet, the wider power sector effects of providing green hydrogen are not well understood so far. We use an open-source electricity sector model to investigate potential power sector interactions of three alternative supply chains for green hydrogen in Germany in ...

WinIt – Scientific Analyses of Industrial Transformation

The project deals with scientific questions on industrial transformation towards a climate-neutral and resilient economy, covering the entire breadth of this topic. Questions on industrial transformation in Germany and beyond are formulated with a view to the EU's energy and climate policy instruments. The approach applies scientific methods throughout.  The background to the project is the very...

Leibniz-Lab "Systemic Sustainability"

The rapid loss of biodiversity and ongoing climate change are also the result of intensive agriculture. At the same time, they jeopardize agriculture and food security. The Leibniz Lab "Systemic Sustainability" brings together relevant knowledge in science and society on this fundamental challenge in order to promote the development and implementation of systemic solutions. The current socio...

Enabling Circular Economy Dynamics in the Plastics and Steel Industries: Perspectives from Multiple Stakeholders

This paper investigates the perspectives of stakeholder groups in the plastic and steel value chains on transitioning toward a circular economy (CE). Through semistructured interviews with 31 business stakeholders, we analyze business strategies, key factors, challenges and opportunities, as well as coordination and regulatory needs for a successful industry-wide CE transition. Our findings highlight ...

The Evolution of Theories of Harm in EU Merger Control

We discuss the main Theories of Harm in EU merger control and their evolution since the 1990s. We present stylised facts and trends using data extracted from EU merger decisions by natural language processing tools. EU merger policy has adapted over time, both in terms of legislation and theories of harm, as well as in terms of the investigative tools and evidence used. The introduction of the new ...

Nobody Decides for All — Modeling Incentives and Policies for Closing the Material Loop

Bridges over Troubled Waters: Climate Clubs, Alliances, and Partnerships as Safeguards for Effective International Cooperation?

Driven by the motivation to raise the ambition level of climate action and to foster the transformation of economies, current climate policy discourse revolves around ways to improve cooperation between industrialized countries and emerging economies. We identify three broad types of initiatives—multilateral-cross sectoral, multilateral, sector specific, and climate and development partnerships—and ...

Mortality Inequality in Chile

This paper analyses trends in mortality inequality in 330 Chilean communes from 1990 to 2010 for different age groups and both genders. Chile had substantial inequalities in local-level mortality rates in 1990 but by 2010 these disparities had significantly decreased, especially among infants, children and the elderly. The only exception was Chilean men aged 20–39, for whom inequality in mortality ...

Growing Clean? Directing Technological Change in Germany

The emerging net zero paradigm requires economies to go green; and Europe’s ambition is to lead the way. This requires directing technological change toward cleaner growth, which intersects with green industrial policies in the form of green innovation subsidies. Leveraging a quasi-exhaustive novel dataset on German R&D subsidies, we provide rigorous evidence on whether green R&D subsidies...

Revisiting Investment Costs for Green Steel: Capital Expenditures, Firm Level Impacts, and Policy Implications

The transition of the steel sector to carbon neutrality requires significant investment. In this study, we aim to better understand the scale of investment required for a transition to hydrogen-based steelmaking and the ability of listed steelmakers to finance this investment. First, we analyze how capital expenditures are estimated in the academic literature and compare them with reported investment ...
