This paper aims to develop a risk assessment framework that addresses both the complexities of the risk landscape that green transition portfolios face, but is recognizable and easily understandable by stakeholders. For this purpose, we build upon the framework of NASA Technology Readiness Levels (TRLs). This study analyzes six existing readiness levels framework that are held towards uncertainty factors from the Green Transition. The TRL scale are coupled with Risk, Uncertainty, and Ignorance to score the individual level of uncertainty. The paper ends with suggestion for further studies.

Sustainable finance is often discussed as a solution to the climate crisis, but its impacts are limited and its discourse focuses on mobilising private investments through public de-risking, without considering direct government action. We argue that this is due to an implicit reference to mainstream economic theory assuming that an active state leads to time inconsistency problems and crowding-out effects. However, these assumptions have been sufficiently refuted as public investments may actually crowd-in private capital. We therefore propose a paradigm shift towards what we call Public Sustainable Finance, aimed at empowering the role of the state in the green transition on the discursive, policy, and political economy levels. Studying the case of Germany, we show how Public Sustainable Finance can be introduced despite tight fiscal regimes. To this end, we propose that the Climate- and Transformation Fund be given its own borrowing powers. By borrowing an average of 23 billion euros annually from 2024 to 2030, the existing financing gap that has been exacerbated following the November 2023 constitutional court ruling can be closed, enabling a more rapid and effective green transition.

Increased focus on sustainability significantly impacts product development portfolio management in organizations. This paper focuses on the significant unaccommodated uncertainty caused by the green transition for current mid- and long-term portfolio management processes. These uncertainties arise in areas such as the regulatory environment, market demands, and technical capabilities. This paper makes four contributions: First, current product portfolio management literature is mostly employing deterministic practices. Uncertainties are incompletely addressed, and current methods fail to address the deep uncertainties of the green transition. Second, building a literature-based conceptual framework of the sources of uncertainty in 6 areas: Business Models, Technology, Regulation and Legislation, Finance and Insurance, Market and Consumer, and Organizational Context. Third, preliminary empirical evidence supports the usefulness of our model for product development portfolio management. Fourth, concluding with a suggested empirical research agenda to develop a deeper understanding of challenges towards method and theory development to support the green transition on the portfolio management level.

This Article discusses existing WTO rules on subsidies and state enterprises, relevant caselaw and reform prospects in light of key geopolitical developments and changes in the global economy emerging in the aftermath of the Covid-19 pandemic. Following a general introduction, the Article critically analyzes present WTO rules on industrial subsidies, focusing inter alia on the new problems raised by activist industrial policies pursued by global trading powers, foreign subsidization, the climate change shock and environmental exigencies. It then shifts attention to the application of WTO rules on subsidies to the state sector and the increasing demands for new international trade rules on non-subsidies measures to address the negative spillover effects on trade from government influence on state-owned enterprises (SOEs). With respect to each of these matters, the Article first clarifies the terms of the problem in relation to existing WTO rules and caselaw, and next examines the question of how, and to what extent, “deeper” free trade agreements (FTAs)—those that experts designate as models for WTO reforms on the matter—establish new rules that permit to adequately address the trade concerns raised by SOEs’ commercial and financial activities. Based on this multi-layered analysis, the article concludes by examining prospects of reform of WTO rules on state interventionism.

This study examines how the climate litigation approach builds pathways to face climate emergency. In light of recent jurisdictional developments, this article underlines the links between legislation, litigation, and public policies to trace ways, progress and obstacles to face it. Those emergent dynamics contribute to build a lasting and sustainable climate change legal regime. Intertwining the different climate disputes in the world and the progress made through the elaboration of different climate laws allow to have a panoramic visibility on this new mode of climate governance which appears in filigree today all over the world and especially in France.

The paper compares the effects of market-based (M-B) and command-and-control (C&C) climate policies on the direction of technical change and the prevention of environmental disasters. Drawing on a model of endogenous growth and directed technical change, we show that M-B policies (carbon taxes and subsidies toward clean sectors) suffer from path dependence and exhibit bounded window of opportunities: delays in their implementation make them ineffective both in redirecting technical change, (i.e. triggering a transition toward clean energy) and in avoiding environmental catastrophes. On the contrary, we find that C&C interventions are favored by path dependence and guarantee policy effectiveness irrespectively of the timing of their introduction. As the hypothesis of path dependence in technological change has received vast empirical support and it is a key feature of many models of growth, we argue that C&C policies should be seen as a valuable and non-equivalent alternative to M-B interventions.
