Abstract:
Efforts to assess the possibilities for decoupling economic growth from negative environmental impacts have examined their historical relationship, with varying and inconclusive results. Part of the problem is ambiguity about definitions of environmental impacts, e.g. whether to use territorial or consumption-based measures of environmental impact. This paper shows that ambiguities arising from definitional changes to GDP are sufficiently large to affect the outcomes. I review the history of structural revisions to GDP using the example of the United States, and on international comparisons of purchasing power parity, compare decoupling results using various historical definitions of GDP on the same environmental indicator, and demonstrate that changing the GDP data vintage does impact decoupling results in qualitatively important ways, with and without purchasing power parity. Inconsistencies in economic measurement introduce an additional layer of ambiguity into historical decoupling evidence and model projection into the future. To advance debate and be clear about scenario assumptions, rigorous reporting of GDP definitions used and the sharing of data vintage for subsequent comparison and replication are urgently needed.

Abstract:
The distribution of ownership of transition risk associated with stranded fossil-fuel assets remains poorly understood. We compute global stranded assets of US$1.4 trillion in the upstream oil and gas sector as expectations change to be consistent with stated climate policies. We trace the equity risk ownership from these 43,439 assets through a global equity network of 1.8 million companies to their ultimate owners. Most of the market risk falls on private investors, overwhelmingly in OECD countries, including substantial exposure through pension funds. Financial markets are exposed to a US$690 billion correction, comparable to the mispricing that triggered the 2007-08 crisis. The ownership distribution also shows the large stake OECD investors have in the continued operation of fossil-fuel facilities incompatible with climate change mitigation goals.

Abstract:
The transition to a low‐carbon economy will entail a large‐scale structural change. Some industries will have to expand their relative economic weight, while other industries, especially those directly linked to fossil fuel production and consumption, will have to decline. Such a systemic shift may have major repercussions on the stability of financial systems, via abrupt asset revaluations, defaults on debt, and the creation of bubbles in rising industries. Studies on previous industrial transitions have shed light on the financial transition risks originating from rapidly rising “sunrise” industries. In contrast, a similar conceptual understanding of risks from declining “sunset” industries is currently lacking. We substantiate this claim with a critical review of the conceptual and historical literature, which also shows that most literature either examines structural change in the real economy, or risks to financial stability, but rarely both together. We contribute to filling this research gap by developing a consistent theoretical framework of the drivers, transmission channels, and impacts of the phase‐out of carbon‐intensive industries on the financial system and on the feedback from the financial system into the rest of the economy. We also review the state of play of policy aiming to protect the financial system from transition risks and spell out research implications.

4. Inequality in Energy Consumption: Statistical Equilibrium or a Question of Accounting Conventions?

Abstract:
Mitigating climate change requires information about the inequality in energy consumption. Recent contributions (Banerjee and Yakovenko, 2010; Lawrence et al., 2013; Yakovenko, 2010, 2013) have studied energy inequality through the lens of maximum entropy. They claim a weighted international distribution of total primary energy demand should approach a Boltzmann-Gibbs maximum entropy equilibrium distribution in the form of an exponential distribution, implying convergence to a Gini coefficient of 0.5 from above. The present paper challenges the validity of this claim and critically discusses the applicability of statistical equilibrium reasoning to economics from the viewpoint of social accounting. It is shown that the exponential distribution is only a robust candidate for a statistical equilibrium of energy inequality when employing one particular accounting convention for energy flows, the substitution method. But this method has become problematic with a higher renewable share in the international energy mix, and no other accounting method supports the claim of a convergence to a 0.5 Gini. We conclude that the findings based on maximum entropy reasoning are sensitive to accounting conventions and critically discuss the epistemological implications of this sensitivity for the use of maximum entropy approaches in social sciences.
