Abstract:
Recent years have seen an increasing use of environmental dynamic stochastic general equilibrium (E-DSGE) models for analyzing the macroeconomic effects of the climate crisis. This paper explores to what extent these models are fit for purpose. We identify the limitations of the benchmark E-DSGE framework and explain how these limitations restrict the ability of this framework to meaningfully capture the macroeconomics of the climate crisis. We then explain how the assumptions behind these limitations can be relaxed, but argue that simply relaxing some of these assumptions in isolation is insufficient to address the problem. We therefore call for a broader use of other macroeconomic models, such as ecological stock-flow consistent (E-SFC) and ecological agent-based (E-AB) models, that address these limitations simultaneously. We explain how these models do not suffer from the pitfalls of the E-DSGE framework and outline how they need to improve to increase their usefulness as tools that can inform macroeconomic policy making in the Anthropocene.

Abstract:
The European Union’s Green Deal, a €1 trillion, 10-year investment plan to reduce greenhouse gas emissions by 55% in 2030 (relative to 1990 levels), has been hailed as the first comprehensive plan to achieve climate neutrality at a continental scale. The Deal also constitutes the Union’s new signature mission, providing it with a new raison d’etre and a shared vision of green growth and prosperity for all. Because the stakes are high, a dispassionate, realistic look at the Green Deal is necessary to assess to what extent it reflects ‘what is politically attainable’ and to what degree it does ‘what is required’ in the face of continuous global warming. This paper considers the ambition, scale, substance and strategy of the Deal. It finds that the Green Deal falls short of ‘what is imperative’ but also of ‘what is politically possible’. By choosing to make the Green Deal dependent on global finance, the European Commission itself closes down all policy space for systemic change as well as for ambitious green macroeconomics and green industrial policies, which would enable achieving climate neutrality in a socially and economically inclusive manner. Hence, Otto von Bismarck would have been as unpersuaded by the Green Deal proposal as Greta Thunberg, who dismisses it as mere “empty words”.

Abstract:
All IPCC (2018) pathways to restrict future global warming to 1.5°C (and well below an already dangerous 2°C) involve radical cuts in global carbon emissions. Such decarbonization, while being technically feasible, may impose a ‘limit’ or ‘planetary boundary’ to growth, depending on whether or not human society can decouple economic growth from carbon emissions. Decoupling is regarded viable in global and national policy discourses on the Paris Agreement—and claimed to be already happening in real time: witness the recent declines in territorial CO2 emissions in a group of more than 20 economies. However, some scholars argue that radical de-carbonization will not be possible while increasing the size of the economy. This paper contributes to this debate as well as to the larger literature on climate change and sustainability. First, we develop a prognosis of climate-constrained global growth for 2014-2050 using the Kaya sum rule. Second, we use the Carbon-Kuznets-Curve (CKC) framework to empirically assess the effect of economic growth on CO2 emissions using measures of both territorial (production-based) emissions and consumption-based (tradeadjusted) emissions. We run panel data regressions using OECD ICIO CO2 emissions data for 61 countries during 1995-2011; to check the robustness of our findings we construct and use panel samples sourced from alternative databases (Eora; Exio; and WIOD). Even if we find evidence suggesting a decoupling of production-based CO2 emissions and growth, consumption-based CO2 emissions are monotonically increasing with per capita GDP (within our sample). We draw out the implications of these findings for climate policy and binding emission reduction obligations.

Working Paper Carbon Emissions and Economic Growth: Production-based versus Consumption-based Evidence on Decoupling MAR 2016 | ENERGY | ENVIRONMENT SHARE WORKING PAPER SERIES BY Goher-Ur-Rehman Mir Ecofys Consulting Servaas Storm Senior Lecturer of Economics, Delft University of Technology DOWNLOAD PAPER We assess the Carbon-Kuznets-Curve hypothesis using internationally consistent and comparable production-based versus consumption-based CO2 emissions data for 40 countries (and 35 industries) during 1995-2007 from the World Input Output Database (WIOD). The estimates for per capita CO2 emissions are truly comprehensive as these include all carbon emissions embodied in international trade and global commodity chains. Even if we find evidence suggesting a decoupling of production-based CO2 emissions and growth, consumption- based CO2 emissions are monotonically increasing with per capita GDP. We draw out the implications of these findings for climate policy and binding emission reduction obligations.
