This work explores the potential of adopting an alternative, sustainable approach to addressing climate change, as opposed to traditional policies that often prioritize economic growth and a market-based approach. The proposed alternative is sustainable economic degrowth, understood as a voluntary and gradual reduction in per capita consumption and hours worked, accompanied by environmental regeneration policies. In the first chapter, Natural Language Processing (NLP) techniques are used to analyse the evolution of the academic debate on environmental issues, with a particular focus on the concept of degrowth. The second chapter employs a Quantile Vector Autoregressive (QVAR) model to estimate the spillover effects between reductions in hours worked and consumption, income inequality, Ecological Footprint, and Carbon Footprint, with a particular focus on extreme quantiles. This approach aims to understand the response of economic systems in scenarios of environmental stress. The third chapter proposes an entropy indicator as a proxy for climate uncertainty, assessing the impact of demographic, economic, and productive factors on this uncertainty through a Stochastic Impact by Regression on Population, Affluence, and Technology (STIRPAT) model. Overall, the thesis aims to provide an integrated assessment of the environmental and social impacts of such a radical paradigm shift, offering valuable insights for policymakers who wish to design strategies that can reduce environmental damage without compromising the socio-economic well-being of populations.
Questo lavoro esplora le potenzialità dell'adozione di un approccio alternativo e sostenibile per affrontare il cambiamento climatico, rispetto alle politiche tradizionali che spesso privilegiano la crescita economica e approcci basati sul mercato. L'alternativa proposta è la decrescita economica sostenibile, intesa come una riduzione volontaria e graduale dei consumi pro capite e delle ore lavorate, accompagnata da politiche di riqualificazione ambientale. Nel primo capitolo vengono utilizzate tecniche di elaborazione del linguaggio naturale (Natural Language Processing, NLP), per analizzare l'evoluzione del dibattito accademico sulle questioni ambientali, con particolare attenzione al concetto di decrescita. Il secondo capitolo adotta un modello Quantile Vettoriale Autoregressivo (QVAR) per stimare gli effetti di contagio tra la riduzione delle ore lavorate e dei consumi, disuguaglianze di reddito, l'Impronta Ecologica e l'Impronta Carbonica, con focus sui quantili estremi delle distribuzioni. L'approccio permette di comprendere la risposta dei sistemi economici in scenari di stress ambientale. Il terzo capitolo propone un indicatore di entropia come proxy per quantificare l'incertezza climatica, valutando l'impatto dei fattori demografici, economici e produttivi su tale incertezza attraverso un modello di regressione su popolazione, ricchezza e tecnologia (Stochastic Impacts by Regression on Population, Affluence, and Technology, STIRPAT). Complessivamente, la tesi offre una valutazione integrata degli impatti ambientali e sociali di un cambio di paradigma così radicale, fornendo spunti preziosi per i decisori politici per progettare strategie in grado di ridurre il danno ambientale senza compromettere il benessere socio-economico delle popolazioni.

Abstract
This work explores the potential of adopting an alternative, sustainable approach to addressing climate change, as opposed to traditional policies that often prioritize economic growth and a market-based approach. The proposed alternative is sustainable economic degrowth, understood as a voluntary and gradual reduction in per capita consumption and hours worked, accompanied by environmental regeneration policies. In the first chapter, Natural Language Processing (NLP) techniques are used to analyse the evolution of the academic debate on environmental issues, with a particular focus on the concept of degrowth. The second chapter employs a Quantile Vector Autoregressive (QVAR) model to estimate the spillover effects between reductions in hours worked and consumption, income inequality, Ecological Footprint, and Carbon Footprint, with a particular focus on extreme quantiles. This approach aims to understand the response of economic systems in scenarios of environmental stress. The third chapter proposes an entropy indicator as a proxy for climate uncertainty, assessing the impact of demographic, economic, and productive factors on this uncertainty through a Stochastic Impact by Regression on Population, Affluence, and Technology (STIRPAT) model. Overall, the thesis aims to provide an integrated assessment of the environmental and social impacts of such a radical paradigm shift, offering valuable insights for policymakers who wish to design strategies that can reduce environmental damage without compromising the socio-economic well-being of populations.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
