This study examines the relationship between environmental quality and life expectancy by reviewing the literature and conducting an empirical analysis of a panel of 166 countries over the period 2000–2022. Within the health production function framework, the analysis jointly considers CO₂ emissions, economic development, health expenditure, and institutional quality. The results reveal a nonlinear relationship between emissions and life expectancy: at low levels of pollution, emissions are associated with improved living conditions, while beyond a certain threshold, their negative health effects prevail. Moreover, economic development moderates this relationship, reducing and eventually reversing the positive impact of emissions in more advanced economies. These findings suggest that the environment–health nexus is strongly context-dependent and call for differentiated policy approaches.
Questo studio esamina la relazione tra la qualità ambientale e l’aspettativa di vita attraverso una rassegna della letteratura e un’analisi empirica basata su un campione di 166 paesi nel periodo 2000–2022. Inserendosi nel quadro della funzione di produzione della salute, l’analisi considera congiuntamente le emissioni di CO₂, lo sviluppo economico, la spesa sanitaria e la qualità istituzionale. I risultati evidenziano una relazione non lineare tra emissioni e aspettativa di vita: a bassi livelli di inquinamento le emissioni risultano associate a condizioni di vita migliori, mentre oltre una soglia prevalgono gli effetti negativi sulla salute. Inoltre, il livello di sviluppo economico modera tale relazione, riducendo e invertendo l’effetto positivo delle emissioni nei paesi più avanzati. I risultati suggeriscono che il nesso tra ambiente e salute è fortemente dipendente dal contesto e richiede approcci di policy differenziati.

Abstract
This study examines the relationship between environmental quality and life expectancy by reviewing the literature and conducting an empirical analysis of a panel of 166 countries over the period 2000–2022. Within the health production function framework, the analysis jointly considers CO₂ emissions, economic development, health expenditure, and institutional quality. The results reveal a nonlinear relationship between emissions and life expectancy: at low levels of pollution, emissions are associated with improved living conditions, while beyond a certain threshold, their negative health effects prevail. Moreover, economic development moderates this relationship, reducing and eventually reversing the positive impact of emissions in more advanced economies. These findings suggest that the environment–health nexus is strongly context-dependent and call for differentiated policy approaches.| File | Dimensione | Formato | |
