Pollution Haven or Halo? How European countries leverage FDI, energy, and human capital to alleviate their ecological footprint

The nexus between economic growth and the ecological footprint has been a recurring focus investiga-tion for a long time. European countries are speeding up their environmental efforts to improve air qual-ity, and their commitments for implementing the Paris Climate Agreement's 2015 treaty action plans. Thus, this paper investigates the environmental Kuznets Curve and the pollutant halo hypothesis for the time period of 1990-2020 for 16 European countries. The empirical analysis uses cross-sectionally augmented autoregressive distributed lag modelling, which accounts for time dynamics, cross-sectional dependence, and cross-sectional heterogeneity. The Augmented Mean Group and Dumitrescu and Hurlin panel causality tests were also employed in this study. The empirical result revealed valida-tion of the pollution Halo Hypothesis, foreign direct investment and ecological footprints have a negative correlation. GDP and its square form an inverted U-shaped curve, which supports the environmental Kuznets Curve hypothesis. When it came to ecological footprints, renewable energy had a negative cor-relation, whereas energy structure had a positive one. Nonetheless, GDP and ecological footprints have a bidirectional causal relationship. Furthermore, the panel non-causality test revealed a bidirectional causality relationship between ecological footprints and GDP, but a unidirectional causality relationship is discovered from foreign direct investment, renewable energy, energy structure and human capital with ecological footprint. According to the findings of the research, a number of policy recommendations for the analysed bloc are provided, including the implementation of resource conservation as well as the establishment of sustainable energy policies.(c) 2023 International Association for Gondwana Research.

Automated summary

This study investigates the relationship between economic growth and ecological footprint for 16 European countries from 1990 to 2020. The empirical analysis reveals some correlations, including a negative correlation between foreign direct investment and ecological footprint, and an inverted U-shaped curve between GDP and ecological footprint, supporting the environmental Kuznets Curve hypothesis. Furthermore, renewable energy is found to have a negative correlation with ecological footprint, while energy structure has a positive correlation.
