Human activities in recent decades have severely affected environmental quality, and
CO2 emissions have irreparable consequences on human health and the survival of the
earth. Moreover, achieving sustainable development goals requires the expansion of
environmental literature to accelerate the performing of critical actions. With this
in mind, this study evaluates the impact of foreign direct investment, economic complexity,
and the utilization of renewable energy on CO2 emission in N-11 countries from 1995
to 2019 by Panel Quantile Regression. As a novelty, the interaction between economic
complexity and foreign direct investment is considered to get a better comprehension.
Given the results, Environmental Kuznetz Curve is validated in N-11 countries through
economic complexity. Notably, the impact of economic complexity is more substantial
and robust in the incipient stages of industrialization. Furthermore, foreign direct
investment is a destructive factor for environmental quality, and Pollution Haven
Hypothesis is not rejected. Interestingly, the interaction of economic complexity
and foreign direct investment mitigates the trend of CO2 emissions. Eventually, the
utilization of renewable energy reduces CO2 emissions. Thereby, applying more strict
environmental regulations and standards, developing green energy infrastructure and
technologies, improving institutional quality, and supporting knowledge-based and
technology-intensive exports are the main policy recommendations of this study.
