Green Complexity, Economic Fitness, and Environmental Degradation: Evidence from U.S. State-Level Data
Abstract Green production is one of the major debates as environmental degradation poses threats globally. The paper attempts to explore the relationship between green economy and environmental quality by using Economic Fitness approach. We develop a Green Complexity Index (GCI) dataset consists of 290 traded green-labeled products for the US States between 2002 and 2018. We analyze the environmental performance of green production using the GCI data at the sub-national level. Findings indicate that exporting more complex green products has insignificant effects on local (i.e., Sulfur dioxide, Particulate Matter 10) and global polluters such as Carbon dioxide (CO2), even accounting for per capita income. Yet, overall economic complexity has a significant negative impact on the emission levels implying that sophisticated production significantly improves environmental quality in the US. The insignificant impact of GCI on environmental degradation suggests that green product classifications should incorporate the production and end-use stages of goods to limit the adverse environmental effects of green-labeled products. The study, therefore, provides policy implications for green industrial policies.JEL codes: O18, Q56, R11
