Abstract
Environmental issues are increasing due to the elevated level of greenhouse gas emission worldwide. The current study is an effort to explore the solutions to control environmental gasses, in European countries by using the past and predicted data from 2015 to 2030. Through empirical analysis by applying dynamic simulated ARDL, it is noted that hydrogen energy consumption is an optimal solution for these issues because it results in low greenhouse gasses emission. The findings of energy consumption are surprising, as a result of increased energy consumption, greenhouse gasses and domestic carbon emissions are reduced. It is also noted that domestic and international transport are the major contributors to environmental damage due to the high consumption of fossil fuels. KRLS estimations have affirmed the similar outcomes. It is advised that policymakers should invest in the production of green hydrogen to reduce environmental damage.
•We study the significant factors of greenhouse gasses, domestic CO2 and international CO2.•Domestic and international transport are key sources of environmental damages, in EU countries.•Hydrogen energy act as an optimal solution to minimize the GHG and carbon emission.•Economic growth is significant and positive for GHG and domestic CO2, while insignificant for international CO2.
