Bu çalışmada EUROCONTROL üyesi ülkelerin milli gelirleri ile havacılık sektörlerinin uçuş başına karbon dioksit salınımı arasındaki ilişki; 34 ülkenin Ocak 2010 – Eylül 2021 dönemi verileri kullanılarak analiz edilmiştir. Petrol fiyatları ve COVID 19 sürecini temsil eden kukla değişken ile veri seti genişletilmiştir. Model katsayıları DOLS yöntemiyle tahmin edilmiş, havacılık sektöründe uçuş başına düşen karbondioksit emisyonu ile milli gelir arasında Çevresel Kuznets Eğrisi Hipotezinin Belçika, Finlandiya, Almanya, Yunanistan, Macaristan ve Romanya’da geçerli olduğu belirlenmiştir. Bu ülkelerden Belçika, Yunanistan, Macaristan ve Romanya’da ters N şeklinde, Finlandiya ve Almanya ise N şeklinde kübik Çevresel Kuznets Eğrileri söz konusudur. Çizilen grafikler de söz konusu ekonometrik bulguları destekler niteliktedir.

The Validity of The Environmental Kuznets Curve Hypothesis in Eurocontrol as a Financial Union: An Econometric Analysis

Öz

In this study, the relation between the national income and the carbon-dioxide emission per flight of the aviation sector of 34 member countries of EUROCONTROL is analyzed for January 2010 - September 2021 period. The data set is expanded with oil prices and a dummy variable, representing COVID-19 period. The model coefficients are estimated by DOLS method and it is determined that Environmental Kuznets Curve Hypothesis is valid between carbon-dioxide emission per flight in the aviation sector and national income for Belgium, Finland, Germany, Greece, Hungary and Romania. Among these countries Belgium, Greece, Hungary and Romania have inverse N shaped and Finland and Germany have N shaped cubic Environmental Kuznets Curve. Also, the drawn figures are supporting the related econometric findings.
