A decomposition and decoupling analysis for carbon dioxide emissions: evidence from OECD countries

Abstract Despite the huge difference in their climatic regimes, OECD countries are among world’s largest energy consumers and emitters of greenhouse gases, particularly carbon dioxide. Nonetheless, no studies have been conducted to decompose decouple long-term influential primary factors emissions for these countries. In this research, Log Mean Divisia Method I is used inspect contribution several influencing fill knowledge gap. Moreover, Tapio (Transp Policy 12(2):137–151, 2005) decomposition analysis (DA) performed investigate driving forces CO 2 over 1990–2019 years. The study provides an in-depth how reduce that contribute variation, which crucial both global regional climate change policies. DA shows that, up 2004, activity effect population drove increase; while, more recent years, was able curb emissions. Decoupling show prevalence expansive negative decoupling regime 1990–2004 2015–2019 periods, while were strong phase central period (2005–2009). According results, further efforts increase efficiency, political support digitalization decentralized systems, setting a unique emission trading system recommended air pollution reduction.
