Factors affecting Germany’s green development over 1990–2015: a comprehensive environmental analysis

Abstract

This study was aimed at providing a comprehensive environmental analysis of Germany from 1990 to 2015. First, an ecological footprint analysis of the country was conducted using bio-capacity and ecological footprint data. Second, possible decoupling of the country's economic growth and carbon dioxide (CO₂) emissions was examined using the decoupling factor adopted by the Organization for Economic Co-operation and Development (OECD). Third, the factors affecting aggregated and sector (electricity and heat production) emission changes were identified using the Logarithmic Mean Divisia Index (LMDI) method. The empirical findings revealed that Germany experienced a slowly decreasing ecological deficit over the entire period. The decoupling-factor calculations showed absolute decoupling of the country's real GDP and CO₂ emissions. Based on the LMDI calculations, per capita income and population had increasing impacts on aggregated emissions, whereas energy intensity and carbon intensity curbed them substantially. For electricity and heat production, economic activity was the only CO₂-accelerating factor observed in the study period. In addition, the fuel structure effect, pollution effect, and electricity intensity considerably reduced the emissions of electricity and heat production. It, therefore, is possible to conclude that Germany is an impressive example of environmental sustainability for other nations.
