| Summary: | Global warming, which is a consequence of the rapid increase of CO2 emissions, has attracted the world’s attention. Usually, the growth of economy occurs in parallel with the increase in energy demand, which in turn would lead to the high levels of GHG emissions. Decoupling provides reduction of environmental pressure without deterioration of economic growth of a country. In this study, decoupling relationship between GDP and CO2 emissions from public electricity and heat generation sector was investigated for EU-15 for the period from 1990 to 2014. The decoupling assessment was performed by using two methods: the Tapio decoupling elasticity method and OECD decoupling factor method. Based on results of both of those methods the decoupling states were defined. The results demonstrate that the decoupling states between GDP and CO2 emission intensity (CO2 emissions from public energy and heat production sector) fluctuated to a significant extent during the entire study period 1990-2014 for EU-15. Thus, no clear patterns for decoupling states were observed. Nevertheless, almost in all countries strong and weak decoupling were mostly occurred between GDP and CO2 emission intensity. In comparisons, the Tapio results represented more comprehensive picture of decoupling relationship between chosen indicators compared to the OECD method. Under the Kyoto Protocol, EU-15 countries were committed to reduce their GHGs emissions to 8% below the 1990 levels between 2008 and 2012. According to EEA, total EU- 28+Iceland emissions were below 1990 levels in 2014. It has been found that Austria, Denmark, Luxembourg and Spain produced significantly higher levels of emissions than their initial targets committed under the first commitment period 2008–2012 of Kyoto Protocol respect to 1990 levels. However, this tend to be not correlate with decoupling performance of countries in a specific sector. Among all countries of EU-15, only in Luxemburg the GDP strongly decoupled from CO2 emissions from public energy and heat production sector ...
