The European Commission’s latest taxation trends report shows tax revenues from environmental and energy taxes were stable in the EU over the last decade while CO2 emissions decreased. However environmental taxes did fall slightly in 2017 to less than 2.5 percent of GDP.

Energy taxes, the main component of environmental taxes, comprised less than 2 percent of GDP in terms of tax revenues in that year. Other tax revenues in the EU as a percentage of GDP have continued their upward trend since 2009.

The report, published annually, also contains data on consumption, labour, capital and property taxation, plus rates for personal and corporate income taxes in each EU Member State.

It contains a detailed statistical and economic analysis of the tax systems of the 28 Member States of the EU, plus Iceland and Norway which are members of the European Economic Area.

In addition to the analysis of Europe-wide trends in Part 1, the report includes in Part 2 country chapters. For each country, key taxation indicators are provided on tax revenues as a percentage of GDP for the years 2005–2017.
