The article substantiates the necessity to introduce systematic and effective tax eco-reforms in the context of resource-oriented economic development by the European Union countries. The performance and effectiveness of the reforms are estimated in relation to the main four groups of environmental taxes: energy taxes, pollution taxes, resource taxes and transport taxes. The macroecological policy of the European Union countries is the object of the undertaken analysis. The article examines the impact of macroeconomic factors on environmental taxes across the EU, using a correlation analysis toolkit. Four groups of macroeconomic parameters were selected for analysis: internal macroeconomic factors (nominal GDP, real GDP, inflation, business cycle stage, budget deficit, energy consumption level); external macroeconomic factors (government debt, exports, foreign direct investments); institutional macroparameters (environmental culture, shadow economy, trust in government) and fiscal macroparameters (tax culture and fiscal freedom). The economic interpretation of the obtained correlates is given. Based on the correlation analysis, stimulators and de-stimulators of tax environmental reforms across the EU were identified. It is established that the factors that positively influence on the tax environmental reforms are the overwhelming majority of the analyzed factors. The formation of indicators of the effectiveness of tax environmental reforms is undertaken for six countries of the Community. In particular, the analysis covers three economic leaders (Germany, the United Kingdom and France) and three leading EU countries in the field of environmental tax collection (Latvia, Greece and Slovenia). The article presents approaches to improving the assessment of the effectiveness of tax environmental reforms based on the consideration of fiscal (budget-filling) and reproductive (multiplicative) functions of environmental taxes. In this regard, the environmental tax multiplier and accelerator, as well as the GDP elasticity coefficient for environmental taxes, were calculated for the analyzed group of countries. The criteria of economic efficiency of tax eco-reforms are proposed.
