The report details how this further increases the weighting of such charges within the overall basket of government revenues that stands at 6.5% of the total and would account for 8.9% in 2014 but for the removal of tobacco duty from this category in the meanwhile.


This weighting ranks Portugal slightly above the European Union average, 6.4% against the EU’s 6.3% even while the country remains below the average when measured in terms of GDP, 2.2% against 2.5%, according to the most recent figures from 2013.


These environment taxes include levies on transport, including road and vehicle tax, and on energy, both on fuels and electricity.


The National Institute of Statistics also calculated that households chip in with around half of the €3.87 billion raised last year and paying 51.4% of the energy levy and 51.8% of the extra transport taxation.


Meanwhile, REN, the national grid operator, reported Friday that September had seen the second month in a row of falling electricity consumption.


August had seen the rising trend in electricity consumption bucked with an annualised 0.4% fall that yawned to 1.6% in September when correcting for the effects of both temperature and working days.


Nevertheless, the third quarter saw Portuguese electricity consumption still manage to remain positive with a 0.1% year-on-year rise.
