NimbleFins, a personal finance website that conducts research and analysis on a variety of topics, has looked further into which EU countries are the greenest by analysing environmental data from the European Environmental Agency, Eurostat and the WHO (World Health Organisation).


With consistent showing across the board, Portugal ranks in the top half of every category with particular strength in energy and air quality categories.


Portugal gets 30 percent of its energy from renewable sources, which beats the study average of 25 percent, while also using a low amount of non-renewable energy (1.7 tonnes of oil per capita) compared to the study average of 2.8 tonnes.


The air quality is measured by the concentration of PM2.5 (air pollution particles less than 2.5 micrometres in diameter) per cubic metre. Sweden, Iceland and Finland tied for first place in this category with a value of 5.9 micrograms of PM2.5 per cubic metre, while Portugal found itself in sixth place with a value of 7.9 micrograms per cubic metre, still with a better value than the study average of 12.3.
