First off, sustainability doesn’t necessarily stop at recycling old plastic bottles. 

The term applies to a wide range of guidelines that have been adopted to consciously minimize or eradicate pollution in the environment.

The countries that make this list are notable for waging war on toxic substances. 

They have made it a healthy choice to conserve water, energy and try to eradicate or minimize air, land, and water pollution.

The world’s most sustainable countries are located in Europe and graded according to EPI.

EPI, or Environmental Performance Index, is a ranking system used to classify countries based on their efforts to preserve the earth’s natural ecosystem. 

It acts as a means of measurement of these countries’ environmental policy success. 

This index is taken from the scores of each country’s performance indicator of the quality of life. Some of these indicators include sir quality, water quality, animal life preserve, etc (source)

Here are 10 of the most sustainable countries in the world, and why they are sustainable: 


Located in Northern Europe, Denmark is no doubt one of the greenest countries today. 

With an amazingly high Environmental Performance Index of 82.5, Denmark safely secured a spot as the most sustainable country in the world today. 

It is today one of the countries with outstanding scores in biodiversity and air quality. 

Denmark has established and sustained a very eco-friendly culture and established policies to teach its citizens to take more care of planet earth. 

These policies, for one, aim at effectively reducing the greenhouse effect and achieving a goal of fossil-free energy production.


Luxembourg is a mostly rural, and dense small European country bordered by Belgium, France, and Germany. 

This small country, however, ranks high as the second most sustainable country in the world. 

Boasting an EPI of 82.3, Luxembourg has managed to sustain high scores in biodiversity, habitat, and water resources.

It achieved this by setting policies for a smooth transition towards a carbon-neutral economy, better land use preservation, prevention of the loss of natural habitats, and aiming for better climate change.


Switzerland is a scenic, mountainous country located in Central Europe. 

With an Environmental Performance index of 81.5, Switzerland has managed to be termed the third most sustainable country in the world.

Switzerland has been strongly dedicated to maintaining and developing sustainability in the past few years.

Switzerland encourages the use of eco-friendly goods and services, aiming to make the country a better place one recycle at a time.

The United Kingdom

Coming up as number four, The U.K. has an EPI score of 81.3. 

The U.K. recognizes the need for a healthy, clean, and safe environment and achieves its sustainability goals on four broad objectives:

Unsurprisingly, the U.K. holds a perfect score of 100 for immaculate sanitation. It also has in place policies to push the gradual eradication of fossil fuel to reduce carbon footprint.


France has an Environmental Performance Index of 80, coming in fifth. 

It boasts of rather good scores on water sanitation and the absence of air pollutants. 

France ranks first for food sustainability, fourth in climate change, and fifth in biodiversity. 

It is worth noting that France has put in place initiatives on recycling clothing, throwing away food, installing hydro turbines for cleaner power, recycling used plastic, ridding the roads of old polluting cars, and has put in place policies to aid its “fossil-free” journey.


Located in the East Alpine country in the southern part of Central Europe, Austria has an EPI score of 79.6. 

Austria has explored various efforts to make sure its environment remains eco-friendly. 

It engages in organic farming and has employed strict air quality standards, monitors the quality of water, owns an impressive sewerage connection rate that reaches up to 85% of the family population, and pesticide regulation policies.


Finland has an Environmental Performance Index of 78.9. This is helped by its relatively low population density and mostly unspoiled natural environment.

Finland boasts of good air quality, having the cleanest air in EU countries, and stringent environmental regulations. 

It invests in and prioritizes renewable energy, protection of natural habitat, and better climate change.


Coming in close with an EPI score of 78.7, Sweden stands as the eighth-most sustainable country in the world. 

Sweden possesses the highest percentage of renewable energy in the world. 

Having cut down its use of fossil fuel, it strives to be the first fossil-fuel-free country by 2050.
