Sustainability & Environment Ranking Factors
To identify the best and worst countries for a sustainable life abroad, survey participants were asked to rate their personal satisfaction with the following factors on a scale of one to seven: air quality, the natural environment, water and sanitation, the availability of green goods and services, energy supply, and the local waste management and recycling infrastructure. The rating factors also include their perception of how strongly the government supports policies to protect the environment and how interested the local population is when it comes to environmental issues. For a country to be featured in the Environment & Sustainability Ranking, a sample size of at least 75 survey respondents per country was necessary. In 2020, 60 destinations met this requirement.
