To find out which countries have fostered the greenest habits, we looked at various factors, including the percentage of renewable energy consumption, rail transport of passengers, EV sales, percentage of solar power consumption, target percentage of emissions reduction and Environmental Policy Stringency (EPS) Index. 

To calculate the overall green score of each country, we looked at over 30 countries. For the countries missing at least one or two factors, we put a 0 for their missing factors. We then used a weighted ranking system to calculate an overall average, which was then ranked to determine the country with the highest green score. 

Using a Net Zero Tracker, we collected data on each country's Net Zero goals. By looking at the 2023 scorecard, we ranked each country based on their target percentage of emissions reduction. Please note that we only looked at countries with available data for most of the other factors, so this list is not ranked on every country’s sustainability goals. 

The EPS Index was taken from OECD. This measures the stringency of environmental policy across different countries. To source data for more countries, we used CEIC data. The index is based on the degree of stringency of 13 environmental policy instruments, from climate to air pollution. The index also ranges from 0 (not stringent) to 6 (highest degree of stringency) and covers 40 countries. We used the most recent data, which was from 2020.

We sourced data from BP’s Statistical Review of World Energy to determine which countries have the highest renewable energy consumption. Using figures of each country’s renewable consumption in exajoules (input-equivalent, p.43), we calculated this as a percentage of each country’s primary energy consumption (p.8)  in 2021 to determine how much of the consumed energy is renewable. This was also done for hydroelectricity (p.42) and nuclear energy (p.41). 

We sourced data on the countries with the most solar energy by calculating the solar capacity (p.45) compared to its total electricity generation (p.50) to get the percentage of the total energy consumption from solar energy. 

To find out which nations saw the most increase in EV Sales year-on-year (2021-2022), we used historical data from a Global EV Data Explorer. The figures used were filtered by Battery Electric Vehicles (BEVs). We only took into account countries; e.g. data for ‘Other Europe’ and ‘Rest of the world’ were not considered due to being too broad. 

Using Eurostat, we gathered data on the rail transport of passengers in each country. We used figures from the World Bank to source data for non-European countries. This was measured based on the passenger kilometres in millions. These figures were then ranked in order using the most recent data available for each country. 

Data collection for all the above sections was completed on 04/09/2023.
