G20 Report

In the G20 report, below, the Environmental Rating Agency has adapted the AAA ratings traditionally used to assess the credit worthiness of countries to rank the G20 nations according to their relative environmental performance.

The goal of this report is to compare how well the G20 nations are protecting their, and our, environment and economy from avoidable risks and harm.

In addition to identifying areas of concern, we highlight where countries are succeeding, and have opportunities to enhance their resilience or competitiveness, through the assessment and incorporation of environmental risks, science and data into their long-term economic decision making.

No-one is getting everything right, and everyone has something to learn, share and do.

Please download the full G20 report for more details and see below for a brief summary of the report’s contents.

Ratings Scale

For each of the 12 environmental indicators included in this report, the country with the best environmental performance has been awarded an AAA-rating. The performance of the other countries has then been downgraded one rating for every 5% drop in performance, with the worst receiving a DDD rating.

Using our ratings scale there are 20 grades from the top AAA rating, down to the bottom DDD rating.

G20 “League Table”

In order to produce the G20 “league table” featured in this report the mean environmental rating of each country, across 12 environmental indicators, has been calculated, and ranked, in comparison to its G20 peers.


For the 19 member countries that make up the G20, national AAA – DDD environmental ratings have been determined for each of the following 12 environmental indicators: economic efficiency, energy efficiency, infrastructure investment, atmospheric emissions, environmental protection, land management, water resource use, corruption, social development, threats to endemic mammals, birds and amphibians, marine protected areas and air particulates (see Appendix 1).

National “Report Cards”

The national results for each indicator have been combined to produce national “report cards”. These “report cards” make clear the relative strengths and weaknesses of each individual country, and highlight the variation in environmental performance found within nations (see Appendix 2).

We are focused on helping experts, and non-experts, to understand key environmental data and to make more informed choices.
