Aim for this test is to start discussion regarding website impact on climate and environment. It is not perfect but hopefully a start.
We are giving websites a relative rating depending on the impact they would have IF they had the same visitor count and technical solution. We are doing this by taking the weight of the url in KiB and calculating a value from this. We then compare that value with a reference values and gives you a rating. The reference values represents the percentile for all urls checked by Webperf.se. This is updated manually and you can see when it was done latet by looking at the date in top of /tests/energy_efficiency_carbon_percentiles.py).
If you know any other way we could automatically compare impact on climate and environment a certain url has, PLEASE let us know :)
