@Miniver one possible way to jam this trick is to turn it back on the polluters and look at their "footprint" - e.g. the 100 companies with 71% of the world's footprint: https://www.theguardian.com/sustainable-business/2017/jul/10/100-fossil-fuel-companies-investors-responsible-71-global-emissions-cdp-study-climate-change

Maybe it's possible to do that for littering too, but maybe it's harder, given how much more time the concept of a "litterbug" has been hanging around and defined as an individual person..
