This is one of the environmentally-oriented rankings that many of us think about, from time to time, and then throw our hands in the air in frustration at the criteria used for judging green-ness, or what is often green-ish-ness. Thanks to the Guardian for asking the questions we want answered when it comes to rankings like this:
Where is the world’s greenest city?
Bristol is the ‘green capital’ of Europe, but its predecessor Copenhagen comes top in a Europe-wide index. Curitiba, San Francisco and Singapore all have strong eco-friendly claims too – so what’s the best way to compare cities’ greenness?
It’s easy to say we’d like our cities to be cleaner and greener. But what does that even mean? “Greenness” is a concept that’s hard to pin down – there’s no official list of the top 50 most eco-friendly cities, nor any widely agreed set of measurements for working out how green a city actually is.
