I don’t know exactly when “green” became the de facto official color of environmentalism, but it dates back at least to the 1970s, when European political parties rooted in ardent environmental positions took the name “Green”.
But, as Paul Markille noted in The Economist‘s excellent annual round-up of speculations for the new year — “The World in 2012” — there seems to be a movement afoot to brand environmentally-friendly things with the color blue rather than green.
Green is about trees and plants, whereas blue is about oceans, rivers, lakes and the sky. As environmentalism and cleantech increasingly move from protecting pristine wilderness areas towards ensuring adequate clean supplies of essential resources — air and water — perhaps a color change is warranted.
For sure, blue is more acceptable to right-of-center political interests than the term green has become since being appropriated by left-of-center parties in Europe. Something for cleantechers to think about…
It does bring new meaning to the University of Michigan rally cry, “Go Blue!”
