LONDON, England — The term “eco community” might conjure up an image of bearded hippies tending an allotment before sharing a mung bean stew. But as today’s urbanites become more concerned about reducing their carbon footprints, some are finding that modern eco communities offer them a way to live sustainably without foregoing their home comforts.

Communities that put an emphasis on green values range from isolated eco villages to sophisticated co-housing projects.

Co-housing was dreamed up in Denmark in the idealistic 60s. It allows residents to live in communities where they own their own homes but are actively involved in running their own neighborhoods, which often include a common house where shared dining and other activities are an option.

Sarah Berger, from the UK Co-housing Network, told CNN, “More and more people keep contacting us about getting involved in co-housing communities — there’s an unquenchable thirst for this sort of thing.”
