There might be a stronger connection between those who traditionally follow Judaism and those that are strict environmentalist. Here are just a few observations (below).
(1) Those who are traditional drive the maximum of 6 days a week in observation of Shabbos and other holidays. Walking is there means of travel much more then most.
(2) Traditional Jews don’t eat Milk and Meat together so there carbon footprint is lower at many a dinner table.
(3) These individuals tend to have larger families so that owning an extra carbon burning summer house is not possible.
(4) Tu BiShvat is a Jewish holiday that celebrates the environment and was formulated way before this modern green movement.
