Sustainability merit badge was introduced at the 2013
National Jamboree in July, and is now an alternative to Environmental Science as an Eagle-Required badge.
As of January 1, 2014, Cooking will become a required Merit Badge, bringing the total number of Eagle-Required Merit Badges to 13


Sustainability is more of a new way of thinking as opposed to the science in the Environmental Science merit badge,” says Scott Berger of Scotch Plains, N.J., chairman of the Sustainability Leadership Team overseeing the merit badge’s development and chairman of the Merit Badge Maintenance Task Force. “The idea is not just to conserve but to truly be stewards of our environment, our energy sources, and more—to think in terms not just of having enough for our lifetime but enough for future generations."
 "It’s a hard concept for a Scout to feel that he himself, as a single person, can have an impact on the world, but he certainly can have an impact within his own family," Berger says. "We’re hoping to bring [sustainability] down to a level where a Scout can feel he can make a difference, where his actions matter.”
There are two major revisions to Cooking merit badge - that should be considered separately. The first is that Cooking merit badge will become Eagle-required beginning January 1, 2014. The second is a major overhaul to the requirements, which will take effect January 1, 2015.
Beginning January 1, 2014. Regardless of when a Scout earned the Life rank or began working on Eagle, unless he fulfills all the requirements — with the exception of his board of review — before January 1, 2014, he must earn the Cooking merit badge to become an Eagle Scout.
