The Donella Meadows Institute has been at the forefront of sustainability thinking and training.
Their mission is to shift mindsets — values, attitudes, and beliefs — when they are out of step with the realities of a finite planet and a globally powerful human race.
The Institute also works on restructuring systems when the rewards and incentives of the system are inconsistent with long term social, environmental, and economic goals. They also build the capabilities to manage and learn in complex environmental, social, and economic systems.
