EARTHYS is a sustainability think tank that takes an evidenced-based approach to understanding sustainability problems, and formulating solutions that support a circular economy. Because behaviour shapes the success of environmental initiatives, we place importance on understanding the interplay between behaviour & sustainability, and how this can be utilised to solve challenges. We believe, the importance of natural resources, however small, need not be compromised or sidelined in the pursuit of growth.
