The awareness of the Earth’s slow decline has led many organizations to integrate ESG (Environmental, Social and Corporate Governance) strategies within their mission, purpose, and cultural DNA. Today’s achievement is to be able to debunk the myth that organizations must choose between doing financially well versus doing right in relation to the planet. However, the effort of just a handful of people is not enough to save our world, so sustainable leadership, or what we might call even more specifically green leadership, must aim to create broad-based partnerships. The new mindset requires the creation of an organizational culture based on sustainable behaviors and a long-term vision. In the 21st century, the contemporary leader is faced with a new challenge: to adopt, transmit and enhance sustainable behaviors that are compatible with the environment. In concrete terms, leaders will be called upon to be agile in actions and thinking, willing to rethink their business models to respond to the new reality, know how to take advantage of new opportunities, and succeed in turning risks into strategic advantages. The leader’s role becomes that of channeling people in to collaborative action, providing confidence, and direction, and managing the emotional dimension of the organizational ecosystem in relation to the green shift. Why invest in this transformation? Because The so-called “green shift” has come to stay! Policymakers, customers, and even people within organizations demand it.
