Pledge of the Hawk

We endeavor to overcome the tension between efficiency, profitability and dynamism on the one-hand and solidarity, equity and sustainability on the other.

We pledge to select Portfolio, Joint Venture, Teaming and Capital Partners dedicated to sustainable business, free market societies and interdependent business relationships.

We vow to make decisions with an eye toward success in the marketplace but also in view of minimizing impact on the environment, achieving team member satisfaction, and maximizing human and social usefulness.

Our principle aspiration is not just to increase value for the shareholders by exploiting all the available resources, but to assume social and ecological responsibility for the stakeholders.

Our intent is that business is no longer considered a separate “private” sector but rather that companies such as GreenHawk™ become a functional and integral part of the communities we serve.
