Founder’s Vision
Evergreen International Sustainability Solutions (EISS) was founded on a simple but powerful belief: that solving our planet’s most complex challenges requires adaptive expertise, pragmatic innovation, and collaboration across boundaries.
We see sustainability as security. A system of relationships between people, place, and purpose. Our work bridges these relationships to turn ideas into outcomes: measurable environmental gains, durable financial models, and empowered leadership.
At Evergreen, our mission is to bring solutions to market. Solutions that are scalable, science-based, and rooted in the real-world conditions of the communities and ecosystems we serve. We operate with agility, integrity, and optimism. Because the world doesn’t need more plans; it needs people who can make them real.
