About ea

We are not just a consultancy, research organization, or driver of system change. We encompass all of these and more, united by a broad commitment to drive transformative change.

We are Superspreaders (of impact)

From the beginning EA was envisioned as a place where the world’s current path towards exceeding planetary boundaries could be addressed at multiple levels.

The first level, like the roots of a dandelion, is robust research, providing the foundation that supports all other efforts. EA services, solutions and expertise can be understood as the stem, with direct support being provided to foster the growth and success of clients and partner organizations. With these anchors in place, EA is positioned to directly and indirectly disseminate research-based and practical initiatives and action to create a ripple effect of positive impact and necessary change.

EA’s commitment to broader change is also firmly established in the organization’s design where all profits generated in the for-profit side, EA Sàrl, are reinvested in the non-profit arm, the EA Association, to support scientific advancements, global partnerships and the design of research-based solutions to expand environmental responsibility and reign in humanity’s impact on the planet.

News & Press
