Erin Williamson

Senior Manager, Energy & Sustainability Strategy

I work with clients to support their sustainability needs, from greenhouse gas management to strategic planning to goal setting and beyond.

Prior to joining Edison, I worked in the corporate environmental sustainability office at Northrop Grumman, a Fortune 100 global security company. I handled everything carbon-related and therefore have a client’s perspective on navigating the challenges of implementing ambitious decarbonization initiatives. I also led a GHG work group for the International Aerospace Environmental Group, where we were focused on developing industry supplemental guidance on reporting, and I’m proud to have led a huge effort to build a Scope 3 reporting tool and guidance tailored to the complex supply chain of the aerospace and defense industry.
