Aaron and Jaclyn work through the distinction between verification, assurance, and validation
Jaclyn Sherman’s path into carbon accounting started in the field, monitoring water quality on the Yuba River, tracking aquatic invasive species, and working on meadow restoration and carbon sequestration projects in the Sierra foothills. That hands-on background now shapes how she approaches one of the most technical corners of sustainability work: GHG inventory assurance.
Today Jaclyn is a Sustainability Analyst at Sensiba LLP, a top-100 U.S. accounting firm and the first California-based firm to earn B Corp certification. She leads GHG assurance engagements for food and beverage clients and has built her expertise through a combination of the GHGMI diploma program, deep on-the-job learning, and the kind of stay-curious adaptability that this rapidly evolving field demands.
In this episode, Aaron and Jaclyn work through the distinction between verification, assurance, and validation; what data quality frameworks actually look like in an assurance engagement; and how readiness assessments help companies scope out where they stand before committing to a full inventory. They also build out a practical 90-day roadmap for a mid-sized food and beverage company trying to tackle Scope 3 Category 1 purchased goods, where 70% of purchases are agricultural commodities starting from scratch.
The conversation also covers inventory management plans and the practical steps practitioners can take to future-proof their inventories through methodology changes, staff turnover, and evolving emission factors. And Jaclyn shares a candid take on how AI is showing up in GHG accounting work and what that means for assurance providers trying to evaluate data they can’t fully trace.
