Wine, Glass, and Scope 3: Inside Spottswoode Estate's Carbon Journey
Molly Sheppard is VP of Winery Strategies at Spottswoode Estate Vineyard & Winery in Napa Valley — a 37-acre, 20-person estate with one of the most rigorous sustainability programs in American wine. In her role, Molly oversees Spottswoode’s industry-leading environmental initiatives — including six years of IWCA-verified Scopes 1–3 greenhouse gas inventories.
In this episode, Molly takes us inside what carbon accounting looks like at a small but serious operation: how a first inventory can reveal a Scope 3 hotspot you can actually do something about, why "don't let perfect be the enemy of good" is the most important advice for practitioners struggling with Scope 3 data, and what it really takes to run a credible GHG program without a dedicated sustainability team.
Topics include:
- The glass lightweighting journey that took Spottswoode's estate Cabernet bottle from ~790g to 495g — driven directly by what the numbers revealed
- Managing the cultural challenge of lightweighting in a luxury wine market where bottle weight equals perceived quality
- Tools, timing, and practical strategies for running a Scope 3 inventory at a small business
- Engaging your supply chain: why Scope 3 is hard now and what the future could look like when "your Scope 3 is somebody's Scope 1"
- Regenerative organic farming, soil carbon sequestration, and what carbon neutrality could eventually mean for an estate like Spottswoode
- The business case for environmental leadership — from operational cost savings to next-generation consumer loyalty
