Episode Summary
Executive Summary: Dr. Steve Davis explains his path from lawyer to geologist to climate scientist to Watershed’s head of climate science, and how the startup helps large companies measure, report, and reduce emissions. The conversation covers carbon accounting basics, Scope 1-3 challenges, regulatory drivers, the role of science in corporate decarbonization, and how startups and scientists can work together to accelerate real-world climate action.
Main Topics: Steve Davis’s winding career path (Priority: 5/5): Davis describes moving from law and startup finance into geology, then climate science, academia, and finally Watershed, motivated by a desire to work on more policy- and decision-relevant problems. What Watershed does and why it matters (Priority: 5/5): Watershed helps companies calculate carbon footprints, produce audit-ready disclosures, and, most importantly, identify and implement emissions reductions across their operations and supply chains. Carbon accounting and Scope 1, 2, 3 (Priority: 5/5): The discussion breaks down the three emissions scopes and why Scope 3 is the hardest to measure because it depends on supply-chain data, modeling, and cross-company coordination. Science-driven decarbonization priorities (Priority: 5/5): Davis argues that companies are already bought into climate action and now need help choosing the highest-impact, lowest-cost reduction levers, with clean power, electrification, and logistics leading the list. Policy, reporting standards, and compliance pressure (Priority: 4/5): The episode explains how voluntary disclosure frameworks are increasingly being replaced by mandatory reporting regimes in the UK, EU, and potentially the US, making carbon accounting table stakes. Offsets, removals, and the 90/10 rule (Priority: 4/5): Davis emphasizes that emissions reductions should come first, with removals playing a smaller role; he also discusses Watershed’s vetting of nature-based removals and its relationship to Frontier for durable carbon removal. Bridging academia and climate tech (Priority: 4/5): He reflects on how scientific research can translate into corporate action, what startups should look for in a first climate scientist, and what scientists should expect when moving into a fast-paced startup environment.
Key Arguments: Davis entered Watershed because academic research alone felt too disconnected from the decisions actually being made in business; he wanted to influence real decarbonization choices. Carbon accounting is no longer just a reporting exercise; it is becoming a practical tool for deciding where to invest to reduce emissions most effectively. Scope 3 is fundamentally a data problem and often requires supplier engagement, modeling, and data-sharing across companies. Most companies’ largest emissions opportunities are the same broad levers society needs: clean electricity, building electrification, and transportation electrification. Existing infrastructure already locks in enough emissions that meeting 1.5°C requires premature retirement of some assets. Net zero pathways should rely mostly on reductions, not removals; removals are important but secondary and should not substitute for cheaper decarbonization measures. Companies are increasingly motivated not just by compliance, but by cost savings, customer expectations, employee expectations, and strategic advantage. The climate science community should play a larger role in climate tech, because technical business decisions benefit from scientific rigor and cross-disciplinary expertise.
Data Points: Watershed valuation: $1 billion - The company announced a Series B financing at this valuation. Series B financing: $70 million - Watershed’s announced funding round. Watershed customer count: close to 300 - Davis describes the range of customers using Watershed’s platform. Academic tenure: 10 years - He spent about a decade as a professor at UC Irvine before moving to Watershed. Climate target threshold: 1.5 degrees of warming - Davis says existing infrastructure alone would push the world beyond this target if it runs its expected life. Removals share of net zero: about 10% - He cites the science-based targets framing that net zero should be achieved roughly 90% through reductions and 10% through permanent removals. Reduction share of net zero: about 90% - Same explanation of the reduction/removal balance for net zero pathways. IPCC-supported model scope: 198 countries - The global CETA model acquired through Vital Metrics includes data across 198 countries. US emissions coverage from key levers: 70% to 80% - He says clean power, buildings, and transportation can address most U.S. emissions. Cheese example: harder cheeses have higher carbon footprints than soft cheeses - Used in the Sweetgreen example to show menu-level emissions optimization. Climate reporting framework count: 27 acronyms referenced - The podcast notes the many standards Watershed helps customers report to, including SFDR, TCFD, CDP, SASB, and GRI. National Climate Assessment drafting process: 6 drafts - Davis says the National Climate Assessment undergoes multiple rounds of drafting and review.
Pivotal Quotes: "I wanted to be somewhat more relevant and useful to the decisions that are getting made in our society." — Steve Davis: He explains why he moved from geology research toward climate-focused work and later into climate tech. "I think measuring your carbon footprint is really just table stakes here." — Steve Davis: He argues that companies must move beyond measurement into strategic emissions reduction and action. "There's a real return on investment that's going to come from pursuing this in an ambitious way and not just being a measurer and sitting by the sidelines." — Steve Davis: He describes the business case for proactive climate action beyond compliance.
Implications: Carbon accounting is becoming a core business function, not a niche sustainability exercise. Companies will need better data, science-based prioritization, and credible reduction plans, while climate scientists who can translate research into operational decisions will be increasingly valuable.
