What Sustainability Roundtable does

Sustainability Roundtable, Inc. (SR Inc) is a Boston-based, for-profit Public Benefit Corporation and certified B Corp founded in 2008 by James F. Boyle. The company is a strategic advisory and member-community firm that helps corporate sustainability leaders set ESG goals, design programs aligned with SASB, TCFD, GRI, CDP, CSRD, and the SEC Climate Rule, set Science-Based Targets under the SBTi Net Zero Standard, and execute Scope 1-3 decarbonization strategies. Its core offerings are the Sustainable Business & Enterprise Roundtable (SBER), a recurring membership providing advisory services, member-only research, a digital library, and quarterly Executive Symposia, and the Net Zero Consortium for Buyers (NZCB), a confidential transaction platform that aggregates corporate buyers to procure utility-scale renewable energy through competitive reverse auctions, a proprietary 5-level risk analysis framework, and multi-scenario financial modeling. NZCB's "VPPA 2.0" model has facilitated over 1.1 GW of new utility-scale renewable energy globally and over $1 billion in completed transaction volume across North America, Europe, and India.

SR Inc serves more than 100 Fortune 500 and global growth enterprises — including PTC, Cisco, Autodesk, Biogen, Synopsys, IDEXX, Cadence, Bloomberg, Intuit, Akamai, Teradyne, Waters, GoTo, and Wayfair — as well as municipal governments (notably the City of Cambridge). Revenue is generated through recurring SBER membership dues that bundle NZCB platform access, supplemented by transaction-facilitation services tied to aggregated VPPA closings. Distribution is invitation-only and enterprise field-sales driven, with member referrals from existing Fortune 500 logos as the primary acquisition channel; the firm operates from its Boston headquarters and convenes members at quarterly in-person and virtual symposia. The company has been bootstrapped since a $1.2M seed round from Navitas Capital in 2011, transitioned to Public Benefit Corporation status in December 2024, and achieved B Corp certification in April 2025.
