The Source Reduction Summit

Built for the teams building SB 54 Source Reduction Plans

With California's Individual Source Reduction Plans now the central challenge for obligated producers, the Source Reduction Summit brings together the teams responsible for making SB 54 real — sustainability, legal, packaging, R&D, procurement, and supply chain — alongside their key suppliers and converters to move beyond abstract guidance and into practical implementation.

About the event

The Source Reduction Summit — Readiness Circle Live is a two-day, in-person working forum (June 2–4, 2026) for the teams developing SB 54 Individual Source Reduction Plans. This is not a traditional conference. It is a small-group, high-trust working session designed to help producers save time, avoid reinventing the wheel, and get direct access to the PRO and the top experts in the space. The program pairs curated Learning Exchanges with Expert Debriefs, supported by anonymous polling and Q&A to reveal where teams are actually getting stuck.

Join us June 2nd for an informal, welcoming meet-and-greet over drinks, followed by two days of programming at RTI International on June 3rd and 4th. Daily sessions will wrap by 5:00 p.m., leaving room for continued conversation and connection throughout the Summit.

Program focus

The summit is organized around two practical questions:

Day 1 (June 3): Short-Term Lens — Building Your Plan. Participants will work through what a compliant plan looks like, with a CAA briefing on expectations and guided breakouts across the five source reduction pathways: Reuse & Refill, Elimination, Material Substitution, Right-Sizing, and PCR Increase.

Day 2 (June 4): Long-Term Lens — Implementing Your Plan. The second day turns to what a ready, implementable plan looks like in practice — with RTI's policy foresighting methodology, pathway scenario deep-dives, and supplier and producer debriefs on feasibility, timelines, and internal readiness.

Sessions run under Chatham House Rule with external antitrust counsel in the room throughout. The Summit is a forum for implementation learning, not commercial strategy.

Pricing is designed to make it easy for teams to attend together. Circle member organizations receive two complimentary tickets, with additional member seats available at $1,250 per person. Non-member tickets are $3,000 per person. Participants are responsible for their own travel and lodging, and registration is first-come, first-served until capacity is reached.

Why now

The timing is deliberate. Following the May 31 CAA reporting deadline, obligated producers are entering the next phase of SB 54 implementation: developing Individual Source Reduction Plans that actually work for their portfolios. Teams are now facing the real portfolio, sourcing, and redesign questions that only become clear when plans meet packaging reality. Convening at this moment creates a rare window for candid, expert-led discussion on what "ready" really means.

Why this matters

Across the market, producer teams are interpreting the same five pathways separately — often without direct visibility into what their suppliers and converters can actually deliver. The Source Reduction Summit is designed to compress months of fragmented touchpoints into two days of concentrated, cross-functional learning, with suppliers learning alongside their customers under consistent confidentiality and antitrust safeguards.

Why RTI

Hosted at RTI International in Research Triangle Park, the summit pairs Circle’s neutral peer-learning structure with RTI’s independent research and modeling capabilities. RTI’s role helps ground the program in evidence-based analysis, particularly as producers prepare for California’s source reduction requirements and the packaging decisions that may affect future fee exposure and compliance risk.
