Developing an Individual Source Reduction (ISR) Plan under California's SB 54 is more than a compliance exercise - it's a strategic planning process.

As producers work toward California's requirement to reduce covered plastic packaging by 25% from a 2023 baseline by 2032, organizations must evaluate multiple source reduction pathways, prioritize opportunities, document their decision-making, and develop a plan that can withstand regulatory scrutiny as implementation guidance continues to evolve.

In this webinar, PCX Markets explores the practical side of California source reduction compliance, including recent Circular Action Alliance (CAA) guidance, common implementation challenges, and the questions we're hearing most often from producers as they develop their ISR Plans.Rather than focusing solely on what the regulatory requirements are, this session examines how companies are translating those requirements into practical, defensible source reduction strategies.

In this webinar, you'll learn:

• How to build a defensible Individual Source Reduction (ISR) Plan under California SB 54

• Recent CAA guidance and implementation considerations

• How to evaluate and prioritize different source reduction pathways

• Packaging data, baseline development, and documentation best practices

• How producers are modeling and evaluating different compliance scenarios

• Practical considerations when evaluating packaging redesign, material substitution, elimination, reuse, and lightweighting opportunities

• Common challenges organizations encounter when developing source reduction plans

• How to document assumptions and decision-making to support a credible compliance strategy

• Frequently asked questions from producers preparing for California's source reduction requirements

Who Should Watch

This webinar is designed for sustainability leaders, packaging engineers, product development teams, regulatory affairs professionals, legal and compliance teams, operations leaders, and anyone responsible for California packaging compliance or packaging Extended Producer Responsibility (EPR).

Whether you're validating an existing ISR Plan or looking for practical guidance on selecting and documenting your source reduction strategy, this session provides actionable insights to help your organization prepare for California's evolving packaging regulations.
