EPR Eco-Modulation: How Fee Structures Reward Sustainable Packaging
EPR fees are not flat taxes. Every U.S. packaging EPR law includes provisions for eco-modulation — adjusting producer fee rates based on the environmental performance of their packaging. In theory, eco-modulation transforms EPR from a simple cost-shifting mechanism into a market signal that rewards recyclable, recycled-content, and reusable packaging while penalizing materials that are difficult to process. In practice, the design of eco-modulation systems will determine whether EPR drives genuine packaging innovation or merely redistributes costs.
The Mechanics of Eco-Modulation
Eco-modulation works by applying bonuses (fee reductions) or maluses (fee surcharges) to the base rate a producer pays per unit or per ton of packaging placed on market. Holland & Knight's January 2026 analysis confirmed that U.S. EPR fee structures may include eco-modulation bonuses or maluses, though the specific rate schedules are determined by PRO program plans approved by state regulators rather than set directly by statute. The criteria for adjustment typically fall into several categories: material recyclability (is the packaging accepted by curbside recycling programs?), recycled content (what percentage of the material comes from post-consumer sources?), packaging format (is it readily sortable at materials recovery facilities?), and the presence of problematic components (labels, adhesives, or multi-material laminates that contaminate recycling streams).
How It Works in Oregon
Oregon's SB 582, the most mature operational EPR program in the country, provides the closest look at eco-modulation in practice. CAA's Oregon program plan, approved by the Department of Environmental Quality, establishes fee rates that vary by material type and recyclability classification. Packaging made from materials that are widely accepted by Oregon's recycling infrastructure — such as PET bottles, HDPE containers, corrugated cardboard, and glass — generally receives more favorable rates than packaging made from materials with limited recycling pathways, such as flexible plastic film, polystyrene, or multi-layer pouches. Oregon's three-category coverage structure (packaging, printing/writing paper, and food service ware) also means that different product categories carry different baseline rates, reflecting the varying costs of managing those materials at end of life.
California's Ambitious Targets and Eco-Modulation
California's SB 54 creates the strongest structural incentive for eco-modulation because of its aggressive statutory targets. The requirement that 100% of single-use packaging be recyclable or compostable by 2032, combined with a 25% plastic source reduction mandate, means that California's fee structure must create sufficiently strong price signals to drive material substitution and format redesign at scale. CalRecycle's rulemaking process — restarted by Governor Newsom on March 7, 2025 — will ultimately determine the specific eco-modulation framework, but the statutory targets set a floor for ambition. Producers whose packaging is already recyclable and uses high recycled content stand to benefit from lower fees relative to competitors still using difficult-to-recycle formats.
Colorado's Approach
Colorado's HB 22-1355 mirrors Oregon's model, and CAA's program plan for the state includes analogous eco-modulation provisions. With first fees due January 1, 2026 based on 2024 supply data, Colorado producers are now receiving their first direct experience with how packaging design choices translate into EPR cost differences. The initial fee period will establish baseline data on how eco-modulation affects producer costs and whether the price differentials are large enough to motivate packaging changes. Early indications from Oregon suggest that the fee differential between easily recyclable and hard-to-recycle packaging is meaningful but may need to widen to drive significant reformulation decisions, particularly for companies whose packaging choices are constrained by product protection, shelf life, or consumer convenience requirements.
Strategic Implications for Packaging Design
For packaging engineers and brand managers, eco-modulation creates a new variable in the total cost of packaging ownership. The traditional calculation — material cost, manufacturing efficiency, logistics optimization, and consumer appeal — must now include EPR fee implications across multiple states. A packaging format that saves three cents per unit in material costs but triggers higher EPR fees in Oregon, Colorado, and eventually California and Minnesota could be more expensive on a total-cost basis. This analysis becomes more complex as each state's eco-modulation rates may vary, creating the possibility that a packaging format that receives favorable treatment in one state is penalized in another. Producers should begin modeling their EPR fee exposure by material type and format across all enrolled states, using current Oregon and Colorado fee schedules as the baseline for projections.
The Circular Economy Signal
Eco-modulation represents the most direct policy mechanism for translating circular economy goals into market pricing. If fee differentials are set high enough, they can shift the economics of packaging decisions toward genuinely recyclable and recycled-content materials. If set too low, they become a marginal cost that producers absorb without changing behavior. The design of these systems — and the willingness of state regulators to approve PRO program plans with meaningful eco-modulation rates — will be one of the most important factors determining whether U.S. EPR programs actually reduce packaging waste or simply create a new revenue stream for waste management.
