As extended producer responsibility (EPR) laws for packaging spread across the United States, companies are beginning to encounter a new category of packaging cost: EPR fees.
At their simplest, these fees shift some of the cost of collecting, sorting, recycling, composting, or otherwise managing packaging waste from governments and taxpayers to the companies that put packaging into the market. A producer reports how much covered packaging it supplies into a state, the packaging is classified into the appropriate material or reporting categories, and fees are assessed according to the applicable program.
But the amount of packaging a company sells is not necessarily the only thing that determines what it pays.
Increasingly, state EPR programs are being designed to consider how the packaging itself is designed. A package that is easier to recycle, contains recycled content, uses less material, or transitions to a reuse system may receive more favorable fee treatment. Conversely, packaging that interferes with recycling or has other undesirable characteristics may cost more.
That mechanism is generally known as eco-modulation.
Eco-modulation is becoming an important part of packaging EPR in the United States. Oregon and Colorado already have operative eco-modulation opportunities, while newer EPR programs in states including California, Minnesota, Maine, Maryland, and Washington establish various forms of eco-modulation that will become more important as those programs mature.
For companies trying to forecast their packaging compliance costs, the distinction between packaging fees and eco-modulation is important.
Packaging fees and eco-modulation are related—but they aren't the same thing
A useful way to think about an EPR fee is as a series of layers.
First, the packaging must be classified. A program may distinguish glass from aluminum, paper from plastic, and rigid plastic from flexible plastic. It may go considerably further and distinguish between individual resins and packaging formats.
That classification can determine the base fee.
For example, a state might charge one base rate for a clear PET bottle and a different base rate for another rigid PET package. Those different rates can reflect differences in collection, sorting, recycling, commodity value, or other program costs.
That is not necessarily eco-modulation.
Instead, a useful conceptual model is:
Packaging classification → Base material/format fee → Eco-modulation adjustment → Final producer fee
Eco-modulation is the additional incentive or disincentive layered into the fee structure based on defined environmental, design, or program criteria.
This distinction matters because it is easy to look at a detailed EPR fee schedule and assume that every difference between material rates is an eco-modulation penalty or bonus. Often it isn't. Some differences simply reflect the underlying cost of managing different packaging materials.
Eco-modulation goes a step further. It asks whether particular packaging characteristics or producer actions should cause the fee to move up or down.
What can cause an EPR fee to be eco-modulated?
There is no single national eco-modulation formula.
Each state establishes its own policy framework, and the relevant regulator and producer responsibility organization, or PRO, develop the specific fee methodology within that framework.
But several themes are appearing repeatedly in U.S. laws.
States are looking at characteristics such as recyclability, post-consumer recycled content, packaging reduction, reuse and refill, toxicity, compostability, recycling rates, and the degree to which a packaging design helps or interferes with the recycling system.
Minnesota, for example, requires future producer fees to incentivize attributes including eliminating intentionally added toxic substances, reducing packaging and paper use, increasing reuse, increasing post-consumer recycled content, and enhancing recyclability or compostability.
Washington's recently enacted program contains a similarly broad framework. Its eventual producer fees must incentivize reduced packaging, reuse, post-consumer material, recyclability and compostability, renewable inputs, and reductions in toxic substances. The law also creates a particularly interesting structural incentive for reuse: qualifying covered materials managed through a reuse system are to be charged only once, when they initially enter the marketplace.
Maryland takes a narrower approach in its enacted framework, requiring higher fees for covered materials that are not on the applicable state list or have low recycled content, and discounted fees for listed materials or materials with high recycled content.
Maine's law goes further in another direction. Its producer-payment criteria are designed to incentivize recycled content, increased recyclability, lower toxicity, packaging reduction, litter reduction, reuse, and even accurate recyclability labeling.
The result is that "eco-modulation" describes a concept rather than one standardized calculation.
And as Oregon and Colorado demonstrate, the way that concept is implemented can differ substantially from state to state.
Oregon: using life-cycle analysis to reward measurable improvements
Oregon provides one of the clearest examples of an active eco-modulation opportunity today.
Under Oregon's Recycling Modernization Act, producers pay material-specific base fees. Separately, the program allows producers to pursue eco-modulated fee reductions associated with qualifying life-cycle evaluations.
This is an important distinction.
Suppose two types of PET packaging already have different published Oregon base rates. That difference is part of the base fee structure. It does not mean that one package has received an eco-modulation bonus and the other has received a penalty.
Eco-modulation occurs on top of that structure.
Oregon's Department of Environmental Quality explains that qualifying life-cycle evaluations can be voluntarily undertaken by producers seeking fee discounts. A smaller bonus is available for evaluation and disclosure, while larger bonuses can be available when a more detailed evaluation demonstrates that a producer action—such as a packaging design change or transition from single-use to reusable packaging—achieved a substantial reduction in environmental impacts.
This creates a basic progression:
Calculate the applicable base fee → Identify a potential eco-modulation opportunity → Demonstrate qualification → Apply the fee adjustment
Oregon's approach is particularly interesting because it does not reduce packaging sustainability to a simple question like, "Does this package contain recycled content?"
The state's broader eco-modulation framework considers post-consumer content, product-to-package ratio, material choice, life-cycle environmental impacts, and relative recycling rates. Oregon's approved program plan notes that some of these attributes can already be reflected through life-cycle evaluation rather than necessarily operating as individual standalone discounts.
That means a packaging redesign might appear environmentally preferable on its face, but the producer may still need a qualifying technical analysis to establish whether it meets the requirements for a particular bonus.
This is also why eco-modulation should not be viewed as a subjective sustainability score assigned by a PRO.
The producer isn't simply sending a package to the PRO and asking someone to decide whether it is "green." The program establishes qualification rules and evidence requirements. The producer supplies the required information or analysis, and the resulting fee treatment follows the applicable methodology.
A useful analogy is claiming a tax credit. A company identifies a potentially qualifying activity, develops the required supporting evidence, demonstrates that it satisfies the criteria, and claims the resulting financial benefit.
Colorado: eco-modulation built directly into producer dues
Colorado provides a different model.
Its EPR framework requires producer dues to create incentives for better packaging outcomes and disincentives for packaging characteristics that make the recycling system more expensive or less effective.
Unlike states where the eco-modulation system is still primarily a statutory framework awaiting future implementation, Colorado has moved into an operative fee system for 2026.
That matters because Colorado illustrates two different ways eco-modulation can reach a producer: passively and actively.
Passive eco-modulation is built into the applicable dues methodology. If a reporting category meets a defined criterion—such as a high recycling rate or a recycling detriment—the applicable adjustment can flow through the fee calculation based on the packaging information the producer reports.
In that situation, there may be relatively little for a producer to "claim." The important compliance task is making sure the packaging has been classified correctly, the underlying data are accurate, and the resulting invoice reflects the correct treatment.
Active incentives are different.
Those require the producer to identify that it may qualify for favorable treatment and provide the information necessary to substantiate the opportunity.
That difference is significant for packaging teams.
A passive modifier is primarily a classification and fee-calculation problem.
An active bonus becomes an opportunity-identification, documentation, and submission problem.
And that introduces a new dimension to packaging compliance.
Eco-modulation turns packaging data into financial data
Historically, a company might maintain a packaging specification because the engineering, sourcing, quality, or manufacturing teams need to know what a package is made from.
EPR changes the value of that information.
Suddenly, the weight of a bottle, percentage of recycled resin, material used in a label, construction of a closure, recyclability of a component, or history of a packaging redesign can affect a regulatory filing—and potentially the amount the company pays.
Consider a company that lightweighted a package two years ago.
The packaging team may know the change occurred. Procurement may have the supplier specification. Regulatory may know the product is subject to EPR. Finance may be paying the PRO invoice.
But unless those pieces of information are connected, nobody may recognize that the design change creates a potential eco-modulation opportunity.
The same problem can occur with recycled content.
Knowing that a supplier uses PCR is different from knowing the verified PCR percentage, which packaging components it applies to, which SKUs use those components, how much of those SKUs entered a particular state, what evidence the applicable EPR program requires, and whether the characteristic produces a fee adjustment for the applicable fee year.
This is where eco-modulation becomes less of a sustainability concept and more of a compliance operations problem.
Not every enacted eco-modulation provision is an active opportunity yet
The rapid adoption of packaging EPR laws can also make the U.S. landscape appear more mature than it actually is.
A state can have an enacted eco-modulation requirement without yet having an operative bonus or penalty that a producer can calculate today.
Minnesota already specifies the characteristics its future producer fees must incentivize, but the state is still building out its EPR program.
Washington requires producers to join a registered PRO after July 1, 2026, but the PRO plan is not due until October 2028, with plan implementation beginning by January 2030 or within six months of approval, whichever is later. Its statute already tells us a great deal about the eventual fee structure, but that does not mean a producer can currently calculate a Washington PCR eco-modulation discount.
Maine already requires its eventual producer payments to incorporate environmental characteristics such as recyclability, recycled content and toxicity, but implementation of the stewardship organization and payment system is still developing.
California similarly establishes a much more sophisticated future eco-modulated fee structure under SB 54, but its transition matters. The regulatory framework provides for program-cost-based fees before and for a period following approval of the initial PRO plan, before the mature eco-modulated fee schedule takes over. It is also worth noting that California’s source reduction goals established under that same SB 54 are separate from its eco-modulated fee structure.
So there is an important difference between:
Eco-modulation enacted in law
and
Eco-modulation currently available or applied to producer fees.
As of 2026, Oregon and Colorado provide the clearest examples of U.S. packaging EPR programs where operative eco-modulation mechanisms are already affecting—or can directly reduce—producer fees. Other states have enacted frameworks that will make eco-modulation increasingly relevant as their programs reach later implementation stages.
Eco-modulation creates both risks and opportunities
The financial conversation around eco-modulation naturally gravitates toward discounts.
But eco-modulation works in both directions.
A package that is difficult to recycle, disrupts recycling streams, contains undesirable substances, or falls outside an approved collection system may ultimately receive a malus—an upward adjustment to its fee.
That makes eco-modulation relevant even for companies that have no interest in pursuing sustainability incentives.
There are really two questions for a producer:
Are we paying more because of the packaging we use?
and
Are we leaving available fee reductions unclaimed?
Both require good packaging data.
And as more states move from enacted legislation into operating programs, both questions are likely to become harder to answer manually.
From compliance cost to packaging decision-making
This may ultimately be the most consequential aspect of eco-modulation.
EPR fees create a price for putting packaging into a market. Eco-modulation can change that price based on packaging decisions.
That creates a feedback loop that did not previously exist:
Packaging design → Regulatory classification → EPR fee → Eco-modulation → Packaging economics
A proposed packaging redesign can therefore be evaluated not only for material cost, manufacturing performance, shipping efficiency, consumer experience, and sustainability impact, but also for its potential regulatory cost.
A packaging engineer considering two material structures might eventually be able to ask:
What would each design do to our EPR costs across the states where this product is sold?
A sourcing team evaluating a higher-PCR resin could potentially compare the increased material cost against EPR fee reductions.
A compliance team could identify a portfolio of high-fee packaging and determine which SKUs offer the greatest potential return from redesign or technical evaluation.
And finance could forecast EPR costs based not simply on how many pounds of packaging the company expects to sell, but on the characteristics of that packaging.
This is why eco-modulation should not be treated as an obscure subsection of EPR reporting.
It is the mechanism that begins connecting packaging design decisions directly to regulatory cost.
The U.S. eco-modulation landscape is only beginning to take shape
The U.S. does not yet have one standardized approach.
Oregon is developing a particularly technical, life-cycle-oriented model. Colorado is already demonstrating how passive fee modifiers and active producer incentives can operate alongside base material dues. California is building toward its own more mature eco-modulated structure. Minnesota, Maine, Maryland, and Washington have established additional approaches that will develop as their programs move toward implementation.
That fragmentation will create complexity.
A packaging characteristic that earns favorable treatment in one state may have no financial effect in another. The evidence needed to claim an incentive may differ. The same package may sit in different reporting categories. Fee schedules and eco-modulation formulas may change annually. And some opportunities will be apparent directly from packaging data while others will require additional engineering or life-cycle analysis.
For producers, the answer isn't simply to maintain a spreadsheet of eco-modulation percentages.
The underlying operational system needs to connect products, packaging components, materials, weights, supplier documentation, design changes, regulatory classifications, state fee schedules, eco-modulation criteria, evidence requirements, deadlines, and reporting years.
That is what makes eco-modulation more than a sustainability incentive.
It is becoming another recurring layer of packaging compliance—and one where better packaging data can translate directly into better financial outcomes.
