## Key Takeaways

- A scope-locked plastic reduction claim documents the accounting method, baseline, product or component, production period, and jurisdiction so the claim never exceeds its evidence.
- Physical weight allocation differs from mass balance accounting. Only physical weight allocation supports a verifiable packaging weight reduction claim.
- Baseline years stay fixed and documented before reduction is measured, and claims must remain accurate even when sales volumes change.
- Claims stay jurisdiction-specific. Language built for California SB 54 does not automatically extend to other states or retailer standards without separate substantiation.
- The Wellness Quality Institute provides independent Plastic-Free Pathway Verification that turns laboratory data into scope-locked, defensible claims for US brands.

## Who This Guide Helps And The Terms It Uses

This guide serves founders, sustainability leads, marketing heads, brand directors, and procurement leads at US consumer brands who write packaging copy or defend claims already in market. These practitioners usually have strong data. What they often lack is a clear boundary around that data. They hold laboratory reports, internal analyses, and supplier statements, yet they do not have a documented framework that converts this evidence into a claim they can defend with a retailer, a regulator, or a litigator.

Several terms appear throughout this guide. Each term is defined here in plain language.

- **Scope lock:** the practice of documenting every boundary around a claim, including what was measured, how it was measured, the baseline, the product or component, the production period, and the jurisdiction. These boundaries prevent the claim from being read as broader than the evidence.
- **Baseline:** the reference point used to measure reduction. A baseline stays fixed and documented before anyone calculates reduction.
- **Source reduction:** a decrease in the weight or volume of material used in a product or package. Under [16 CFR 260.17](https://www.ecfr.gov/current/title-16/chapter-I/subchapter-B/part-260/section-260.17) of the Federal Trade Commission’s Guides for the Use of Environmental Marketing Claims (the FTC Green Guides), marketers must avoid misrepresenting that a product or package has been reduced or is lower in weight, volume, or toxicity. They must clearly and prominently qualify source reduction claims so consumers understand the amount of the reduction and the basis for any comparison.
- **Physical weight allocation:** a method that assigns recycled or reduced plastic content based on the actual, measured weight of material in a specific product or package.
- **Mass balance:** an accounting framework that tracks recycled inputs through a manufacturing system and allocates recycled-content claims according to set rules. It does not trace individual recycled molecules into specific products.
- **PCR content:** post-consumer recycled content. This material comes from products after consumer use, not from manufacturing scrap.
- **Detection floor:** the smallest particle size or concentration a test method can reliably identify. Results below this floor do not appear in the report, yet that silence does not prove the particles are absent.
- **Reporting limit:** the minimum level at which a laboratory reports a numerical result. Results below this level usually appear as “non-detect” rather than as zero.
- **Polymer panel:** the list of plastic types a test looks for, such as polyethylene, polypropylene, PET, or polystyrene. Any polymer outside this list is not tested and cannot appear in the report.
- **Non-detect:** a laboratory result showing that a substance was not found above the method’s reporting limit. This result states a boundary and never guarantees absence.

Two regulatory frameworks give useful reference points for US brands. The [FTC Green Guides (16 CFR Part 260)](https://ecfr.gov/current/title-16/chapter-I/subchapter-B/part-260) govern environmental marketing claims nationally. [California SB 54](https://venable.com/insights/publications/2026/05/california-finalizes-long-awaited-epr-regulations), the Plastic Pollution Prevention and Packaging Producer Responsibility Act, shows how a state may structure plastic reduction requirements, including specific baseline years and reporting duties. These frameworks set the minimum level of substantiation. Brands still need to define their own claim boundaries. Laboratory capability and evidence quality limit what any claim can support, regardless of the governing regulation.

## Pillar 1: Physical Weight Boundaries For Packaging Claims

A plastic reduction claim stays defensible when it ties directly to a quantified weight or volume figure instead of a vague promise of “less plastic.”

**Rule:** A plastic reduction claim must connect to a specific weight or volume figure, not an unquantified assertion of “less plastic.”

[16 CFR 260.17](https://ecfr.gov/current/title-16/chapter-I/subchapter-B/part-260/section-260.17) defines the comparison metric for source reduction as waste entering the solid waste stream, measured by weight or volume. Its example treats “10% less waste than our previous product” as non-deceptive when the advertiser can prove that the current product’s disposal contributes 10% less waste by weight or volume than the prior version. The claim is specific, quantified, and tied to a documented comparison. Phrases like “eco-friendly packaging” or “less plastic” without a measured figure do not meet this standard.

The sharpest risk in this area comes from confusion between mass balance and physical weight allocation. Mass balance tracks recycled inputs through a system and allocates recycled attributes to outputs according to accounting rules. It does not show that any single product physically contains a stated percentage of recycled material. As [the Recycling Council explains](https://recyclingcouncil.org/insights/ccdd2h8ngfe76n6c0qvtyaqhrx1zyx-hn9mh-f6zr9-xgbf6), mass balance ensures total recycled-content claims do not exceed recycled inputs at the system level. It does not prove physical content in a specific package. A mass-balance result therefore cannot support a physical-weight reduction claim on a package. These two questions require different evidence, and mixing them turns credible data into an indefensible claim. [As of mid-2026, the US has no comprehensive federal regulation that directly governs mass-balance accounting for recycled plastic](https://processingmagazine.com/home/article/55386713/why-finding-consensus-on-mass-balancing-is-key-to-making-decarbonization-policies-and-circular-markets-work), so brands must keep the line between accounting allocation and physical measurement very clear in packaging copy.

## Pillar 2: Frozen Baselines And Honest Comparisons

Once the claim covers a defined mass, the next step is to fix the comparison period so the reduction has a stable reference point.

**Rule:** The comparison year or period stays fixed and documented before anyone measures reduction.

[16 CFR 260.17](https://ecfr.gov/current/title-16/chapter-I/subchapter-B/part-260/section-260.17) requires marketers to qualify source reduction claims clearly so consumers understand the basis for any comparison. [16 CFR 260.3(d)](https://ecfr.gov/current/title-16/chapter-I/subchapter-B/part-260/section-260.3) requires substantiation for comparative environmental marketing claims. Its Example 3 explains that when a “less waste than the leading national brand” claim rests on source reduction implemented years earlier, the advertiser must prove that the comparison still holds.

Consider a simple case. A brand reduces the plastic weight of its primary bottle by a documented percentage relative to its 2022 formulation. Sales volume then grows sharply. Total plastic entering the waste stream may rise even though the per-unit weight falls. A claim against a frozen baseline year, without adjusting for sales growth, describes a per-unit reduction. It does not describe a total reduction in plastic use. A clear statement such as “X% less plastic per bottle than our 2022 packaging” stays defensible. A broad statement such as “we have reduced our plastic use” can mislead if total output has grown.

[California SB 54 uses calendar year 2023 as its statutory baseline year for source reduction reporting](https://venable.com/insights/publications/2026/05/california-finalizes-long-awaited-epr-regulations). CalRecycle requires producers to report both the number of plastic components and the weight of plastic covered material separately for the baseline and later reports. This structure, which separates component counts from plastic weight, shows the level of documentation that supports a defensible baseline.

## Pillar 3: Jurisdictional Isolation For Market-Specific Claims

After the baseline is fixed, the claim must stay tied to the rules of the jurisdiction it was built to satisfy.

**Rule:** A claim stays within the jurisdiction whose rules it was designed to meet.

A recyclability claim illustrates this clearly. Under [16 CFR 260.12](https://ecfr.gov/current/title-16/chapter-I/subchapter-B/part-260/section-260.12), a product should be marketed as recyclable only when an established recycling program can collect, separate, or recover it for reuse or for use in manufacturing or assembling another item. The FTC’s “substantial majority” threshold for an unqualified recyclable claim requires that at least 60% of consumers or communities where the item is sold have access to recycling facilities. A package labeled “recyclable” must prove functional sorting and processing within the specific municipalities where it is sold, not only in the locations where the brand gathered recycling data.

California SB 54 shows how jurisdictional specificity works in practice. Its source reduction targets of [10% by 2027, 20% by 2030, and 25% by 2032](https://hklaw.com/en/insights/publications/2026/05/californias-final-epr-regulations-now-in-effect) apply to plastic covered material in California and use a statewide 2023 baseline. The reduction obligations operate as a collective responsibility achieved through the Producer Responsibility Organization. They do not impose individual reduction targets on each producer. A brand that builds a source reduction claim to satisfy California’s framework cannot simply extend that claim to other states with different rules or to retailer standards with their own criteria. [State attorneys general can pursue misleading environmental marketing claims under general consumer protection laws](https://purduegloballawschool.edu/blog/news/greenwashing-state-litigation), and a national package can trigger several state-specific enforcement actions at once.

## Pillar 4: Component-Level Specificity For Caps, Labels, And Liners

Clear component boundaries keep a precise claim about one part of a package from sounding like a claim about the entire package.

**Rule:** A claim about a cap, label, or liner must state that it covers that component and not the whole package.

[16 CFR 260.3(b)](https://ecfr.gov/current/title-16/chapter-I/subchapter-B/part-260/section-260.3) requires environmental marketing claims to specify whether they refer to the product, the packaging, a service, or a portion of the product or package, unless the context already makes this clear. Its example explains that labeling a plastic package containing a shower curtain “recyclable” without clarification misleads consumers if any part of the package or curtain, other than minor incidental components, cannot be recycled. The context does not reveal which item the claim covers.

Consider a bottle where the brand reduces the plastic weight of the primary bottle neck by a documented percentage while leaving the cap and label unchanged. The defensible claim reads “Primary bottle neck weight reduced by [X]%; excludes cap and label.” The broad claim “Eco-Friendly Packaging” overreaches. The first statement stays narrow enough to match the evidence. The second suggests benefits the data does not support. [16 CFR 260.4(b)](https://ecfr.gov/current/title-16/chapter-I/subchapter-B/part-260/section-260.4) explains that unqualified general environmental benefit claims are difficult to interpret and likely convey many meanings. Because marketers rarely can substantiate every reasonable interpretation, they should avoid unqualified general environmental benefit claims.

## The Reduction-Vs-Content Distinction: Packaging Weight And Microplastic Content

Packaging weight reduction and microplastic content describe two separate problems that rely on different types of evidence. Mixing them turns strong data into a risk.

A packaging weight reduction claim focuses on weight and baseline. [16 CFR 260.17](https://ecfr.gov/current/title-16/chapter-I/subchapter-B/part-260/section-260.17) and the FTC Green Guides govern this space. A defensible claim includes a quantified weight figure, a frozen baseline, a specified component, and a documented production period. The core evidence is a weight calculation.

A microplastic content claim focuses on method and detection limits. It requires an analytical method with a validated detection floor, applied to a specific product type, during a defined production or sampling period, and screening a stated polymer panel. The evidence is a laboratory result, and that result stays bounded by the method’s limits, which the claim must describe.

![Fragments of plastic suspended in blue water below the surface.](https://cdn.aigrowthmarketer.co/1784829388732-c6255482b477.webp)**Plastic doesn't disappear — it fragments. These secondary microplastics are the breakdown products of everyday objects, and independent research now detects them across the water supply. Detection, though, establishes presence, not absence.**

The California State Water Board’s drinking-water microplastics framework provides a stringent public reference for method ranges. Raman spectroscopy (SWB-MP2-rev1) is validated for particles above 20 µm through 5,000 µm. Infrared spectroscopy (SWB-MP1-rev1) is validated for particles above 50 µm through 5,000 µm. The 1–20 µm fraction falls outside both validations. [A 2026 review in Environmental Chemistry Letters](https://link.springer.com/article/10.1007/s10311-026-01902-6) confirms that accurate quantification becomes difficult when microplastic size drops below 50 µm and that the transition from microplastic to nanoplastic creates a major methodological bottleneck. [A 2026 methodological review in Microplastics](https://mdpi.com/2673-8929/5/3/167) notes that conventional FTIR spectroscopy has a practical detection limit of about 10–20 µm, while confocal Raman microscopy reaches about 1 µm spatial resolution. The authors stress that spatial resolution differs from guaranteed quantitative detection and that matrix effects, fluorescence, particle shape, polymer type, filtration losses, blanks, recovery, and spectral-match criteria all require validation.

![Colorful plastic fragments in water inside a laboratory petri dish.](https://cdn.aigrowthmarketer.co/1784829410323-fb401fc7b1e4.webp)**Microplastics are particles smaller than five millimeters. Current methods can count and identify them at the upper end of that range, but reliable measurement falls away as particles get smaller — a limit that shapes every honest claim.**

A non-detect result limits the claim to the tested particle-size range, polymer panel, method, and production lot. It never proves absence. [A 2026 critical review in MAPAN](https://link.springer.com/content/pdf/10.1007/s12647-026-00943-0.pdf) states that a “not detected” microplastic result should be qualified by the tested size window and the method-specific detection limit instead of expanded into an unqualified conclusion. A claim that a product “contains no microplastics” based on a non-detect result above 50 µm overreaches, because the method cannot see below that threshold and the absence of a finding does not equal the absence of the substance.

![Scientists in white coats working with samples and microscopes in a laboratory.](https://cdn.aigrowthmarketer.co/1784829434095-0fc8fbcf29fa.webp)**Only a small number of laboratories can genuinely test for microplastics, and capability varies by instrument and method. WQI reviews a company's existing third-party laboratory data against a defined standard — it does not run the tests itself.**

## Worked Claim Rewrites: Turning Risky Sentences Into Defensible Ones

This section shows how to convert unscoped claims into scope-locked statements using three common examples. The examples use placeholders where brands would insert actual figures.

**Packaging weight reduction claim**

- **Before:** “Our new packaging uses less plastic.”
- **After:** “The primary bottle body in our [Product Name] line weighs [X]% less than the equivalent component in our [baseline year] packaging. This reduction applies to the bottle body only and excludes the cap and label.”

The “after” version names the component, the percentage, the baseline, and the exclusions so readers do not treat it as a whole-package or company-wide claim.

**PCR content claim**

- **Before:** “Made with recycled plastic.”
- **After:** “The [component name] in this product contains [X]% post-consumer recycled [polymer type], verified by physical weight allocation from [supplier name and documentation reference]. This claim applies to [component] only and does not extend to [other components].”

The “after” version names the accounting method as physical weight allocation, not mass balance. It also specifies the component, polymer type, and documentation basis so it does not imply recycled content in untested components.

**Microplastic non-detect statement**

- **Before:** “Lab tested — no microplastics detected.”
- **After:** “Independent laboratory testing of [Product Name], [production lot or sampling period], using [method, e.g., Raman spectroscopy SWB-MP2-rev1], found no reportable target polymers detected above [reporting limit] µm within the tested particle-size range of [20–5,000 µm] and the tested polymer panel of [PE, PP, PET, PS, PVC, PA, PC, PMMA]. This result applies to the tested lot and does not establish absence of particles below the method’s detection floor or outside the tested polymer panel.”

The “after” version ties the claim to the method, particle-size range, polymer panel, and production lot so it does not suggest absence across all sizes or polymers.

## Jurisdictional Tiering For Packages Sold In Multiple Markets

Brands that ship the same package to California, to states without similar plastic reduction laws, and to retailers with their own standards face several claim environments at once. A practical solution is to tier claim language by jurisdiction instead of forcing one claim across all markets.

A tiering framework has three linked steps. Start by identifying the most stringent applicable standard for each market, because that standard sets the ceiling for what you can safely claim. California SB 54’s source reduction framework, for example, uses a 2023 baseline and requires reporting of both component counts and plastic weight, which is more granular than most current state frameworks. Next, draft claim language that meets this ceiling and qualify it to the jurisdiction where it applies. A claim built for California’s framework can appear on products sold in California, yet it should not appear as if it applies in states with different requirements. Finally, treat retailer-specific standards as separate jurisdictions with their own evidence thresholds. Many major retailers impose plastic reduction or recycled-content rules that differ from federal and state law, and a claim approved for one retailer’s scorecard does not automatically satisfy another’s.

[State-level greenwashing enforcement often focuses on marketing and product distribution that target residents within that state’s borders](https://purduegloballawschool.edu/blog/news/greenwashing-state-litigation), so a national package or website can create several state-specific enforcement exposures. The [February 2026 settlement in Arizona v. Reynolds Consumer Products](https://arizonastatelawjournal.org/2026/10/12/arizona-v-reynolds-consumer-products-inc-a-piece-of-the-national-greenwashing-puzzle), where Reynolds agreed to pay $212,000 in penalties and redesign Hefty bag packaging nationwide after Arizona alleged the bags were marketed as recyclable when they were not, shows how one state action can drive nationwide changes. Similar claims from the attorneys general of Connecticut and Minnesota highlight how states coordinate and how a single packaging claim can create multi-state exposure.

## What A Scope-Locked Plastic Reduction Claim Must Include

The four pillars above come together in six boundary elements that every scope-locked claim documents. The table below shows each element and what a brand needs on file before publishing.

| Boundary Element | What Must Be Documented |
| --- | --- |
| Accounting method | Physical weight allocation or mass balance, stated clearly, with the allocation rules documented. Mass balance does not support a physical-weight reduction claim on a package. |
| Baseline | The specific comparison year or period, fixed and documented before reduction is measured. The baseline must remain accurate over time, and any comparison against a prior product version must still hold. |
| Product or component target | The specific product, SKU, or component the claim covers. A claim about a cap, label, or liner applies to that component only. A single-product result does not extend to a product line or the company. |
| Production period | The specific production lot, sampling period, or date range the evidence covers. A result from one production lot does not guarantee performance in later lots. |
| Jurisdiction | The specific market or markets where the claim applies and the regulatory or retailer standard it was built to satisfy. A claim built for one jurisdiction requires separate substantiation before use in another. |
| Supporting evidence | For weight reduction: a documented weight figure, a frozen baseline, and a specified component. For microplastic content: the analytical method, validated particle-size range, polymer panel, reporting limits, blank results, spike recoveries, chain of custody, and laboratory accreditation. For PCR content: the chain-of-custody model, the component scope, and the documentation basis. |

The Wellness Quality Institute (WQI) offers an independent review program, the Plastic-Free Pathway Verification (PFPV) governed by WQI-CS-01, that turns a company’s existing third-party laboratory dataset into a scope-locked, defensible position. The Wellness Quality Institute reviews the dataset, method, product scope, and supporting controls against criteria focused on particle size and polymer type, aligned with the California State Water Board’s drinking-water microplastics framework. Every decision ties back to a defined Verification Scope, which includes the specific product or SKU, matrix, production or sampling period, analytical method, tested particle-size range, polymer panel, reporting limits, and supporting controls. The program does not allow a company-wide or product-line claim to grow out of a single dataset. Products that meet the standard receive a verification decision, a scope-locked mark license, a public registry listing with a searchable registry ID, and approved claim language. The Wellness Quality Institute does not run laboratory tests. Independent laboratory testing is arranged and billed separately. Verification is available to US companies nationally, with California serving as a technical reference point rather than a geographic limit.

*WQI Plastic-Free Pathway Verification does not certify that a product contains zero plastic, microplastics, or nanoplastics. It shows that the company is on a verified pathway toward plastic-free standards. Verification applies only to the reviewed products, submitted datasets, tested ranges, polymer panels, production or sampling periods, and supporting controls. WQI verification is not a California approval, government certification, or health or safety certification.*

## Frequently Asked Questions

### What Does Scope Locking Mean?

Scope locking means documenting every boundary around a plastic reduction claim before publishing it. These boundaries include the accounting method used to calculate reduction, the baseline for comparison, the specific product or component covered, the production period reflected in the evidence, and the jurisdiction whose standards the claim satisfies. A claim without documented boundaries can easily read as broader than the evidence, which turns credible data into a greenwashing risk. Scope locking uses the evidence a company already has and maps it to explicit limits so the claim language reflects those limits instead of implying more.

### Is A Scope-Locked Claim A Certification?

A scope-locked claim is a substantiation discipline, not a certification. It describes a way of drafting and documenting a claim so it stays within what the evidence supports. It does not equal a government approval or a third-party endorsement. A brand can scope-lock its own claims using its laboratory data and internal records. Independent review programs, such as the Wellness Quality Institute’s Plastic-Free Pathway Verification, add a neutral party that checks whether the boundaries are defensible and whether the evidence supports the drafted claim. That review converts a self-reported position into an independently reviewed one, which regulators and retailers tend to treat as more credible.

### How Long Does A Baseline Stay Valid?

A baseline remains valid while the comparison it supports stays accurate. Under [16 CFR 260.3(d)](https://ecfr.gov/current/title-16/chapter-I/subchapter-B/part-260/section-260.3) of the FTC Green Guides, a marketer claiming its packaging creates less waste than a competitor’s must prove that the comparison still holds when the source reduction occurred years earlier. The same logic applies to a brand’s own prior product. If the baseline product has been reformulated, discontinued, or replaced, the comparison may no longer work. [California SB 54 uses calendar year 2023 as its statutory baseline year and requires annual source reduction reporting against that baseline](https://hklaw.com/en/insights/publications/2026/05/californias-final-epr-regulations-now-in-effect), which shows how regulators expect baselines to be maintained and updated. For microplastic content claims, the Wellness Quality Institute’s Plastic-Free Pathway Verification uses a 24-month verification period from the sampling date of the most recent accepted dataset. This approach reflects the reality that a result describes the production it came from and that lot-to-lot variability means older results do not guarantee current performance.

### What Does A Non-Detect Result Actually Bound?

A non-detect result sets boundaries along four dimensions: the tested particle-size range, the polymer panel, the analytical method, and the sampled production lot. It does not speak to plastic particles below the method’s detection floor, outside the tested size range, outside the polymer panel, or in other production lots. As noted earlier, neither validated method covers the 1–20 µm fraction. A non-detect result above 50 µm using infrared spectroscopy therefore says nothing about particles between 1 µm and 50 µm. A claim that a product “contains no microplastics” based on such a result stretches the evidence beyond what the method can see.

### How Do I Handle Multi-Jurisdiction Claims?

The most reliable approach is to tier claim language by jurisdiction instead of using a single claim everywhere. Identify the most stringent applicable standard for each market where the product is sold. Draft claim language that meets that standard and qualify it to the jurisdiction where it applies. Avoid extending a claim built for one jurisdiction into another without fresh substantiation. For retailer-specific standards, treat each retailer’s supplier requirements as its own jurisdiction with its own evidence threshold. A claim that passes one retailer’s review does not automatically pass another’s. Because state attorneys general can pursue misleading environmental marketing claims under general consumer protection laws, a national package can create several state-specific enforcement exposures, so careful qualification usually costs less than an investigation.

### What Happens When A Claim Covers A Component Rather Than A Whole Package?

A component claim often gives the clearest and most defensible plastic reduction story, as long as the claim states that it covers a component. Under 16 CFR 260.3(b) of the FTC Green Guides, an environmental marketing claim must specify whether it refers to the product, the packaging, or a portion of either, unless context already makes this obvious. A claim that the primary bottle body weighs less than the previous version stays defensible when it says so directly. The same data becomes risky when the language suggests a whole-package or whole-product reduction that the evidence does not show. The practical rule: claim language must match the evidence boundary exactly. If the evidence covers the bottle body, the claim covers the bottle body. If the evidence covers the cap, the claim covers the cap.

      - **Text:** A baseline remains valid while the comparison it supports stays accurate. Under 16 CFR 260.3(d) of the FTC Green Guides, a marketer claiming its packaging creates less waste than a competitor's must prove that the comparison still holds when the source reduction occurred years earlier. The same logic applies to a brand's own prior product. If the baseline product has been reformulated, discontinued, or replaced, the comparison may no longer work. California SB 54 uses calendar year 2023 as its statutory baseline year and requires annual source reduction reporting against that baseline, which shows how regulators expect baselines to be maintained and updated. For microplastic content claims, the Wellness Quality Institute's Plastic-Free Pathway Verification uses a 24-month verification period from the sampling date of the most recent accepted dataset. This approach reflects the reality that a result describes the production it came from and that lot-to-lot variability means older results do not guarantee current performance.
    **Question:**

    - **Name:** What Does A Non-Detect Result Actually Bound?
      **Answer:**

      - **Text:** A non-detect result sets boundaries along four dimensions: the tested particle-size range, the polymer panel, the analytical method, and the sampled production lot. It does not speak to plastic particles below the method's detection floor, outside the tested size range, outside the polymer panel, or in other production lots. As noted earlier, neither validated method covers the 1–20 µm fraction. A non-detect result above 50 µm using infrared spectroscopy therefore says nothing about particles between 1 µm and 50 µm. A claim that a product “contains no microplastics” based on such a result stretches the evidence beyond what the method can see.
    **Question:**

    - **Name:** How Do I Handle Multi-Jurisdiction Claims?
      **Answer:**

      - **Text:** The most reliable approach is to tier claim language by jurisdiction instead of using a single claim everywhere. Identify the most stringent applicable standard for each market where the product is sold. Draft claim language that meets that standard and qualify it to the jurisdiction where it applies. Avoid extending a claim built for one jurisdiction into another without fresh substantiation. For retailer-specific standards, treat each retailer's supplier requirements as its own jurisdiction with its own evidence threshold. A claim that passes one retailer's review does not automatically pass another's. Because state attorneys general can pursue misleading environmental marketing claims under general consumer protection laws, a national package can create several state-specific enforcement exposures, so careful qualification usually costs less than an investigation.
    **Question:**

    - **Name:** What Happens When A Claim Covers A Component Rather Than A Whole Package?
      **Answer:**

      - **Text:** A component claim often gives the clearest and most defensible plastic reduction story, as long as the claim states that it covers a component. Under 16 CFR 260.3(b) of the FTC Green Guides, an environmental marketing claim must specify whether it refers to the product, the packaging, or a portion of either, unless context already makes this obvious. A claim that the primary bottle body weighs less than the previous version stays defensible when it says so directly. The same data becomes risky when the language suggests a whole-package or whole-product reduction that the evidence does not show. The practical rule: claim language must match the evidence boundary exactly. If the evidence covers the bottle body, the claim covers the bottle body. If the evidence covers the cap, the claim covers the cap.
