Corporate plastic neutrality: case studies and lessons

Why corporate plastic neutrality matters now

Plastic neutrality — the commitment to collect or recycle an amount of plastic equivalent to what a company places on the market — has moved from a niche sustainability experiment to a mainstream corporate strategy. Driven by tightening regulation, investor pressure, and consumer demand, major brands have launched structured plastic neutrality programs backed by certified plastic credits. But not all programs are equal. This review examines three leading corporate programs, drawing out the design choices that determine credibility and longevity.

HP Inc — Planet Partners

HP Inc operates one of the most mature and publicly documented corporate plastic recovery programs in the technology sector. Its Planet Partners take-back scheme accepts HP-branded hardware, toner cartridges, and print supplies for responsible end-of-life processing. The plastic neutrality dimension of Planet Partners is anchored in two parallel tracks: physical incorporation of ocean-bound recycled plastic into new HP products, and the retirement of Prevented Ocean Plastic (POP) credits for volumes that cannot yet be incorporated directly.

HP's headline commitment — collecting and recycling 1.2 billion kilograms of HP-brand plastic waste by 2025 — is notable for its specificity. The target covers only HP-brand plastic, not all plastic that HP handles, which is a transparent scoping decision that limits overclaiming. As of HP's 2023 Sustainable Impact Report, cumulative collection had reached 873 million kilograms, representing roughly 73% of the 2025 target. The company discloses collection volumes by material type and product category in its annual reporting, enabling independent scrutiny.

The credibility architecture of Planet Partners rests on a dual-track model. Products including monitors, personal computers, and laptops carry on-pack labels indicating the percentage of ocean-bound plastic used in their construction — plastic physically incorporated into the product itself, verified through chain-of-custody documentation. Credit retirement covers the gap between what can be physically incorporated and the total collection commitment. HP uses Verra-registered POP credits, retiring serial numbers publicly traceable on the Verra registry.

Key lesson: Integrating physical recycled content alongside credit-based offsets is substantially more credible than a credits-only approach. Physical incorporation demonstrates investment in supply chain transformation; credits complement but do not substitute for this effort. Brands considering plastic neutrality programs should regard physical content targets as primary and credit retirement as a residual mechanism.

Henkel — SKU-level plastic neutrality

Henkel, the German consumer goods group behind brands including Persil, Pritt, and Schwarzkopf, has pursued a distinctive approach to plastic neutrality: rather than making a single company-wide claim, Henkel certifies individual stock-keeping units (SKUs) as plasticneutral. The certification is delivered through the Verra Plastic Waste Reduction Standard (PWRS), with Henkel purchasing and retiring PWRS credits corresponding to the plastic footprint of specific products.

The Pritt glue stick range and selected Persil laundry formats have carried the plasticneutral certification label in European markets since 2021. Henkel's broader packaging commitment — that all plastic packaging will be recyclable or reusable by 2025 and contain at least 35% recycled content — provides a reduction trajectory that gives the credit purchases context. Credits are presented as a bridge mechanism while packaging redesign matures, not as a permanent substitute for redesign.

The SKU-level approach addresses a vulnerability common to portfolio-wide plastic neutrality claims. A portfolio claim invites questions about which products are subsidising which, and whether low-footprint SKUs are being used to offset high-footprint ones. By certifying at SKU level, Henkel makes its methodology auditable at the product level. Retailers and regulators can verify the credit retirement for Pritt independently of any other Henkel product line, reducing the risk of blended accounting.

Key lesson: SKU-level certification is more defensible under regulatory and consumer scrutiny than portfolio claims. As the EU Green Claims Directive comes into force from 2026 — requiring environmental claims to be substantiated by specific, verifiable evidence — product-level credit accounting will be better positioned than company-wide averages.

L'Oréal — geographic market matching

L'Oréal achieved plastic neutrality for its rinse-off product portfolio across five markets — France, Germany, the United Kingdom, China, and the United States — in 2022, partnering with rePurpose Global to source certified plastic credits from collection and processing projects in India and Indonesia. The certified offset volume corresponded to approximately 70 million units of rinse-off packaging placed on those five markets during the relevant reporting year.

L'Oréal's approach introduces a geographic dimension that is underused in corporate plastic neutrality programs. By sourcing offsets from India and Indonesia — two of the top five contributors to ocean plastic pollution globally — the company argues that its credit purchases address plastic leakage risk in regions where plastic recovery infrastructure is most deficient, while its product sales occur in markets with higher baseline recovery rates. This is not geographic matching in the strict sense (projects are not co-located with markets), but it reflects additionality reasoning: credits from high-leakage regions prevent more plastic from reaching waterways than credits from markets where recovery rates are already above 80%.

rePurpose Global provided project-level reporting on collection volumes, waste picker engagement, and material end destinations, published on rePurpose's impact registry. L'Oréal incorporated these data points into its 2022 sustainability disclosures, providing investors and NGOs with a traceable evidence chain.

Key lesson: Sourcing credits from regions where plastic leakage risk is highest strengthens additionality arguments and narrative coherence. Brands should be able to explain why their chosen projects deliver environmental value that would not occur otherwise — geographic high-risk targeting is one defensible rationale.

Common challenges across all programs

Despite their differences, HP, Henkel, and L'Oréal face a shared set of structural challenges. Scope 3 plastic data — the plastic embedded in upstream supply chains and downstream product use — remains difficult to quantify with precision, meaning program boundaries inevitably involve methodological choices that are contestable. Credit quality varies significantly across project types and standard bodies, requiring brands to exercise due diligence on the projects backing their certificates. Consumer comprehension of plastic neutrality remains low relative to carbon neutrality, complicating on-pack communication. And vintage management — ensuring that credits retired correspond to the reporting period in which plastic was placed on market — requires administrative discipline that not all programs have demonstrated.

What good programs share

Across these case studies, the programs that have withstood scrutiny share a common architecture. They measure plastic footprint before purchasing offsets, using a defined and documented methodology. They set and disclose reduction targets alongside credit retirement, treating credits as a residual mechanism rather than a primary strategy. They use credits registered on public standards with serial numbers that are independently verifiable. And they communicate transparently about what plastic neutrality does and does not mean — specifying the scope, the boundary conditions, and the standard applied. As regulatory expectations harden, this transparency framework will become not a differentiator but a baseline requirement.
