CARBON MARKETS & CLIMATE PROJECTS
A plastic credit represents one tonne of plastic waste collected from the environment or recycled into new material by an independently verified project — issued under a recognized plastic credit standard such as Verra's Plastic Waste Reduction Standard (PWRS), the Plastic Credit Exchange (PCX), Zero Plastic Oceans' Verified Plastic Standard, or BVRio. Plastic credit projects are increasingly engaged by consumer goods brands, packaging manufacturers, and retailers addressing plastic in their value chains — driven by Extended Producer Responsibility (EPR) schemes, voluntary plastic commitments, and disclosure obligations under ESRS E5 (Resource use and circular economy), GRI 306, and CDP's Plastics module. The credibility of a plastic credit programme depends entirely on the integrity of the underlying projects — the standard they are registered under, the methodology applied, the additionality and traceability of the waste flows, and the independence of the verification.
Semtrio develops plastic credit projects from concept through verified credit issuance — covering collection and recycling pathways, designing project methodology to the appropriate recognized standard, managing independent validation, and supporting projects through monitoring, verification, and credit registration. We are methodology-agnostic: the standard and methodology are selected to fit the project's pathway, geography, and intended buyer market — not the other way around.
Verra's Plastic Waste Reduction Standard (PWRS), the Plastic Credit Exchange (PCX), Zero Plastic Oceans' Verified Plastic Standard, BVRio, and other emerging schemes operate with different methodologies, additionality requirements, and verification frameworks. Standards differ in their treatment of collection vs. recycling pathways, baseline definitions, leakage requirements, and the rigour of independent third-party verification. Plastic credit projects registered under standards without recognized methodology depth or independent verification carry significant credibility risk — including from regulators, brand procurement teams, and disclosure assurance providers increasingly scrutinizing claims that depend on credit instruments.
Brands and manufacturers building plastic credit programmes without first addressing upstream plastic use through reduction, redesign for circularity, reuse models, and recycled content commitments face a structural credibility problem. Voluntary commitment frameworks, ESG rating agencies, NGO scrutiny, and the disclosure environment under ESRS E5, GRI 306, and CDP's Plastics module increasingly treat plastic credits as a residual offset for unavoidable plastic — not as a substitute for upstream action. The brands maintaining the strongest credit programmes are those running the strongest reduction and circular design programmes alongside them — and the projects most defensible against future scrutiny are those developed for buyers who have already done the upstream work.
The EU Packaging and Packaging Waste Regulation (PPWR), national Extended Producer Responsibility (EPR) schemes across the EU, UK, and emerging markets, the in-progress UN Global Plastics Treaty, ESRS E5 (Resource use and circular economy), GRI 306 (Waste), and CDP's Plastics Disclosure module are creating overlapping, accelerating pressure on brands and packaging manufacturers to demonstrate measurable, verifiable plastic outcomes — not commitment statements. Verified plastic credit projects under recognized standards are part of the response to that pressure, alongside reduction and redesign — but only when the underlying projects meet the integrity threshold the disclosure and assurance environment now requires.
The plastic credit market is at the stage of development the voluntary carbon market was in a decade ago — fragmented standards, inconsistent methodologies, and rising scrutiny from buyers, regulators, and assurance providers. The projects that endure that scrutiny are designed from the outset to the integrity criteria credible buyers and disclosing organizations apply: clear additionality, traceable waste flows, independent third-party verification, defensible baseline assumptions, and methodology fit between the project pathway — collection or recycling — and the standard the project is registered under.
Semtrio develops plastic credit projects to that standard. We assess project pathway and feasibility against the standards landscape, recommend the standard and methodology best suited to the project's geography, technology, and intended buyer market — rather than defaulting to a single framework — and manage the project through validation, registration, monitoring, and verification to credit issuance. Project development decisions are made with the disclosure and assurance environment the buyer faces in view: a credit project that is credible to the buyer's CDP scoring, ESRS E5 disclosure, and GRI 306 reporting from day one is a credit project that holds its value.
OUR PROCESS
Plastic credit project development — collection and recycling pathways, end-to-end from concept through verified credit issuance.
Brands and manufacturers developing plastic credit programmes need a measured plastic footprint as the baseline — without quantified plastic flows across the value chain, credit volume design and post-issuance claims have no defensible reference point. LCA-grade plastic flow analysis underpins both reduction strategy and credit programme design.
Learn moreESRS E5 — Resource use and circular economy — requires undertakings to disclose plastic flows, circular economy actions, and the role of credit instruments where used. Plastic credit programmes that are not designed with E5 disclosure expectations in view create downstream reporting risk. Semtrio designs credit projects and ESRS E5 disclosure as a connected programme.
Learn moreGRI 306 (Waste) requires organizations to disclose waste-related impacts, the actions taken to address them, and any credit instruments used. Plastic credit programmes that connect cleanly to GRI 306 disclosure produce the reporting evidence sustainability statements and ESG rating processes require.
Learn moreCDP's Plastics Disclosure module rewards organizations reporting verified plastic commitments and credible credit programmes — not self-claimed offsets or unsupported neutrality claims. Standard-registered, third-party-verified plastic credit projects are positioned strongly on CDP's Plastics scoring criteria.
Learn more40,000 tonnes of plastic addressed under Verra's Plastic Waste Reduction Standard. 250,000 tonnes of CO₂ avoided across registered carbon projects. Active project development — methodology-agnostic, integrity-led.
Semtrio operates plastic and carbon credit project work as a single project development discipline — drawing on the same methodology, validation, and standards-process expertise across both. Our active plastic credit project portfolio under Verra's Plastic Waste Reduction Standard addresses 40,000 tonnes of plastic across recycled plastic pathways. That work sits alongside 250,000 tonnes of CO₂ avoided across registered carbon projects under Gold Standard and Verra. Plastic credit project development is not a peripheral capability — it is part of an active project portfolio with the methodology depth, validation experience, and verification track record that registered project development requires.
Our approach is methodology-agnostic. We assess the standard and methodology best suited to each project's pathway, geography, and intended buyer market — Verra PWRS, Plastic Credit Exchange, Zero Plastic Oceans, BVRio — rather than defaulting to a single framework. Project development decisions are made with the integrity criteria credible buyers and disclosing organizations apply: clear additionality, traceable waste flows, independent third-party verification, defensible baseline assumptions, and methodology fit between the project pathway and the standard.
For brands and manufacturers developing plastic credit programmes as part of broader plastic strategies, the credibility of the credit project is the credibility of the programme. We design plastic credit projects that are defensible to procurement teams, disclosure assurance providers, and the regulatory and reputational scrutiny credit-based plastic claims now face — alongside the reduction, redesign, recycled content, and circular design strategies that any credible plastic strategy depends on first.

Frequently asked questions about plastic credit project development
A plastic credit represents one tonne of plastic waste collected from the environment or recycled into new material by an independently verified project — registered under a recognized plastic credit standard. Plastic credit projects fall into two main pathways: collection (capturing plastic waste before it reaches the environment, typically in geographies with weak waste management infrastructure) and recycling (processing plastic waste into recycled material, displacing virgin plastic production). The credibility of a plastic credit depends on the standard it is registered under, the methodology applied to baseline and additionality, the traceability of the underlying plastic flows, and the independence of the third-party verification. Recognized standards include Verra's Plastic Waste Reduction Standard (PWRS), the Plastic Credit Exchange (PCX), Zero Plastic Oceans' Verified Plastic Standard, and BVRio — each with different methodologies, project boundaries, and verification frameworks. Semtrio's active plastic credit portfolio addresses 40,000 tonnes of plastic under Verra PWRS through recycled plastic pathway projects.
Collection-based projects address plastic waste at the point of capture — typically in geographies where existing waste management infrastructure does not prevent leakage to the environment. The credit is generated by the verified collection of plastic waste that would otherwise have reached oceans, waterways, landfills, or open dumping. Recycling-based projects address plastic waste through processing into recycled material that displaces the production of virgin plastic — the credit is generated by the verified recycling of plastic waste streams into recycled material outputs. The two pathways have different baseline scenarios, additionality arguments, and methodology requirements, and recognized standards approach them with different methodologies. The choice of pathway depends on the project's geography, available waste streams, technology infrastructure, and intended buyer market — and the methodology selected has to fit both the pathway and the standard. Semtrio's current plastic credit project work covers recycled plastic pathways under Verra's Plastic Waste Reduction Standard.
The plastic credit market includes several recognized standards: Verra's Plastic Waste Reduction Standard (PWRS), the Plastic Credit Exchange (PCX), Zero Plastic Oceans' Verified Plastic Standard, BVRio, and others operating regionally or for specific project types. Standards differ in their methodologies, treatment of collection vs. recycling pathways, baseline definitions, additionality requirements, leakage treatment, and verification rigour. Semtrio is methodology-agnostic — we assess the standard and methodology best suited to each project rather than defaulting to a single framework. Selection criteria include the project's pathway and technology, geographic context, waste stream characteristics, the intended buyer market (some buyers have explicit standard preferences or exclusions), the disclosure framework the buyer reports under (CSRD/ESRS E5, GRI 306, CDP Plastics), and the standard's methodology fit. The right answer is the standard that produces the most credible, defensible, and commercially viable credit outcome for the specific project — which is rarely the same answer for two different projects.
Plastic credits are a residual instrument within a credible plastic strategy — sitting alongside, not replacing, upstream reduction, redesign for circularity, reuse models, and recycled content commitments. Brands and manufacturers using plastic credits as a substitute for upstream action face significant credibility risk — from voluntary commitment frameworks, NGO scrutiny, ESG rating agencies, and the disclosure environment under ESRS E5, GRI 306, and CDP's Plastics module. Used correctly, plastic credit projects address the share of plastic in the value chain that cannot reasonably be reduced, redesigned, or reused, and produce the verified, traceable evidence that disclosure frameworks and stakeholder communication require. Extended Producer Responsibility (EPR) schemes — the EU PPWR, national EPR regulations, and equivalent emerging frameworks — increasingly reference verified credit projects as part of compliance instruments, although the regulatory treatment varies by jurisdiction. Semtrio designs plastic credit projects with the disclosure environment, EPR landscape, and brand commitment frameworks in view — so the project credentials connect cleanly to the buyer's reporting and compliance obligations.
Semtrio's plastic credit project development process follows four phases. We begin with concept assessment and feasibility — evaluating the project pathway (collection or recycling), waste flow characteristics, geographic and technology context, baseline scenario, additionality argument, and expected credit volumes — and recommending the standard and methodology best suited to the project. We confirm the standard selection and design the project methodology to the standard's requirements: collection projects covering waste capture, traceability, and end-of-life; recycling projects covering waste inputs, recycled outputs, displacement of virgin production, and verification chain. We develop the project document, manage independent validation, and complete standard body registration. We manage the monitoring and verification cycle through to verified credit issuance. Throughout the process, the project is designed to the integrity threshold credible buyers, regulators, and disclosure assurance providers apply — additionality, traceability, independent verification, defensible baselines, and methodology fit are designed in from concept, not retrofitted at verification.
