A recycling company can earn two different kinds of environmental credits, and they are easy to confuse. Carbon credits for recycling represent one tonne of CO2-equivalent emissions avoided, usually because recycled material replaces virgin production. Plastic credits represent one tonne of plastic waste collected or recycled above what would have happened anyway. Both are issued by independent standards such as Verra and Gold Standard, both need third-party verification, and they answer different buyer questions.
This guide explains which credit a recycler can earn, how issuance works, what the market looked like in its most recent full year of data, and where a carbon credit platform fits once credits exist.
Can recycling companies earn carbon credits?
Yes, under specific methodologies. The main route under Verra's Verified Carbon Standard is VMR0007, a revision of the CDM methodology AMS-III.AJ for recovering and recycling materials from municipal solid waste. It was approved on 4 September 2023 and covers HDPE, LDPE, PET, PVC and PP plastics, container glass cullet, aluminium and steel.
The credited reduction comes mainly from avoided energy: making a product from recycled feedstock uses less energy than producing virgin material. For paper and cardboard, a project can also claim avoided methane if the material would otherwise decay in a disposal site. VMR0007 applies a discount factor because it is uncertain how much virgin production a recycling plant actually displaces, so a recycler should expect fewer credits than a simple tonnes-times-emission-factor calculation suggests.
Waste businesses have a second carbon route that does not involve recycling at all: landfill gas capture. The ACM0001 methodology for flaring or using landfill gas is approved by the Integrity Council for the Voluntary Carbon Market (ICVCM) under its Core Carbon Principles, which buyers increasingly treat as a quality filter.
What is a plastic credit?
A plastic credit is a separate unit with its own standard. Verra's Plastic Waste Reduction Program issues two types, each equal to one tonne of plastic waste:
- Waste Collection Credits (WCCs) for plastic collected and properly managed above the baseline.
- Waste Recycling Credits (WRCs) for plastic recycled above the baseline.
Verra issued its first plastic credits on 18 March 2022 to Second Life Thailand: more than 650 WCCs and 60 WRCs. As of October 2026, Verra's program page lists more than 40 registered projects, more than 40,000 credits issued and projects in more than 25 countries.
Plastic credits are not carbon offsets. Each one measures tonnes of plastic, not greenhouse gases, and Verra's guidance warns that terms like "plastic offsetting" or "plastic neutrality" do not accurately describe a company's impact. A brand that buys WRCs can make a clear, verifiable plastic stewardship claim; it cannot use them against its emissions.
Carbon credits vs plastic credits: what is the difference?
| Carbon credit (recycling) | Plastic credit | |
|---|---|---|
| Unit | 1 tonne CO2e avoided | 1 tonne plastic collected or recycled |
| Example standard | Verra VCS (VMR0007), Gold Standard | Verra Plastic Waste Reduction Program |
| What it proves | Lower emissions than the baseline | More plastic recovered than the baseline |
| Valid claim for the buyer | Emissions offsetting or contribution | Plastic stewardship, not carbon offsetting |
| Materials | Plastics, glass, metals, paper | Plastics only |
The same tonne of recycled PET can sit behind both a carbon calculation and a plastic calculation, so buyers and auditors will ask how a project prevents the same activity from being sold twice under two names. Settle that question in the project documentation before you approach buyers.
How does a recycler get credits issued?
The steps are broadly the same under Verra and Gold Standard:
- Choose the standard and methodology. VMR0007 with AMS-III.AJ for recycling carbon credits, the Plastic Program methodologies for plastic credits, or a Gold Standard methodology.
- Prove additionality and set a baseline. Show that the collection or recycling would not happen at this scale without credit revenue.
- Validation and registration. An accredited third-party auditor validates the project design before it is registered.
- Monitoring and verification. You record tonnages and energy data; an auditor verifies each monitoring period.
- Issuance and sale. Credits are issued into the standard's registry, then sold directly, through brokers or through a marketplace, and retired by the final buyer.
A useful benchmark is Romanian PET recycler Green Tech, which in April 2021 became the first recycling company in Europe endorsed by Gold Standard to issue carbon credits for PET recycling. Its Gold Standard project covers a 10-year crediting period with an estimated 453,000 credits, an average reduction of 45,380 tonnes of CO2 per year, which the company attributes to a 48% emission saving against virgin petroleum-based production. The credit volume is an estimate for the whole decade; actual issuance follows each verified monitoring period.
How big is the voluntary carbon market for these credits?
Smaller than most headlines suggest. Forest Trends' State of the Voluntary Carbon Market 2025 report, published in May 2025, recorded $535 million in transaction value for 2024, down 29% from 2023, on 84 million tonnes CO2e traded at an average price of $6.34. It was the lowest traded volume since 2018.
The same report shows where money is moving. Waste disposal transaction volume more than tripled, driven by demand for ICVCM-approved landfill gas credits: 3.1 million landfill gas credits traded, up 149% on 2023, and their average price rose 35% from the first half of the year to the second, after the approval. For waste and recycling projects, the lesson is that a recognised quality label now affects price more than the project category alone.

Does Article 6 of the Paris Agreement matter for recyclers?
Increasingly, yes. The Paris Agreement Crediting Mechanism under Article 6.4 approved its first credit issuance on 26 February 2026, for a clean-cooking project in Myanmar. Part of those credits are authorised for use in South Korea's emissions trading system. The UN body applied more conservative calculations, and the credited reductions came out about 40% lower than the predecessor Clean Development Mechanism would have issued.
For a recycler this means two things. Buyers with compliance or national-target use cases will ask whether a credit is authorised by the host country, and conservative recalculation is the direction of travel. Methodologies with built-in discounts, like VMR0007, are better positioned than optimistic ones.
Where do carbon credit platforms fit?
A standard's registry, such as the Verra Registry, records issuance, transfer and retirement. It does not find buyers. That is the job of a carbon credit marketplace: listing verified credits, matching them with corporate buyers, handling payment and recording retirement on the buyer's behalf. Registries are also experimenting with digital twins of credits, which is why carbon credit registries are entering blockchain.
A recycler with steady issuance has three options: sell through brokers, list on an existing exchange, or run its own sales channel. The third makes sense when you have repeat corporate buyers who want traceable, project-specific credits. Our guide on how to build a carbon trading platform covers the components, and carbon offset tokenization explains how credits become on-chain assets. 4IRE builds these systems as part of its green finance development work.
What makes a recycling credit weak?
- Weak additionality. If the recycling was already profitable without credit revenue, the credit is hard to defend.
- Overstated displacement. Assuming every recycled tonne replaces a virgin tonne inflates results; VMR0007's discount factor exists for this reason.
- Double counting. The same tonnage sold as both a carbon and a plastic credit, or claimed by both the recycler and a brand.
- Misleading buyer claims. "Plastic neutral" marketing built on plastic credits, which Verra itself discourages.
Credits that avoid these four problems sell to buyers who check, and those buyers set the price. That makes documentation quality, not tonnage alone, the asset a recycler is building. For the broader financing side, including green bonds and loans, see our notes on green finance trends.
FAQ on carbon credits and plastic credits for recycling
Yes, if it registers a project under a recognised standard and methodology, for example Verra's VMR0007 for recycling municipal solid waste or a Gold Standard methodology, passes third-party validation and verification, and has credits issued into the standard's registry. Only then can the credits be sold and retired by buyers.
A carbon credit represents one tonne of CO2-equivalent emissions avoided or removed. A Verra plastic credit represents one tonne of plastic waste collected or recycled above the baseline. Plastic credits measure plastic, not emissions, so they cannot back an emissions offset claim.
It depends on the standard and the project, because validation, registration and the first monitoring period all come before issuance. Credits are issued only after an auditor verifies a completed monitoring period, so the first revenue arrives after the first verified period, not at registration.
Mostly brands that want to fund plastic collection or recycling beyond their own obligations and make a verifiable plastic stewardship claim. Verra's first plastic credits, issued in March 2022 to Second Life Thailand, were bought by cosmetics company Caudalie.
