The two certifications that matter.
FSC (Forest Stewardship Council) and PEFC (Programme for the Endorsement of Forest Certification) are the two independent chain-of-custody standards used across the paper industry. Both certify that the fibre came from a managed forest, tracked from stump to sheet. FSC has the stricter environmental and social criteria and the broader recognition in Europe; PEFC has broader coverage in North America and eastern Europe. Neither is greenwashing. If a ream carries one of these logos, the fibre has a documented origin.
The three FSC variants.
- FSC 100%. Every fibre in the ream came from an FSC-certified forest. The strongest claim.
- FSC Recycled. Every fibre is recycled from post-consumer waste. No new tree was cut for this ream.
- FSC Mix. A blend of FSC virgin fibre, FSC recycled fibre, and "controlled sources" — untraced fibre that has been audited to not come from illegal logging or protected forest. Most office paper labelled FSC is FSC Mix.
FSC Mix is not a lie, but it is not the same as FSC 100%. A typical FSC Mix ream is 30–70% certified and the rest is controlled. If your ISO 14001 audit or your procurement policy requires a specific number, buy 100% or Recycled, not Mix.
Post-consumer waste percentages.
"Recycled" on its own means very little — sawmill offcuts count as recycled content, and those never touched a consumer. The number that matters is PCW (post-consumer waste): the percentage of the ream that was once a printed page, a newspaper, or a cardboard box someone threw away and a recycler picked up. A ream labelled "50% PCW" contains half post-consumer fibre; the rest can be pre-consumer (mill offcuts) or virgin.
Common tiers we stock: 30% PCW (roughly the same cost and printability as virgin), 50% PCW, and 100% PCW. 100% PCW is slightly rougher on the sheet, drops about 3–5% in whiteness (CIE 150 vs CIE 165 for virgin), and costs 5–8% more. Whether that matters depends entirely on what you print.
Labels to ignore.
- "Eco" without a percentage. Meaningless. A brand name choice, not a claim.
- "From sustainable forests" with no certification. Undefined. Every forest could be called sustainable by its owner.
- "Chlorine-free" on office paper. True of every EU-made office paper for the past two decades — it is a regulatory floor, not a distinguishing claim.
- Carbon-neutral by offsetting. Offsets are a separate purchase from the paper. A carbon-neutral claim tells you the manufacturer bought offsets; it says nothing about the fibre.
How to actually buy.
For general copier work: FSC Mix 80gsm virgin is fine, and it prints identically to recycled. For any print that leaves your building on client-facing paper (contracts, proposals): FSC 100% virgin 100gsm or heavier. For internal-only volume printing where you want the sustainability marker on your procurement policy: FSC Recycled 100% PCW 80gsm — accept the 3% whiteness drop and put it in your policy document.
Every paper SKU we list shows its certification and PCW number on the product page. If the number is missing, it means the manufacturer did not publish it and we would rather say so than make one up.
