ISO 20121:2024 & Net Zero Events: 2026 Badge Standards

Why 2026 is the year event sustainability got a global rulebook upgrade

Two global frameworks are converging on the same thing: procurement.

ISO 20121:2024 is a certification standard. Net Zero Carbon Events is a voluntary pledge with public reporting attached. They work differently, but they're both pointing the same direction. Show your evidence, or don't bother claiming it.

If you've read our piece on the UK's Green Events Code of Practice, think of that as the local council rulebook. ISO 20121 and Net Zero Carbon Events are the international layer sitting above it, and they apply whether you're running an event in Solihull or Singapore.

This isn't a niche concern either. UFI's Status of Sustainability report puts sustainability as a top mid-term priority across the entire global exhibition industry. Not a nice-to-have. A priority.

The direction of travel is unmistakable: evidence over claims. If your badge supplier is still leaning on marketing copy instead of certified data, that's a problem you need to fix in 2026, not 2027.

ISO 20121:2024: what actually changed

The countdown clock: 31 March 2027

ISO 20121:2024 was published in April 2024, formally replacing ISO 20121:2012 (ISO 20121:2024; ISO 20121:2012). Under standard ISO transition rules, certified organisations get three years to move across. That window closes on 31 March 2027.

Here's the thing. Eight months feels like plenty of time. It isn't, not once you factor in gap analysis, policy updates and a full recertification audit. Miss the deadline and your certificate doesn't just lapse quietly. You go back to square one with a full Stage 1 and Stage 2 assessment, which costs real money and real time.

If you're still certified to the 2012 version, 2026 is your working year, not 2027.

The supply chain gets scrutinised, not just the organiser

This is the change that actually matters for badge procurement.

Under the old standard, self-declaration was often good enough. A supplier said their material was recyclable, and that was that. ISO 20121:2024 tightens this considerably. Suppliers now need to show evidence during procurement, and sponsors and in-kind partners are pulled into governance scope too (ISE World; BSI).

Think of it like a food hygiene inspection. Nobody accepts "trust me, the kitchen's clean" anymore. You want the certificate on the wall.

For a badge supplier brief, that means asking for certified material data, not marketing claims. EN13432 certification. Verified recyclability data. A real carbon footprint, not a rounded-off estimate.

The International Monetary Fund achieved ISO 20121 certification for its Annual Meetings, and it's a decent model for what evidence-based procurement looks like when you scale it up. No self-declared claims. Verified data, top to bottom.

If your current badge checklist doesn't already cover this, start with our practical badge checklist for plastic-free conferences.

The Net Zero Carbon Events pledge: the 2026 reporting wave

What signatories committed to

Signatories to Net Zero Carbon Events commit to publishing a pathway to net zero by 2050 at the latest, with an interim target of a 50% GHG reduction by 2030, in line with the Paris Agreement. They have roughly 18 months from signing to get that pathway published.

The initiative is hosted by the Joint Meetings Industry Council (JMIC) and listed on the UNFCCC Global Climate Action Portal. That's not a badge you can quietly ignore. It's a globally tracked commitment.

Organisations that signed in 2024 and 2025 are hitting that 18-month publication window right through 2026. If your event partners or venues signed the pledge recently, expect them asking harder questions about your supply chain this year.

Why badges and credentials are back on the agenda

Materials sit inside a signatory's Scope 3 emissions, the same category our conference badge checklist already covers for the UK market. The difference now is that it's attached to an international pledge with public reporting, not just good intentions.

It's worth being clear on the distinction, because the two frameworks get muddled constantly:
 

What this means for your event badge procurement brief in 2026

Translate both frameworks into a supplier requirement list and it looks like this:

• EN13432 certification on any compostable or biodegradable claim
• Independently verified carbon data, not a supplier estimate
• Recyclability evidence, tested and documented
• Zero self-declared claims accepted at face value

Take a look at our event passes and full specifications if you want to see what evidence-based procurement actually looks like on paper rather than in theory.

We built our own model around independent verification specifically because of where this industry is heading, working with Carbon Quota and DS Smith rather than making claims ourselves. You can read more on how we're approaching transparent sustainability in event badges.

There's also a quieter win hiding in here. On-demand printing removes pre-print waste from your carbon calculation entirely. No unused badge stock heading to landfill after the event. Our partnership with Cvent was built around exactly this, printing what's needed, when it's needed.

A short timeline for 2026 to 2030

• 2026 — Wave of Net Zero Carbon Events signatories from 2024/2025 hit their 18-month pathway publication deadline
• 31 March 2027 — ISO 20121:2012 transition period closes for good; only ISO 20121:2024 remains valid
• 2030 — Net Zero Carbon Events interim target: 50% GHG reduction industry-wide
• 2050 — Net Zero Carbon Events long-term target: net zero

Your Next Steps

Two frameworks, one direction. Evidence over claims, everywhere you look.

If your badge supplier can't hand you certified material data on request, that's not a small gap. It's the exact gap both frameworks were built to close.
