TRUE vs Zero Waste Europe Certification: which Zero Waste standard is right for your facility?
If your organisation is serious about zero waste, sooner or later the question comes up: how do we prove it? Two credible answers dominate the conversation: TRUE certification for Zero Waste, administered by GBCI (the body behind LEED), and the Zero Waste Business Certification from the Mission Zero Academy (MiZA), built on Zero Waste Europe's methodology.
Both are independent, third-party-assessed standards rooted in the zero waste hierarchy. But they take noticeably different routes to get there, and for facilities managers and sustainability leads, choosing the right one depends on where your sites are, how mature your waste programme is, and what you need the certification to do for you.
What is TRUE certification?
TRUE (Total Resource Use and Efficiency) is a global, facility-level rating system. It certifies a physical site (a "project" defined by its property boundary) rather than the organisation or its products.
TRUE is fundamentally performance-based. To certify, a project must meet five minimum programme requirements, the headline one being an average 90% diversion from landfill, incineration and the environment over the most recent 12 months, with no material stream exceeding 10% contamination. On top of that, projects earn points across 81 credits in 15 categories (from redesign and reuse to purchasing, training and leadership), with four levels: Certified (31 points), Silver, Gold and Platinum.
For sites not yet at 90% diversion, TRUE precertification offers a stepping stone: it recognises the foundational policies, audits and plans without requiring a minimum diversion rate, and is valid for three years.
What is the Zero Waste Europe (MiZA) certification?
The Zero Waste Business Certification is Europe's answer, run by the Mission Zero Academy, the capacity-building hub affiliated with Zero Waste Europe. Where TRUE certifies a diversion outcome, MiZA certifies a structured journey, delivered in three phases:
Phase 1: On the Road to Zero Waste. Foundation criteria: a public zero waste commitment, a waste composition analysis, at least three months of tracked data, separate collection, a trained zero waste coordinator and a plan.
Phase 2: General criteria. Consistent across sectors, with three ambition levels. Crucially, the performance benchmark here is waste reduction, not diversion: total waste generation must fall by at least 30%, 40% or 50% from baseline depending on the level, alongside criteria on staff engagement, procurement, communication and innovation.
Phase 3: Sector-specific modules. Tailored criteria for sectors such as hospitality and restaurants, covering things like sustainable sourcing and eliminating bottled water.
Certified organisations are supported by MiZA-accredited mentors and auditors throughout; the certification doubles as a guided implementation programme.
The key differences at a glance
| TRUE | Zero Waste Europe / MiZA | |
|---|---|---|
| Administered by | GBCI (global, US-origin) | Mission Zero Academy, powered by Zero Waste Europe |
| Scope | A physical facility/site | The business and its operations, with sector modules |
| Headline metric | 90% average diversion over 12 months | 30–50% waste reduction from baseline |
| Structure | 81 optional credits, four levels (Certified–Platinum) | Three phases, three ambition levels |
| Support model | Self-directed with documentation review and verification | Mentor-guided throughout |
| Best-known context | North America and global corporates; sits alongside LEED | Europe; SMEs, hospitality, municipal ecosystems |
The philosophical difference that matters most
The most important distinction isn't geographic; it's what each standard rewards. TRUE asks: how much of your waste avoids landfill and incineration?MiZA asks: how much less waste are you generating in the first place?
A facility could, in theory, hit 90% diversion while generating just as much material as before. MiZA's reduction-from-baseline approach puts prevention (the top of the zero waste hierarchy) at the centre. TRUE, meanwhile, offers something MiZA can't yet match: global recognition, a mature credit framework and instant credibility with investors and corporate real estate stakeholders familiar with the GBCI family.
So which should you choose?
As a rule of thumb: multinational portfolios, manufacturing sites and organisations reporting to US or global stakeholders tend to suit TRUE; European SMEs, hospitality businesses and organisations early in their zero waste journey often get more value from MiZA's mentored, phased model. Some ambitious organisations pursue both, using MiZA to build the reduction culture and TRUE to evidence diversion performance.
The honest answer, though, is that the right certification depends on your baseline data, your waste contracts and your stakeholders. That's exactly the groundwork we help organisations put in place.
