Were Guideline (optional), now Imperative (mandatory)

New Criteria

Green Key — the world's leading eco-label for hotels — has significantly updated its certification requirements for 2026–2031. The rules have been reorganised from thirteen topics into seven, with higher standards, new requirements around social responsibility and human rights, and a stronger focus on proving results rather than just having policies on paper. Effective 1 October 2026.

What is Green Key?

Green Key is the world's largest eco-label for tourism and hospitality, managed by the Foundation for Environmental Education (FEE). It's awarded to hotels, hostels, campsites, and other accommodation providers that meet a detailed set of environmental and social responsibility standards.

To earn the Green Key label, a property must pass an independent audit showing it meets these "criteria" — essentially a checklist of requirements covering everything from water and energy use to waste management, biodiversity, and fair employment practices. Properties are re-assessed periodically to keep their certification.

This guide explains what changed between the current criteria (2022–2025) and the new criteria (2026–2031). If your property holds or is seeking Green Key certification, this is your roadmap to understanding the new rules.

Key Terms

Before diving into the changes, here are the key terms you'll see throughout this guide:

Imperative (I)

A mandatory requirement — every property must meet this to earn or keep the Green Key label. In Green Key language, these are called "Imperative" criteria.

Guideline (G)

A recommended best practice — properties are encouraged to meet these, but they are not Imperative (mandatory) — yet. In Green Key language, these are called "Guideline" criteria.

G → I

G → I Upgrade

A requirement that was previously a Guideline (optional) but has been upgraded to Imperative (mandatory). Properties must now comply with something they could previously skip.

I → G

I → G Downgrade

The reverse: a requirement that was Imperative (mandatory) but has been downgraded to Guideline (optional). This is rare.

📋

Criterion / Criteria

A single rule or requirement (criterion) that properties are assessed against. Multiple rules = criteria.

🏨

Hotels & Hostels (HH)

The Green Key category for hotels and hostels. Green Key also certifies other types of properties.

🏢

Apartments (A)

Serviced apartments and holiday apartments.

⛺

Campsites (C)

Camping and caravan sites.

🏡

Rural / Attractions

Country houses, B&Bs, conference centres, and tourist attractions.

📅

Certification Period

The time window a Green Key certificate covers. Changed from annual to biennial (every 2 years) in the new criteria.

Executive Overview

The new criteria bring six major shifts in how Green Key evaluates properties. Here's a plain-language summary of what changed and why it matters for you.

Outcome-Based Measurement

Instead of simply having a written sustainability policy, properties must now set specific, measurable targets — like 'reduce water use by 15%' or 'cut food waste by 25%'. Small properties (≤50 staff) need at least 2 targets; larger ones (>50 staff) need at least 4.

Stricter Thresholds

Minimum standards are going up across the board. For example: 80% of showerheads and taps must be water-efficient (up from 75%), 80% of light bulbs must be LED (up from 75%), and 100% of rooms must be non-smoking (up from 75%).

Human Rights & Social Responsibility

For the first time, Green Key includes requirements around human rights and social responsibility — including a formal complaints/whistleblower mechanism, respect for Indigenous Peoples' rights, accessible facilities for people with disabilities, and employment opportunities for vulnerable groups.

Biodiversity as Core Pillar

A new 'Living Environment' section makes biodiversity a central requirement. Properties must assess their impact on local wildlife and ecosystems, monitor changes annually, avoid harmful chemicals like glyphosate, and plant native species.

Sustainable Procurement Policy

Every property must create a Sustainable Procurement Policy governing all purchases — food, cleaning products, textiles, furniture, and IT equipment. This is an entirely new Imperative (mandatory) requirement that touches every department.

Size-Tiered Requirements

Requirements now scale based on property size. Larger properties (>50 employees) face higher minimums for sustainability targets and action plans. Biodiversity assessments require external experts for properties larger than 5 hectares.

Certification Process Changes

The 2026–2031 update doesn't just change what properties are assessed on — it changes how certification works. From the length of the certification cycle to how properties prove compliance, here are the key process and policy changes.

Certification Cycle

2022–2025

Cycle

Annual — renewed every year

Effective Period

1 January 2022 – 31 December 2025

Action Plan

Annual plan with minimum 3 action points

Policy Review

Sustainability policy reviewed every 3 years

2026–2031

Cycle

Biennial — renewed every 2 years

Effective Period

1 October 2026 – 31 December 2031

Action Plan

24-month plan covering full certification period

Target Review

Strategic sustainability targets assessed every 2 years

Guideline Criteria Escalation

Old Schedule (Annual Steps)

Year	Guideline % Required
1	0%
2	5%
3	10%
4	15%
5–9	20%
10+	50%

New Schedule (Biennial Periods)

Period	Years	Guideline % Required
First	1–2	0%
Second	3–4	10%
Third	5–6	20%
Fourth	7–8	30%
Fifth	9–10	40%
Sixth+	11–12+	50%

The escalation is now steeper in the mid-range. Under the old system, properties could sit at 20% for five consecutive years (years 5–9). Under the new system, the percentage increases every 2 years: 10% → 20% → 30% → 40%, pushing properties toward more Guidelines sooner. Both systems cap at 50%.

How Properties Are Assessed

Was General written policy reviewed every 3 years

Now Measurable, data-grounded targets

Minimum 2 targets (≤50 staff) or 4 targets (>50 staff). Must define baselines and timelines. Assessed every 2 years.

Was Annual plan, minimum 3 action points

Now 24-month plan for full certification period

Minimum 2 actions (≤50 staff) or 4 actions (>50 staff). Each must link to a strategic target with documented timeline and responsible person.

Was Any staff member, no backup required

Now Permanent staff + named substitute

Both names shared with Green Key. Senior management explicitly responsible for certification.

Was Single physical or electronic binder

Now Evidence built into each criterion

Binder eliminated as standalone requirement. Structured audit methodologies (A/B/C) specified per criterion.

Was Administrative check of documents and policies

Now Visual inspections, interviews & sampling

Auditors use visual inspections, staff interviews, and sampling methodology (e.g., reviewing 3 employment contracts). Photographic evidence required. Documented justification plus concrete plan for next period when targets aren't met.

New Imperative Policy Requirements

These are entirely new standalone Imperative criteria that didn't exist before — they reflect Green Key's expanded focus on human rights, labour practices, and workplace safety.

Written contracts for all employees including subcontracted workers
Equal pay for equal work regardless of gender, ethnicity, or disability
Minimum living wage (ILO principles if no legal benchmark)
Auditors sample 3 employment contracts against payroll records

No employment of children under 14 under any circumstance
Strict protections for workers under 18 (written parental consent, regulated hours)
Compliance with UN Convention on the Rights of the Child and ILO Conventions 138 & 182
Protection from all forms of exploitation including sexual exploitation

Written grievance and whistleblower procedure
At least 1 confidential/anonymous reporting channel (e.g., FEE whistleblower platform)
Non-retaliation assurances
Guest reporting options in guest materials
Applies to establishments with >50 employees (smaller properties encouraged to have proportional options)

Written health and safety policies and emergency procedures
Must be reflected in day-to-day operations, not just documentation
Accessible and clearly communicated to all staff

Expanded Scope

The new criteria are now unified across 6 property categories — Hotels & Hostels, Campsites & Holiday Parks, Small Accommodations, Conference Centres, Restaurants/Cafés, and Attractions — with property-type applicability noted per criterion. Previously, separate documents existed for each category.

§1 Sustainable Management

24 criteria · 8 new · 3 removed · 9 high-impact · 1 merged in

This section is the heart of Green Key's management requirements. In the old criteria, management topics were spread across four separate sections (Environmental Management, Staff Involvement, Corporate Social Responsibility, and Green Activities). Now they're combined into one unified section. The biggest change is a shift from having a general 'sustainability policy' document to setting specific, measurable targets — such as reducing energy use by 10% or cutting food waste by 20%. Properties must also appoint a dedicated Green Key representative (with a named backup), set up a formal way to report concerns (a grievance mechanism), and take new responsibilities around human rights, accessibility, and community engagement. Many items that were previously Guidelines (optional) are now Imperative (mandatory).

Your Action Checklist

Effective Date: 1 October 2026

All new criteria take effect for the 2026–2031 certification period. Start preparing now to ensure a smooth transition.

Appoint Representative

Designate a specific person as your Green Key representative — someone on permanent staff who will oversee all certification matters. You also need to name a backup person in case they're away. The old title 'Environmental Manager' no longer applies.

Set Measurable Targets

Write down specific, measurable goals for improving your property's sustainability. For example: 'reduce water consumption by 15% by 2028'. Small properties need at least 2 targets; larger properties need at least 4. These replace the old general sustainability policy.

Implement Grievance Mechanisms

Set up a formal way for anyone — staff, guests, or community members — to report concerns about your property's practices. This could be an anonymous email address, a suggestion box, or a dedicated phone line.

Audit Fixtures & Systems

Check that at least 80% of your showerheads, taps, and light bulbs meet the new efficiency standards. Make sure heating/cooling switches off automatically in ALL rooms when windows are opened, and that ALL public area lights have motion sensors.

Create Procurement Policy

Write a policy that sets sustainability standards for everything your property buys — from food and cleaning products to bed linen and office supplies. This is a new Imperative (mandatory) requirement that affects every department.

Add Vegan Menu Options

Update your menu to include at least one vegan main dish or starter. Aim for 30% of all dishes being vegetarian. If your property serves food, this is now Imperative (mandatory).

Assess Biodiversity

Survey the wildlife and natural habitats around your property. If you have green areas, plan at least 2 biodiversity actions (like planting native species or installing bird boxes). Urban properties need at least 1 action.

Conduct Gap Analysis

Go through the new criteria line by line and check where your property already complies and where there are gaps. Make a prioritised plan to close those gaps before October 2026.
