ISO 14001:2026 was published April 15, 2026. ISO 9001:2026 is at FDIS stage and expected in October. ISO 14001 has a 3-year transition, certificates must transition by May 2029. ISO 9001’s transition period will be set later and may be shorter than 3 years.¹

How long does implementation take? 20-80 hours for most organisations, far less than many fear. The longest task (quality culture) requires 6-12 months to show a trend, so start there.

Key dates:

Now: Start gap analysis, begin quality culture work
Autumn 2026: ISO 9001:2026 published
2027-2029: Certification audits against new versions
May 2029: Last date for ISO 14001:2015 certificates

See our gap analysis guide for requirement details.

AmpliFlow and the transition

For existing AmpliFlow users, the transition will be smooth. Your processes and documentation are already in the system. Contact your consultant if you need help planning.

Timeline: from gap analysis to certification

Phase 1: Gap analysis and planning (2-4 weeks)

Allow 4-8 hours to review requirements and verify what you already do. The quality or environmental manager leads this. Changes are moderate, most organisations find they already meet large parts.

Phase 2: Climate analysis (2-4 weeks)

Climate analysis is formally new in ISO 2026, but the requirement has applied since Amendment 1 was published in 2024. If you already have climate in your context analysis, verify documentation is clear. This takes 2-4 hours.

Missing climate entirely? You need 6-12 hours for a climate SWOT covering physical risks (flooding, heat waves), transition risks (regulatory changes), and opportunities.

Phase 3: Quality culture (6-12 months)

This is the project’s critical path. Not because the effort is large, but because culture development takes time. The standard requires showing a trend, meaning at least two measurements 6 months apart. Start early.

Month 1: Identify expected quality behaviours per role. Design anonymous survey. Communicate initiative. (4-8 hours) Month 2: First measurement. Analyse gap between expected and actual behaviours. (2-4 hours) Month 3-6: Implement improvements based on findings. (Ongoing) Month 7-12: Follow-up measurement with same survey. (2-4 hours)

Phase 4: Supply chain risks (2-4 weeks)

Most organisations already have supplier assessments. Verify they cover quality, delivery reliability, and critical supplier risks. (4-8 hours)

No structured supplier assessment? 8-16 hours to map critical suppliers and create a simple risk assessment.

Phase 5: Biodiversity (2-4 weeks, ISO 14001)

Office and service companies: 2-4 hours
Manufacturing: 4-8 hours
Agriculture, construction, forestry: 8-16 hours

Phase 6: Policy updates (1-2 weeks)

Policies likely need minor adjustments. Quality policy: add quality culture. Environmental policy: add ecosystem protection. Total 2-4 hours.

Phase 7: Change management under ISO 14001 clause 8.1 (1-2 weeks)

Most organisations already have processes for this. Verify they cover environmental consequences. Total 2-4 hours.

Phase 8: Internal audit and management review (2-3 weeks)

Review adjusted areas: climate, culture, supply chain, biodiversity. With moderate changes, allow 4-8 hours extra beyond routine audit.

Recommended timelines

Scenario 1: Early start (recommended)

Total time: 12 months. Comfortable timeline for culture measurements, no stress.

Months 1-3: Gap analysis, start quality culture, verify climate
Months 4-6: Supplier risks, biodiversity
Months 7-9: Policy updates, change management
Months 10-12: Second culture measurement, internal audit, management review

Workload: 2-5 hours per month.

Scenario 2: Normal start

Total time: 9 months.

Months 1-3: Gap analysis, start quality culture, verify climate
Months 4-6: Supplier risks, biodiversity, policy updates
Months 7-9: Second culture measurement, internal audit, review

Workload: 4-8 hours per month.

Key success factors

Start with quality culture. It is the only task that requires time, because you need 6 months between measurements to show a trend. Everything else is verification.

Verify before creating new. Before building new processes, check what you already do. Most organisations already have climate in their context analysis and supplier assessments in place.

Communicate that changes are small. Many in the organisation may worry about “another big ISO revision.” ISO itself describes the transition as smooth. DNV confirms: less extensive than the 2015 transition.

Summary

The ISO 2026 transition is moderate. For most organisations it means 20-80 hours of verification and minor adjustments.

The only thing that takes time is quality culture, because you need to show a 6-month trend between measurements. Start there and do the rest when it fits.
