ISO 14001 UK vs USA · Environmental Management Systems
By Diana Lynn, President and Principal ISO Consultant, MSI · Updated October 29, 2026
ISO 14001 UK vs USA is the comparison of one identical environmental management process running on two different sets of local inputs.
Picture two plants that make the same product under the same standard, run by managers who trained on the same clauses. One closes its year with every compliance obligation evaluated and every significant aspect under control. The other learns, nine months late, that a state regulator tightened a discharge limit and nobody updated the legal register.
The process was not the problem. The inputs were.
That is the honest answer to the ISO 14001 UK vs USA question EHS managers at exporting and multinational companies keep asking. The clauses do not change at the border. What feeds them does: the environmental aspects you identify, the priorities you assign, and above all the compliance obligations you must meet. After 28 years of ISO consulting, 200+ audits attended and 80+ certifications supported, this is the pattern MSI sees most often when a system crosses a border. Organizations copy the documents and forget to localize the inputs.
Direct Answer
ISO 14001 UK vs USA: the standard is identical in both countries. The UK adopts it as BS EN ISO 14001, but Clauses 4 to 10 read the same. What differs are the inputs: environmental aspects may match or differ sharply, significance and priorities shift with context, and compliance obligations are always different.
Key Takeaways
- In ISO 14001 UK vs USA terms, ISO 14001:2026 applies identically in both countries; only the national adoption label differs.
- Environmental aspects can match closely between two sites with the same operations, or differ sharply where climate, water availability, energy supply or waste infrastructure differ.
- Clause 6.1.2 lets each organization set its own significance criteria, so the same aspect can be significant at one site and minor at another.
- Compliance obligations under Clause 6.1.3 are always jurisdiction-specific: UK obligations vary by nation, and US obligations stack federal, state and local requirements.
- As of October 29, 2026, certificates to ISO 14001:2015 must transition to ISO 14001:2026 by April 30, 2029, in both countries.
ISO 14001 UK vs USA · The Short Answer
What Is the Real Difference in ISO 14001 UK vs USA Implementation?
Standardize. Localize. Verify.
The real difference in ISO 14001 UK vs USA implementation is not in the standard. ISO published ISO 14001:2026 on April 15, 2026, and that single text governs certification everywhere it is used. In the UK, BSI adopts it as BS EN ISO 14001. In the United States, organizations work from the ISO text itself. The requirements, the clause numbers and the word “shall” are the same on both sides of the Atlantic.
What changes is everything the standard asks you to determine for yourself. ISO 14001 is written as a process: determine your context, determine your interested parties, determine your aspects, determine your compliance obligations, then plan, operate, check and improve. Every one of those determinations draws on local reality. That is where a UK system and a US system part ways.
“Aspects lists may be similar or way different, and priorities may be different based on context. Regulatory requirements are definitely different. But the process is the same.”
— Diana Lynn, President and Principal ISO Consultant, MSI
That observation gives this comparison its structure. Three inputs vary, and one engine stays constant:
- Environmental aspects (Clause 6.1.2) — sometimes nearly identical, sometimes very different.
- Significance and priorities (Clauses 6.1.2 and 6.1.4) — shaped by local context, interested parties and exposure.
- Compliance obligations (Clause 6.1.3) — always different, because the law is different.
- The process (Clauses 4 to 10) — identical, whether the site is in Manchester or Atlanta.
If you are new to the standard itself, start with MSI’s essential guide to ISO 14001 certification, then come back here for the cross-border view.
ISO 14001 UK vs USA · The Constant
What Stays Identical in Both Countries?
Plan. Operate. Improve.
The plan-do-check-act engine of Clauses 4 to 10 stays identical in an ISO 14001 UK vs USA comparison. A UK manufacturer and a US manufacturer both determine context in Clause 4.1, set an environmental policy in Clause 5.2, plan actions in Clause 6, control operations in Clause 8, evaluate compliance in Clause 9.1.2, audit in Clause 9.2 and review in Clause 9.3. An auditor from either country would recognize the other’s system immediately.
The 2026 revision reinforced that shared engine. Clause 4.1 now states that the issues an organization determines shall include environmental conditions such as pollution levels, availability of natural resources, climate change, biodiversity and ecosystem health. Clause 6.3, planning of changes, was elevated to its own clause. Neither change depends on geography, and both apply the same way in London and Los Angeles.
Accuracy matters here, because many comparison articles blur requirements and suggestions. The table below separates what the standard requires from what it only notes, and from what MSI recommends for cross-border systems.
| Item | Clause | Status |
|---|---|---|
| Determine internal and external issues, including environmental conditions such as climate change, pollution levels and biodiversity | 4.1 | Requirement (“shall”) |
| Determine interested parties, their needs and expectations, and which become compliance obligations | 4.2 | Requirement |
| Other interested-party needs become compliance obligations when the organization decides to comply with them | 4.2, NOTE 2 | NOTE — no obligation created |
| Policy commitment to protect the environment, including prevention of pollution, and to meet compliance obligations | 5.2 c) and d) | Requirement |
| Climate change mitigation and adaptation as possible specific policy commitments | 5.2, NOTE | NOTE — for consideration only |
| Determine aspects with a life cycle perspective and use established criteria for significance | 6.1.2 | Requirement |
| Determine and have access to compliance obligations; keep them as documented information | 6.1.3 | Requirement |
| Examples of legal sources: permits, regulations, court and tribunal judgments | A.6.1.3 | Informative Annex A — no added requirement |
| Carry out changes to the system in a planned manner | 6.3 | Requirement (elevated to its own clause in 2026) |
| Determine how often compliance is evaluated, evaluate it and maintain knowledge of compliance status | 9.1.2 | Requirement |
| Keep a separate legal register for each country, and for each US state where you operate | — | MSI recommendation |
| Internally audit every requirement of the standard at least once a year | 9.2 | MSI recommendation, reflecting what registrars expect |
Direct Answer
ISO 14001 UK vs USA process: Clauses 4 to 10 run the same plan-do-check-act engine in both countries. Context, policy, planning, operational control, evaluation of compliance, internal audit and management review are identical requirements. Only the content each clause draws on, such as local laws and local environmental conditions, changes.
Because the engine is shared, procedures can be shared too. One set of EMS procedures can run a UK site and a US site, provided each procedure points to local inputs rather than hard-coding them. That is the design logic behind MSI’s ISO Procedure Templates & Guides: standard process, room for local content.
ISO 14001 UK vs USA · Input One: Aspects
Do Environmental Aspects Differ Between UK and US Sites?
Identify. Compare. Localize.
Environmental aspects can be nearly identical or very different in an ISO 14001 UK vs USA comparison, and the deciding factor is what the site does and where it sits. Clause 6.1.2 requires the organization to determine the aspects it can control and influence, with a life cycle perspective, under normal, abnormal and emergency conditions. Annex A.6.1.2 lists the familiar categories: emissions to air, releases to water and land, use of raw materials, energy and natural resources, energy emitted, waste and by-products, land use, and use of marine and coastal areas.
Where UK and US aspects converge
Two plants running the same process with the same equipment will share most of their aspect list. Solvent use generates the same air emissions in Birmingham, England and Birmingham, Alabama. A powder-coating line produces the same waste streams on both sides of the Atlantic. For these aspects, a shared aspect taxonomy saves real time, and MSI client experience suggests that multi-site organizations that start from a common taxonomy finish their aspect registers faster and argue less about wording.
Where UK and US aspects diverge
Divergence appears wherever local environmental conditions change the cause-and-effect relationship between an activity and its impact. Common examples include:
- Water availability. Water use at a site in a drought-stressed part of the American Southwest is a different aspect, in scale and consequence, from the same use at a site in Wales.
- Purchased energy. The carbon intensity of purchased electricity varies by US grid region and differs again for the Great Britain grid, so identical energy use can carry very different emissions impacts.
- Climate exposure. Hurricanes on the Gulf Coast, wildfire in California and river flooding in parts of the UK change both the emergency situations you must determine under Clause 6.1.2 and the external conditions you assess in Clause 4.1.
- Waste infrastructure and end of life. Recycling access in the US varies municipality by municipality, while UK packaging reforms are reshaping downstream recovery, which changes the influence aspects you can claim for products after sale.
- Transport. Longer US distribution distances by road can make logistics a larger aspect than it is for a compact UK supply chain.
- Biodiversity and land use. Proximity to protected habitats, whether a UK Site of Special Scientific Interest or US critical habitat, turns land use and noise into significant aspects.
MSI’s guide to ISO 14001 environmental aspects walks through determination in detail, and the life cycle perspective article explains how far upstream and downstream to look. For the 2026 language on external conditions, see ISO 14001 environmental conditions.
Direct Answer
ISO 14001 UK vs USA aspects: two sites running the same process will share most environmental aspects, such as air emissions and waste streams. Aspects diverge where local conditions differ: water stress, grid carbon intensity, climate hazards, waste infrastructure, transport distances and nearby protected habitats. Start from a shared aspect list, then localize it site by site.
ISO 14001 UK vs USA · Input Two: Priorities
Why Do Significance and Priorities Change With Context?
Weigh. Rank. Act.
Significance changes with context because ISO 14001 lets each organization set its own criteria. Clause 6.1.2 requires the organization to determine which aspects have or can have a significant environmental impact “by using established criteria,” and to keep those criteria as documented information. The standard does not prescribe the criteria. In practice, that is where the ISO 14001 UK vs USA difference becomes a difference in priorities.
Most organizations score aspects on some mix of severity, likelihood, scale, legal exposure and interested-party concern. Hold the method constant and change the location, and the results move:
- Water consumption may score low at a site with abundant supply and high at a site under drought restrictions, even with identical volumes.
- Noise may be minor at an industrial park and significant at a site that backs onto homes.
- Stormwater runoff may be routine in one location and significant where it drains to a sensitive watercourse or a permitted outfall.
- Greenhouse gas emissions may carry higher customer and procurement weight for a UK supplier bidding on public contracts than for a US supplier selling only to private buyers, or the reverse for a US company covered by California disclosure law.
Clause 6.1.4 adds another layer. When planning, the organization must determine risks and opportunities related to its aspects, compliance obligations and other issues, including the potential for external environmental conditions to affect the organization. A UK site facing flood risk and a US site facing wildfire risk will rank their risks differently, even when their aspect lists match.
Interested parties in Clause 4.2 shift priorities too. UK central government buyers, US state regulators, local communities, insurers and multinational customers expect different things. Clause 4.2 c) requires you to decide which of those needs become compliance obligations. That decision is local, and it should be documented. MSI’s article on environmental risk as business risk shows how to connect these priorities to the decisions leadership actually makes.
The MSI recommendation for ISO 14001 UK vs USA systems is simple: keep one significance method, allow documented site-level weighting for local legal and environmental context, and record the rationale. Auditors in either country can follow a consistent method with transparent local adjustments. They struggle with a different method at every site.
ISO 14001 UK vs USA · Input Three: Compliance Obligations
How Do Compliance Obligations Differ in ISO 14001 UK vs USA Systems?
Determine. Apply. Evaluate.
Compliance obligations always differ in an ISO 14001 UK vs USA comparison, because Clause 6.1.3 asks each organization to determine and have access to the obligations related to its own aspects and to determine how they apply. Annex A.6.1.3 explains that these include laws and regulations, permits, orders from regulatory agencies and judgments of courts, plus other requirements the organization has to or chooses to adopt, such as customer agreements. None of that content travels across a border.
The UK: one country, four regulators
In the UK, environmental regulation is largely devolved. The Environment Agency regulates in England, the Scottish Environment Protection Agency in Scotland, Natural Resources Wales in Wales and the Northern Ireland Environment Agency in Northern Ireland. A company with sites in England and Scotland already runs two regulatory relationships.
Core UK frameworks include the Environmental Permitting (England and Wales) Regulations 2016, the waste duty of care under section 34 of the Environmental Protection Act 1990, and the Environment Act 2021. Scotland and Northern Ireland run their own permitting regimes.
Two newer schemes reach well beyond heavy industry. Under packaging extended producer responsibility, a UK-established business that supplied or imported more than 25 tonnes of packaging and has turnover of £1 million or more is an obligated producer. Under the Energy Savings Opportunity Scheme, large undertakings with 250 or more employees, or turnover above £44 million and a balance sheet above £38 million, must notify compliance for Phase 4 by December 5, 2027.
The USA: federal, state and local layers
In the United States, the obligations stack. Federal statutes such as the Clean Air Act, Clean Water Act, Resource Conservation and Recovery Act, Emergency Planning and Community Right-to-Know Act and Toxic Substances Control Act are listed on the EPA’s laws and executive orders page. Many of these programs are delegated to states, which can and often do set stricter requirements. Local air districts and wastewater pretreatment permits add a third layer.
The practical consequence is that a company with plants in three states needs three legal registers, not one. A Georgia site and a California site may share a federal baseline and little else.
| Topic | United Kingdom | United States |
|---|---|---|
| Primary regulators | Environment Agency, SEPA, Natural Resources Wales, NIEA | US EPA plus state environmental agencies; local air and water authorities |
| Permitting | Environmental Permitting (England and Wales) Regulations 2016; separate regimes in Scotland and Northern Ireland | Federal permits (for example Clean Air Act Title V, Clean Water Act NPDES), largely administered by states |
| Waste | Duty of care, Environmental Protection Act 1990 s.34 | RCRA hazardous waste rules, with state programs and state-specific waste codes |
| Chemicals | UK REACH | TSCA, EPCRA reporting, state chemical rules |
| Energy and carbon | ESOS (Phase 4 notification by Dec 5, 2027); UK ETS for covered installations | Federal rules in flux; California SB 253 Scope 1 and 2 reporting for companies over $1 billion revenue |
| Packaging | Packaging EPR across the UK | State packaging EPR laws in a growing group of states, such as California, Colorado, Maine, Minnesota and Oregon |
| Public procurement | PPN 006: Carbon Reduction Plans for central government contracts above £5 million per year | Varies by agency and state; customer requirements dominate |
| Self-disclosure | Regulator-specific enforcement policies | EPA Audit Policy: penalty mitigation for systematic discovery and prompt disclosure |
Differences run deeper than statute names. Even the definition of what counts as environmental harm, or an environmental crime, varies from one country to the next. Diana Lynn has made that point in MSI’s coverage of the international environmental crime debate:
“This is a greater reason for International Standards on definitions and trusted science resources.”

Direct Answer
ISO 14001 UK vs USA compliance obligations: they are always different. UK obligations depend on which of four national regulators covers the site and include permitting, duty of care, packaging EPR and ESOS. US obligations stack federal statutes, state programs and local permits, so each state needs its own legal register.
Freshness Check · As of October 29, 2026
What Does the 2026 Regulatory Climate Mean on Each Side of the Atlantic?
Watch. Update. Prove.
In 2026 the two countries are moving in different directions, and an ISO 14001 UK vs USA system has to keep up with both. US federal environmental policy is in a period of rapid rollback and litigation. UK policy is moving steadily toward more climate, packaging and energy obligations. Both trends hit the same clauses: 4.1 context, 6.1.3 compliance obligations, 6.3 planning of changes and 9.1.2 evaluation of compliance.
United States: deregulation, states and courts
On February 12, 2026, the EPA finalized a rule rescinding the 2009 greenhouse gas endangerment finding, eliminating federal greenhouse gas standards for light-, medium- and heavy-duty vehicles, as the National Law Review reported. The EPA’s regulatory agenda published in July 2026 continues that deregulatory direction, according to Bloomberg Law.
Fewer federal rules do not mean a lighter environmental management system. Legal analysts at Steptoe note that environmental groups are preparing citizen lawsuits and that some states are strengthening their own enforcement programs. Obligations often shift to states rather than disappear.
California is the clearest example. Under SB 253, US companies doing business in California with more than $1 billion in annual revenue face a first Scope 1 and 2 reporting deadline of November 10, 2026, while enforcement of the companion SB 261 climate-risk law is stayed pending appeal, as summarized by Cooley.
US companies also have a tool UK companies do not: the EPA Audit Policy. It allows a 100% reduction in gravity-based penalties when all nine conditions are met, including systematic discovery through an environmental audit or compliance management system and written disclosure within 21 days. A well-run ISO 14001 system, with real internal audits and compliance evaluation, is the kind of systematic discovery the policy rewards.
United Kingdom: steady, additive change
UK change is less dramatic but more cumulative. Packaging EPR is now operating, ESOS Phase 4 is under way, and central government procurement under PPN 006 requires bidders on contracts above £5 million per year to publish a Carbon Reduction Plan committing to net zero by 2050 for UK operations. For a UK register, the trend is additions, not reversals.
What this means for an ISO 14001 UK vs USA EMS
A US register that only adds obligations will soon list rules that no longer exist. A UK register that only checks annually may miss new duties. Both need a working change process under Clause 6.3 and a compliance evaluation frequency, under Clause 9.1.2, that matches how fast the law is moving.
One subtlety catches many US teams. When a federal rule is rescinded, the legal requirement may disappear, but a customer contract, a corporate policy or a voluntary commitment may still require the same control. Annex A.6.1.3 treats those as compliance obligations once adopted. Before you remove a control, check every source that created it.
Diana Lynn’s view on that point is direct:
“If your environmental policy says you will not harm the environment or people, then knowingly exceeding what the science has proven harmful puts you in conflict with your own policy.”
— Diana Lynn, President and Principal ISO Consultant, MSI
MSI’s guide to regulatory change management explains how to build that watch into the system rather than leaving it to one person’s inbox.
ISO 14001 UK vs USA · Accreditation and Transition
Who Certifies an ISO 14001 UK vs USA System, and When Is the Deadline?
Accredit. Certify. Transition.
Certification works the same way in both countries, through accredited certification bodies. In the UK, the national accreditation body is UKAS. In the United States, a leading accreditation body for management system certification is ANAB. Both operate within the international recognition arrangements now run by Global ACI, which replaced IAF and ILAC on January 1, 2026. An accredited certificate issued in one country is recognized in the other.
UKAS set out its national milestones in a May 2026 technical bulletin: ISO 14001:2026 published April 15, 2026; UKAS ready to receive applications and begin transition assessments from May 4, 2026; and a first tranche of transition decisions for certification bodies by November 30, 2026. In the US, ANAB-accredited certification bodies are moving through the same process, and several have already announced accreditation to the 2026 edition.
The deadline is shared. As of October 29, 2026, certificates to ISO 14001:2015 must transition to ISO 14001:2026 by April 30, 2029, wherever the certificate was issued.
For organizations with an ISO 14001 UK vs USA footprint, the bigger decision is structure. Some certify each country separately; others use one certification body and a multi-site certificate covering both. MSI’s articles on multi-site ISO certification and multi-site ISO integration compare those routes. To see where your transition risk sits today, try the free ISO Transition Risk Scorecard.
To train your team on every change before transition, MSI’s ISO 14001:2026 Transition course works the same way for UK and US sites. Also review MSI’s guide to the ISO 2026 transition deadline.
Direct Answer
ISO 14001 UK vs USA certification: UK sites are typically certified by UKAS-accredited bodies and US sites by ANAB-accredited bodies, and both are recognized internationally through Global ACI. As of October 29, 2026, both countries share the same deadline: ISO 14001:2015 certificates must transition to ISO 14001:2026 by April 30, 2029.
ISO 14001 UK vs USA · Original MSI Asset
How Do You Run One EMS Across Both Countries?
Standardize. Localize. Verify.
You run one EMS across both countries by standardizing the process and localizing the inputs, then proving both work. MSI built the scorecard below for this article to help EHS managers test an ISO 14001 UK vs USA system before an auditor does. Score each line 0 (not in place), 1 (partly in place) or 2 (fully in place and evidenced).
| # | Check | Clause | Score 0–2 |
|---|---|---|---|
| 1 | One shared set of EMS procedures covers Clauses 4 to 10 for every site | 4.4 | |
| 2 | A separate legal register exists for each country, and for each US state where you operate | 6.1.3 | |
| 3 | A shared aspect taxonomy is used, with documented site-level additions | 6.1.2 | |
| 4 | Significance criteria are common, and any local weighting is documented with a rationale | 6.1.2 | |
| 5 | Each site’s context review covers local environmental conditions such as water, climate hazards and biodiversity | 4.1 | |
| 6 | Compliance evaluation frequency is set per jurisdiction, reflecting how fast its rules change | 9.1.2 | |
| 7 | Internal auditors are briefed on the local obligations of each site they audit | 9.2 | |
| 8 | Management review reports compliance status and changes in obligations by jurisdiction | 9.3 |
Decision rules: 13 to 16 points means the system is ready to operate across borders. 8 to 12 points means the process is sound but the inputs need localizing before the next audit cycle; start with checks 2 and 6. 0 to 7 points means the system is a copied document set; rebuild the inputs before relying on it.
The most common low score in MSI client experience with ISO 14001 UK vs USA expansions is check 2. Organizations that expand from the UK into the US, or the reverse, tend to translate the first register rather than build the second from the new jurisdiction’s laws. Translation finds the obvious federal or national items and misses state, local and permit-specific conditions.
Check 1 is where the most money is saved. In MSI consulting engagements, writing procedures averages about $12,000. A shared procedure set, written once with local inputs referenced rather than embedded, lets you pay that cost once. MSI’s ISO Procedure Templates & Guides were built for exactly that, and the ISO 14001:2026 Procedure Templates & Guides were built to help experienced EHS managers update an ISO 14001:2015 system to 2026 in a week’s time.
For teams that would rather hand the update off, the ISO 14001:2026 Procedure Update Service revises existing procedures to the 2026 edition. MSI’s integrated management system guide covers the same approach when ISO 9001 and ISO 14001 share one system.
ISO 14001 UK vs USA · Clauses 9.1.2, 9.2 and 9.3
What Should Internal Audits and Management Review Check?
Audit. Review. Decide.
Internal audits and management review are where an ISO 14001 UK vs USA system proves its inputs are local and current. Clause 9.1.2 requires the organization to determine how often compliance will be evaluated, evaluate it, take action if needed and maintain knowledge of its compliance status. Clause 9.2.2 requires the internal audit plan to consider the environmental importance of the processes concerned, changes affecting the organization and the results of previous audits. In a cross-border system, the changes include changes in law.
Diana Lynn’s position on audit frequency, formed over 200+ audits attended from the registrar’s side of the table, is plain:
“If you are not doing internal audits on an annual basis, you are not compliant.”
— Diana Lynn, President and Principal ISO Consultant, MSI
Registrars across the industry expect every requirement of the standard to be internally audited each year. For an ISO 14001 UK vs USA system, that means every site, every register and every significant aspect, checked against the law that applies there, not the law at headquarters.
Management review then turns those findings into decisions. Clause 9.3.2 requires inputs on changes in compliance obligations, changes in significant environmental aspects, and trends in meeting compliance obligations. Reporting those inputs by jurisdiction lets top management see at once whether the US register is keeping pace with state changes and whether the UK sites are ready for new duties.
MSI promotes management review as the best way to begin planning a transition. The quicker start is an “End in Mind” review: put the data you already have on the review slides and mark missing data as TBD with dates. MSI’s ISO 14001:2026 management review article explains the 2026 inputs, and the free 5 Steps to a Decision-Ready ISO Management Review guide gives the sequence.
Direct Answer
ISO 14001 UK vs USA audits and reviews: internal audits should test each site against the law that applies there, and every requirement should be audited at least once a year. Management review should report changes in compliance obligations, significant aspects and compliance trends by jurisdiction, so leaders see each country’s status.
Auditing across an ocean raises a practical question: who travels? How MSI travels affects climate change, and MSI is very considerate of the travel choices it makes.

Frequently Asked Questions
ISO 14001 UK vs USA: Frequently Asked Questions
Ask. Answer. Act.
Is ISO 14001 the same standard in the UK and the USA?
Yes. In an ISO 14001 UK vs USA comparison, the requirements are identical. The UK publishes the standard as BS EN ISO 14001, but the text of ISO 14001:2026, including Clauses 4 to 10, is the same in both countries. The differences lie in the aspects, priorities and compliance obligations each organization determines.
Can a UK company’s EMS be copied for a US site?
The process can be copied; the inputs cannot. Procedures for Clauses 4 to 10 can be shared, but the US site needs its own context review, its own aspect review with local conditions, and its own legal register built from federal, state and local requirements.
Does a UK ISO 14001 certificate count in the USA?
Yes, when it is issued by an accredited certification body. UKAS and ANAB both operate within the international recognition arrangements now run by Global ACI, so accredited certificates are recognized across borders. The certificate’s scope must still cover the US site for that site to be certified.
Does US deregulation reduce what an ISO 14001 system must do?
No. In the ISO 14001 UK vs USA picture for 2026, US federal rollbacks change the content of the legal register, not the requirements of the standard. States may strengthen their own rules, citizen suits may increase, and customer or voluntary commitments can keep a control in place after a federal rule is rescinded.
When must certified companies move to ISO 14001:2026?
As of October 29, 2026, certificates to ISO 14001:2015 must transition to ISO 14001:2026 by April 30, 2029, in both the UK and the USA. UKAS began accepting transition assessments from May 4, 2026.
Do I need a separate legal register for each US state?
MSI recommends it. ISO 14001 Clause 6.1.3 requires you to determine the compliance obligations that apply to your aspects, and state law often differs from federal law and from other states. A register per state, sharing a common federal baseline, keeps evaluation of compliance accurate.
