Upcoming ISO Legislation Changes In 2025: What You Need To Know
Staying compliant with ISO standards isn’t just about meeting certification requirements—it’s about keeping up with legislative changes that impact how organisations operate. This year, several key updates will affect businesses certified to ISO 14001, ISO 22301, ISO 27001 and ISO 45001.
In this article, we break down the most significant changes coming into effect, focusing on the latest amendments to greenhouse gas emissions trading and waste separation rules in England.
Key ISO-Related Legislative Updates
Greenhouse Gas Emissions Trading Scheme (ISO 14001)
A major update to the Greenhouse Gas Emissions Trading Scheme (Amendment) (No. 2) Order 2025 will take effect from 31st March 2025. This change impacts organisations operating under ISO 14001, particularly those managing carbon emissions. The key amendments include:
- Delayed Allocation Period: The start of the second allocation period for stationary installations is now postponed from 2026 to 2027.
- Standalone Year in 2026: The year 2026 will be treated as a separate allocation period, requiring organisations to calculate free allocation independently.
- Ultra-Small Emitters Classification: Businesses with low emissions, that started operations between 2nd January 2021 and 1st January 2024, can apply for Ultra-Small Emitter status—reducing their administrative burden.
This change provides flexibility for new businesses while ensuring a structured transition for those already operating within the UK Emissions Trading Scheme (UK ETS).
Separation of Waste (England) Regulations 2025 (ISO 14001)
The Separation of Waste (England) Regulations 2025, also taking effect from 31st March 2025, clarify the rules surrounding waste segregation for businesses. If your organisation is certified under ISO 14001 (Environmental Management):
- Mixed Recycling Flexibility: Plastic, glass, and metal waste can now be collected together in all cases—previously, this was only allowed under certain exceptions.
- Paper & Card Must Be Separated: Paper and card must still be collected separately from other recyclables unless an exception applies.
- Exemptions for Small Businesses: Businesses with fewer than 10 full-time employees are exempt from waste separation requirements until 31st March 2027.
This update provides clarity for waste collectors and small businesses while reinforcing the government’s push toward sustainable waste management.
How These Changes Impact ISO-Certified Businesses
For organisations maintaining ISO compliance, these legislative updates highlight the importance of staying informed and proactive. Businesses should:
- Review risk assessments to ensure new legislation is accounted for.
- Update environmental policies and procedures to reflect waste separation and emissions trading changes.
- Provide staff training on new compliance requirements.
- Monitor further legislative updates, especially leading up to April 2025.
Stay Ahead of Compliance
With new legislation shaping the way ISO standards are implemented, businesses must be prepared to adapt. Keeping up-to-date with these changes ensures that your organisation remains compliant, efficient, and ahead of industry shifts.
