Increased importance of climate change in management system Standards  

The International Organisation for Standardisation (ISO) and the International Accreditation Forum (IAF) have reinforced the importance of climate change for management systems.  

Two corresponding additions to a series of existing standards and in all new standards or standards under development/revision were made. As a result, standards users must consider the impact of climate change on the ability of their management systems to achieve the intended results. 

Details can be found in our implementation rules.

On the occasion of the amendment to the standards, we also developed the webinar "Climate change adaptation strategies, reference standards, methods and tools". It provides you with in-depth information on the additional requirements and shows you the potential of ISO management systems for a corporate approach to climate change and other sustainability issues.

New standard SN EN ISO 45001:2023: No need for action for holders of an SQS certificate  

The SN EN ISO 45001:2023 standard has been in place since 2023. It replaces SN ISO 45001:2018. The differences between the two standards are only of editorial nature. They have been adopted by the European Committee for Standardisation (CEN) and incorporated into a new Swiss standard by the Swiss Association for Standardisation (SNV) for the purpose of compatibility.  

Due to the editorial changes, various accreditation bodies in Europe have adopted guidelines regarding their country-specific standard. This means that there is a need for action by the certification bodies and holders of the old certificates in these countries. 

The Swiss Accreditation Service (SAS), on the other hand, is refraining from introducing new requirements. This means that neither the SQS as a certification body nor holders of ISO 45001:2018 certificates accredited in Switzerland need to take any action. 

Why exactly this is the case and what editorial changes SN EN ISO 45001:2023 contains can be found in our information document.

You want to improve?
Here are the 4 success factors.

#1 - Implement quality comprehensively 

What characterises a successful company?
In the foreground, of course, are high-quality products and services. But today, these alone are no longer enough to survive in the market. The quality and thus the long-term competitiveness of a company is also determined by numerous other factors. These include, among others

  • the management system,
  • cost control and optimisation,
  • risk management,
  • a transparent and efficient process landscape
  • and the ability to constantly improve and renew.

#2 - A credible environmental management

Who is against environmental protection? Exactly, today everyone is committed to the responsible use of the world's resources. But do we act accordingly? How do we distinguish between lip service and serious commitment? There are proven solutions to ensure that protecting the environment is not a «nice to have» but an integral part of the corporate culture and processes.

#3 - Occupational safety and healthy employees

Whether it's a small company or an international organisation - anyone who holds a managerial position bears responsibility for the health and safety of their employees. Higher and higher. Further. Faster. The pressure on employees is increasing in many companies and organisations. It is therefore all the more important to ensure and promote their safety and health. That is humanly correct. And it is in the interest of the employer. Because in our service society, employees are the ultimate success factor.

#4 - Understanding sustainability as future viability

«Sustainability» is not a fashionable topic. It is the requirement and the entrepreneurial opportunity of the 21st century. Companies whose business models contribute to climate change and endanger our ecosystems will sooner or later exit the market. Social requirements are also increasing. This means, for example, compatibility of work and family and the protection of human rights along the entire value chain. There are strategies and methods to respond to these changes in time and in the right way - so that you are on the winning side of the change.
