Nynas - ISO 50001 advisory services

The Carbon Trust supported Nynas in effectively implementing a best practice energy management system, that would allow the company to deliver cost savings and achieve certification to the international standard for energy management systems, ISO 50001.

Nynas is a manufacturer of speciality oils and bitumen, selling its products globally from 23 depots around the world. In the UK the company operates a refinery in Eastham, Cheshire as part of a joint venture, as well as having a supply terminal with blending facilities in Dundee.

As a sizeable energy user, in 2015 Nynas decided to work towards achieving certification to the international standard for energy management, ISO 50001, across its two UK operating sites. This would allow the company to implement best practice across its internal processes and drive continual improvement in energy performance. Having the certification would also allow the company to automatically comply with the UK government’s ESOS Regulations, requiring large organisations to demonstrate that they have identified their cost-effective energy saving opportunities.

Nynas has worked with the Carbon Trust since 2012 to measure and reduce its organisational carbon footprint, at the same time as improving operational energy management and taking advantage of cost saving opportunities. Because of the strong working relationship developed over many years, Nynas asked the Carbon Trust’s advisory team to provide consultancy advice and support on how to implement a robust energy management system that would allow them to achieve ISO 50001 certification.


Initially the Carbon Trust evaluated their existing approach to energy management and completed a gap analysis to see what additional steps would need to be taken before Nynas was able to achieve ISO 50001 certification, highlighting areas for improvement in the company’s existing approach to energy management.

At the same time energy audits were carried out to help identify a range of future projects that would help to improve the energy efficiency of the two sites. The Carbon Trust also provided detailed energy management training to around 80 per cent of the company’s staff.


All staff undertook a pre-training to establish awareness and understanding baselines from which performance would be tracked. The content of the training programme was tailored to provide maximum benefit to the personnel being trained, taking into account the differing responsibilities for different job roles, such as the operators of high energy equipment, management, technical staff and administrators.

The Carbon Trust’s recommendations were used to improve Nynas Bitumen’s approach to energy efficiency analysis and management. Key recommendations and outputs have been incorporated within the Nynas Management System (NMS), an ISO9001 certified quality system which is applicable across the Nynas Group.

Within Nynas Bitumen UK this overarching framework was then complemented with a specific Bitumen Business Energy and Carbon Management System, which was developed to monitor carbon emissions and drive continual improvement in energy performance.

Thanks to the Carbon Trust’s support Nynas was able to achieve ISO 50001 certification at the company’s operational sites in the UK. Following this success the business is considering similar energy efficiency improvement initiatives across all its operations.

Our work with the Carbon Trust has helped us to sharpen our focus on energy efficiency as a business. By implementing ISO 50001 we were able to comply with the UK government’s ESOS regulations, but more importantly we have strengthened our approach to energy management with a system that allows us to continuously improve our processes and find new cost savings.
