ISO Survey Results 2015

ISO Standards

A total of 1,519,952 ISO certificates was issued to organisations across the world by the 31st December 2015. This is a 3% increase from 2014 when a total of 1,476,504 ISO certificates was issued. 2015 also saw the revision and publication of ISO 14001:2015 and ISO 9001:2015. Both standards were revised to incorporate Annex SL’s High Level Structure (HLS), identical core text, definitions and common terms making integration with other standards easier as well as to keep pace with the modern world. Organisations currently certified to the older version(s) of ISO 14001 and/or ISO 9001 have a 3-year transition period (running until September 2018) during which they can become certified to the respective 2015 version(s). Both revised standards were published in the last half of 2015 and by the 31st December 4,190 organisations were certified to ISO 9001:2015 and 947 organisations were certified to ISO 14001:2015.

The global distribution of standards is as follows:

ISO Standard




Percentage Change

ISO 9001:2008 (Quality)





ISO 9001:2015


ISO 14001:2004 (Environment)





ISO 14001:2015


ISO 50001 (Energy)





ISO 27001 (Information Security)





ISO 22000 (Food Safety)





ISO 13485 (Medical Devices)





It is worth noting that the high growth in the number of certificates issued for ISO 50001 is likely to be related to the fact that obtaining and maintaining certification to the standards is one of the routes large organisations can use to comply with Article 8 of the European Union Energy Efficiency Directive (2012/27/EU) whose initial compliance deadline was December 2015. As the directive mandates a compliance deadline every four years (i.e. December 2019, December 2023, etc.) the number of certificates of ISO 50001 is expected to rise considerably in these years. ISO 50001 is also going through the revision process and the new version is due for release in January 2019.

The industry with the highest levels of ISO 9001 certification is the basic metal and fabricated metal product with 104,652 certificates in 2015, this represents 13% of the total number issued. Other industries with high levels of ISO 9001 certification can be found below in the image on the left.  Similarly, for ISO 14001 certification, the industry with the most worldwide certificates is the construction industry with 43,759 issued by the end of last year. Other industries with high levels of ISO 14001 certification can be found in the image below on the right.


Accreditation to ISO 50001 and ISO 27001 have enjoyed huge growth in the last year with 77% and 20% increases respectively.  A number of industries boast high levels of accreditation to ISO 50001 including food and beverages, rubber and plastic products and basic metal and fabricated metal products with 13%, 10% and 14% of the certificates respectively out of a total number issued. All other industries with high numbers of ISO 50001 certification can be seen in the image below on the left. Alternatively, but not surprisingly, the Information Technology sector boasts 61% of ISO 27001 certificates issued. Other industries with high volumes of ISO 27001 certification can be viewed on the image below on the right.


ISO Standard certification is going from strength to strength. We should expect these numbers to increase over the 12 months especially with the introduction of ISO 45001 late in 2017.
