Aggreko, the global leader in temporary power generation, temperature control and oil-free compressed air solutions, has been awarded re-certification in ISO 14001 and OHSAS 18001, validating the commitment by the organization to maintain the high levels of standards recognized by the certifying bodies. Each re-certification applies to every Aggreko service center in the United States and Canada.

Both certifications require a company to meet specific industry standards. Recognized worldwide, ISO 14001 confirms an organization is effectively managing and mitigating its impact on the environment. Aggreko's environmental management system is a continuous cycle of planning, implementation, review, and improvement of actions carried out to achieve stated business and environmental goals. Occupational Health and Safety Advisory Services (OHSAS) 18001 Certification verifies a company effectively provides a safe and healthy workplace. OHSAS re-certification aligns with Aggreko's internal Safety for Life initiative to safeguard the well-being of its employees and customers.

Achieving re-certification confirms that Aggreko has not only met initial review requirements, but is continuing to implement best practices and procedures to achieve overall service excellence for customers.

"Everything we do at Aggreko begins with a focus on protecting our customers and employees," said Terry Dressel, Vice President, National Operations, Aggreko North America. "This commitment helps to ensure that we consistently manage our environmental, health, and safety risks through comprehensive systems in compliance with ISO and OHSAS standards of excellence."

In 2012 we served customers in about 100 countries, and had revenues of approximately GBP 1.6bn (USD 2.5bn or Euros 2.0bn).

For more information, please visit the company website at www.aggreko.com

Aggreko provides power and temperature control solutions to customers who need them either very quickly, or for a short or indeterminate length of time. Examples would be the supply of power to an industrial site which needs to service its permanent power supply, supplying a whole city in times of power shortage, or providing a major sporting event with power and cooling systems. We serve our customers either through our 194 service centers, which we call the Local business, or globally through our Power Projects business.

In the Local business, which accounts for about half of our revenues, we hire our equipment to customers, who then operate it for themselves, although we retain responsibility for servicing and maintaining it. In the Power Projects business, which also accounts for about half of our revenues, we operate as a power producer. We install and operate power plants and we charge our customers both for providing the generating capacity, and for the electricity we produce. We design and manufacture equipment specifically for these requirements in our factory in Dumbarton, Scotland.

Recent customers include the London 2012 Olympic and Paralympic Games, the Vancouver 2010 Olympic Winter Games and the power utilities in over 50 countries including the UK, France, Angola, Kenya, Indonesia, Bangladesh, Venezuela, Chile, Brazil and the USA.

In 2012 we fulfilled almost 45,000 customers' assignments and 70% of those who responded to our research gave us a recommendation of 9 or 10 out of 10.
