It can therefore be advantageous to have an inte- grated management system for safety, health and the environment, plus Policy energy and quality. The diagram shows our management system with the elements of our everyday activities that are planned, managed and Management review Legislation and other requirements SHM reporting Aspects/risks/ followed up. The management system is constantly being developed in energy surveys order to better achieve our goal of reducing our environmental impact Internal audit Action plan including energy use and improving safety and the work environment, Noncompliance Objectives and as well as the quality for our customers using our waste incineration objective programme Monitoring and services. measurement Organisation Our integrated management system is certified in accordance with Documentation Training and skills environ mental management standard ISO 14001 and registered in Safety and protection Communications accordance with EMAS. This means that the environmental report is Operations audited by an independent environmental auditor. The system is also Operation and maintenance Purchasing health & safety certified according to OHSAS 18001, which is the Contractors Chemicals international standard for work environment. We were the first power company in Sweden with an energy management system certified according to ISO 50001. The quality system for waste incineration is ISO 9001 certified. Environmental auditor Intertek is one of SWEDAC’s accredited environmental auditors under EMAS (No. 1639). Vattenfall Heat Uppsala’s environmental management system complies with ISO 14001. Intertek has audited the environmental sections of the report and found them to be accurate and suffi ciently detailed to meet the requirements in EMAS. EMAS registration number SE-000224. The registration includes the plants in Uppsala: the combined heat and power (CHP) plant, waste incineration, Bolandsverket, the gas turbine, Husbyborgsverket, Stallängsverket, the refrigerating plants in Ultuna and Ångström, and the distribution network, plus the Knivsta and Storvreta plants and distribution networks. 2 Vattenfall Heat Uppsala Safety, Health and Environment 2014 2014 – a warm year with low emissions As everybody knows, the year was a warm In order to improve the security of supply and reduce our one and there was low demand for heat. heat losses, we also took signifi cant steps to reinvest During warm years, electricity generation in the existing network.
