TCO‘99 RequirementsD–2 User’s GuideThere are also other characteristics of a computer, such as energyconsumption levels, that are important from the viewpoints of boththe work (internal) and natural (external) environments. Since allmethods of electricity generation have a negative effect on theenvironment (for example, acidic and climate-influencingemissions, radioactive waste), it is vital to save energy. Electronicsequipment in offices is often left running continuously and therebyconsumes a lot of energy.What does labelling involve?This product meets the requirements for the TCO’99 scheme whichprovides for international and environmental labelling of personalcomputers. The labelling scheme was developed as a joint effortby the TCO (The Swedish Confederation of ProfessionalEmployees), Svenska Naturskyddsforeningen (The Swedish Societyfor Nature Conservation) and Statens Energimyndighet (TheSwedish National Energy Administration).Approval requirements cover a wide range of issues: Environment,ergonomics, usability, emission of electric and magnetic fields,energy consumption and electrical and fire safety.The environmental demands impose restrictions on the presenceand use of heavy metals, brominated and chlorinated flameretardants, CFCs (freons) and chlorinated solvents, among otherthings. The product must be prepared for recycling and themanufacturer is obligated to have an environmental policy whichmust be adhered to in each country/region where the companyimplements its operational policy.The energy requirements include a demand that the computerand/or display, after a certain period of inactivity, shall reduceits power consumption to a lower level in one or more stages. Thelength of time to reactivate the computer shall be reasonable forthe user.Labelled products must meet strict environmental demands, forexample, in respect of the reduction of electric and magneticfields, physical and visual ergonomics and good usability.
