Taiwan’s government is increasingly using green purchasing as an effective instrument to control solid waste and to mitigate the environmental impacts of consumption. The latest government guidance in 2003 on green procurements for public services expects more than 60% of procurements to come from green products. Most developed countries such as Sweden, Japan,Germany, and the Netherlands have positively considered green purchasing as a legal regulation. In the UK, some legal regulations have been imposed on power generation firms to purchase environmentally friendly resources as raw materials so as to conform to the system of non-fossil fuel obligation. Japan itself has set up a time schedule in guiding firms to engage in green purchasing and expects to have fruitful results very soon.
