Lastly, I would like to cover another area which I feel can be promoted more aggressively to drive energy conservation practices, which is, having an integrated system of financial incentives and disincentives. A comprehensive energy conservation policy, especially for a liberalised energy market such as in Singapore, should include such a financial system to support volunteer agreements with corporations on energy efficiency targets. In terms of financial systems, the developed world can be divided into three zones: EU and UK, AAC (America, Australia, Canada) and Asia, namely, Japan, Korea and Singapore. AAC offers both financial assistance to promote energy management and tax incentives to encourage achievement of energy efficiency targets. EU and UK use carbon emission market "cap and trade" to promote energy efficiency, but individual countries use a variety of other instruments, including financial assistance, tax incentives and green taxation. Asian countries, including Singapore, use only financial assistance.
