Most European countries and Asian countries, including Indonesia, Malaysia, South Korea, Taiwan, Thailand and Vietnam, have implemented mandatory blending regulations to support the development of domestic biodiesel markets, reduce dependence on fossil fuels and reduce emissions of greenhouse gases and roadside pollutants. Mandatory blending requires diesel to be sold in a blend with biodiesel – typically in the range of 5 to 20 percent (B5-B20).

Hong Kong’s Climate Change Strategy and Action Agenda Consultation Document (September 2010) recommends the adoption of a B10 blend and highlights the potential for using waste cooking oils in producing biodiesel locally. However, as of today, no mandatory blending requirement has been introduced.

Hong Kong has the ability to mandate blending today. On the one hand, ASB has the capacity to fuel every diesel engine in Hong Kong with a B10 blend. On the other, the warranties of most major automobile and engine manufacturers already support the use of at least a B5 blend, and many support blends of up to B20 or B100. Please consult the OEM Statement Summary Chart of the National Biodiesel Board for a non-exhaustive list of selected supporting engine manufacturers.
