- Creation of social, economical, and environmental value added by security of sustainable alternative energy resources
Many countries are formulating policies for the implementation and use of renewable energy sources to counter the environmental issues such as global warming. Moving forward, global energy use will be greatly affected by environmental issues and the world's reaction to those issues. The common solutions to the global environmental issues include the use of alternative energy sources, namely renewable bioenergy. Bioenergy produced from biomass, such as vegetation, is one source of renewable energy that can significantly help lower carbon dioxide emissions, which are caused largely by use of fossil fuels (e.g., crude oil). Bioenergy is also more economical than crude oil as world crude oil prices are expected to remain high for quite some time. Therefore, environmentally friendly and economic aspects of bioenergy make it highly attractive, in turn increasing its demand drastically. This is a trend that is expected to continue and intensify into the long-term. In order to implement the issues regarding the global environmental issues, the European Union has decided to propose to its 27 Member States the commitment of the use of 10% of biofuels by 2020. Member States must set national indicative targets taking the reference values into account. In Korea, the government presented '2030 Energy Vision' for the use of 9% of environmentally friendly renewable energy. In order to stoke up the use of biodiesel, existing 'Petroleum Business Law' was amended as 'Petroleum and Alternative Fuels Business Law' in October 2004.

According to the US Department of Energy (DOE), the most significant environmental advantage of the use of biodiesel is reduction of air-toxics and cancer-causing compounds. Biodiesel 100% can reduce 94% of cancer-causing compounds compared to diesel fuel. In addition, biodiesel can mitigate the emission of acid rain-causing compounds because biodiesel has no sulfur compounds. Furthermore, biodiesel is generally produced from vegetation so that carbon dioxide (CO2) concentration in the atmosphere can be controlled through natural carbon cycle. After all, 1 ton of biodiesel can reduce 2.2 tons of CO2. Therefore, use of biodiesel will overcome energy crisis as well as environmental pollution.
