The promotion of biodiesel and bioethanol are expected to lessen by 3.0% the GHG emissions of the BAU scenario in 2012 and will decline dramatically after 2022 because of future biofuels supply limitation in the face of continuing increase in the demand for conventional fossil fuel in road transport.
By 2030, the annual GHG emissions reduction by the fuel switching mitigation option will decline to about 3751 kt of CO2-eq, accounting for 1.8% reduction from the BAU scenario.
