A comprehensive assessment of biofuel policies in the BRIGS nations: Implementation, blending target and gaps

Biofuels share a meagre fraction in the total fuel consumption, and their usage is speculated to upsurge steadily in the years to come. One of the key drivers for the development of biofuel production industries and simultaneous dilution of biofuels in the energy market is the country's policy. Hence, this critical review focuses on the evolution of biofuel policies in the BRIGS (Brazil, Russia, India, China, and South Africa) nations and successful implementation of the policies by the respective countries. In detail, this paper provides legal framework and policies prompted the expansion of biofuel research and industries across the BRIGS nations. It extensively presents key laws, blending targets, current regulation, national action plan, government support mechanism (subsidies), output targets, and major hurdles and scope in biofuel policies of BRIGS nations for efficient penetration of biofuel to the energy market.
