Our planet's climate has experienced changes mainly ascribed to the emission of carbon dioxide (CO 2 ), which accumulates in the atmosphere and causes an increase in the Earth's average temperature. In 2015, heads of state and scientists from several countries met in Paris to discuss measures aimed at curbing greenhouse gas emissions in order to limit that temperature rise to 2°C by the end of this century. As CO 2 needs to be banned from our environment for the sake of our own planet, it is reasonable for biofuels to present themselves as clean alternatives for the gradual replacement of fossil fuels. Biodiesel stands as an option. After 2005, some public policies were created in Brazil as an attempt to establish biodiesel as a replacement for mineral diesel, mainly in the transport sector. Although moderately successful, none of them compare in scope and reach to RenovaBio, a domestic biofuels policy that will make the production and use of biodiesel take off, once and for all. Therefore, herein, we present a brief overview on the status of the biodiesel production and use before the enactment of this new biofuels policy and the forecast of what it is expected to happen after its implementation.Keywords: RenovaBio, biodiesel policy, fossil fuel, GHG, carbon dioxide, CO 2 emission three main heat-trapping gases (methane, nitrous oxide, and CFCs-except for CFC-13 and CFC-115), it is seen as the chief culprit of global warming, which has worried the scientific community around the world in recent years.Bearing in mind that it is essential to limit CO 2 emissions in the air, dozens of heads of state and hundreds of scientists from all over the globe gathered at the end of 2015, in Paris, for the 21st Conference of Parts-also known as COP21 or Paris Agreement-with the main goal of engaging nations in an international agreement on climate change in which everyone pledged to collaborate so that the increase in the average temperature of our planet should not exceed the limit of 2°C by the end of this century.At the COP21, Brazil voluntarily committed to: (1) cut down on GHG emission up to 37% by 2025 and 43% by 2030-considering 2005 as the base year for both scenarios [2]-which would represent approximately 1.2 million tons of carbon dioxide equivalent (CO 2 eq) by the year 2020 [3]; (2) increase the use of biofuels from sustainable bioenergy up to 18% of the total domestic energy mix by the year 2030 [4]; and (3) increase the share of renewables to an estimated 45% by the same year [5].So, considering the scenario wherein CO 2 needs to be banned from our environment for the sake of our own planet, it is reasonable for biofuels to present themselves as clean and renewable alternatives [6] for the gradual replacement of fossil fuels such as gasoline and mineral diesel, for example. Therefore, because biodiesel is biodegradable, less toxic, and almost 100% renewable [7,8], it stands as an option.After 2005, some public policies were created in Brazil as an attempt to definitely establish biodiesel as replacement for fos...
