ABSTRACT
This research aims to analyze the political trajectory of biogas in Brazil according to the Multi -Level Perspective (MLP). Political trajectory is understood as the set of political events that constitute the path taken by a given transition towards sustainability. Politics, in turn, is understood as a regime dimension that is influenced by pressures from both the landscape and the socio-technical niche. In this context, policy can be used to create barriers to innovations and maintain the dominant position of regime actors, or it can facilitate their advancement. Therefore, this research is classified as documentary research focusing on the National Biofuels Policy (RenovaBio) enacted in 2017. Its realization involved documentary research in several national and international institutions. The main results point to a policy built on mandatory targets, Decarbonization Credits (CBIOs), and biofuel certification. Thereafter, the regulation of RenovaBio, the pandemic of COVID-19 and the taxation of CBIOs emerge as major developments. It is concluded that RenovaBio emerges as a response to the Paris Agreement that provoked the adaptation of the socio-technical system of fossil fuels in Brazil.
