A few years before the 2002 presidential election, Luiz Inacio Lula da Silva’s wing in the Workers’ Party (PT) made a sharp shift to the right. During the elections he attracted a conservative alliance to support him in order to avoid losing its third election in a row (Arretche, 2013). Yet there were hopes that a postneoliberal era of environmental policies was coming. The choice of Marina Silva as environmental minister fed those hopes. Silva, born in the rubber-rich forests of Acre, was an iconic environmental militant who fought along with Chico Mendes against the deforestation of Amazonia. However, hopes faded away, as the conservative alliance that supported President Lula in Congress opposed any legislative innovation that could threaten their interests, particularly those of the rural caucus. Moreover, the Lula administration also represented the return of the national developmentalist state, whose project places a high value on increasing commodity exports. During the PT’s three terms in office, environmentalists have been facing a series of political setbacks. Congress approved the use of genetically modified organisms (GMOs), and revised the forest legislation to lift land-use restrictions; the Brazilian Institute of Environment and Renewable Natural Resources (IBAMA) licensed mega-dams in Amazonia in controversial processes, and the federal government sharply slowed down the creation of protected areas (PAs) and indigenous lands. However, news from the environmental front was not all bad during this period. Thanks to the Brazilian federalist system, state governments have a fair degree of autonomy, which can be used to pass and implement innovative policies. Traditionally, the states that have advanced further in environmental policies are those that are rich, whose economies are less dependent on natural resources, and who have stronger social movements and knowledge networks (Toni, 2006). States in Amazonia do not fall within this category. They are on the agricultural frontier and part of their political elite thrives on the free exploitation of natural resources. Traditional discourses in these states depict environmental policies as a burden that hinders economic growth and development at the state/ local level. Nevertheless, since the late 1990s, some states in Amazonia haveengaged in promoting biodiversity conservation and protecting the livelihoods of traditional populations that dwell in forests. In this chapter we analyze the trajectory of environmental policies in two Amazonian states: Acre and Amazonas. In both cases we identify a set of innovative environmental policies that marked the state administration and have endured for almost 16 years in Acre and 12 years in Amazonas. We call those polices innovative because they did not come gradually. Rather, they represented a rupture-at least partial-with a conventional development model. Moreover, they were only possible after electoral changes. In the case of Acre, change meant a new elite coming to power, whereas in Amazonas elections brought a change within the ruling elite. Nevertheless, the outcomes of this change were no less impressive than in Acre. Electoral and policy changes in Acre and Amazonas are discussed in parts two and three of this chapter. Before that, in the first part after this introduction, we briefly discuss the relation between the states and the federal government, and the role that each one can play in environmental policies. In the fourth part the chapter examines how the governors of Acre and Amazonas engaged in politics outside the state arena, specifically in negotiations to affect carbon policies in the federal and international arena and, after leaving office, as senators.
