Alternative fuel vehicles (AFV) are a promising alternative to reduce greenhouse gas emissions in the transportation sector and ultimately, to contribute to a more sustainable society. Within the current commitments of the Brazilian Government to international agreements, in terms of emissions reductions by 2030, some new policies have been implemented, in order to incentivize the diffusion of AFV in the country. Yet, how will these policies contribute to the goal of increasing its fleet in the long-term, how long will it take and what are the differences (if any) among the policies, in terms of their effectiveness, are questions that remain unanswered. In this sense, the main aim of this paper is to investigate the impact of public policies in the long-term diffusion dynamics of AFV in Brazil. In order to do so, a system dynamics model is developed, based on the Generalized Bass Diffusion model, the Cobb-Douglas function and the learning curve theory. The model is used to test four different policies and some uncertainties related to: (i) the exemption of the import duty; (ii) the reduction of the motor vehicle property tax; (iii) the exemption of the tax on manufacturing goods; and (iv) a banning regulation for internal combustion engine vehicles in the long-term. The results highlight the importance of the current incentive policies but at the same time call for reinforcing efforts in order to increase the AFV fleet to significant values by 2030. Conversely, the banning regulation obtains a higher diffusion rate, but only achieves significant values by 2060. The paper concludes by showing the main contributions and policy implications of the effectiveness of the four policies studied as well as some suggestions for future work. [ABSTRACT FROM AUTHOR]

Tourism in conservation units is a special section in ecotourism that helps in the development of a sustainable site. The deductive method, doctrinal survey and documents in official sites, such as documents and reports directly or indirectly produced by organs of the public authorities, are employed to discuss the following question: Can concessions for the exploitation of tourism in conservation units be sustainable development vectors through the generation of income and employment of communities living in the area? Current paper analyzes the legal and economical overview of public policies for the development of tourism in conservation units in Brazil and demonstrate the capacity of this type of tourism to positively impact the economy. Law 13,668/2018 authorizes federal authorities to concede services, areas or establishments of conservation units to third parties through bidding. It is expected that such concessions, based on the new legal diploma, may boost the segment's public policies by environmental, social and economic benefits. Public administrators have to meet the challenge to produce income and, at the same time, the conservation of biodiversity. Although only a few agreements have been signed, at recent dates and for long-term duration, an analysis of the contracts evidences true compatibilization and positive results sought by the new juridical instrument.
