Abstract

A major challenge for humankind is to reduce global carbon dioxide (CO2) emissions to avoid the most harmful impacts of climate change. The transport sector is responsible for almost 1/4 of the world's energy-related emissions, with road transportation representing around 1/5 of the fuel consumption. Electric vehicles (EVs) may help to reduce CO2 emissions, but their diffusion is uncertain due to market barriers. This paper investigates the electric vehicle (EV), which has a smaller ecological footprint, as an alternative capable of meeting the needs of personal transport in Brazil. To carry out this evaluation, the study considers socio-techno-economic and political-environmental-innovation aspects to assess the challenges and opportunities facing the adoption of electric vehicles. The analysis was carried out based on a survey administered to a wide range of stakeholders. A SWOT analysis was performed to understand the most critical factors affecting the future of EVs in Brazil, which is a top-ten automotive manufacturer worldwide and a leader in sugar cane ethanol production. The results suggest light-duty electric vehicles (LDEV) as a first option for low-carbon passengers' mobility and that EVs expansion will require market regulation, incentive policies and adequate charging infrastructure. Both consumers and society in general will benefit most from the expansion of EVs due to low emissions and total cost of ownership (TCO). The results show where decision-makers should focus their attention. [ABSTRACT FROM AUTHOR]

Abstract

The Brazilian cities as well as many of the large urban centers in the world continue to expand, increasing the demand for mobility and transport, while, at the same time, the same cities are investing in greenhouse gas (GHG) mitigation to avoid climate change. Brazil's urbanization rate increased from 26% in 1940 to almost 70% in 1980. During this period, the Brazilian population tripled and the urban population multiplied by seven. In 2010, the transport sector in São Paulo accounted for 71% of the total emissions released by the energy sector. Ethanol has been considered a fuel with less greenhouse gas emissions, when compared with fossil fuels. However, ethanol production would have to double to meet the expected demand. Electric vehicles (EVs) market is expanding around the world, and is also an option to reduce the transport emissions, if powered by clean electricity. To assess whether the adoption of EVs might bring more benefits than the current ethanol, we develop prospective scenarios supported by the Long-range Energy Alternatives Planning (LEAP) simulation tool, taking a bottom-up tank-to-wheel approach to consider the CO2emissions of car in São Paulo. The scenario considering a substitution of 25% of gasoline-powered cars by EV in 2030 showed a reduction in energy consumption and CO2emissions, around 15% and 26% respectively in that year in comparison with 2015. We discuss the interplay between ethanol and EV, also considering emission coefficients from life cycle analysis conducted in Brazil, and concluded EV will have higher positive impact on climate change mitigation than ethanol.

Abstract

Climate change determines the retreat of ice. This has created a huge access to petroleum, attracting strong interest by some states, especially energy hungry-countries and increasing competition between states, resulting in tension and threats, even military ones. Climate change has, therefore, to be perceived as a threat to international peace and security. However, recognition of the nexus between climate change, human security and conflicts in the prism of international law and politics is weak, leading to a difficulty institutions have for regulating and governing this nexus. Climate change can thus be considered as threat-multiplier, something that can exacerbate existing tensions, and the resolution of this threat will be the most difficult task to achieve where adaptation takes place in fragile and vulnerable areas, such as the Arctic, an area which is highly exposed to environmental risks and uncertainty. The region is populated by one of the most vulnerable groups, the indigenous people, such as the Inuit of the Arctic with low adaptive capacity compared to the pace of change. In the Arctic Environmental Ocean governance, access to natural resources, the potential of navigability, extension of maritime borders, and the desire of some states to extend their jurisdiction, all depict a situation of criss-crossing potential conflicts that could escalate and should, therefore, be perceived as “tinderboxes”. This article relatedly explores the existing legal framework in the case of the Arctic environmental ocean to provide effective and legitimate governance for a peaceful and “stable space” to prevent threats from both Arctic and non-Arctic states. It will be shown that Arctic Environmental Ocean activities need multi-level governance (global, regional, national and local) and that Arctic environmental security challenges cannot be addressed without a broader holistic vision. The article treat the United Nations regulatory level and how it could support many issues which have an impact on Arctic Environmental Ocean governance, and the Law on the Sea. Methodologically, the way to increase effectiveness to maintain and stabilize the Arctic environmental ocean governance entails that “stability” is achieved by integrating elements of climatology, international law, political science and agent based modelling to act in a preventative way to protect the Arctic environmental ocean and its societies and formulate effective policies. The conclusion led on how the current Arctic environmental ocean framework could be changed in order to increase effectiveness by incorporating risk analysis into a universal equation based model to redesign a new regulatory package at United Nations level and recommend changes at institutional level.
