Universal climate change has already had noticeable effects on the environment. Net damage costs of climate change are likely to be considerable and to swell over time and emissions from transportation sector and use of fossil fuels in this scenario is just like adding fuel to fire. This work is a small effort made not only to portray the development of future reliable technologies in eVehicle that provides a cleaner solution with less carbon footprint but also to explain and establish the importance of the eVehicle as the most efficient and clean means of transportation with the help of plan and performance analysis. This paper presents the detailed analysis of different components of Battery operated eVehicle. The proposed EV Design addresses issues like range, drive train efficiency, fast exploration of higher system voltages ,charging times and reduced vehicle weight and tries to develop it as an option that is significantly safe, energy efficient, environmentally-friendly and easily controllable and to do so design, analysis and MATLAB simulation is carried out on battery operated eVehicle. As a BEV has a complex structure for analysis a realistic model is considered the accuracy simulation results are verified with theoretical outcome.

Researchers, environmentalists, and policy makers are keen to reduce the dependency on use of fossil fuels towards climate change. Various alternatives are being implemented for alternate sources of energy for transportation sector; Biofuels can reduce the dependency on the import of the fossil fuels. Different kind of biofuels are available compositions are alcohols, ethers, esters etc. Commonly available biofuels are ethanol, methanol and biodiesel. They can be produced from various thermo-chemical and bio-chemical processes. Methanol has been gaining momentum as a potential alternative for traditional fossil fuels in transportation sector. There is an increased trend in the development of methanol as a fuel around the world. This paper deals with the study of the use of methanol as an automotive fuel. Methanol has certain positive properties on the vehicle’s performance. However, methanol cannot be used directly as a fuel in the vehicles due to volatility and compatibility issues. But it could be used as a blend with the gasoline for its characteristics such as high octane number and lower emissions. Blending of methanol with gasoline will have affect on the properties of blend, this paper discusses about the change in properties and its effects on engine.

The transportation sector of Senegal is dominated by the road subsector, which relies on fossil fuels: gasoline and diesel. Their combustion generates substances such as carbon dioxide, methane, nitrous oxide, and many others responsible for climate change, which has negative impacts on the environment, human health, and activities. This study is based on data collected from Senegal’s official reports on transport and energy, and Intergovernmental Panel on Climate Change (IPCC) greenhouse gases’ analysis methods. In the period 2000–2013, growing emissions were experienced, reaching up to 2.38 × 106 tCO2-eq in 2013. The aging vehicle fleet (~20 years old on average), made up of light-duty vehicles (around 85%), a fast-growing number of imported cars, and the predominance of diesel engines (around 59%) are the aggravating factors. Beyond climate change, other gaseous substances resulting from the combustion of fuels such as carbon monoxide (CO), sulfur oxide (SO2), and particle matters (PMs) contribute to the deterioration of the outdoor air quality. Therefore, it is becoming urgent to monitor the evolution of these emissions and take appropriate measures to reduce their concentrations in the atmosphere. The Government of Senegal has taken a step forward through the modernization of transport infrastructure, and the creation of a center dedicated to the monitoring of outdoor air quality (Centre de Gestion de la Qualité de l’Air—CGQA) and a center in charge of the technical control of vehicles (Centre de Contrôle Technique des Véhicules Automobiles—CCTVA) in Dakar, but much remains to be done.

Abstract. Pacific Islanders have been exposed to risks associated with climate change. Samoa, as one of the Pacific Islands, is prone to climatic hazards that will likely increase in the coming decades, affecting coastal communities and infrastructure around the islands. Climate models do not predict a reduction of such disaster events in the future in Samoa; indeed, most predict an increase. This paper identifies key infrastructure and their functions and status in order to provide an overall picture of relative vulnerability to climate-related stresses of such infrastructure on the island. By reviewing existing reports as well as holding a series of consultation meetings, a list of critical infrastructure was developed and shared with stakeholders for their consideration. An indicator-based vulnerability model (SIVM) was developed in collaboration with stakeholders to assess the vulnerability of selected infrastructure systems on the Samoan Islands. Damage costs were extracted from the Cyclone Evan recovery needs document. Additionally, data on criticality and capacity to repair damage were collected from stakeholders. Having stakeholder perspectives on these two issues was important because (a) criticality of a given infrastructure could be viewed differently among different stakeholders, and (b) stakeholders were the best available source (in this study) to estimate the capacity to repair non-physical damage to such infrastructure. Analysis of the results suggested a ranking of sectors from the most vulnerable to least vulnerable are: the transportation sector, the power sector, the water supply sector and the sewerage system.

Mitigation Policies

This study analyzes climate change mitigation policies focused on light-duty electric vehicles (LDEVs) in the transportation sector in Rio de Janeiro state, Brazil, in the 2016–2050 period. We use the Open Source Energy Modeling System (OSeMOSYS) to analyze scenarios that consider greater uptake of LDEVs in different time frames, implementation of a CO2 emission restriction policy, exclusion of fossil fuels from the power mix, and a combination of these policies. We find that carbon pricing, along with higher rates of LDEVs adoption, causes the highest emission reductions (up to 47%), albeit at higher costs. LDEVs become the preferred vehicle technology as soon as they reach cost parity with internal combustion engine vehicles in different scenarios. Greater LDEVs uptake, however, leads to increased electricity consumption (up to 3%), which is provided by fossil fuels when there is no emission restriction policy. If restrictions are placed on the expansion of fossil fuel power plants, fewer LDEVs are adopted (up to less than 26%) because there is not enough electricity to supply the demand. Given the state’s power mix in 2016 (58% provided by fossil fuels), investment in zero-carbon energy is necessary for mitigation policies in the transportation sector to be effective.

The objective is to examine the potential synergies between international environmental law and human rights when it comes to the protection of natural resources. To do so, it concentrates on three main areas of potential convergence. It first focuses on the pollution of natural resources and analyses how human rights law offers a potential platform to seek remedies for the victims of pollution. It next concentrates on the conservation of natural resources, particularly on the interconnection between protected areas, biodiversity, and human rights law. Finally, it examines the relationship between climate change and human rights law, focusing on the role that human rights law can play in the development of the current climate change adaptation and mitigation frameworks.

Smart Regulation

Increasing focus on sustainable societies and ‘smart cities’ due to emphasis on mitigation of climate change is simultaneous with ‘smart regulation’ reaching the forefront of the political agenda. Consequently, the energy sector and its regulation are undergoing significant innovation and change. Energy innovations include transition from fossil fuels to more renewable energy sources and application of new computer technology, interactively matching production with consumer demand. Smart cities are growing and projects are being initiated for development of urban areas and energy systems. Analysis from ‘Smart Cities Accelerator’, developed under the EU Interreg funding programme that includes Climate-KIC,——provides background for the focus on a smart energy system. Analysis ensures the energy supply systems support the integration of renewables with the need for new technologies and investments. ‘Smart’ is trendy, but when becoming ‘smart’ leads to motivation that is an important step towards mitigating climate change.

Design communities in engineering and other disciplines have a practical reason for caring about group creativity. People employed in these areas have to generate creative solutions routinely, and they often must do so in a group. As a result, research in these areas has focused on processes to improve group creativity. This chapter explores techniques for generating problem statements and solutions in groups that have emerged from this literature. It also examines computer-based methods of problem solving that groups can use to enhance the ideas that arise from these group processes. This work has expanded the range of elements explored in studies of group creativity. Although theoretical studies of creativity can be useful in uncovering underlying mental processes, design development requires useful end products. The focus of this research on techniques that enhance creativity in design provides an opportunity to link this literature with the broader literature on individual and group creativity.
