This study highlights the impacts of individual and socioeconomic attributes on commuting disparities across age groups. Housing prices emerged as the most significant factor explaining commuting distance, followed by the importance of achieving a suitable home-work balance for young people.

Methodologically, the study draws on a dataset consisting of interviews with urban practitioners, and policymakers, as well as an analysis of media representations. The debate related to urban space and street trading in Harare has been largely one-sided for many years, dominated by a top-down discourse of power that pathologizes, marginalizes and stigmatizes street traders as “agents of urban disorder, diseases and pollution”, “economic parasites” and “criminals”. The success of these hegemonic discourses has justified and legitimized regressive policies of displacement, eviction, and penalization, thereby undermining street traders' contributions to the urban economy and livelihoods. Ultimately, this study contributes to the growing body of research on street trading in Global South cities, shedding light on the power structures and ideological underpinnings within the urban discourse.

Several policies have been followed worldwide, including high energy taxes in European countries. However, simultaneously, many countries still suffer from energy poverty, and energy taxation only aggravates this problem. Considering this situation, this research proposes implementing green tax reform in European countries where energy tax revenues would be used to alleviate energy poverty. This article analyzes the situation of European Union Member States regarding some relevant variables such as energy tax revenues and energy poverty indicators (inability to keep the home adequately safe, low final energy consumption in households, arrears on utility bills, and electricity prices). The results show a significant variation in the total share required for energy bills, ranging from 5 % to 40 %. Countries with high energy tax revenues suffering from energy poverty are identified as potential candidates for the proposed reform. It was found that Bulgaria, Cyprus, Greece, Italy, Portugal, Romania, and Slovakia are good candidates for reform. This situation is combined with an inefficient tax policy, resulting in a large amount of money being transferred for direct and indirect fossil fuels and environmentally harmful subsidies. An energy tax recycling scheme focused on reducing energy consumption using energy efficiency measures, for example, under a scheme of Public Energy Services, can be optimally combined to redistribute the energy tax income to reduce energy poverty and contribute to decarbonization if combined with a new scheme that removes harmful fossil fuel subsidies.</div></div>","PeriodicalId":48384,"journal":{"name":"Energy Research & Social Science","volume":null,"pages":null},"PeriodicalIF":6.9,"publicationDate":"2024-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142424924","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Malaysian government has signalled commitments to implement a targeted fuel subsidy reform where vulnerable households would be unaffected by the direct impact of higher fuel prices even after the reform.

This study employs a dynamic Computable General Equilibrium (CGE) model to examine the economic, social, and environmental impact of a targeted fuel subsidy removal in Malaysia under a spontaneous and gradual implementation scenario. The research also explores the impact of direct cash transfers to households and reinvestment in key sectors of the economy in the aftermath of the reform. Results from the study show that subsidy removal brings positive gains to the Malaysian economy in the medium to long term. Sequencing the phaseout of subsidies, providing compensation to vulnerable households, and reinvesting in education, health, transportation, and food assistance helps to avoid short-term adverse effects on households and output. The study recommends the need for a gradual removal of fuel subsidies that is accompanied by cash transfers to vulnerable households and investment in key sectors of the economy.</div></div>","PeriodicalId":11672,"journal":{"name":"Energy Policy","volume":null,"pages":null},"PeriodicalIF":9.3,"publicationDate":"2024-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142421098","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In urban and suburban contexts, road traffic is widely recognised as one of the primary sources of CO<sub>2</sub> emissions. Thus, to reduce environmental pollution, there is an urgent need to replace vehicles with more sustainable transport modes. In this regard, electric bikes and scooters are emerging rapidly, especially with the advent of the Coronavirus pandemic, leading to a significant redesign of cities. Moreover, the rapid development of bike lanes is reshaping contemporary urbanism following the evidence provided by recent studies, which proved that more considerable investment in bicycle infrastructure encourages bicycle travel. The recent pandemic and current energy crisis are prompting the demand for defining tools to improve the planning and design of bicycle infrastructure. Hence, it is essential to analyse the environmental and geometric-functional characteristics of the infrastructure to be implemented and its temporality (whether definitive or pop-up lanes). Above all, the perception of different groups of users should be considered to understand the possible attitudes related to the perception of safety, comfort, and sustainability. Therefore, this study demonstrates using the full consistency method (FUCOM) to detect the most suitable cycle lane alternative amongst the design models (5) for cycle lanes developed by a group of design field experts. The paper illustrates the findings from a pilot study in Palermo, Italy. The adopted results show that a separated lane was the most favoured type.
