Investigating the link between carbon dioxide emissions and transport-related social exclusion in rural Northern Ireland

Abstract

Carbon dioxide (CO 2 ) is considered the most harmful of the greenhouse gases. Despite policy efforts, transport is the only sector experiencing an increase in the level of CO 2 emissions and thereby possesses a major threat to sustainable development. In contrast, a reduced level of mobility has been associated with an increasing risk of being socially excluded. However, despite being the two key elements in transport policy, little effort has so far been made to investigate the links between CO 2 emissions and social exclusion. This research contributes to this gap by analysing data from 157 weekly activity-travel diaries collected in rural Northern Ireland. CO 2 emission levels were calculated using average speed models for different modes of transport. Regression analyses were then conducted to identify the socio-spatial patterns associated with these CO 2 emissions, mode choice behaviour, and patterns of participation in activities. This research found that despite emitting a higher level of CO 2 , groups in rural areas possess the risk of being socially excluded due to their higher levels of mobility.

Knowledge-based, smart and sustainable cities: a provocation for a conceptual framework

“…Smart and sustainable cities assessment models gain key importance as local governments make commitments to reduce CO2 emissions and need adequate instruments to measure their performance (Bourdic et al 2012;Kamruzzaman et al 2015). According to Egilmez et al (2015), CO2 emissions per capita and percentage of workers moving using public transportation and or non-motorised modes can significantly affect the sustainability performance of a city.…”

Measures of Transport-Related Social Exclusion: A Critical Review of the Literature

“…Traditionally, the measures of deprivation have attempted to identify and assess these attributes [39]. These are often referred to as different dimensions (or domains) of deprivation such as economic, social, political, personal, living space, mobility impairment, and geographical isolation [8,29,[40][41][42][43][44].…”

Planning, Development and Management of Sustainable Cities: A Commentary from the Guest Editors

“…Environmental externalities mainly generated from population increase, rapid urbanization, high private motor vehicle dependency, deregulated industrialization, and mass livestock production have placed serious concerns for the future of our wellbeing, and even our existence in the long run [1][2][3][4]. Realization of the fact that urgent measures must be taken to combat environmental externalities responsibly, effectively, and efficiently have resulted in the rediscovery of the need for more eco-friendly practices [5][6][7].…”
