Abstract
Purpose
Current policies and research on carbon emissions focus on operational emission but overlook the importance of embodied and user-transport emissions in residential buildings. This study built a comprehensive framework to assess the impact of life-cycle carbon emissions on different in-building open public spaces (open roof, open vertical garden, and open ground floor) in affordable housing.
Design/methodology/approach
A parametric model of a typical affordable housing building in Shanghai, China was constructed and 36 variations of open public spaces studied. Embodied, operational, and user-transport carbon emissions were quantified over 50 years.
Findings
The results show that the life-cycle carbon emissions decrease with the application of the open public space. In addition, the paper found that the carbon reduction due to user transport is seven times higher than the carbon increment due to construction and over long-term operation.
Originality/value
This paper provides quantitative evidence for carbon emissions and in-building open public spaces, and the authors suggest taking multiple aspects into account in addition to the structure of the building is crucial to sustainable building development.

Abstract
Purpose
This paper sought to uncover the intrinsic determinants of the choice of transport modes in Nigeria's capital city, Abuja, based on commuters' perceptions on different modes of transport. The ultimate goal of the study was to come up with suitable multifaceted measures to deter private car usage, while refocusing society's mind-set towards alternative forms of transport, thereby keying into some transport-related sustainable development goals (SDG) goals.
Design/methodology/approach
The study adopted qualitative methods: 320 commuters were surveyed at bus stops and car parks around the city, and respondents were identified using multistage sampling, aided by purposive/convenience sampling, and this number was reached by saturation of themes. Focus group discussions were held with eight screened public officials from relevant (transportation and environment related) agencies/unions in the city. NVivo 10 software was used to thematically analyse the data gathered from a relativist and an interpretive stand point.
Findings
The study found transport mode choice to be intrinsically more motivated by socio-economic forces serving as a basis for other socio-psychological factors. Multifaceted measures, including spatial, socio-economic, environmental and public relation measures, were found suitable to break car-use motives in the study area towards adopting alternative modes of transport, thereby achieving some transport-related SDG targets.
Originality/value
The study was unique as it looked at the intrinsic mode choice determinants from a Sub-Saharan African capital city perspective and provided suitable multifaceted best practiced measures that deemphasised car use while emphasising alternative modes, thereby shifting commuters' mind-set towards environmentally sustainable modes of transport.

Abstract
Purpose
This research intends to investigate the determinants that affect consumers’ purchase intention of electric vehicles (EVs) in Malaysia using an extended theory of planned behaviour (TPB).
Design/methodology/approach
Survey data were collected with a sample size of 306. The research used SmartPLS 4.0 structural equation modelling tool to analyse the data. Reliability and validity tests (discriminant and convergent validity) were used and subsequently assessed the measurement and structural models. Mediation analysis was conducted to identify the role of the latent constructs.
Findings
The findings indicated that a green purchase attitude plays a complete mediation role in the effect of environmental knowledge on the purchase intention of EVs. In the same notion, the effect of price perception and availability of charging facilities on the purchase intention of EVs passes completely through perceived behavioural control. However, the subjective norm was an insignificant mediator of the impact between government support and EV purchase intention.
Research limitations/implications
This paper helps to examine the latent constructs that impact purchase intention using environmental knowledge, government support, price perception and the availability of charging facilities. Successful green marketing and a sustainable consumerism framework are seen as a booster to promote the usage of EVs in Malaysia.
Originality/value
An extended TPB model has been employed in this research to study the effects of the above-mentioned constructs. The results show that most of the extended constructs are significant in explaining the purchase intention. The empirical results address the gap in the consumer green attitude and provide insight into this area of study.

Abstract
Purpose
The purpose of this paper is to contribute to the understanding of social sustainable consumption in the context of improved ridership in public bus transport (PBT). It investigated the social predictors and implementation intention of drivers to use PBT.
Design/methodology/approach
The empirical data were collected through online survey. The respondents of the online survey were 313 drivers in Penang, Malaysia. A conceptual model was designed to test implementation intention of the drivers in using the PBT. Data analysis was performed using the variance-based structural equation modeling technique of partial least squares.
Findings
The findings indicate that the drivers’ intention to use PBT is significantly influenced by their referent group, gender role, and commitment to environment. In addition, their implementation intention is significantly predicted by the intention to use PBT.
Research limitations/implications
This study was performed in Penang using convenience sampling method. The results need to be replicated using a different sample in other developing countries to test its stability.
Practical implications
Policy makers and transport managers need to be guided by the importance of the drivers’ referent group, gender role, commitment to environment, and intention in order to improve ridership of the PBT.
Originality/value
The research on referent group, gender role, commitment to environment, intention, and the implementation intention of the drivers using the theory of interpersonal behavior in PBT is unprecedented.
