This paper aims to develop a comprehensive conceptual framework of the customer value proposition of formic acid as an actual outcome of carbon capture and utilization (CCU) to support clean production and environmental sustainability worldwide. This study included different phases. The first phase was an extensive reading of the literature, followed by a content analysis of the selected literature. The aim of the content analysis was to identify key concepts and the general categories of these concepts. The final phase was a content analysis of the selected literature with the purpose of identifying the relationship between concepts. The outcome of this paper is to provide a comprehensive framework of the customer value proposition of the CCU–formic acid product and consequently support global research efforts in sustainability. This framework contains two general dimensions: market knowledge and customer value. The first dimension includes five variables: the customers’ acceptance of CCU technology, the customers’ intention to purchase formic acid produced by CCU technology, the degree of customers’ knowledge about CCU technology, the customers’ readiness for environmental issues, and the market segments of formic acid product. The second dimension includes seven variables: ecological benefits, the ecological risk of CCU, varieties of formic acid use, the pricing policy of formic acid, the variety of formic acid packages, the order size, and the order frequency of formic acid. The relationship between variables was identified according to the literature and hypotheses were developed. This study has attempted to build a more comprehensive framework containing all proposed value dimensions and market knowledge as well as identifying the relationships between variables.

The importance of the sustainability concept has gained increasing attention from scholars and practitioners. In this context, the aim of this study was to examine the determinants of intention to continue to use the new Metro in Qatar, which is considered a sustainable mode of travel. Therefore, in this paper, a special attention was paid to certain variables, such as environmental concern, perceived quality, and perceived benefits. A quantitative method approach was employed, in which data were collected based on self-administered questionnaires. A total of 1334 Qatar residents responded to the survey questionnaire, and Structural Equation Modeling (SEM) was used for hypothesis testing. The results confirmed the direct effects of perceived behavioral control, social influence, and attitudes on the intention of residents to continue to use the Metro network in their travel. Moreover, perceived behavioral control was found to play a mediating role, enhancing the indirect relationship between perceived benefits and intention to continue to use the Metro network. More importantly, environmental concerns significantly and positively affected the attitudes and perceived behavioral control of travelers; furthermore, these variables presented a mediated influence—through service quality—on the intention to continue to use the Metro network. This study enriched the sustainability behavior literature by examining the influences of crucial factors. Thus, this study is considered of great value for policy-makers who hope to maximize the awareness level of environmental sustainability among the population, in order to encourage them to embrace changes in their lifestyle towards becoming more environmentally responsible.
