Anchored on the natural resource-based view and stakeholder theories, this study aims to investigate the mediating roles of sustainable supply chain management and green radical product innovation (GRPI) in the link between sustainable entrepreneurial orientation (SEO) and sustainability performance.

The comprehensive research model developed in this study is empirically tested by using data garnered from 248 managers of Ghanaian small and medium-sized enterprises. Partial least square structural equation modeling is applied as the methodological technique to test all the hypothesized relationships.

Results of the study indicate that SEO has a direct significant positive impact on environmental performance and social performance but not financial performance. However, through sustainable supply chain management and GRPI (both mediating variables), SEO tends to have significant impact on all sustainability performance dimensions (environmental, financial and social performance).

This study offers fresh empirical evidence by developing a unified research model that validates the specific mediation role of sustainable supply chain management between SEO and green radical product innovation, as well as the mediating roles of both sustainable supply chain management and GRPI between SEO and sustainability performance dimensions.

This study aims to examine the mediating role of trainer preparation in the effect employee trainer self-efficacy has on trainer performance.

Using a census, data was collected from internal employee trainers in two universities in Ghana. In testing the hypotheses, a structural equation modelling based on 10,000 bootstrap samples was used, and the BCa confidence intervals were used to establish the significance of the hypotheses.

This study revealed trainer preparation as a complementary partial mediator in the effect trainee engagement self-efficacy and instruction self-efficacy had on trainer performance. In addition, the importance–performance map analyses demonstrated that the factor with the most importance in the model was instruction self-efficacy, yet it was not the highest-performing factor.

This study highlights the mediating role played by preparation in the effect of trainer self-efficacy on trainer performance. In addition, it adds to the dearth of studies that focus on employee trainers while at the same time using data from the trainers themselves.

The purpose of this study is to investigate the growing trend of power outages in Ghana and the possible diffusion of a solar solution from the solar technologies; it also seeks to ascertain whether people in Ghana as well as developing countries would resort to renewable energy because of its “greenness”.

A focus group study was used, aimed at investigating the right parameters to be put in place for an effective diffusion of solar solutions in developing countries and, this instance, Ghana.

Results from the interviews of sampled respondents selected from different regions of the country indicated that many Ghanaians consider solar energy as the best alternative. However, it was a matter of affordability, financing and accessibility. Supplementary discussion into the benefits of resorting to “greenness” of solar energy, which seems not to be of major concern to potential users in Ghana, is highlighted. Moreover, making solar energy accessible in Ghana and the related market‐marketing conditions of the solutions are addressed. Based on the findings, a comprehensive examination of the reasons behind the slow adaptation of solar energy as an alternative is addressed. The alternative solar solutions identified include: standalone; backup and hybrid.

The study can be seen as the first in a series of attempts to understand the energy crisis in Ghana. The paper is aimed at promoting awareness of renewable energy solutions and its potential for helping the country to achieve a balanced economic growth.

The purpose of this paper is to compare how the various sectors among the largest companies in Ghana have incorporated sustainability into their mission, vision and value statements.

The mission, vision and value statements of the 100 largest corporations in Ghana, known as Ghana Club 100 (GC100), were extracted from the firms’ official websites. These firms were grouped into nine sectors, and the sustainability components in the mission, vision and value statements were subjected to cross tabulation and thematic contents analysis to establish the sectoral variations.

In formulating their mission, vision and value statements, GC100 firms were more than six times likely to include economic sustainability themes than environmental sustainability themes. Even though three out of every five GC100 firms are financial institutions, the manufacturing and the extractive sectors and firms ranked 1st−20th are three times likely to incorporate all the sustainability dimensions (i.e. economic, social and environmental) into their mission, vision and value statements. Firms in the financial sector and those ranked 80th−100th were more likely not to publish either a mission, vision or value statements online.

This study reveals the magnitude of the strategic pronouncements such as mission, vision and value statements of large firms in emerging economies and how they are aligned with sustainability. This could serve as a basis for formulating guidelines to reinforce efforts that contribute to corporate sustainability.

Research on how large firms align sustainability into their mission, vision and value statements is not a new agenda, but fragmented in the context of the emerging economies. The novelty is that this study addresses this gap and contributes to this topic from a sectoral comparative perspective of largest organization in Ghana, an emerging economy.

The study aimed to use geographic information system (GIS) based multi-criteria decision making analysis (GIS-MCDA) to select areas suitable for siting landfills in Ashanti region. It also sought to ascertain variables most sensitive to the siting of landfill in the region.

This study utilized GIS-based Multi-criteria decision making analysis –AHP to model and select areas most suitable to siting landfills within the region. Overall, 16 variables including wind speed and hydraulic conductivity (which were previously neglected in landfill siting in Ghana) were identified through comprehensive literature review. These variables were weighted using AHP method and integrated using the weighted linear combination (WLC) in GIS environment to develop five sub-models: the physical environmental, sociocultural, economic/technical, climatic and hydrogeological sub-models. These sub-models were further weighted and then integrated to derive the final suitability model.

Results show that 13% (3,067 km²) of the region was identified as most suitable to siting engineered landfills. The study also identified 11 sites which are considered most suitable for situating landfills. On a sensitivity angle, hydrogeological (R² = 0.5923; p = 0.003) and physical environmental sub-model (R² = 0.254; p = 0.034) significantly predicted the final suitability model developed.

Ghana's Landfill Guidelines seeks to optimize site selection and ancillary services that culminate into achieving sanitary landfills by 2020. Evidence still abounds on the unsuitability of existing and in some cases, new landfill sites presenting environmental and social negative impacts. The comprehensive evaluation of most crucial variables – social and environmental factors that determine an optimal landfill location – will be of immense help to policy planners like the Environmental Protection Agency (EPA) towards upgraded landfills. The authors hope that, concerned agencies will adopt the model in the study and integrate into their existing landfill suitability modeling techniques to provide a more grounded framework that optimizes landfill site selection within the study area.

This study is the first attempt to consider a regional-level waste collection site selection in Ghana using comprehensive sets of social and environmental factors and will therefore contribute immensely to EPA's goal of achieving upgraded landfills by 2022.
