The study determined the critical variables inducing the choice of mitigation and adaptation methods adopted by the Small and Medium Scale Enterprises (SMEs) against the effect of climate change on their enterprises in Southwest Nigeria. A multistage sampling procedure was employed to choose 200 SMEs Managers/Chief Executive Officers (100 mitigating climate change and 100 not mitigating) as respondents for the study. Descriptive statistics and a multinomial regression model were employed to investigate the data collected. The findings show that the mean age of Managers/CEOs mitigating climate change was 41.8 years, and the level of education of climate change mitigating Managers/CEOs (80.0%) was significantly different from the non-mitigating (50.0%). The net profit margin ratio for the mitigating SMEs was 32.04%, and 17.83% for the non-mitigating SMEs. The multinomial logit model showed that income, enterprise experience, access to credit, enterprise size, and enterprise type significantly induced the choice of climate change mitigation approaches used by the SMEs in the study area. The study suggested that government and Non-Governmental Organizations (NGOs) should assist SMEs by enhancing their income-generating ability to ameliorate the impact of climate alteration over the years on their enterprises.

Adopting a long-term perspective has helped companies survive in difficult times and overcome economic crises, recessions, and pandemics such as the current COVID-19. At present, the project management approach is changing from more authoritarian management models to frameworks that are based on the management of people and society. This article researches the concept of sustainable leadership in the project management profession. It evaluates the level of sustainable leadership among project managers in Spain using the Avery and Bergsteiner’s (2011) model of bees and locusts as a reference framework (Bee and Locust Sustainable Leadership Model). A qualitative study was carried out based on the analysis of the responses given by sixty-eight project managers in Spain who answered a 52-point ques-tionnaire. The findings yielded interesting results. It was found that in projects considered as temporal organizations, companies tended to employ a mixture of bee and locust’s leadership elements. Respondents recognized the importance of employee training and development, and most considered that it was essential to consider the environment when determining the organization’s commercial objectives. However, based on this study’s findings, the project management profession still has a long way to go as regards the practical implementation of sustainable leadership.

Disaggregated data is often used to model the cost-benefit of residential energy management systems. However, obtaining such data is time-intensive and monetarily expensive. This hinders the depth of analysis that can be done on these systems
Disaggregated data is often used to model the cost-benefit of residential energy management systems. However, obtaining such data is time-intensive and monetarily expensive. This hinders the depth of analysis that can be done on these systems and negatively influences their large-scale uptake. This study proposes a novel generalised model of these systems that uses smart meter load profile data to model their cost-benefit. Using two years of half-hourly electricity consumption data from 5379 households in London, the model was used to examine how sociodemographic, tariff structures, and the choice of operational objectives of these systems, interact to influence their cost-benefit. The results showed that the proposed model produced reliable cost-benefit results within what is normally obtained in literature. The model demonstrated that applying one set of objectives to different customers leads to an inequitable distribution in benefits; rather, an optimal set of objectives for a given customer under a specific tariff structure can be found to produce a more equitable distribution in benefits across all customers. The proposed model is replicable and uses data that can be obtained easily and cheaply from smart meters, making it versatile for large-scale cost-benefit analysis by any electricity retailer.

The Carbon Footprint (CF) of agriculture must be substantially reduced to help avoid catastrophic climate change. This paper examines the ratio of Greenhouse Gas (GHG) emissions to protein as an indicator of the CF of the major Canadian livestock commodities using previously published results. The GHG emissions for these commodities were estimated with a spreadsheet model that accounted for all three GHGs, the complete life cycles of each livestock type and the livestock interactions with the agricultural land base. The indicator results reviewed here included the responses to livestock types and diets, livestock versus plant protein sources, spatial scales and geographic differences. The sensitivity of the results shown suggest that GHG-protein ratios could provide valuable guidance for producers and consumers to reduce their GHG emissions. For example, diverting feed grains from beef feedlots to hog production would substantially reduce the CF of red meat, although still not as low as the CF of poultry products. The complete proteins derived from pulses have much lower CF values than all livestock products.

The market share of e-bikes has increased extensively in Europe over the last decade. How this trend will affect the transport system depends to a large extent on the substitution effect which needs to be determined in detail to allow projections on the potential of e-cycling as a means to promote sustainable transport systems. Further, little is known about what psychological determinants influence e-bike use, an important topic for policy makers that wish to promote e-cycling. This study aggregates GPS data from two randomised controlled trials in Sweden to determine the effect of e-bike use on travel behaviour. Motives behind e-bike use are investigated within a pathanalytic structural model, based on an expanded theory of planned behaviour. The results reveal that, on average, total cycling increased by 4.5 kilometres per person and day during the trials and its modal share measured in distance increased by 19%. E-bike use was predicted by the intention to bike to work, which in turn mediated the effects of attitudes and self-efficacy on e-cycling. Attitude mediated the indirect effect of personal norm on intention and collective efficacy amplified the effect of self-efficacy on intention. The results show that e-cycling has a large potential to contribute to a sustainable transport system. Policy makers could increase the use of e-bikes by strengthening individuals’ attitudes toward cycling and perceived self-efficacy to e-cycle, by making environmental personal norms more salient and by highlighting collective action in the effort to limit environmental degradation.
