Abstract: Greenhouse gases such as sulfur dioxide, nitrogen dioxide, and carbon dioxide have been recognized as the prime cause of global climate change, which has received significant global attention. Among these gases, carbon dioxide is considered as the prominent gas which motivated researchers to explore carbon reduction and mitigation strategies. Research work on this domain expands from carbon emission reporting to identifying and implementing carbon mitigation and reduction strategies. A comprehensive study to map global research on carbon emissions is, however, not available. Therefore, based on a scientometric analysis method, this study reviewed the global literature on carbon emissions. A total of 2945 bibliographic records, from 1981 to 2019, were extracted from the Web of Science core collection database and analyzed using techniques such as co-author and co-citation analysis. Findings revealed an increasing trend of publications in the carbon emission research domain, which has been more visible in the past few years, especially during 2016–2018. The most significant contribution to the domain was reported from China, the United States, and England. While most prolific authors and institutions of the domain were from China, authors and institutions from the United States reported the best connection links. It was revealed that evaluating greenhouse gas emissions and estimating the carbon footprint was popular among the researchers. Moreover, climate change and environmental effects of carbon emissions were also significant points of concern in carbon emission research. The key findings of this study will be beneficial for the policymakers, academics, and institutions to determine the future research directions as well as to identify with whom they can consult to assist in developing carbon emission control policies and future carbon reduction targets.

Abstract: Whilst operational carbon (OC) emission reduction has received greater attention in the literature, embodied carbon (EC) emission reduction aspect has been largely neglected. This is particularly seen in developing countries. This study assessed the awareness and perception of carbon emission in general and EC emission reduction strategies in particular in the Sri Lankan construction industry. A detailed questionnaire, based on a comprehensive literature review, was developed to assess the awareness and perception of the Sri Lankan construction professionals about global carbon emissions, OC emissions, and EC emissions and carbon mitigation strategies. Based on a s le of 111 professionals in the construction sector, results revealed that the Sri Lankan construction professionals have poor awareness about carbon emission, especially about EC emission and EC mitigation strategies. The results further revealed that they are more concerned about the OC emission reduction than the EC emission reduction. The results suggest that they are basically aware of some basic/conventional mitigation strategies such as better design (low-carbon), an extension of building life and refurbishment of existing buildings and carbon tax, but their awareness of recently introduced micro-level technologies/strategies is significantly poor. Findings are a clear reflection of the current situation in many developing countries with regard to carbon emission and mitigation strategies. It was found that a major reason for low awareness was related to the culture: The majority of the respondents believed that actions to reduce carbon footprint should be initiated and handled by the government and other authorities, but not by construction professionals.

Abstract: The need to mitigate climate change has become a major global concern, and greenhouse gas emissions are a major cause of global climate change. Therefore, the need to curb greenhouse gas emissions has been well recognized by global researchers, policymakers and academics. Carbon emissions of hotel operations have seized the attention of global researchers. However, carbon emissions of the hotels in developing countries remain to be a less explored domain. Therefore, carbon emissions of Sri Lankan hotels were explored using a case study approach. Five hotels in the Colombo suburb were explored, which revealed that each hotel released more than 7000 tons of carbon annually. Results further indicated the use of purchased electricity as the dominant source of carbon emissions. Emissions caused by transport activities were not included in the calculations due to the unavailability of data. Recommendations were made to overcome the issues identified during data collection as well as to reduce the carbon emissions from hotel operations. Wider adoption of the methodology used in this research will benefit the hotels to keep track of the carbon emissions using a systematic approach.
