1 Determinants of CSER practices for reducing greenhouse gas emissions: From the perspectives of administrative managers in tour operators
عوامل تعیین کننده اقدامات SCER برای کاهش انتشار گاز گلخانه ای: از نقطه نظر مدیران اجرایی در عملگران گردشگری-2018
Responsible corporate action has long been recognized as a vital step toward sustainability. Recently, this notion has also been introduced in tourism practices. Consequently, researchers have gradually become involved in exploring how tourism CSER is practiced, what might motivate it, and the relationship between financial performance and accredited actions. However, studies have primarily focused on the hospitality, airline, and cruise industries, and been geographically limited to Europe and North America. In order to fill this research gap, this study measures Taiwanese tour operators CSER activeness in reducing GHG emission according to a comprehensive set of items ranging from firm operation to destination management. Particularly, an extended TPB model has been employed to examine significant predictors of CSER performance, from the perspective of administrative managers. The findings indicate that managers’ attitudes regarding the benefits to the society and company interests are the most important predictors of business operations, supply chain, and destination management in CSER practices, respectively. The age of tourism business also plays an important role. This study contributes to the theoretical enhancement of CSER and TPB. Also, several practical suggestions are proposed in this study that will enhance the CSER profiles of tour operators.

2 A model to control environmental performance of project execution process based on greenhouse gas emissions using earned value management
یک مدل برای کنترل عملکرد محیطی فرآیند اجرای پروژه برمبنای انتشار گاز گلخانه ای با استفاده از مدیریت ارزش درآمدی-2018
In response to recent climate change, which is believed to be attributed to the release of greenhouse gas (GHG) emissions, many countries are placing CO2 abatement programs such as carbon tax and cap-and-trade. Projects do have a significant share in GHGs and therefore their environmental performance, like their schedule and cost performance, should be monitored and controlled. Although many large projects would pass an environmental assessment in the project evaluation phase, the issue of environmental performance monitoring during the project execution phase has not been addressed in project management methodologies. The objective of this paper is to develop a model to estimate project GHG emissions, and to measure project GHG performance using the developed metrics, which can be used at any point in time over the life of a project. A comprehensive study is conducted to collect information on GHG emission factors of various project activity data (such as material use, energy and fuel consumption, transportation, etc.), and a user form interface is developed to calculate the total GHG of an activity. Also, a breakdown structure is proposed which supports managing all the project GHG accounts. The monitoring and control model is formulated based on the logic used in earned value management (EVM) methodology. The proposed model is then implemented to a work package of a real construction project. The results present the project initial GHG plan and show that the model is able to calculate project GHG variance by the reporting date and predict project final GHG based on a project GHG performance index. The method presented in this paper is general and can be applied to any type of projects in an organization that aims to reduce its carbon footprint. The same structure can be applied to monitor and control any other environmental impact associated with project execution process.
