WEB APPLICATION SUPPORT FOR CARBON FOOTPRINT MANAGEMENT OF PETROL STATIONS IN THAILAND

Abstract

In Thailand, a “petrol station” is considered an “organization” that not only sells fuels and engine
lubricants for motor vehicles but also includes many other facilities provided to satisfy the modern lifestyle of
customers. In other words, a petrol station in Thailand comprises a large complex service center offering a wide
range of services that contribute greenhouse gas emissions to the atmosphere. This paper aimed to present a
specific web application tool developed to estimate the carbon footprint for petrol stations in Thailand. The
application system comprises three core components: 1) a web-based user interface; 2) a processing system,
incorporating the carbon footprint of the organization (CFO) framework and the calculated model and 3) a
database. The site-specific input data or activity data provided by the user was primarily required for the data
entry in the system. The processing system will then quantify the amount of greenhouse gas emissions by
multiplying the activity data by the emission factor (EF). A database was also created containing default EFs
readily used for the calculation, but users can change these values at any time when a more appropriate one is
indicated. Finally, the CF calculation results can be evaluated in various functional units: monthly or yearly, per
fuel sold, or per area of the petrol station, and visualized in graphs. In addition, the results can be reported by
categorizing the emission sources according to the scope of the CFO and the GHGs reporting guidelines (scopes
1, 2 and 3)
