This is an independent study on greenhouse gas emissions and ways to reduce them. A five-star resort in Koh Samui Surat Thani province has been used as a case study. The study used digital tools to gather information on activities that cause greenhouse gases and energy consumption at the resort. The calculation of carbon footprint is in line with the guidelines of the Thailand Greenhouse Gas Management Organization. Digital systems help data collection and carbon footprint analysis and this is best done at set intervals. For example digital systems can monitor power consumption every 15 minutes measured in real time. The carbon footprint maximum emission each day occurs between 2.00 and 4.00 pm the peak time of energy consumption. Use of electricity is the activity that produces the highest amount of greenhouse gases at a total volume of 4215.1 tonCO2-e per year or 88.12% of the total activity. LPG gas consumption produces the second largest volume of greenhouse gas emissions at 412.8 tonCO2-e per year or 8.63% of the total activity. From January to December 2017 the carbon footprint emission is 4783.5 tonCO2-e and the average emission per room night is 4.2 tonCO2-e. The study found that a 10% reduction in energy Consumption could reduce greenhouse gas emissions by 421.52 tonCO2-e per year or 0.4 tonCO2-e per room night.
