*Remark: the average electricity expense per unit was 4.20 baht which is calculated from the electricity consumption (unit: kWh) per month between October – December 2020. The results show that the average expense per month were 4.09, 4.36, and 4.15 baht per unit. Therefore, the average price of 3 months was at 4.18 baht per unit. Then, the average price is used to calculate the Company’s electricity expense per month in 2021 to get the estimated electricity consumption. (unit: kWh)

Scope 3: Other Indirect GHG Emission

The calculation is made from the paper consumption and the use of water supply (information covering the entire Head Office and every branch office nationwide account for 100 percent) which can enumerate measures and performance based on Scope 3 as follows:

Paper consumption measure

  1. The Company encourages all departments in the organization to cooperate in reducing the paper usage by campaigning to choose to print and use paper on both sides.
  2. The Company has developed an electronic receipt (e-Receipt) in accordance with the rules and practices in line with the Revenue Department. The project was started for the pilot operation in October 2020, which can help reducing 5,300.20 bills or equivalent to 11,544.44 kg or help reducing carbon footprint for 7.71 tonCO2e. In this regard, the scope of the e-Receipt Program will be extended to cover all branch offices nationwide by April 2021.

Green product purchasing measures

The Company promotes the purchase of environmentally friendly products in the category of office equipment at the Head Office according to the criteria of the Pollution Control Department. In the year 2020, the Company has started to purchase the green label certified toilet paper and A4 paper (only at the Head Office).

Operational performance report of Green Building

In 2020, the new Head Office building of the Company which was a green building or an eco-friendly building was still under construction. It has not been completed yet. As the Company has given importance to the issue of climate management in the long term, the Company has prepared a plan to cope with the Green Building Design. This includes the selection of environmentally friendly materials and equipment under the LEED Green Standard Guidelines, Gold Level (Version 4) by the US Green Building Council of the United States. This results in the new Head Office building of the Company to be the building that shows how beautiful it can be combined with energy savings without compromising on the quality of life of building occupants in any way. It is also designed to support the principles of universal design with a system to facilitate the elderly.

The new Head Office building is a 14-storey office building with a total utility space of 12,900 square meters and has passed the environmental impact assessment (EIA) according to the standard criteria in June 2018 (construction period) and January 2020 (construction completion period). In 2020, the Company can report the environmental impact which is divided into impacts during the construction process and the impact during construction completion as follows.

Air quality of general atmospheric

Control on construction dust concentration Total Suspended Particulate (TSP) when being combined with the results of the air quality measurement of the project was 0.163 mg / m3 which did not exceed the standard of atmospheric dust concentration of 0.33 mg / m3 according to the Notification of National Environment Board No. 24 B.E.2547. The result shows air quality index measured was in the setting required standard. However, after construction, the Company still follow the required protecting policy and solve the effect of the air quality significantly by cleaning the outbound area, including the access road to the area to protect the dust and the explosion of it when passing the entrance-exit of the area.

Control on noise level

Buildings adjacent to each side of the project were affected by noise approximately 64-65 dB (A) which did not exceed 70 dB (A) according to the standard of 24-hour average noise level and a noise factor of -1.6 to -0.9 dB(A). This did not exceed the noise level 10 dB (A) of the basic sound level the Notification of National Environment Board No. 29 (B.E.2550). The initiation of the sound is from the construction of the Company which had drilling and hammering activities. Currently, the construction has been completed. The effect of the sound has disappeared, leaving only the sound from traffic and social activities in the surrounding areas.

Waste management

There was waste that could be recycled including iron, ceramic tile, roof tiles, gypsum board and wood accounted for 9.57% of total building construction waste or 466.36 m3. The waste to be disposed consisted of concrete and bricks for 4,406.79 m3
