The Company has thus set the strategies and management approaches to deal with the climate change by dividing into two areas, which are:
The Company is well aware of the importance of a cooperation amongst all sectors to reduce the greenhouse gas emission. As such, it has integrated a “Climate Change Management Policy” into the determination of the Company’s goals and business plan toward a low carbon city which focuses on energy efficiency by 2040 and a reduction of direct and indirect greenhouse gas emission (Scope 1 & 2) intensity by 30%, compared to the 2019 base year, within 2030.
The Company has reported the direct greenhouse gas emission (Scope 1), indirect greenhouse gas emission from energy use (Scope 2) and other indirect greenhouse gas emission (Scope 3) data referring to the Approved Consolidated Methodology from the Carbon Footprint for Organization of Thailand Greenhouse Gas Management Organization (Public Organization). In this regard, the greenhouse gases used in the calculation consisted of Carbon dioxide (CO2), Methane (CH4), Nitrous oxide (N2O), Hydrofluorocarbon (HFC6), Perfluorocarbon (PFCs), Sulfur hexafluoride (SF6) and Nitrogen fluoride (NF3). The Company collected the greenhouse gas emission data for carbon footprint calculation once a year. The scope of disclosure covered the activities in three offices of the Company and in the common areas of AMATA City Chonburi Industrial Estate and AMATA City Rayong Industrial Estate which are under the responsibility of the Company.
In 2021 the Company’s 2020 carbon footprint of the organization (CFO) was certified by Thailand Greenhouse Gas Management Organization (Public Organization) for the second year.
In 2021 the Company emitted 12,219 tons of carbon dioxide equivalent (tCO2e) of direct and indirect greenhouse gas (Scope 1&2), comprising 470 tons of carbon dioxide equivalent of direct greenhouse gas (Scope 1) and 11,749 tons of carbon dioxide equivalent of indirect greenhouse gas from energy use (Scope 2). Such emission decreased by 24.7% compared to the previous year, and by 32.1% compared to 2019 base year. The 2021 greenhouse gas emission data are still under review by the Centre of Excellence on Environmental Strategy for Green Business (VGREEN), Kasetsart University. It is expected to complete by the 2nd quarter of 2022.
The combined greenhouse gas emission (scope 1&2) intensity in 2021 stood at 2.1 tons of carbon dioxide equivalent per million Baht, a 28.2% reduction compared to that in 2019 base year. A decrease in combined greenhouse gas emission intensity resulted from the Company’s Work-from-Home measure during Covid-19 pandemic which lowered the use of electricity and gas for transportation, and significantly increasing use of renewable energy in AMATA Industrial Estates aimed to reduce the use of electricity bought from external parties.
The Company is aware of the importance of a reduction in greenhouse gas emission, especially indirect greenhouse gas emission from purchased electricity (Scope 2) used in its main activities. As such, the following operational guidelines for a reduction in purchased electricity consumption in main activities are determined:
electricity consumption in common areas of the industrial estates
electricity consumption in water pumping and sprinkler systems
electricity consumption in office buildings
The Company has organized the activities continuously to promote the Company’s employees and the tenants in the office building to obtain more knowledge about the energy consumption reduction in the building by focusing on building every employee’s awareness to participate in energy conservation and the appropriate consumption of natural resources and environment to achieve sustainability; e.g. campaign to turn off air conditionings and unnecessary lights, campaign to use the stairs instead of elevators and adjustment of the temperature of air conditioning system in the offices not to be lower than 24 degrees Celsius, and turn-off of the screen of computer’s monitor every time when not in use, etc.
In 2021, the Company's office buildings had a total electricity consumption of 436,179 kWh, or a decrease of 20% from that in 2020 as a result of work-from-home measure during COVID-19 pandemic and the change in patterns of work whereby the employees can work from anywhere.
In term of common areas of the industrial estates, the Company is responsible for all road lighting systems within the industrial estates. In 2021, energy consumption in common areas increased by 7.29% due to an expansion of new developed areas. All lighting systems in common areas of both industrial estates are LED light bulbs (100%). Smart control system was installed in lighting control boxes to enhance the efficiency of lighting system. Additionally, the Company installed solar traffic lights in 112 locations in AMATA City Chonburi Industrial Estate and AMATA City Rayong Industrial Estate for energy conservation.
The Company has encouraged its subsidiaries within supply chain to increase the energy efficiency and to reduce purchased electricity consumption particularly in water system for industrial use which consumes the highest amount of energy. AMATA Water Co., Ltd., in charge of water and wastewater management in AMATA Industrial Estates, has studied on how to adopt solar energy to replace the electricity power in the operational process. It has commenced the installation of solar roof system at the water supply production plant with water reclamation system since 2017.
In 2021, AMATA Water Co., Ltd. had installed three additional solar panels consist of one ground-mounted solar panel and two floating solar panels in the reservoirs at AMATA City Chonburi Industrial Estate and AMATA City Rayong Industrial Estate. As a result, total capacity of electricity generation from solar cells was increased by 2,152 kWh, accounting for 426.28% of total capacity in 2020. Total self-generated electricity in 2021was 3.81 million kWh meanwhile the greenhouse gas emissions were reduced by 1,647.28 tons of carbon dioxide equivalent per year.
