Climate Actions

AIS is aware of risks which may impact the company’s business such as 1) Natural disasters, 2) Changes to state policy and regulations, which is trending to control greenhouse gas emissions, and 3) Changing consumer preferences which give more attention to the environment. The company is also attentive to the business’ impact on the environment. AIS has thus adjusted its environmental targets to be more challenging with Science-based Targets for reducing GHG emissions, involving support all along the value chain, and adapting the company to be more environmentally friendly.

Management Approach

The Chief Technology Officer is responsible for the environmental management program for the entire organization, and reports progress to the Sustainability Committee* and the Board of Directors at least once a year. There are also environmental policies in the workplace which were moat recently updated in 2022.

The objectives of the policy are to promote environmental sustainability as follows:

Our Actions

Increased Energy Efficiency

Efficiency is increased through the study and analysis of customers’ behavior together with adopting power saving features in planning, and appropriate use of network infrastructure, reducing energy consumption and GHG emissions.

Increase in the use of electricity from renewable sources

In 2022, AIS expanded its solar panel installations to supply base stations and switching centers to increase the proportion of our renewable energy. In 2022, AIS took significant steps to increase the proportion of renewable energy by installing additional solar panels to supply base stations and switching centers. The capital expenditure for this solar project amounted to 283.5 Million Baht. These efforts align with the objectives of the Thailand Taxonomy, demonstrating AIS's commitment to sustainable practices. Since the Thailand Taxonomy Board recently issued Thailand Taxonomy phase 1 for the energy and transportation sectors in 2023, this is an initial step for AIS to voluntarily apply the Thailand taxonomy and assess the level of sustainability of our business activities, which will be beneficial for transitioning our business towards sustainable future.

Environmental Management System Development and training for employees

The AIS environmental management system received ISO14001:2015 standard at AIS computer data centers, which are verified by independent external verifiers. Moreover, AIS provides learning courses for employees in related departments to enhance their understanding and expertise in applying environmental standards from ISO14001:2015 and energy management standards from ISO50001 on their jobs. In 2022, 132 employees have participated in the courses on ISO Standard and Certificate. See more detail in Environmental Management System certification from the Related Documents.

Water Efficiency and Water Recycling

In 2022, Cooling systems of data centers must use purified water that has been filtered by a Reverse Osmosis (RO) system. However, partly filtered water from RO system cannot be used for the cooling system, approximately 30 percent of total water. Then, we use this water to clean the solar rooftop of the data centers. This helps improve the efficiency of solar panels and it's also an efficient use of water.

Moreover, we have initiated a pilot project to reduce water consumption at a data center by using an environmental friendly Electronic Anti Scale system instead of the reverse osmosis systems, reducing water use by up to 30 percent. We will expand this pilot project to other data centers to reduce water used in cooling systems.

Biodiversity and Forest Protection

AIS is committed to conserving and protecting biodiversity and ecosystems in its business operations. To that effect, the company has implemented integrated management and adopted internationally accepted metrics to assess its operations. The goals are to achieve No Net Loss of Biodiversity and No Net Deforestation by 2027. For further information, please visit operations to promote biodiversity and conserve forest.
