Reducing GHG emissions through high efficient business operations and utilization of renewable energy

In recent years, the global community encompassing international, state, private organizations as well as consumers have supported cooperation and attached more significance to the issues of climate change. In 2021, Thailand pledged to accelerate action to achieve net-zero emissions by 2065 out of the concern that Thailand is one of the top 10 countries most affected by climate change and to join the global community in immediate efforts to fight climate change.

AIS is well aware of the challenges and risks arising from such issues on the Company’s business operations. With a strong determination to be part of the global action to tackle climate change, AIS has studied science-based targets in formulating comprehensive plans to reduce GHG emissions. Added to this are preparation for climate change impacts and developing businesses that help support GHG emission reduction in different sectors.

Science-based Targets Initiative (SBTi)

SBTi is setting a GHG emissions reduction target grounded in science in line with the main target of the Paris Agreement, which is to limit global warming to below 2, preferably in the best case to 1.5 degrees Celsius above pre-industrial levels.


AIS is committed to its mission to play a role in mitigating global warming, having carried out scores of core projects on energy efficiency, GHG emission reduction, promoting the use of renewable energy, reducing paper use, and developing smart solutions to empower AIS customers to take part in tackling the global warming issue. Towards these commitments, AIS has set short-, medium- and long-term goals for reducing greenhouse gas emissions with the head of its technology executives tasked with carrying out the effort and implementing environmental management across the organization, from its core business to its auxiliary endeavors.

To demonstrate our commitment to the reduction of GHG emissions, we have set the following goals toward 2023.
  1. Reduce GHG emissions intensity, calculated from the ratio of GHG scope 1 and scope 2 emissions to data traffic by 90% compared to the baseline in 2015
  2. Increase renewable energy usage to 5% of total energy consumption compared to 0.06% in 2018.


Promoting Energy Efficiency

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 by 27,543 tCO2e

Network energy efficiency programs
Alternative Energy Use

In 2021, another 2,748 solar panels were installed, resulting in the number of base stations, data centers, and switching centers, powered by renewable energy adding up to 5,561 and a reduction of 8,139 tCO2e in GHG emissions.

Environmental Management System (EMS) Development

The AIS environmental management system received ISO14001:2015 approval. The system used independent evaluators at two AIS computer data centers and ISO14001 certified environmental experts at all others.

Paper Use Reduction

AIS integrated digital technology into its internal operations, processes involving partners and in service of customers under the Full-E concept. On top of reducing paper usage and the need for travel, these services also enhance operational efficiency and convenience for customers.

By the end of 2021

  • myAIS usage reached 8.4 million users, increasing by 3.1%.
  • 8.38 million billing accounts switched from mailed bills to E-Bills
  • 109 million E-Receipts

all together cutting the need for sheets of paper, equivalent to 10,459 tCO2e in GHG emissions a year.
