Reduce GHG emission and utilize renewable energy in most possible extent in our operation

The issue of climate change has grown in importance and urgency at both the national and global levels in recent times. International, state, private and consumer organizations have all supported cooperation and pushed forward measures to reduce greenhouse gas emissions in line with the Paris Agreement (COP21). AIS is aware of the challenges and opportunities to our business from the aforementioned issues. Apart from policy and legal challenges, AIS also consider the risks from natural occurrences that are only growing more severe are more difficult to predict, as they pose a threat to its network and our subscribers, especially during this age of digital technology in which communication is a major necessity for economic growth and social normality. AIS has begun expanding its expertise in order to develop ICT services with reduced GHG emissions as well as a system for analyzing and alerting against natural disasters to mitigate impacts that may stem from climate change towards our customers, operators and society. Determined to reduce energy consumption, and to prepare accordingly to handle climate change, AIS sees positives for its capital structure and reduce risk to its business in the long term.


To demonstrate our commitment to the reduction of GHG emissions, we have set the following goals toward 2023

  • 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.
  • Increase renewable energy usage to 5% of total energy consumption compared to 0.06% in 2018.

AIS believes that it is our responsibility to address climate change through leveraging our capability and innovation. We put our efforts to constantly reduce of GHG emissions and improve energy efficiency in our operations as well as in the development of new products and services. In the meantime, we also promote a green value chain among our partners, suppliers, and distributors.


Our recent efforts to counter climate change are as follows:

AIS is committed to its mission of playing a part in combating global warming and carries out various projects to reduce GHG emissions, including, enhancing the energy efficiency of our network and data centers, utilizing alternative energy and reducing paper usage.

  • Energy Efficiency

    Enhanced energy efficiency of the telecommunications network by installing several pieces of collaborative remote multi-mode radio units and upgrading power supplies as well as by expanding the energy saving Virtual Machine Server

    GHG emissions from energy efficiency programs

  • Use of Renewable Energy

    From 2000 through to 2019, AIS has commenced an alternative energy program based on solar energy, which has generated a total of 3,489 MWh

  • Reduction of paper usage

    AIS utilizes digital technology for a variety of its transactions whether internally, with its business partners or even with its customers, reducing paper usage and travel while also increasing efficiency and convenience for customers
