Risks and Opportunities

Energy crisis resulting from the conflict between Russia and Ukraine is one of the causes of energy fluctuations and shortages in the global market. As a consequence of this crisis, there has been a shift towards more efficient energy usage worldwide. Many countries have declared plans to reduce their reliance on fossil fuels and accelerate the transition to clean and renewable energy sources. These changes align with efforts to address global climate change issues and the continuous rise in global temperatures. Consequently, there have been water resource shortages, droughts, and threats to human rights, particularly in terms of health and livelihood due to food and clean water shortage.

However, the Company has prepared to address these changes by implementing sustainable energy management policies and consistently being environmentally friendly. The Company is dedicated to developing renewable energy sources such as solar energy, wind energy, geothermal energy, biomass energy, as well as electric vehicles for transportation. Additionally, the Company also put an emphasis on water management, which is a crucial resource for both livelihood and business operations. It can also serve as a significant renewable energy source in the future.

The Company aims to increase its share and develop renewable energy to reduce greenhouse gas emissions from business activities. The Company also efficiently manages water to minimize the risk of community rights violations in accessing clean water. Furthermore, the Company supports projects to enhance water efficiency, conserve water, and set continuous short-term and long-term energy reduction targets. This is to monitor energy usage and mitigate the severity of environmental, social, ethical, and economic impacts resulting from climate change, as well as impacts to human rights.

Management Approach

The Company continues to pursue proactive goals under the "7 Go Green" strategy. Additionally, the Company has elevated its energy management practices to the ISO 14OO1 standard and implemented projects within the framework of the 7 Go Green strategy. Several projects were initiated under the strategy, such as the Green Store Project, Green Logistics Project, Green Packaging Project and Green Living Project.

However, the fluctuating energy prices, energy shortages in the global market, and political instability worldwide have led to an overall increase in energy prices in Thailand. This directly impacts the costs and returns of business operations. Therefore, the Company has reduced unnecessary energy consumption, improved energy efficiency, increased the proportion of renewable energy usage, and continuously developed clean energy technologies to mitigate environmental impacts and enhance business resilience and sustainability alongside continuous organizational development.

Environmentally friendly shops, retail centers, distribution center and manufacturing plants (Green Store)

The Company operates under the environmental strategy "7 Go Green" consistently throughout its value chain. This includes continuous efforts to improve energy efficiency and increase the proportion of renewable energy usage. As a result, the Company is able to reduce energy costs and greenhouse gas emissions from its business operations. In 2O23, projects supporting the Green Store strategy were implemented in four operational areas, as follows:

Increase power management efficiency

Increase renewable energy usage proportions

Improve cooling systems and utilize environmentally friendly refrigerants

Cultivate consciousness and change employees' behavior
