The Company is committed to developing its industrial estates into environmentally sound cities that enhance the quality of life for both workers within the estates and members of surrounding communities. As part of this vision, the Company has set a target for all industrial estates to have green areas at least 10 percent of the total operational area. The Company has prepared a master plan and determined green area development within AMATA industrial estates annually to continuously restore green areas in AMATA industrial estates. It defines types of plants based on forest types in Chonburi and Rayong provinces, according to the Royal Forest Department. Most terrestrial forests in Chonburi and Rayong are mixed-deciduous forests and dry evergreen forests. The expansion of green areas within industrial estates not only contributes to enhancing biodiversity indices, but also serves as a buffer zone to mitigate pollution impacts and provides recreational areas for employees, workers of tenant companies, and surrounding communities, enabling shared use and benefits.

The total project area of AMATA City Chonburi Industrial Estate is 20,195 rai (3,231 hectares), with a total operational area of 18,526 rai (2,964 hectares) and a total green area of 2,121 rai (339 hectares), representing 11.45% of the operational area. In 2025, the Company did not undertake additional tree planting within AMATA City Chonburi Industrial Estate. However, tree replanting was carried out to replace dead trees, together with landscape enhancement activities. The Company also consistently maintains common green areas to ensure they remain well‑managed and visually appealing. All replacement trees were of 100% native species, ensuring alignment with local biodiversity conservation efforts. According to the Royal Forest Department report, these trees are categorized as mixed-deciduous and dry evergreen species that are tolerant of saline soil conditions, such as Siamese Rosewood (Dalbergia cochinchinensis), Gurjan (Dipterocarpus alatus), Bungor (Lagerstroemia calyculata), Horse Cassia (Cassia grandis), Kalamona (Cassia surattensis), Yellow poinciana (Peltophorum pterocarpum), Thai crape myrtle (Lagerstroemia speciosa), Trumpet Tree (Dolichandrone serrulata), Broad-leaf mahogany (Swietenia macrophylla), Burmese Padauk (Pterocarpus macrocarpas), Tamarind (Tamarindus indica), and Manila tamarind (Pithecellobium dulce), etc.

The total project area of AMATA City Rayong Industrial Estate is 17,898 rai (2,864 hectares), with a total operational area of 15,855 rai (2,537 hectares) and a total green area of 1,671 rai (267 hectares), representing 10.54% of the operational area. In 2025, the Company planted 1,000 native trees in AMATA City Rayong Industrial Estate with a survival rate of 90%, continuous replanting efforts are in place to replace any seedlings that do not survive. All trees planted are 100% native species found in Rayong province. According to the Royal Forest Department report, these trees are categorized as mixed-deciduous and dry evergreen species, such as Afzelia burl (Afzelia xylocarpa), Java Plum (Eugenia cumini), Gurjan (Dipterocarpus alatus), White Meranti (Shorea roxburghii), Bungor (Lagerstroemia calyculata), Thai copper pod (Senna siamea), Tamarind (Tamarindus indica), Queen's Flower (Lagerstroemia speciosa), and Broad-leaf mahogany (Swietenia macrophylla), etc.

AMATA Smart City Industrial Estate in Chonburi covers a total area of 5,354 rai (857 hectares). The Company has been developing this new industrial estate since 2023, with a planned operational area of 4,600 rai (736 hectares). Of this area, 564 rai (90 hectares) has been designated as green area, representing 12.26% of the planned operational area. This industrial estate is currently undergoing further development.

AMATA City Chonburi 2 Industrial Estate covers a total area of 1,941 rai (311 hectares). The Company has been developing this new industrial estate in 2024, with a planned operational area of 1,941 rai (311 hectares). Of this area, 244 rai (39 hectares) has been designated as green area, representing 12.57% of the planned operational area. This industrial estate is currently undergoing further development.

In collaboration with factory operators in the AMATA Industrial Estates, the Company has initiated projects to revitalize abandoned public areas into community forests by planting native perennial plants in the degraded forest areas of the industrial estates. For instance, in the "Forest for Life" project spanning from 2019 to 2025, the Company partnered with Tokai Rika (Thailand) Company Limited to reforest a 12-rai public area in AMATA City Rayong Industrial Estate.  In 2025, 3,500 trees were planted on 2 rai of land, and a total of 32,500 trees were planted on 12 rai of land during the project period.

Moreover, the Company has partnered with the AMATA City Rayong Industrial Estate Office and the Bang Lamung Forest Conservation and Development Unit to launch the "Green Expansion and Natural Resource Conservation Cooperation Project (Community Forest Planting)" in the Bang Lamung National Reserved Forest, Moo 1, Khao Mai Kaeo Subdistrict, Bang Lamung District, Chonburi Province. This initiative aims to extend the development efforts beyond the industrial estate to the neighboring community, guided by the approach of Eco-Industrial Town. The community forest plantation project has been implemented continuously since 2020. In 2025, over 250 employee volunteers and local community members participated in planting 1,000 native tree species, such as tamarind, Siamese cassia, neem, and bullet wood. To date, a total of 8,000 trees have been planted, contributing to the expansion of green space within the community forest area.

In 2025, the Company, together with the AMATA City Chonburi Industrial Estate Office and over 60 tenants and operators within the industrial estate, organized a fish release and mangrove planting event for the fourth consecutive year to mark an official royal commemoration. This event was held to honor Her Majesty Queen Sirikit the Queen Mother on the auspicious occasion of her 93^rd birthday anniversary. Over 9,300 fish were released, and more than 1,000 mangrove trees were planted at the Mangrove Conservation Learning Center in Khlong Tamru, Chonburi Province. This initiative serves not only to enrich natural resources but also to diversify fish species, providing future food sources and livelihoods for the community.

AMATA City Rayong Industrial Estate is in the middle of a watershed, the Phu Sai Stream, which flows from the Khao Mai Kaeo watershed and runs through the industrial estate before reaching the Dok Krai Reservoir, which is a large reservoir with a capacity of over 79 million cubic meters and an area of more than 1,300 rai (2.08 square kilometers) in Rayong province. Although Dok Krai Reservoir is located outside the radius of 5 kilometers from AMATA City Rayong Industrial Estate, it is an area that is important in terms of freshwater ecosystems and an important economic source for the community because it is a nursery for aquatic animals and local fishing areas for more than 500 households in Nikhom Phatthana district. This poses a threat to aquatic species, a significant part of the community's traditional means of subsistence, and is prompting surrounding populations to be concerned about potential effects on water quality.

As a result, the Company collaborates with the Rayong Provincial Fisheries and Freshwater Fisheries Resource Management Group at Dok Krai Reservoir, a community committee that oversees and controls reservoir utilization. Additionally, the Company works with various alliance groups, such as local authorities and factory operators in AMATA City Rayong Industrial Estate, to develop the "Joint Development toward Sustainable Watershed” project. This project aims to preserve and restore water sources, including local aquatic animal species that provide a reliable source of income and food for the community and can also serve as effective water quality indicators.

In 2025, AMATA City Rayong Company Limited and AMATA U Company Limited, in collaboration with the Dok Krai Reservoir Fisheries Resource Management Group, Rayong Provincial Fisheries Office, and the Phana Nikhom Subdistrict Administrative Organization, organized the "Sustainable Water Resource Conservation (Fish Stocking) Project" to promote tripartite cooperation in conserving natural resources among the government, private sector, and local communities at the Dok Krai Reservoir, Rayong Province. This project involved over 430 volunteer employees from both inside and outside the industrial estate, as well as members of the community. Together, they released over 400,000 fish, including Chinese carp (Hypophthalmichthys molitrix), Indian carp (Labeo calbasu), Rohu carp (Labeo rohita), Mekong giant catfish (Pangasianodon gigas), Smallscale mud carp (Cirrhinus microlepis), and more than 200,000 Giant freshwater prawns (Macrobrachium rosenbergii). These species are native to the Dok Krai Reservoir and have been surveyed and identified by the Rayong Provincial Fisheries Office. Since the project's inception until 2025, the companies have released a total of over 3,730,000 fish and have continuously constructed fish homes, called "Sung,” using ropes, to provide shelters and increase survival opportunities for the released aquatic species, while also enhancing biodiversity in the fish home area in terms of both species and population.

In addition to preserving local species and increasing the number of aquatic animals in Dok Krai Reservoir, these activities have increased community confidence in the quality of water flowing through AMATA City Rayong Industrial Estate, which the Company has effectively managed, controlled, and monitored. In the future, the Company plans to conduct surveys on the diversity of aquatic animals in the Dok Krai Reservoir area in collaboration with Rayong Province Fisheries and the Dok Krai Reservoir Freshwater Fisheries Resource Management Group. This information will be used as basic information for biodiversity conservation efforts and future water quality assessments.

To ensure the effectiveness of biodiversity management measures, the Company has established monitoring and verification mechanisms, as outlined below:

• The Company requires regular reporting on compliance with environmental mitigation measures through Environmental Impact Assessment (EIA) reports submitted to relevant regulatory authorities every six months. In addition, the Company’s environmental team conducts random site inspections of contractors and business partners to ensure compliance with prescribed measures, prevent encroachment beyond project boundaries, and ensure pollution control is implemented in accordance with applicable laws and regulations.
• The Company has established community grievance channels for receiving complaints related to operational impacts, together with an effective grievance management mechanism to address and remedy impacts arising from the Company’s activities as well as those of its suppliers and contractors within specified timeframes. Where appropriate, the Company provides fair and equitable remediation to affected parties.
