Environmental performance at a glance

About this report

Reporting basis

This targeted report has been prepared with reference to selected GRI Standards. It does not claim to have been prepared in accordance with the GRI Standards. The GRI Content Index on pages 7-8 identifies the disclosures and selected information reported.

ENVIRONMENTAL MANAGEMENT

ISO 14001 provides the management foundation

ATT Systems maintains an environmental management system certified to ISO 14001:2015. SOCOTEC certificate SCS 102652EI-1 covers the design, development, integration and maintenance of electronics and computer systems, including electronic display, queue management, security management, traffic management, system integration and customized software solutions. The certificate is valid until 17 December 2027, subject to ongoing surveillance.

Governance and review

• The Quality, Environmental, Occupational Health and Safety Policy was approved by a Director on 9 November 2023 and reviewed at the management review meeting on 30 September 2025.
• A full-system internal audit covering ISO 9001, ISO 14001 and ISO 45001 clauses 4 to 10 was conducted from 18 to 29 August 2025, with no corrective action request raised.
• The external surveillance and recertification audit was conducted in October 2025. The audit recommended maintenance of ISO 14001 certification and raised no nonconformity or observation.

Managing environmental impacts

Environmental aspects and impacts are managed through operational controls, internal audits and management review. Sampled controls recorded in the October 2025 external audit included:

• waste disposal procedures and records for general waste, recyclable waste, e-waste and chemical waste;
• scrap collection, licensed disposal of oils and lubricants, dust and noise controls, vehicle servicing and environmental awareness activities; and
• internal targets of zero complaints due to air or land pollution and zero environmental legal non-compliance for the period reviewed by the auditor.

Reported environmental topics

PERFORMANCE

Purchased electricity: 219.18 MWh

ATT Systems consumed 219,179.57 kWh of purchased electricity at 35 Ubi Crescent over 12 consecutive electricity billing cycles from 10 July 2025 to 9 July 2026. This is equivalent to 219.18 MWh or 789.05 GJ.

Figure 1. Purchased electricity by bill month. Detailed billing data is provided on page 10.

Method

The total is based on 12 SP Services bills for electricity account 9301146412. The conversion applied is 1 kWh = 0.0036 GJ. The bills contain no indication that electricity consumption was estimated.

Management approach

Electricity consumption is monitored through utility bills and managed through the environmental management system, including equipment and operating controls. A complete greenhouse gas inventory has not yet been prepared; therefore, this report does not present Scope 1 or Scope 2 greenhouse gas emissions.

PERFORMANCE

Third-party water withdrawal: 0.7584 ML

ATT Systems recorded 758.4 m3 (0.7584 ML) of third-party water withdrawal supplied through the Public Utilities Board over 12 consecutive water billing cycles from 11 July 2025 to 9 July 2026.

Figure 2. Third-party water withdrawal by bill month. Detailed billing data is provided on page 11.

Reporting scope

Selected information from GRI 303-3 is reported for third-party water withdrawal. The available bills do not classify the supply by source, freshwater/other water or water-stress status. Billed withdrawal is not presented as net water consumption because discharge data is unavailable.

Management approach

Water use is monitored through utility bills and managed through maintenance and resource-conservation practices under the environmental management system.

CONTROLS AND NEXT PRIORITIES

Waste controls are in place

ATT Systems has documented controls for general waste, recyclable waste, e-waste and chemical waste. The environmental management system includes waste disposal procedures, scrap collection arrangements, an e-waste bin, monitoring records and the use of licensed waste management companies where applicable.

Priorities for the next reporting cycle

1. Establish a controlled annual environmental data register for electricity, water, fuel, refrigerants and each waste stream, with named data owners and source documents.
2. Confirm the organizational reporting boundary across ATT Group entities and operating sites before the next report.
3. Develop a greenhouse gas inventory using an approved methodology and current Singapore electricity emission factors.
4. Set measurable environmental targets after establishing a complete baseline. Any future SBTi claim will only be made after formal validation.
5. Publish environmental performance annually and progressively expand the GRI disclosures as data quality and governance mature.

Management commitment

ATT Systems is committed to maintaining its ISO 14001 environmental management system, complying with applicable environmental requirements, preventing pollution, conserving resources and continually improving its environmental performance and reporting practices.
