Written Reply to Parliamentary Question on emissions self-testing facility by Ms Grace Fu, Minister for Sustainability and the Environment.
Question:
Dr Charlene Chen: To ask the Minister for Sustainability and the Environment in respect of the emissions self-testing facility for motorcycles at Woodlands Checkpoint (a) what measures are in place to ensure proper usage, accuracy and prevent tampering; (b) what is the pass and fail rates to date; and (c) how are riders being selected or incentivised to participate in these tests.
Answer:
The National Environment Agency (NEA) conducted a three-month trial of the emissions self-testing facility for motorcycles at Woodlands Checkpoint from November 2023 to February 2024. Riders were randomly selected and directed to the self-testing kiosk, where step-by-step instructions were provided on a screen to guide the riders in conducting the test. The conduct of the test was monitored by NEA officers stationed on site to ensure proper test procedures were followed. Around 700 motorcycles underwent self-testing, with enforcement action taken against the approximately 230 that exceeded in-use exhaust emission limits. NEA is exploring further enhancements to the self-testing facility to improve usability and scalability.
