汽車廢氣是本港路邊空氣污染的元兇。為加強監測，環境保護署計劃興建一個永久實驗室，專門進行便攜式廢氣測量系統（PEMS）的測試，以便與國際發展和技術水平接軌。

We also evaluate the performance of the latest vehicle technologies over time, especially the performance of after-treatment devices and build up a local in-use vehicle emission database by portable emission measuring systems (PEMS) that can account for the emission design standards, operating conditions and engine conditions of local vehicles.
