EXPLANATORY NOTE 
The bill proposes the amendment of Section 21 (b) and (d), Article IV of Republic Act 
No. 8749 or the "Philippine Clean Air Act of 1999” which originally excludes the 
government- its agencies, departments, and local government units- from the list of 
entities allowed to conduct emission testing on vehicles, including its own. 
The pertinent provision currently reads as: 
Article IV 
Pollution from Motor Vehicles 
Section 21. Pollution from Motor Vehicles. – 
b) The Department, in collaboration with the DOTC, DTI and LGUs, shall
develop an action plan for the control and management of air pollution from
motor vehicles consistent with the Integrated Air Quality Framework. The DOTC
shall enforce compliance with the emission standards for motor vehicles set by
the Department. The DOTC may deputize other law enforcement agencies and
LGUs for this purpose. To this end, the DOTC shall have the power to:
(1) Inspect and monitor the emissions of motor vehicles;
(2) Prohibit or enjoin the use of motor vehicles or a class of motor vehicles in
any area or street at specified times; and
(3) Authorize private testing emission testing centers duly accredited by the DTI.
d) In order to ensure the substantial reduction of emissions from motor vehicles,
the Department of Trade and Industry (DTI), together with the DOTC and the
Department shall formulate and implement a national motor vehicle inspection
and maintenance program that will promote efficient and safe operation of all
motor vehicles. In this regard, the DTI shall develop and implement standards
and procedures for the certification of training institutions, instructors and
facilities and the licensing of qualified private service centers and their

technicians as prerequisite for performing the testing, servicing, repair and the 
required adjustment to the vehicle emission system. The DTI shall likewise 
prescribe regulations requiring the disclosure of odometer readings and the use 
of tamper-resistant odometers for all motor vehicles including tamper-resistant 
fuel management systems for the effective implementation of the inspection and 
maintenance program. 
 
It appears from the aforecited Section that the only private parties may be certified by 
the Department of Transportation and Communications (DOTC), now Department of 
Transportation (DOT), to conduct emission testing on vehicles plying public roads. 
Consequently, even the government has to pay third-party service providers to have 
its service vehicles assessed, costing the government significant but unnecessary 
expense as the government is sufficiently equipped with the mechanism and 
personnel to test its own vehicles. 
 
In consideration of the foregoing, as well as the pressing need of the State to sustain 
its long-term infrastructure projects, this Representation believes that amending the 
provision shall help the government save reduce its expenditures. The amount saved 
is urged to be utilized instead to bolster the economy and serve the welfare of the 
people. The passage of this bill is humbly sought.
