The air environment in Tokyo has improved, allowing
the environmental standards for PM2.5 to be met at all
monitoring stations for the first time in FY 2019. However,the concentration of photochemical oxidants still exceeds
environmental standards.

Air Pollution Monitoring System

Recent Efforts
As the concentration of PM2.5 and photochemical oxidants has to be lowered, TMG is working on measures toreduce emissions of the causative agents, including volatile organic compounds (VOCs) and nitrogen oxide (NOx).
As the environmental standards for PM2.5 were met at all monitoring stations in FY 2019, we will aim to achieve3

the world’s strictest index of 10 μg/m (average of all monitoring stations) stipulated by WHO by FY 2030.

TMG has installed air pollution
monitoring equipment at 82 locations
in Tokyo for 24-hour continuousmonitoring.
Measurements are updated on anhourly basis on air pollution maps on thewebsite of the Bureau of Environment.

Enforcement of Diesel Regulations
CLEAN AND COMFORTABLE AIR

To ensure effective enforcement of diesel regulations, a team ofautomobile pollution inspectors, mainly former police officers, aredispatched to identify vehicles in violation. Enforcement of theregulations involves the team carrying out inspections of vehicles on
the street and at distribution centers, and theuse of video cameras to record vehicles drivingin Tokyo. Violators are subject to an orderprohibiting operation of the vehicle. In theMeasures against Diesel Emissions

case of a repeated offense, a fine is imposed.

Recording number plates to identify noncompliant vehicles

Since 2003, TMG has been regulating exhaust gas from diesel vehicles in accordance with ordinances. Diesel
vehicles subject to the regulation include large vehicles, such as trucks and buses. Passenger vehicles are exempt.
Since the beginning of the regulation, diesel vehicles that do not meet the particulate matter (PM) emission
standards stipulated by the ordinances have not been allowed to be driven in the metropolitan area. These diesel
vehicles must be replaced with low-emission vehicles or equipped with PM reduction devices that meet TMG
specifications in order to satisfy the regulation.

Reducing Environmental Load of Business Vehicles
In addition to a crackdown against non-compliant
diesel vehicles, TMG is now working to support theTo boost the start of the regulation, TMG strongly urged auto manufacturers to develop PM reduction devices
and the oil industry to supply low-sulfur light oil while consolidating crackdown systems and providing financial
support to users. As a result, the air environment in Tokyo has drastically improved since 2004 in terms ofshift to hybrid buses and trucks, etc.
