Project Implementation Results - Abstract
Mobile air pollution sources are one of the main factors
responsible for the degradation of air quality in urban areas, and as
such are the focus of increasingly rigorous controls by the
environmental and transportation authorities. In particular, the
exhaust emissions of two-stroke engine motorcycles and old
motorcycles, and the black smoke emitted by diesel vehicles, are a
major source of concern to the general public. To ensure that
management of mobile pollution sources is as comprehensive as
possible, in the current fiscal year the Environmental Protection
Department, New Taipei City Government has been focusing on
mobile pollution source inspection operations. The Department has
been making use of Big Data analysis to identify stretches of road that
suffer from particularly high levels of air pollution, in order to make
roadside inspections more effective in identifying highly-polluting
vehicles. In addition, patrols and license plate recognition technology
have been utilized to increase the percentage of motorcycles brought
in for periodic inspection, and visual inspection of exhaust fumes has
been used as a basis for notifying suspected highly-polluting diesel
vehicles to report for inspection. Through these measures, the
Department is working to encourage citizens to get into the habit of
performing regular maintenance work on their motor vehicles.
In order to ensure that highly-polluting vehicles are scrapped,
and foster environmental awareness among the general public, the
Department has been implementing the Clean Air Zone strategy. In
the first wave of Clean Air Zone implementation, New Taipei City
Government gave formal notification of the establishment of Clean
Air Zones in New Taipei City’s ShuangXi District, PingXi District,
GongLiao District and RuiFang District. In the second wave of
implementation, the four districts within New Taipei City that have
the largest number of registered two-stroke motorcycles were
designated as traffic hotspots. In August 2017, an official notification
was issued stipulating that drivers of two-stroke motorcycles within
Clean Air Zones in BanQiao District, SanChong District, ZhongHe
District and XinZhuang District who failed to bring their motorcycles
in for periodic inspection would be subject to fines of NT$2,000, and
that the City Government would be stepping up visual inspection and
roadside inspection operations targeting diesel vehicles that do not
display the appropriate Environmental Protection Administration
(EPA) issued badge; diesel vehicles that were inspected and found not
to meet exhaust emissions standards would be subject to a fine of
NT$30,000 – 50,000.
With regard to pollution self-management agreements signed
with business enterprises, and the special controls implemented at the
Port of Taipei, this year’s plan made use of fixed pollution source
pollution reduction consultations. For example, the Nan Ya Group
was asked to begin imposing restrictions on contractors’ vehicles so
that, starting from January 1, 2017, contractors’ vehicles that are more
than five years’ old would be required to display a low-polluting
vehicle badge issued by the EPA in order to be allowed to enter Nan
Ya Group facilities. License plate recognition analysis showed that,
following the implementation of these new controls, the percentage of
non-conforming vehicles fell from 11.8% to 0.5%. In addition, license
plate recognition analysis has shown that, following the adoption of
various types of inspection and control measures at the Port of Taipei,
low-polluting vehicles’ share of all vehicles entering and leaving the
Port rose to 92.1%. Further analysis of vehicle types (in terms of
exhaust emissions) showed that the share of all vehicles entering or
leaving the Port held by period I and period II (superannuated)
vehicles had fallen by 4.8% compared to FY2016, and was 5.9%
lower than the share of all registered vehicles falling into that
category, indicating that the number of highly-polluting vehicles
actually on the roads may be lower than the number of such vehicles
that are registered as being in use.
To summarize, implementation of the various inspection and
control measures outlined above led to a reduction in carbon
monoxide emissions of 290.12 tons, a reduction in hydrocarbons of
39.45 tons, a reduction in PM10 particulate matter of 60.67 tons, and
a reduction in PM2.5 fine particulate matter of 48.53 tons.
