Background

It is crucial to control mobile pollution sources because they emit various harmful substances, such as nitrogen oxides (NOx), sulfur oxides (SOx), and hydrocarbons (HC), etc., that cause odors, acid rain, and smoke. Currently, countries of the world control of fuel composition of mobile pollution sources more strictly, and Taiwan is keeping pace with such global efforts.

Standards for the Composition of Mobile pollution source Fuels

In order to well control the quality of fuel source, on March 20, 2020, the MOENV amended and promulgated " Standards for Controlling Fuel Composition of Mobile Pollution Sources", and implement since July 1, 2020, the main contents are as follows.

• Amend the benzene content of gasoline from 1.0 % (v/v) to 0.9 % (v/v) and will phrase strict it to 0.8 % (v/v) on 2024.
• Amend the polycyclic aromatic hydrocarbons (PAH) content of diesel from 11 % (m/m) to 8 % (m/m).
• Add standards to control the sulfur content of marine fuel and aviation fuel, 0.5 % (m/m) and 0.2 % (m/m) respectively, in an effort to reduce hazard to human health and air pollution from non-road mobile pollution sources.

Sampling inspection of mobile pollution source fuels

According to the "Sales and Import Permits and Management Measures for Fuels used by Mobile Pollution Sources," the above-mentioned fuels must not only meet the fuel standards and must also obtain a permit from the MOENV in accordance with the regulations, so that fuels can be sold and imported in accordance with the permit documents. The manufacturer or importer should conduct sampling and testing of each batch of fuel, and the competent authorities at all levels must check relevant data or test fuel in the manufacturer's or importer's factory or field, product storage tanks, oil depots, sales locations or other public and private place by their own or entrust professional institutions.
