The Result of Legislative Measure in the Control Pollution from Automobile in Thailand

Abstract

   This research examines the efficiency of legislative measure in the control pollution and their influence on the automobile industry in Thailand. The research utilizes pollution and automotive industry data from 2011 to 2022 dividing the data into two periods: 2011-2015 and 2016-2022, reflecting the time before and after the implementation of policies promoting energy-efficient and eco-friendly car. Findings show that emissions of sulfur dioxide (SO_₂), nitrogen dioxide (NO_₂), and carbon monoxide (CO) significantly decreased after the implementation of the policy. In contrast, carbon dioxide (CO_₂) emissions increased over the same period, even during the COVID-19 pandemic in 2020, which temporarily massive reduced in car usage in Thailand. These results suggest that Thailand's legal measures for controlling automotive pollution may not be as effective as anticipated. However, they indicate a shift in consumer behavior towards purchasing vehicles with diesel engines, hybrid engines, and electric vehicles (EVs), moving away from traditional gasoline engines.
