Abstract

Petaling Jaya as a core hub of the Klang Valley and a leading development centre in Selangor has a heavy carbon footprint from mobile sources. As a result this study identifies residents attitudes toward air emissions their preferences for improvement and measures the marginal importance of the attributes for improving urban air quality. 300 residents from four zones; Seksyen SS PJU and PJS were selected using stratified and systematic random sampling method. They were evaluated on their attitudes using a Likert scale and preferences using a discrete choice experiment. According to descriptive analysis respondents favour driving to using public transportation but their overall attitude toward mitigating air emissions is favourable. Residents embraced an increase of 70 in carpooling initiative participation 70 in indoor planting programme participation four low emission zones and six electric buses according to the results of a random parameter logit model for the choice experiment. Based on 194 205 households the marginal willingness to pay the value in PJ was calculated to be about RM33/household/month to RM6 408 765.00/month in 2019. Residents would place a higher priority on environmental concerns if air quality improved. As a result attempts to increase air quality may function as a benchmark for all urban cities.
