The inner-city inhabitants and foreigners' contribution commitment to improving air pollution in Hanoi, Vietnam
Science-based desirable solutions for mitigating and or reducing environmental pollution are of important priorities for many developed and developing countries. In this dataset, we concentrate on studying contribution commitments and factors influencing interviewees' willingness-to-pay to reduce air pollution by using a contingent valuation method. We employed a stratified random sampling technique with a face-to-face approach to survey 199 inhabitants and 75 foreigners who reside and travel within the inner-city of Hanoi, the capital of Vietnam - an emerging country in Southeast Asia. The dataset comprises four major groups of information including (1) perception of air pollution and its impacts, (2) preventive measures used to mitigate polluted air, (3) commitments on willingness-to-pay (WTP) for reducing air pollution alongside reasons for the yes-or-no-WTP decisions, and (4) demographic information of interviewees. The data could bring many attributes and policy implications for better economics and environmental management in the study area and or in similar places around the world.
