Global evaluation of the natural environment and household income for sustainable development

With global economic growth, the burden on the natural environment is severe, and more and more attention is paid to sustainable development that enhances the economic growth and sustainability of the natural environment. This study aims to show the concern of global citizens regarding the natural environment and household income. It used worldwide individual interview data from 149 countries between 2007 and 2021, with 2,450,043 observations (Gallup World Poll surveys) and an original large-scale internet- and face-to-face-survey from 37 nations with 100,956 observations. Using a binary logit regression model, this study also analyzes public sentiment regarding who should bear the financial burden for environmental conservation. We found that 60 % of citizens showed that their current income provides a comfortable life; on the other hand, 49 % of the respondents were dissatisfied with conservation of the natural environment. The satisfaction with household income was much greater than satisfaction with natural environmental conservation, leaving space for improvement in environmental stringency. For citizens’ preferences regarding financial responsibility, the government and companies are expected to afford conservation costs.
