Conspicuous consumption is the spending of money on and the acquiring of luxury goods and services to publicly display economic power—of the income or of the accumulated wealth of the buyer. Wikipedia
Conspicuous sustainability: the spending of money on and the acquiring of luxury sustainability goods, infrastructure and services to publicly display environmental piety and power—and the income or of the accumulated wealth of the buyer.
