While economic development is critical for lifting people out of poverty and raising living standards for the broader population, it also causes harmful side effects—particularly for the environment—with potentially sizeable costs for the macro-economy.
For example, rising atmospheric accumulations of greenhouse gases could substantially raise global temperatures, posing considerable risks. Poor air quality is a major human health problem. And road congestion can impose substantial burdens on urban economies, by reducing the productive time of the workforce.
Fiscal instruments (emissions taxes, trading systems with allowance auctions, fuel taxes, charges for scarce road space and water resources, etc.) can and should play a central role in promoting greener growth.
